Description

Technical Field

[0001] The present application relates to the technical field of application migration, and in particular to a method and device for cross-platform conversion of EJB applications based on an application server. Background Art

[0002] EJB applications refer to applications that can be deployed in EJB containers. The EJB container is part of the Java EE server and is mainly responsible for managing the life cycle of EJBs, providing resources, handling transactions and security, etc. When deploying EJB applications, in order to enable the EJB applications to meet the corresponding requirements, it is necessary to configure the EJB application information through deployment descriptors.

[0003] Since EJB applications usually require customized deployment descriptor configuration for specific application servers, such as transaction attributes, security constraints, resource references, etc., which usually exist in the form of XML files. Different manufacturers or models of servers have different interpretations and processing methods for these configuration information. Therefore, when migrating EJB applications to a new application server, the new application server to be migrated must be reconfigured to adapt to the new application server.

[0004] However, reconfiguring and modifying the migrated new application server is not only cumbersome, increasing the development and maintenance costs, but also prone to errors, making the application configuration different from the previous one, resulting in failure to meet usage requirements or unavailability.

[0064] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0065] In this application, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0066] The present application embodiment provides a cross-platform conversion method for EJB applications based on an application server, such as Figure 1 As shown, the specific steps include:

[0067] S101 . When migrating and deploying a current target application to a target application server, identify the type of the current target application.

[0068] The current target application refers to any application that needs to be migrated currently, and the target application server is the server of the migration destination.

[0069] It should be noted that applications can be divided into WEB applications and EJB applications. Since the architectures of the two applications are different, the specific operations during migration are also different. The application migration method provided in this application is mainly for EJB applications, which can be ".jar" type applications or ".ear" type applications. Therefore, in order to perform corresponding migration operations on EJB applications, when there is a current target application that needs to be migrated and deployed, it is necessary to first identify the type of the current target application.

[0070] Specifically, the migration deployment of the current target application can be started by using the application server management console or the external interface provided by the application server, and the type of the current target application will be identified at this time.

[0071] Optionally, the judgment may be made based on the output information of the current target application, or directly based on the deployment file of the current target application, so that no other additional operations are required. Of course, other methods may also be used for judgment.

[0072] Optionally, in another embodiment of the present application, a specific implementation of step S101 is as follows: Figure 2 As shown, the following steps are included:

[0073] S201, scanning each sub-file in the deployment file of the current target application deployment.

[0074] Optionally, the deployment file of the current application deployed to the target application server may be parsed to obtain each sub-file therein, and then the name and type of each sub-file of the deployment file may be scanned.

[0075] S202: Determine whether each standard specification file of the EJB application exists in each sub-file in the scanned deployment file of the current target application deployment.

[0076] It should be noted that for EJB applications, there must be some corresponding standard specification files, which are different from files of other applications, such as "META-INF / ejb-jar.xml" and "sun-ejb-jar.xml", etc. Therefore, in the implementation of this application, based on the information of each sub-file in the scanned deployment file, it is determined whether there are various standard specification files of the EJB application in each sub-file in the deployment. Among them, if it is determined that there are various standard specification files of the EJB application in each sub-file in the scanned deployment file deployed by the current target application, step S203 is executed. If it is determined that there are no various standard specification files of the EJB application in each sub-file in the scanned deployment file deployed by the current target application, it means that it does not belong to an EJB application, but a WEB application, and step S204 is executed at this time.

[0077] S203: Determine whether the current target application is an EJB application.

[0078] S204: Determine whether the current target application is a WEB application.

[0079] S102: Determine whether the type of the identified target application is an EJB application.

[0080] If it is determined that the type of the identified target application is an EJB application, that is, if it is identified that the current target application belongs to an EJB application, step S103 is executed.

[0081] S103: Detect deployment description information of the current target application from the deployment file of the current target application deployment.

[0082] It should be noted that since this solution is mainly to achieve adaptive conversion of deployment description information of EJB application during migration and deployment, it is necessary to obtain its deployment description information first before conversion. Therefore, it is necessary to detect the deployment description information of the current target application from the deployment file of the current target application deployment.

[0083] Specifically, the deployment file may be scanned to detect key configuration files belonging to the EJB application in the current target application, and the deployment description information of the current target application may be read therefrom.

[0084] S104: Determine the information description type to which the deployment description information of the current target application belongs and the information description type corresponding to the target application server.

[0085] Optionally, the information description type corresponding to the deployment description information required by each type of server can be configured in advance for the interpretation and processing methods of each type of server, that is, the information description type corresponding to each type of server can be obtained. The types of servers can be divided according to information such as manufacturers and models.

[0086] Therefore, the type of the target application server can be obtained first, and then the information description type corresponding to the target application server can be determined based on the type of the target application server. As for the information description type to which the deployment description information of the current target application belongs, the server type of the current target application before migration can be determined first, and then the information description type corresponding to the server type can be determined. Since the deployment description information of the current target application is adapted to the server before migration, the information description type corresponding to the server is the information description type to which the deployment description information of the current target application belongs.

[0087] Of course, the correspondence between each information description type and the format of its deployment description information may also be configured in advance, so that the information description type to which the deployment description information of the current target application belongs can be directly determined according to the format of the deployment description information of the current target application.

[0088] S105. According to the descriptor of the information description type to which the deployment description information of the current target application belongs and the mapping rule of the information description type corresponding to the target application server, the deployment description information of the current target application is converted into information of the information description type corresponding to the target application server to obtain the converted description information of the current target application.

[0089] It should be noted that in the embodiment of the present application, the mapping relationship between each descriptor between each information description type is pre-configured, so it is possible to directly convert each descriptor in the deployment description information of the current target application into a descriptor of the information description type corresponding to the target application server according to the mapping rule between the descriptor of the information description type to which the deployment description information of the current target application belongs and the information description type corresponding to the target application server, thereby obtaining the converted description information of the current target application.

[0090] Optionally, in another embodiment of the present application, a specific implementation of step S105 is as follows: Figure 3 As shown, the following steps are included:

[0091] S301: Find a target mapping rule from a conversion rule library according to the information description type to which the deployment description information of the current target application belongs and the information description type corresponding to the target application server.

[0092] The target mapping rule is a mapping rule between the descriptor of the information description type to which the deployment description information of the current target application belongs and the descriptor of the information description type corresponding to the target application server.

[0093] S302: Parse the deployment description information of the current target application to obtain each descriptor to be converted in the deployment description information of the current target application.

[0094] S303: Find out conversion information corresponding to each to-be-converted descriptor from the target mapping rule.

[0095] S304: Convert each descriptor to be converted into a corresponding descriptor in its corresponding conversion information to obtain conversion description information of the current target application.

[0096] S106: Using the conversion description information of the current target application, complete the migration and deployment of the current target application to the target application server.

[0097] Specifically, after obtaining the conversion description information of the current target application, the conversion description information of the current target application can be directly deployed to the target application server. The conversion description information of the current target application conforms to the information description type corresponding to the target application server, so the work of migrating the current target application to the target application server can be directly realized.

[0098] Optionally, in order to ensure that the current target application is available after being migrated to the target application server, in another embodiment of the present application, before executing step S106, the following may be further performed:

[0099] Check the compatibility of the conversion description information of the current target application with the target application server.

[0100] If it is detected that the conversion description information of the current target application is compatible with the target application server, it means that the conversion description information of the current target application is migrated to the target application server and is available, so the current target application can be used normally on the target application server. Therefore, step S106 is executed at this time.

[0101] If it is detected that the conversion description information of the current target application is incompatible with the target application server, a prompt message is fed back.

[0102] The prompt information is mainly used to prompt that the conversion description information of the current target application is incompatible with the target application server, and may also include incompatible information and reasons.

[0103] Optionally, in another embodiment of the present application, a specific implementation method of detecting the compatibility of the conversion description information of the current target application with the target application server includes:

[0104] Check whether there are descriptors that have not been successfully converted in the conversion description information of the current target application.

[0105] It should be noted that the main reason for incompatibility is that there is information in the conversion description information of the current target application that does not belong to the information description type corresponding to the target application server. Since the information format conversion was previously performed, it means that there are descriptors that have not been successfully converted. Usually, it is because there are erroneous descriptors in the deployment description information of the current target application, so it is impossible to determine the descriptors that need to be converted, and then the conversion cannot be performed. Of course, it may also be due to problems in the conversion program, resulting in the possibility of conversion failure. Therefore, by detecting whether there are descriptors that have not been successfully converted in the conversion description information of the current target application, it is determined whether the conversion description information of the current target application is compatible with the target application server.

[0106] Optionally, when performing descriptor conversion, the status of each descriptor conversion is recorded respectively. If the conversion is successful, the status is set to the status of successful conversion, so that it can be determined whether there are descriptors that have not been successfully converted according to the status of each description, and each descriptor that has not been successfully converted can be determined so that targeted processing can be performed. Of course, it is also possible to detect whether there are descriptors that have not been successfully converted in the conversion description information of the current target application by comparing before and after the conversion, or by performing format judgment.

[0107] Therefore, if it is detected that there is any descriptor that has not been successfully converted in the conversion description information of the current target application, it is determined that the conversion description information of the current target application is incompatible with the target application server.

[0108] If it is detected that there is no descriptor that has not been successfully converted in the conversion description information of the current target application, it is determined that the conversion description information of the current target application is compatible with the target application server.

[0109] The embodiment of the present application provides a cross-platform conversion method for EJB applications based on an application server. When the current target application is migrated and deployed to the target application server, the type of the current target application is first identified so that the EJB application can be migrated and deployed in a targeted manner. Therefore, if it is identified that the current target application belongs to an EJB application, the deployment description information of the current target application is detected from the deployment file deployed by the current target application. Then the information description type to which the deployment description information of the current target application belongs and the information description type corresponding to the target application server are determined. And according to the descriptor of the information description type to which the deployment description information of the current target application belongs and the mapping rule of the information description type corresponding to the target application server, the deployment description information of the current target application is converted into the information of the information description type corresponding to the target application server, and the conversion description information of the current target application is obtained, thereby realizing the adaptive conversion of the deployment description information of the current target application into the information adapted to the target application. Finally, the conversion description information of the current target application can be used to complete the migration and deployment of the current target application to the target application server, thereby realizing a simple method for migration and deployment of EJB applications, which not only makes EJB applications convenient, but also avoids errors.
