The invention discloses a multi-system-oriented configurable metadata storage method, which comprises the following steps of: creating a tmapping table and a tcaltype table in a database, and presetting a specific value which needs to be converted; creating three java classes which are respectively used for reading the data in the two sheets of the table; the method comprises the following steps: creating a CodeMappingGroup class, and creating a hashmap set; the method comprises the following steps: creating a ConvertService class, and creating three attributes; the method comprises the following steps of: inheriting an InitializingBean interface by using a ConvertService class, and realizing an init () method; and a Convert Service class is used for realizing a Convert method. According to the invention, an efficient, flexible and maintainable field value conversion solution is provided in combination with database-based mapping relation management in an annotation-driven manner.

An apparatus provides an operating system service that receives, from an application in a batch environment, a plurality of database transactionality calls associated with a first program of the application, the first program having a first addressability mode. In response to at least one of the plurality of database transactionality calls, the operating system service provides a shared database connection to a database for the first program of the application and for a second program of the application that has a different and second addressability mode. In some implementations, the operating system service provides the shared database connection using one or more of a plurality of callable database transactionality classes, such as a plurality of callable Java classes in a Java archive (JAR) file.

The present invention discloses an Excel table import and export method and device based on apache.poi, which relates to the field of java technology applications; based on apache.poi, an Excel table import and export method is provided using java classes, wherein the Excel table import method includes an import method without sheet page selection and an import method with sheet page selection, and the Excel table export method includes an export method without custom sheet page names and an export method with custom sheet page names. The method of the present invention simplifies the operation of importing and exporting excel tables, and can realize the import or export of data by passing in fewer parameters.

The invention discloses a WSDL-based server API automatic construction method and device and a medium, and relates to the technical field of information system development, and the method comprises the following steps: determining a type mapping rule according to a JSON data structure; based on a JSON data structure and a type mapping rule, obtaining a Java data class file through automatic recursion processing of a Java naming rule; performing abnormal state analysis on the Java data file to determine a file abnormity solution; according to the Java data class file, obtaining a standard annotation through service class annotation labeling; constructing a service skeleton conforming to a JAX-WS specification for the standard annotation to determine a directly recognizable service class; and dynamically compiling the directly recognizable service class to obtain a dynamic deployment service. According to the method, the technical problems that the Java class cannot be automatically derived from any JSON example and the WebService cannot be automatically constructed and deployed in the prior art are solved.

The invention relates to / belongs to the technical field of data processing, and particularly relates to a method, a system and equipment for converting an XML document into an object and a storage medium. The method aims at solving the problems that in the prior art, Java classes generated by JAXB are not optimized or cannot meet the requirements of developers; and processing of large or complex XML documents is too complex. Comprising the steps that an XSD file of an XML document is obtained and analyzed, and XSD analysis data is obtained; configuring corresponding rule data by using a rule configurator; the XSD analysis data and the rule data are added into a template engine, code filling is carried out, and a JAVA class is generated; configuring a JAXB context instance; the method comprises the following steps of: creating a Unmarshaller instance by utilizing a Unmarshaller interface of JAXB, and carrying out deserialization operation on an XML (Extensible Markup Language) document on the basis of the Unmarshaller instance, so as to obtain a Java object.

The embodiment of the invention provides a Java memory horse detection method and device, a medium and electronic equipment. The method comprises the steps of performing security scanning on Java classes in a Java virtual machine at preset time intervals according to a security plug-in instrumented in a target program; in each security scanning, based on a predetermined identification rule, identifying a Java class to be detected from all the scanned Java classes; obtaining class information of each Java class to be detected; matching the class information of each to-be-detected Java class with sample information of a known memory horse one by one, and determining the similarity between the class information of the to-be-detected Java class and each piece of sample information; and if the similarity between the to-be-detected Java class and any piece of sample information is greater than or equal to a preset threshold value, determining that the to-be-detected Java class is a malicious class. According to the technical scheme provided by the embodiment of the invention, the detection efficiency of the memory horse can be improved while the computing resources occupied by the memory horse can be reduced.

This invention discloses a cloud-based distributed report computing method, belonging to the field of big data technology. It includes decomposing and defining the data retrieval expressions of report cells, breaking down report tasks into several sub-tasks, allocating and sending the sub-tasks to remote data retrieval nodes, and having the remote nodes dynamically load JAVA classes based on the data retrieval formula encoding and execute specified methods to return to the server. A global MAP cache based on KEY-VALUE format is generated. By iteratively replacing formulas and parameter values ​​in the indicator data retrieval expressions, and using the FEL script engine to calculate the numerical expressions, the calculation of all report task indicators is generated. This solves the technical problems of automatically decomposing fixed report data retrieval tasks based on data retrieval formulas and parameters, and automating the remote allocation and control of report data retrieval tasks. It reduces the difficulty of report configuration, greatly improves report computing efficiency, and achieves parallel report computing.
