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 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.

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.
