Exception Handling Method for Multiple Application Module Clients in the Same Process

Abstract

The invention relates to an exception handling method for a multi-application module client in the same process. The exception handling method comprises the following steps of building functional units; building an application program domain for each functional unit Mi in boarding process P of a system S by the system S; boarding each functional unit in the corresponding application program domain; integrating each application program domain and the corresponding functional unit by the system; boarding the system and the functional units in a single process; carrying out data transfer among different functional units by a data transfer method crossing the application program domains when service relevance exists among different functional units; and downloading the functional unit by the system when the functional unit is abnormal. By the exception handling method, the influence range due to abnormality of the system can be effectively controlled, all functional modules are safely separated, the system safety is guaranteed, and the system stability is improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to an exception handling method for multi-application module clients under the same process. Background technique [0002] According to the actual business needs of different enterprises, the production process management information system can generally be divided into a number of different functional modules. It is required to dynamically load each sub-function module into the system. [0003] Although the appeal development method is flexible, the system has a large security risk. When the developer of a sub-module does not fully integrate its internal exception handling into the system, when the sub-module throws an exception, the exception problem will be transmitted to the entire system , causing the entire system to fail to function properly. Different sub-modules run in the same process and can access each other's data, which may easily cause misoperation of data and ...

[0003] Although the appeal development method is flexible, the system has a large security risk. When the developer of a sub-module does not fully integrate its internal exception handling into the system, when the sub-module throws an exception, the exception problem will be transmitted to the entire system , causing the entire system to fail to function properly

Different sub-modules run in the same process and can access each other's data, which may easily cause misoperation of data and throw business logic exceptions, while the production process management information system requires system stability and correctness of business logic Higher, the stagnation of the system will cause great troubles for on-site production
