Embodiment Construction

[0044] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] One of the core concepts of the embodiment of the present invention is to flexibly customize the class path and logic to be loaded by using a self-defined class loader isolation mechanism, so that the class files that the application server needs to load and the class files that are deployed on the application server The class files that the application needs to load are isolated to improve the fault tolerance of the application server and enhance the compatibility and stability of the application server.

[0046] Referring to FIG. 2 , it shows a flowchart of a method embodiment of class loading isolation of the present invention, which specifically includes the following steps:

[0047] Step 201, start a Java process, and ...

Abstract

The invention discloses a method of class loader isolation. The method is as follows: start up Java process and create therein a user-defined class loader object; add a class path in the user-defined class loader object; create a startup application server thread object and appoint the user-defined class loader object for the class path; and then start up the startup application server thread object. The invention flexibly defines the class path and logic to be loaded by making use of the user-defined class loader isolating mechanism, so as to separate the class file to be loaded by the application server, with the class file to be loaded by the applications deployed on application server. Therefore, the invention can strengthen fault tolerance, compatibility and stability of application servers.

Description

technical field [0001] The invention relates to the class loading isolation field of Java, in particular to a Java virtual machine-based class loading isolation method and a class loading isolation device. Background technique [0002] At present, in the Internet / Intranet / Extranet environment, most enterprise-level application systems adopt three-tier or multi-tier application modes. In order to facilitate the development, deployment, operation and management of applications based on multi-layer structure, it is necessary to build a complete application framework based on the underlying technology of network and distributed computing, and provide corresponding supporting platforms as the infrastructure of multi-layer applications. The key to supporting the platform is the application server in the middle layer. Application server is a platform for creating, deploying, running, integrating and maintaining multi-tier distributed enterprise applications. In enterprise applica...
