Embodiment Construction

[0069] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0070] As described in the background technology, in the loading mechanism of parent delegation, the bootstrap class loader (BootstrapClassLoader): is responsible for loading the JAVA_HOME\lib directory, or in the path specified by the -Xbootclasspath parameter, and is recognized by the virtual machine (identified by file name) , such as rt.jar) class. Extension C...

Abstract

The embodiment of the invention discloses a class loading method and device. The method comprises the following steps: obtaining a class loading request of an application module, and enabling the class loading request to carry the attribute configuration information and class loading configuration information of the application module; determining a target class loader from a plurality of class loaders according to the class loading configuration information, wherein the plurality of class loaders include a non-custom class loader and a plurality of custom class loaders, and each custom class loader has at least two custom loaders as parent class loaders; controlling the target class loader to process the class loading request according to the attribute configuration information; and returning a processing result of the class loading request to the application module. Therefore, the class loading method provided by the embodiment of the invention breaks through the limitation of a loading mechanism delegated by parents, the class loading request can be processed according to the requirements of the application module, and the dynamic requirements of multiple modules on the class loading request can be met.

Description

technical field [0001] The present application relates to the computer field, in particular to a class loading method and device. Background technique [0002] As the functions of an application system continue to enrich, it is necessary to modularize the application system with multiple functions, that is, each module corresponds to a function in the application system, and each module is an independent business function. For example, if the bank application system can provide two functions of depositing money and withdrawing money, the system can be split into two modules, one module is only responsible for the function of depositing money, and the other module is only responsible for the function of withdrawing money. Although it is an application system, it does not interfere with each other. After splitting into modules, each module needs to send a class loading request to the class loader, and the class loader loads the class file into binary data into memory and plac...
