Abstract

The invention discloses a method for detecting JAR packet collision. The method comprises the following steps: selecting a JAR packet which is about to undergo collision detection; in allusion to each class in the JAR packet, analyzing a bytecode file corresponding to the class, checking whether a bytecode file corresponding to a class depending on the class exists in a pre-assigned JAR packet list and checking whether elements accessed by the class exist in the bytecode file related to the depended class; and if any check result is negative, considering that the current JAR packet has collision. The invention furthermore provides a device for detecting JAR packet collision. By adopting the method provided by the invention, the collision of the JAR packet in the aspect of dependency completeness can be automatically detected, so that a foundation is provided for eliminating the collision through previously adopting a JAR packet updating manner and the like, and the fault caused by the deficiency of dependency completeness in the running stage can be effectively avoided.

Description

technical field [0001] This application relates to the field of Java application development, in particular to a method for detecting JAR package conflicts. The present application also provides a device for detecting JAR package conflicts. Background technique [0002] Java is an object-oriented programming language that can write cross-platform application software. It is the general term for the Java programming language and Java platform (ie JavaEE, JavaME, JavaSE) launched by Sun Microsystems in May 1995. Using the Java language for application development, first write the source code with the file suffix .java, and then compile the source code into a machine-independent binary bytecode (bytecode) through a compiler, namely: .class file, run When relying on the virtual machines (JVM) of various platforms to find and load the class to be executed in the pre-set class loading path, and interpret and execute the bytecode program, so as to realize the cross-platform featur...
