摘　　要：Java编程语言被大量的工程项目使用,对Java源代码进行保护,防止其被窃取和篡改是非常有必要的。该文以Open-JDK和Oracle JDK的编译器Javac为基础,以编译器插件的形式设计和实现了一个作用于Java源代码的混淆器。该混淆器通过修改由编译器提供的抽象语法树和实现访问者模式达到混淆源代码的目的。该文介绍了名称变换、包修改和数组下标同态计算三种混淆方法。同时,该混淆器被包装成Maven插件,以方便实际项目的使用。The Java programming language is used by many engineering projects and it is necessary to protect the Java source code against theft and tampering. Based on compiler Javac of OpenJDK and Oracle JDK, this paper designs and implements an obfusca- tor that acts on Java source code in the form of compiler plug-in. The obfuscator achieves the purpose of obfuscating the source code by modifying the abstract syntax tree provided by the compiler and implementing the visitor pattern. This article introduces the three obfuscation methods of name conversion, package modification, and array index homomorphic calculation. Meanwhile, the obfuscator is packaged as a Maven plugin to facilitate the use of actual projects.
