    • The present disclosure discloses a protecting method and system of Java source code. When a first initiating class is invoked, the method comprises following steps, wherein the first initiating class is an initiating class of Java program: the first initiating class decrypts first cipher data to obtain a class loader; the class loader reads second cipher data to the memory and decrypts the second cipher data to obtain a first class, wherein the first class is a class run by a Java virtual machine, and the suffix of the first class is .class; the class loader loads a second initiating class to the memory; wherein the second initiating class is an original class in jar packet of the Java program; and the class loader loads the first class to the Java virtual machine so that the Java virtual machine can invoke a main interface in the second initiating class to run the Java program. The present disclosure can protect Java source code and make it difficult to decompile the Java source code.
    • 本公开公开了一种Java源代码的保护方法和系统。 当调用第一起始类时,该方法包括以下步骤,其中第一起始类是Java程序的发起类:第一起始类解密第一密码数据以获得类加载器; 类加载器将第二密码数据读取到存储器并解密第二密码数据以获得第一类,其中第一类是由Java虚拟机运行的类,第一类的后缀是.class; 类加载器将第二个启动类加载到内存中; 其中第二起始类是Java程序的jar包中的原始类; 并且类加载器将第一个类加载到Java虚拟机,以便Java虚拟机可以调用第二个启动类中的主界面来运行Java程序。 本公开可以保护Java源代码并且使得难以反编译Java源代码。
