Java代码反编译与混淆：原理、实践与保护策略

1. Java代码反编译

1.1 反编译测试示例

我们以 MessageInfoComplex 类为例，来测试反编译器的效果。 MessageInfoComplex 类是 MessageInfo 类的增强版本，用于在聊天应用中向远程主机发送消息文本和属性。以下是 MessageInfoComplex.java 的源代码：

package covertjava.decompile;
/**
* MessageInfo is used to send additional information with each message across
* the network. Currently it contains the name of the host that the message
* originated from and the name of the user who sent it.
*/
public class MessageInfoComplex implements java.io.Serializable {
    String hostName;
    String userName;
    public MessageInfoComplex(String hostName, String userName) {
        this.hostName = hostName;
        this.userName
