1、编译agent代码
javac -encoding UTF-8 com/example/agent/SimpleAgent.java

// 如果不加-encoding UTF-8可能会报如下错误
src\org\example\MyAgent.java:18: 错误: 编码 GBK 的不可映射字符 (0xB0)
            // 鎵撳嵃姝ｅ湪鍔犺浇鐨勭被鐨勫悕绉?
                               ^
1 个错误

2、编写MANIFEST.MF文件
3、使用jar命令将编译后的类和MANIFEST.MF文件打包成JAR文件
jar cmf MANIFEST.MF SimpleAgent.jar com/example/agent

4、运行带有Agent的Java程序
javac com/example/app/SimpleApp.java
java -javaagent:SimpleAgent.jar=includes=* -cp . com/example/app/SimpleApp
```

添加agent：
-javaagent:D:\MyProjects\java-agent\bytebuddy-agent\target\bytebuddy-agent-1.0-SNAPSHOT-jar-with-dependencies.jar
带参数：
-javaagent:/path/to/agent.jar=dbUrl=jdbc:mysql://localhost:3306/test,username=root,password=123456
