修改反编译插件的源码

修改反编译程序

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;


import javassist.*;
import javassist.CtField.Initializer;

public class Js {
    public static void main(String[] args) throws Exception{
        ClassPool cp = ClassPool.getDefault();
        CtClass javaUtils = cp.get("com.seventh7.mybatis.util.JavaUtils");
        //System.out.println("cc == " + cc);
        CtMethod refValid =  javaUtils.getDeclaredMethod("refValid");
        System.out.println("method == " + refValid);
        refValid.setBody("{validated = true; valid = true; return valid;}");
        javaUtils.writeFile("ok\\class");




        CtClass javaService = cp.get("com.seventh7.mybatis.service.JavaService");
        CtMethod stop = javaService.getDeclaredMethod("stop");
        stop.setBody("{return;}");
        javaService.writeFile("ok\\class");


    }
}

1.新建一个maven项目，增加pom.xml依赖文件

<dependencies>
    <!-- https://mvnrepository.com/artifact/org.javassist/javassist -->
    <dependency>
        <groupId>org.javassist</groupId>
        <artifactId>javassist</artifactId>
        <version>3.21.0-GA</version>
    </dependency>
</dependencies>

2.从inteilje默认路径C:\Users\Administrator\.IntelliJIdea2016.2\config\plugins\mybatis_plus\lib下拷贝jar包到新项目中

3. run上述程序，生产修改后的.class文件

4.拷贝上述生产的文件，并覆盖jar包本身的文件，即可
