class2srcDecompiler

方法源自：https://stackoverflow.com/questions/272535/how-do-i-decompile-java-class-files

 

功能：给定一个.class文件，得到反编译的源码。

 

下载后导入工具包：Procyon （https://bitbucket.org/mstrobel/procyon/wiki/Java%20Decompiler）

 

Demo：

 
package util;

import java.io.StringWriter;

public class Decompile {

	public void main(String[] args) {
		String classPath = “*.class”; //input path of .class file
		String src = class2src(classPath);
		System.out.println(src);
	}

	public String class2src(String classPath) {
		final StringWriter writer = new StringWriter();
		String src = "";
		try {
			com.strobel.decompiler.Decompiler.decompile(classPath, new com.strobel.decompiler.PlainTextOutput(writer));
		} catch (IllegalArgumentException e) {
			System.out.println("classpath : " + classPath);
		} finally {
			src = writer.toString();
		}
		return src;
	}
}
