spring security 加密

 

package com.tht.md5;

import org.springframework.security.providers.encoding.Md5PasswordEncoder;

public class THTMD5PasswordEncoder {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		Md5PasswordEncoder md5=new Md5PasswordEncoder();

		/*
		 * "a" 是key
		 * "abc"  密码
