【springboot系列】springboot接入md5

springboot接入md5

一、依赖包

	<dependency>
	    <groupId>commons-codecgroupId>
	    <artifactId>commons-codecartifactId>
	dependency>
	<dependency>
	    <groupId>org.apache.commonsgroupId>
	    <artifactId>commons-lang3artifactId>
	    <version>3.6version>
	dependency>

二、md5工具类

两次md5，加salt的md5。

package xyz.haibofaith.miaosha.util;

import org.apache.commons.codec.digest.DigestUtils;

public class MD5Util {
	
	public static String md5(String src) {
		return DigestUtils.md5Hex(src);
	}
	
	private static final String salt = "1a2b3c4d";

	/**
	 * 第一次md5
	 * @param inputPass
	 * @return
	 */
	public static String inputPassToFormPass(String inputPass) {
		String str = ""+salt.charAt(0)+salt.charAt(2) + inputPass +salt.charAt(5) + salt.charAt(4);
		System.out.println(str);
		return md5(str);
	}

	/**
	 * 第二次md5
	 * @param formPass
	 * @param salt
	 * @return
	 */
	public static String formPassToDBPass(String formPass, String salt) {
		String str = ""+salt.charAt(0)+salt.charAt(2) + formPass +salt.charAt(5) + salt.charAt(4);
		return md5(str);
	}

	/**
	 * 两次md5
	 * @param inputPass
	 * @param saltDB
	 * @return
	 */
	public static String inputPassToDbPass(String inputPass, String saltDB) {
		String formPass = inputPassToFormPass(inputPass);
		String dbPass = formPassToDBPass(formPass, saltDB);
		return dbPass;
	}
	
	public static void main(String[] args) {
		System.out.println(inputPassToFormPass("123456"));//d3b1294a61a07da9b49b6e22b2cbd7f9
//		System.out.println(formPassToDBPass(inputPassToFormPass("123456"), "1a2b3c4d"));
		System.out.println(inputPassToDbPass("123456", "1a2b3c4d"));//b7797cce01b4b131b433b6acf4add449
	}
	
}

控制台输出结果：

12123456c3
d3b1294a61a07da9b49b6e22b2cbd7f9
12123456c3
b7797cce01b4b131b433b6acf4add449
Process finished with exit code 0

则一次加密结果是d3b1294a61a07da9b49b6e22b2cbd7f9
二次加密结果是b7797cce01b4b131b433b6acf4add449
