本文目的：使用sPRingBoot＋springSecurity 用戶授權(quán)驗(yàn)證權(quán)限功能，對(duì)用戶的登錄密碼使用md5 加密。

本文基于我的博客：springboot+mybatis＋SpringSecurity 實(shí)現(xiàn)用戶角色數(shù)據(jù)庫(kù)管理 進(jìn)行修改。

本文只講述對(duì)密碼加密部分。只需要修改securityConfig 文件，并添加md5 工具類即可。

修改WebSecurityConfig.java

對(duì)于WebSecurityConfig.java 文件只需修改configure(AuthenticationManagerBuilder auth) 方法。

@Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(customUserService()).passWordEncoder(new PasswordEncoder(){ @Override public String encode(CharSequence rawPassword) { return MD5Util.encode((String)rawPassword); } @Override public boolean matches(CharSequence rawPassword, String encodedPassword) { return encodedPassword.equals(MD5Util.encode((String)rawPassword)); }}); //user Details Service驗(yàn)證 }

添加MD5工具類

package com.us.example.util;/** * Created by yangyibo on 17/2/7. */import java.security.MessageDigest;/** * MD5加密工具 * */public class MD5Util { private static final String SALT = "tamboo"; public static String encode(String password) { password = password + SALT; MessageDigest md5 = null; try { md5 = MessageDigest.getInstance("MD5"); } catch (Exception e) { throw new RuntimeException(e); } char[] charArray = password.toCharArray(); byte[] byteArray = new byte[charArray.length]; for (int i = 0; i < charArray.length; i++) byteArray[i] = (byte) charArray[i]; byte[] md5Bytes = md5.digest(byteArray); StringBuffer hexValue = new StringBuffer(); for (int i = 0; i < md5Bytes.length; i++) { int val = ((int) md5Bytes[i]) & 0xff; if (val < 16) { hexValue.append("0"); } hexValue.append(Integer.toHexString(val)); } return hexValue.toString(); } public static void main(String[] args) { System.out.println(MD5Util.encode("abel")); }}
