Spring Security-用户密码自定义加密

public class SunPasswordEncoder implements PasswordEncoder{

//@实现加密的方法，既将明文转换为密文的方法
 public String encodePassword(String rawPass, Object salt)
   throws DataAccessException {
  String pass = null;
  try {
   pass = Tools.encryptBasedDes(rawPass);
  } catch (Exception e) {
   e.printStackTrace();
  }
  return pass;
 }

 //@验证密码是否有效的方法，返回'true'则登录成功

 public boolean isPasswordValid(String encPass, String rawPass, Object salt)
   throws DataAccessException {
  
  String pass1 = "" + encPass;
  String pass2 = encodePassword(rawPass, salt);
  return pass1.equals(pass2);
 }

<bean id="myEncoder" class="com.xxx.common.SunPasswordEncoder" />

 <sec:authentication-provider user-service-ref="xxxxxxServiceImpl">
  <!-- sec:password-encoder hash="md5" / -->
