spring secrity 自定义验证

sPRing secrity 验证默认是使用username和passWord。但是我项目的登录是根据用户的   的工号和密码进行验证的，所有 有点不同。

关键点是 自己实现了   myAuthenticationProvider;

这个是我实现的的  myAuthenticationProvider;

package com.threeti.danfoss.base.filter;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.security.authentication.AuthenticationProvider;import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;import org.springframework.security.core.Authentication;import org.springframework.security.core.AuthenticationException;import org.springframework.security.core.userdetails.UserDetails;import org.springframework.security.core.userdetails.UserDetailsService;import com.threeti.danfoss.base.exception.LoginLockException;import com.threeti.danfoss.base.repository.XaCmsUserRepository;import com.threeti.danfoss.base.util.MD5Util;public class MyAuthenticationProvider implements AuthenticationProvider{@AutowiredXaCmsUserRepository xaCmsUserRepository;private UserDetailsService userDetailsService;      public MyAuthenticationProvider(UserDetailsService userDetailsService) {          this.userDetailsService = userDetailsService;      }    public UserDetailsService getUserDetailsService() {return userDetailsService;}public void setUserDetailsService(UserDetailsService userDetailsService) {this.userDetailsService = userDetailsService;}@Overridepublic Authentication authenticate(Authentication authentication) throws AuthenticationException {UsernamePasswordAuthenticationToken token = (UsernamePasswordAuthenticationToken) authentication;          String username = token.getName();          //从数据库找到的用户          UserDetails userDetails = null;          if(username != null) {              userDetails = userDetailsService.loadUserByUsername(username);          }          //XaCmsUser user =xaCmsUserRepository.findByNumberAndPasswordAndStatus(userDetails.getUsername(),        //MD5Util.getMD5String(userDetails.getPassword()), XaConstant.UserStatus.status_normal);        if(userDetails == null) {        throw new LoginLockException("账号或者密码错误");         }        //数据库用户的密码          String password = userDetails.getPassword();          //与authentication里面的credentials相比较          if(!password.equals(MD5Util.getMD5String((String)token.getCredentials()))) {              //throw new BadCredentialsException("Invalid username/password");            throw new LoginLockException("账号或者密码错误");         }          //授权          return new UsernamePasswordAuthenticationToken(userDetails, password,userDetails.getAuthorities());  }@Overridepublic boolean supports(Class<?> authentication) {return UsernamePasswordAuthenticationToken.class.equals(authentication); }}

我标红色的部分就是关键，在MyAuthenticationProvider  中注入了 UserDetailsService 

，调用了loadUserByUsername(username)方法

package com.threeti.danfoss.base.security;import java.util.ArrayList;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.security.core.GrantedAuthority;import org.springframework.security.core.authority.SimpleGrantedAuthority;import org.springframework.security.core.userdetails.UserDetails;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.security.core.userdetails.UsernameNotFoundException;import org.springframework.stereotype.Service;import com.threeti.danfoss.base.constant.XaConstant;import com.threeti.danfoss.base.entity.XaCmsUser;import com.threeti.danfoss.base.exception.LoginLockException;import com.threeti.danfoss.base.repository.XaCmsUserRepository;import com.threeti.danfoss.base.util.DateProcessUtil;/** * 登录权限验证service * @author zj * */@Service("MsUserDetailsService")public class XaUserDetailsService implements UserDetailsService {    protected static final String ROLE_PREFIX = "ROLE_";    protected static final GrantedAuthority DEFAULT_USER_ROLE = new SimpleGrantedAuthority(ROLE_PREFIX + "USER");@AutowiredXaCmsUserRepository xaCmsUserRepository;public UserDetails loadUserByUsername(String username)throws UsernameNotFoundException {XaUserDetails msUserDetails = new XaUserDetails();try {XaCmsUser user;//List<XaCmsUser> userList = xaCmsUserRepository.findByUserName(new String(username.getBytes("ISO-8859-1"),"UTF-8"));

// 这里也是关键，注意，我这里是通过工号进行查询的List<XaCmsUser> userList = xaCmsUserRepository.findByNumber(new String(username.getBytes("ISO-8859-1"),"UTF-8"));if(userList.size() > 0 && userList.get(0).getStatus() == XaConstant.UserStatus.status_lock){throw new LoginLockException("您输入的账号已被锁定");}/*if(userList.size() > 0 && userList.get(0).getIsAdmin() != 1){throw new LoginAdminException("您的账号不是管理员");}*/if(userList.size() > 0 && userList.get(0) != null){user = userList.get(0);user.setLastLoginDate(DateProcessUtil.getToday(DateProcessUtil.YYYYMMDDHHMMSS));xaCmsUserRepository.save(user);msUserDetails.setUsername(user.getNumber());msUserDetails.setPassword(user.getPassword());List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();GrantedAuthority authority = new SimpleGrantedAuthority(user.getRole().getRoleName());authorities.add(authority);//设置用户oauth通过token访问的权限authorities.add(DEFAULT_USER_ROLE);authorities.add(new SimpleGrantedAuthority(ROLE_PREFIX + "UNITY"));authorities.add(new SimpleGrantedAuthority(ROLE_PREFIX + "MOBILE"));msUserDetails.setAuthorities(authorities);//msUserDetails.setToken(TokenCenter.issueToken(user.getUserId()));}} catch (Exception e) {e.printStackTrace();}return msUserDetails;}}
