sPRing secrity 驗證默認是使用username和passWord。但是我項目的登錄是根據用戶的   的工號和密碼進行驗證的，所有 有點不同。

關鍵點是 自己實現了   myAuthenticationProvider;

這個是我實現的的  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();          //從數據庫找到的用戶          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("賬號或者密碼錯誤");         }        //數據庫用戶的密碼          String password = userDetails.getPassword();          //與authentication里面的credentials相比較          if(!password.equals(MD5Util.getMD5String((String)token.getCredentials()))) {              //throw new BadCredentialsException("Invalid username/password");            throw new LoginLockException("賬號或者密碼錯誤");         }          //授權          return new UsernamePasswordAuthenticationToken(userDetails, password,userDetails.getAuthorities());  }@Overridepublic boolean supports(Class<?> authentication) {return UsernamePasswordAuthenticationToken.class.equals(authentication); }}

我標紅色的部分就是關鍵，在MyAuthenticationProvider  中注入了 UserDetailsService 

，調用了loadUserByUsername(username)方法

// 這里也是關鍵，注意，我這里是通過工號進行查詢的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("您輸入的賬號已被鎖定");}/*if(userList.size() > 0 && userList.get(0).getIsAdmin() != 1){throw new LoginAdminException("您的賬號不是管理員");}*/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);//設置用戶oauth通過token訪問的權限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;}}
