2.1 登录界面
http://localhost:8082/ 或者 http://localhost:8082/login
登录页面代码:

2.2 登录认证
UserServiceImpl 中修改 query 方法
@Override
public List<User> query(User user) {
UserExample example = new UserExample();
if(user!=null){
if(!"".equals(user.getUserName()) && user.getUserName()!= null){
// 根据账号查询
example.createCriteria().andUserNameEqualTo(user.getUserName());
}
}
return userMapper.selectByExample(example);
}
自定义 Realm 中完成认证的逻辑
@Resource
private IUserService userService;
/**
认证的方法
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
// 获取提交的账号
UsernamePasswordToken t = (UsernamePasswordToken) token;
// 获取登录的账号
String userName = t.getUsername();
User user = new User();
user.setUserName(userName);
List<User> list = userService.query(user);
if(list == null || list.size() > 1){
// 账号不存在或者用户过多都返回 null
return null;
}
user = list.get(0);
SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, user.getPassword(),"bobo");
return info;
}
完成 controller 逻辑
@Controller
public class LoginController {
/**
设定登录失败跳转的资源以及获取失败的信息
@param model
@param request
@return
*/
@RequestMapping("/login.do")
public String login(Model model, HttpServletRequest request) {
Object ex = request.getAttribute(FormAuthenticationFilter.DEFAULT_ERROR_KEY_ATTRIBUTE_NAME);
if (ex != null) {
System.out.println(ex.toString() + "----------");
}
if (UnknownAccountException.class.getName().equals(ex)) {
System.out.println("----账号不正确----->");
model.addAttribute("msg", "账号不正确");
} else if (IncorrectCredentialsException.class.getName().equals(ex)) {
System.out.println("----密码不正确----->");
model.addAttribute("msg", "密码不正确");
} else {
System.out.println("----其他错误----->");
model.addAttribute("msg", "其他错误");
}
return "login";
}
}
启动后随便输入一个地址，会发现重新跳回了登录页面
