2 UserLoginServiceImpl 查询用户实现类
@Named("userLoginService")

@Override

WrappedUserLogin wrappedUserLogin = (WrappedUserLogin) SecurityContextHolder
.getContext().getAuthentication().getPrincipal();

userLogin = userLoginDAO.findByEmail(username);
username = userLogin.getNick();
}else{
userLogin = userLoginDAO.findByNick(username);
}
System.out.println("user is null ---"+userLogin.getUserType());
String nick = userLogin.getNick();
String email = userLogin.getEmail();
String mobile = userLogin.getMobile();
int userType = userLogin.getUserType();
List<GrantedAuthority> resultAuths = new ArrayList<GrantedAuthority>();
// 前台用户
if (userType == 1) {
resultAuths.add(new SimpleGrantedAuthority("ROLE_USER"));
} else {
resultAuths.add(new SimpleGrantedAuthority("ROLE_BACK_USER"));
}
return new WrappedUserLogin(userLogin.getId(), email, nick, mobile, userLogin.getPassword(), userType,resultAuths);
}
}
3 重写用户名密码验证
public class MyUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter{

//密码
public static final String SPRING_SECURITY_FORM_PASSWORD_KEY = "j_password";

4 SimpleUrlAuthenticationSuccessHandler重写

super.setDefaultTargetUrl(url);

}
//重设置默认URL为主页地址

return;
}
//targetUrlParameter 是否存在

5 认证失败控制类重写

* the destination instead of a redirect.
