Spring Security 自定义登录验证与自定义回调地址
1 配置文件 security-ns.xml
//需要过滤不被拦截的请求
//密码加密工具类
//UserDetailsService实现 主要用于用户的查询
//成功登录后
//登录失败
2 UserLoginServiceImpl 查询用户实现类
@Named("userLoginService")
public class UserLoginServiceImpl implements UserDetailsService ,LoginService{
@Inject
private UserLoginDAO userLoginDAO;
@Override
public WrappedUserLogin getUserLogin() {
try {
WrappedUserLogin wrappedUserLogin = (WrappedUserLogin) SecurityContextHolder
.getContext().getAuthentication().getPrincipal();
return wrappedUserLogin;
} catch (Exception e) {
return null;
}
}
@Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException {
System.out.println("用户名-------------"+username);
UserLogin userLogin = null;
if(username != null && !"".equals(username)&& username.indexOf("@") > 0){
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 resultAuths = new ArrayList();
// 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{
//用户名
public static final String SPRING_SECURITY_FORM_USERNAME_KEY = "j_username";
//密码
public static final String SPRING_SECURITY_FORM_PASSWORD_KEY = "j_password";
//需要回调的URL 自定义参数

*/

}

}
//自定义回调URL，若存在则放入Session
if(redirectUrl != null && !"".equals(redirectUrl)){
request.getSession().setAttribute("callCustomRediretUrl", redirectUrl);
}
username = username.trim();
UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password);
// Allow subclasses to set the "details" property
setDetails(request, authRequest);
return this.getAuthenticationManager().authenticate(authRequest);
}
/**
