认证类：
package com.pinyougou.user.service;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;

public class UserDetailServiceImpl implements UserDetailsService {

@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
System.out.println("经过认证类:"+username);

List<GrantedAuthority> authorities=new ArrayList();
authorities.add(new SimpleGrantedAuthority("ROLE_USER"));

return new User(username,"",authorities);
}

}

现在就是单点登录 登录成功后 不跳转指定URL。
自己访问项目路径，又重新回到单点登录页面，登录成功后还是不跳转
