security验证账号密码后不能跳转到页面

使用spring security框架设置配置类验证账号密码后跳转白页

配置类代码如下

package com.l.securitydemo1.service;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
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;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("userDetailsService")//将本类注入到spring容器中，并标明本类为service类，在其他类中直接创建注解中的同名对象即可使用本类
public class MyUserDetailService implements UserDetailsService {
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        List auths= AuthorityUtils.commaSeparatedStringToAuthorityList("roles");//用户权限集合，commaSeparatedStringToAuthorityList（分隔字符串到权限列表），
        return new User("www",new BCryptPasswordEncoder().encode("123"),auths);//返回用户名，密码，权限，在user对象汇总权限不能为null
    }
}

页面报错内容

你这块代码也没有调整呀
