Spring Boot+Spring Security+MySql实现用户权限管理(3)

具体Demo

具体Demo目录：

实体类

User类为认证和授权实体类，
Role类为用户角色类，有ROLE_ADMIN和ROLE_USER
User:

package com.example.demo.entity;

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

import javax.persistence.*;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
