SimpleGrantedAuthority的替代方案

Question

我最近开始了一个springboot课程，其中课程主管使用Spring Security GrantedAuthority界面。我无法解决GrantedAuthority的路径。在阅读更多内容之后，我看到它已被删除，现在应该使用SimpleGrantedAuthority。出于某种原因，我也无法解析SimpleGrantedAuthority的路径。在security.core.authority下我只有Mapping。知道我可以使用什么吗？

The code of the course I started:

package com.bookstore.domain.security;

import java.io.Serializable;

import org.springframework.security.core.GrantedAuthority;

public class Authority implements GrantedAuthority, Serializable {
    private static final long serialVersionUID = 123123L;

    private final String authority;

    public Authority(String authority) {
        this.authority = authority;
    }

    @Override
    public String getAuthority() {
        return authority;
    }
}
