总体分为SpringSecurityOauth2授权码模式演示和密码模式演示

一直下一步,依赖手动导入,SpringBoot版本改成2.2.5.RELEASE,JDK版本1.8

授权码模式演示:

SpringSecurity引入之后会有一个默认用户user和默认密码,项目启动后控制台输出的那个

需要先自定义一个SpringSecurity登录逻辑,然后去修改用户密码

自定义SpringSecurity登录逻辑需要用到PasswordEncode对密码进行单向加密

如果想用自己自定义可以这么干

package com.example.springsecurityoauth2demo.pojo;

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

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

/**
 * @author hrui
 * @date 2023/1/16 8:47
 */
public class User implements UserDetails {
    private String username;
    private String password;
    private List<GrantedAuthority> authorities;

    public User(String username, String password, List<GrantedAuthority> authorities) {
        this.username = username;
        this.password = password;
        this.authorities = authorities;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return authorities;
    }

    @Override
    public String getPassword() {
        return password;
    }

    @Override
    public String getUsername() {
        return username;
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }
}

那么引入自定义的User就可以了
