SpringBoot SSO輕鬆實現

提示:若有疑問請私信聯繫、下方有源代碼地址,請自行拿取java


前言

網上SSO的框架不少,此篇文章使用的是自寫的SSO來實現簡單的登陸受權功能,目的在於擴展性,權限這方面,自寫擴展性會好點。git


提示:如下是本篇文章正文內容,下面案例可供參考web

1、技術介紹

1.SSO是什麼?

單點登陸(SingleSignOn,SSO),就是經過用戶的一次性鑑別登陸。當用戶在身份認證服務器上登陸一次之後,便可得到訪問單點登陸系統中其餘關聯繫統和應用軟件的權限,同時這種實現是不須要管理員對用戶的登陸狀態或其餘信息進行修改的,這意味着在多個應用系統中,用戶只需一次登陸就能夠訪問全部相互信任的應用系統。這種方式減小了由登陸產生的時間消耗,輔助了用戶管理,是目前比較流行的。

2、使用步驟

1.引入maven庫

代碼以下(示例):redis

<parent>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-parent</artifactId>
          <version>2.4.1</version>
          <relativePath/>
	   </parent>
     <dependencies>
       <dependencies>
        <dependency>
            <artifactId>hyh-boot-starter-redis</artifactId>
            <groupId>com.hyh.redis</groupId>
            <version>1.0.0</version>
        </dependency>
    </dependencies>

2.具體使用示例

public interface ILogin {

    /** * 登陸 * * @param account 用戶名 * @param password 密碼 * @param callbackUrl 用戶驗證回調URL * @return */

登陸狀態枚舉:json

    private int code;

    private String message;


    private LoginStatus(int code, String message) {
        this.code = code;
        this.message = message;
    }


    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
