Spring Cloud 单点登录 详解基于Spring Cloud几行配置完成单点登录开发
冷冷gg 人气:0想了解详解基于Spring Cloud几行配置完成单点登录开发的相关内容吗，冷冷gg在本文为您仔细讲解Spring Cloud 单点登录的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：Spring,Cloud,单点登录，下面大家一起来学习吧。
单点登录概念
单点登录（Single Sign On），简称为 SSO，是目前比较流行的企业业务整合的解决方案之一。SSO的定义是在多个应用系统中，用户只需要登录一次就可以访问所有相互信任的应用系统。登录逻辑如上图
基于Spring 全家桶的实现
技术选型：
- Spring Boot
- Spring Cloud
- Spring Security oAuth2
客户端：
maven依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.security.oauth</groupId> <artifactId>spring-security-oauth2</artifactId> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-jwt</artifactId> </dependency>
EnableOAuth2Sso 注解
入口类配置@@EnableOAuth2Sso
@SpringBootApplication
public class PigSsoClientDemoApplication {
public static void main(String[] args) {
SpringApplication.run(PigSsoClientDemoApplication.class, args);
}
}
