Spring Cloud OAuth2

二、​​Spring Cloud OAuth2 token存数据库实现​​​ 三、​​Spring Cloud Oauth2 JWT 实现​​

学习一下Spring Cloud OAuth2，我们分三个项目 eureka-server、service-auth、service-hi

1. 创建eureka-server项目

选择依赖 spring-cloud-starter-netflix-eureka-server

1.1 启动类里添加注释

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }
}

1.2 application.yml

spring:
  application:
    name: eureka-server
server:
  port: 8761
eureka:
  instance:
    hostname: localhost
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
    fetch-registry: false
    register-with-eureka: false

配置完成可以访问 ​​http://localhost:8761​​

2 创建service-auth项目

2.1 用于获取授权token，项目上目录结构：

这里有个有趣的地方，如果包名config和customImpl和启动类不在同一个根包下，会扫不到包，此时必须在启动类上增加 ​​@ComponentScan(basePackages = "包名")​​

2.2 创建项目依赖

• spring-boot-starter-data-redis把token存到redis中
• spring-cloud-starter-netflix-eureka-client做为EurekaClient
• spring-cloud-starter-oauth2是对spring-cloud-starter-security、spring-security-oauth2、spring-security-jwt这3个依赖的整合
• spring-boot-starter-actuator
