需要解决分布式事务的问题 准备搭建一个服务的注册中心

pom文件引入

然后只需要在启动类中 添加注释@EnableEurekaServer
这样就把当前的服务 作为注册中心了
然后再通过application.yml进行 配置一些简单的配置

server:
  port: 8761

spring:
  application:
    name: registry
  security:
    user:
      name: zhou
      password: 12345678

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://localhost:${server.port}/eureka/

需要注意的是 springboot2.x之后 好像不支持security.user.name 这样方式来进行自定义了
需要使用
spring.security.user.name这样的方式来进行初始化了
然后启动项目

Eureka登录界面

• 使用初始化的用户名和密码登陆

然后配置Client pom文件如下

            </plugin>
        </plugins>
    </build>

</project>

然后启动类 添加@EnableZuulProxy,@EnableEurekaClient
配置文件如下

server:
  port: 8888

spring:
  application:
    name: proxy

eureka:
  client:
    serviceUrl:
      defaultZone: http://zhou:12345678@localhost:8761/eureka/

然后启动 出现报错

com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

现在找不到server 但是项目正在启动 配置文件 也没问题
发现是security 在springboot2.x之后 默认为csrf检验
在server端给关闭就可以了
新建一个config配置文件

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception{
        httpSecurity.csrf().disable();
        super.configure(httpSecurity);
    }
}

重新启动
