1.springboot服务注册
1.1创建注册中心
1）在idea中选择File-New-Project-Spring Initializr，界面选择SDK等
2）点击Next，设置Group等，这里选择的java的版本是8
3）点击Next，选择Spring Cloud Discovery，并在右侧选择Eureka Server
4）设置Projectname既可完成
1.2 spring的代码及配置
1）Appilcation:
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@EnableEurekaServer
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
2)pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

需要注意springboot和springcloud的版本对应关系，否则可能由于不匹配导致报错
3）application.yml
server:
port: 1111
spring:
application:
name: enreka-server
eureka:
instance:
hostname: localhost
client:
register-with-eureka: false
fetch-registry: false
service-url:
defaultZone: http://172.17.6.74:1111/eureka/ #给客户端用的,注意这里结束必须是eureka
4）此时启动之后，在网页中输入http://localhost:1111，会显示：
1.2创建客户端
1）新建项目与服务的区别在于选择Spring Cloud Discovery中选择Eureka Discovery Client
2）application
package com.springcloud.demoprovider;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
@EnableEurekaClient
@SpringBootApplication
public class DemoproviderApplication {
public static void main(String[] args) {
SpringApplication.run(DemoproviderApplication.class, args);
}
}
3）application.yml
server:
port: 1112
spring:
application:
name: demoprovider
eureka:
client:
service-url:
defaultZone: http://172.17.6.74:1111/eureka/
fetch-registry: true
register-with-eureka: true
4)service
package com.springcloud.service;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.management.ValueExp;
@RestController
public class DemoService {
@GetMapping(value="/login")
public void login(){
System.out.println( "provider 被调用了");
}
}
4)启动之后，可以在注册中心看到该服务
以上是可以注册的，但是无法真正的访问到我的接口，这里是因为接口的package存放地方有问题，详细可见：https://www.freesion.com/article/1174657845/

2.编译问题
编译时可以设置跳过test，可以使用mvn的命令，也可以在项目中不将test识别为测试目录（这个最简单），设置方法：选中test->右键选中Mark Directory as ->Unmark as test source root
