2 springCloud 创建两个微服务

先总结：需要引入父依赖，然后加上spring-boot-starter-web 就可以直接启动了

创建两个子模块微服务（demo1,demo2） 作为生产者和消费者，留着后面使用

demo1

修改pom 把父依赖的坐标粘过来

 <parent>
        <groupId>com.kjgs</groupId>
        <artifactId>springclouddemo2</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>

并把下面这块删掉，没有了，都沿用父依赖的配置

在加入如下配置

  <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

总的pom如下：

<?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"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.kjgs</groupId>
        <artifactId>springclouddemo2</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <groupId>com.kjgs</groupId>
    <artifactId>demo1</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>demo1</name>
    <description>Demo project for Spring Boot</description>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

添加application.yml文件

配置如下:

server:
  port: 8280
  servlet:
    context-path: /demo1

spring:
  application:
    name: demo1

再加个controller 测试接口

package com.kjgs.demo1.controller;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashMap;
import java.util.Map;

@RestController
public class HealthController {
    
    @RequestMapping("/getHealth")

    public Map getHealth(){
        Map map = new HashMap();
        map.put("123","2sdf");
        return map;
    }
    
}

启动，测试

启动成功，接口正常

同理 再建个demo2

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

</project>

server:
  port: 8281

spring:
  application:
    name: demo2
eureka:
  client:
    service-url:
     defaultZone: http://localhost:8283/eureka/
