14 集合項目

1，目錄結構如下

2，新建一個springcloud-2.0-parent項目
導入jar

        </repository>
    </repositories>

</project>

3,新建model springcloud-2.0-api-service
4,在model裏新建 springcloud-2.0-api-member-service , springcloud-2.0-api-order-service
5在 springcloud-2.0-api-member-service 裏面新建entity, service包 ，分別建立2個class

package com.taotao.demo.entity;


public class UserEntity {
    private  String name;
    private  Integer age;

    public String getName() {
        return name;
    }

    public UserEntity setName(String name) {
        this.name = name;
        return this;
    }

    public Integer getAge() {
        return age;
    }

    public UserEntity setAge(Integer age) {
        this.age = age;
        return this;
    }
}

package com.taotao.demo.service;

import com.taotao.demo.entity.UserEntity;
import org.springframework.web.bind.annotation.RequestMapping;


public interface IMemberService {
    //實體類是存放接口項目還是存放在實現項目裏
    //實體類和定義接口信息存放在接口項目
    //代碼實現存放在接口實現項目裏
@RequestMapping("/getMember")
public UserEntity getMember(String name);


}

6,在springcloud-2.0-parent 新建2個項目，

springcloud-2.0-api-member-service-impl , springcloud-2.0-api-order-service-impl

7， springcloud-2.0-api-member-service-impl 的jar包
pom.xml

            <url>https://repo.spring.io/milestone</url>
        </repository>
    </repositories>

</project>

4,啓動類

package com.taotao.demo;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.openfeign.EnableFeignClients;


@EnableEurekaClient
@EnableFeignClients
@SpringBootApplication
public class DemoApplication {

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

}

新建 com.taotao.demo.service.impl 包

package com.taotao.demo.service.impl;

import com.taotao.demo.entity.UserEntity;
import com.taotao.demo.service.IMemberService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MemberServiceImpl  implements IMemberService {
    @Override
    @RequestMapping("/getMember")
    public UserEntity getMember(String name) {
        UserEntity userEntity =new UserEntity();
        userEntity.setName(name);
        userEntity.setAge(20);
          return userEntity;
    }
}
