Second, the project structure Introduction

Third, the integration start
1. Create springboot-dubbo-paren parent project (POM)
1, created after the completion of the src directory delete

2, pom-dependent parent project as follows:

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">

2, create springboot-dubbo-public-api- service public Api Interface project (pom)
Note : sub-projects under the parent project engineering (springboot-dubbo-paren) ( Module)

1. Once created deleted src directory

2, the interface of public works Api pom-dependent as follows:

1, Member Services Interface Engineering pom-dependent as follows:

com.slming.api.memeber Package;

/ **
* @author itslm
* /
public interface IMemberService {

/ **
* Get Member
* a
* the Author: Leiming She 
* a Date : 2019-04-29 10:05:36 
*
* @param username username
* @return java.lang.String
* /
String GetMember (String username);
}
. 4, creating springboot-dubbo-api-member -service-impl Member realization of the project (jar)
Note: the sub-project (Module) under the parent project engineering (springboot-dubbo-paren)

1, Member Services pom-dependent realization of the project are as follows:

Note: This class is @Service notes for the next com.alibaba.dubbo.config.annotation.Service package, do not guide the wrong bag oh ~

package com.slming.api.memeber.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.slming.api.memeber.IMemberService;

/**
* @author itslm
*/
@Service
public class MemberServiceImpl implements IMemberService {

/**
* 获取会员
* 
* Author: Leiming She
* Date: 2019-04-29 10:05:36
*
* @param username 用户名
* @return java.lang.String
*/
@Override
public String getMember(String username) {
return "Dubbo：" + username;
}
}
3、创建application.yml文件：

Server:
Port: 8080
Dubbo:
the Application:
name: Member
Protocol:
Port: 20880
name: Dubbo
Registry:
address: ZooKeeper: //127.0.0.1: 2181
4, to create applications startup class: com.slming.AppMemberApplication

Note: @EnableDubbo need to add annotations, support for open Dubbo

com.slming Package;

Import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
Import org.springframework.boot.SpringApplication;
Import org.springframework.boot.autoconfigure.SpringBootApplication;

/ **
* @author itslm
* /
@SpringBootApplication
@EnableDubbo
public class AppMemberApplication {

public static void main (String [] args) {
SpringApplication.run (AppMemberApplication.class, args);
}
}
. 5, creating springboot-dubbo-order-web line Engineering (JAR)
Note: sub-project (Module) under the parent project engineering (springboot-dubbo-paren)

1, pom-dependent engineering orders as follows:

Note: no longer used here @Autoware be injected,

Injection was used in com.alibaba.dubbo.config.annotation.Reference packet @Reference

package com.slming.order.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.slming.api.memeber.IMemberService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

/**
* @author itslm
*/
@RestController
public class OrderController {

@Reference
private IMemberService memberService;

@GetMapping("getMember/{username}")
public String getMember(@PathVariable("username") String username){
return memberService.getMember(username);
}
}
3. Create application.yml file:

Server:
Port: 8082
Dubbo:
the Application:
name: the Order
Registry:
address: ZooKeeper: //127.0.0.1: 2181
Consumer:
timeout: 5000
4, to create applications startup class: com.slming.AppOrderApplication

Note: @EnableDubbo need to add annotations, support for open Dubbo

package com.slming;

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
* @author itslm
*/
@EnableDubbo
@SpringBootApplication
public class AppOrderApplication {

public static void main(String[] args) {
SpringApplication.run(AppOrderApplication.class, args);
}
}
四、启动项目
1、启动zookeeper注册中心

2, start the service members achieve the project (springboot-dubbo-api-member-service-impl)

3, the start order item (springboot-dubbo-order-web)

4, point your browser to: localhost: 8082 / getMember / itslm enter, if that is the following page shows the successful integration!

V. pack
1, the install can be directly in the parent project

2, if the package is successful, the bottom of the console will output the following information:

Since the output more information, on top of the information omitted here ...... just posted a lowermost output.

[INFO] ----------------------------------------------- -------------------------
[the INFO] the Reactor the Summary:

[INFO] Finished at: 2019-04-30T15:23:35+08:00
[INFO] ------------------------------------------------------------------------

Process finished with exit code 0
3、查看jar包

At this time, members of the project realization (springboot-dubbo-api-member-service-impl) and order item (springboot-dubbo-order-web) will be more target directory under the directory, there are packaged inside the jar package, They are as follows:

springboot-dubbo-api-member-service-impl-1.0-SNAPSHOT.jar

springboot-dubbo-order-web-1.0-SNAPSHOT.jar

4, run the jar package:

Open a command line window in the directory where the jar package, push the order of execution (Note: The order can not be reversed, otherwise the visit will throw a 500 error)

-jar springboot-Dubbo-the Java API-Member-Service-impl-1.0-SNAPSHOT.jar

the Java -jar springboot-Dubbo-the Order-Web-1.0-SNAPSHOT.jar
