--------------------------------------------------------------------------------
  1 | # SpringBoot整合dubbo示例
  2 | ## 一、定义API（API模块）
  3 | ### 1. 定义api
  4 | ```java
  5 | package com.imooc.springboot.dubbo.demo;
  6 | 
  7 | public interface DemoService {
  8 |     String sayHello(String name);
  9 | }
 10 | ```
 11 | ### 2. install到本地
 12 | 对外提供的maven坐标如下：
 13 | ```xml
 14 | <dependency>
 15 |     <groupId>com.imooc</groupId>
 16 |     <artifactId>dubbo-demo-api</artifactId>
 17 |     <version>1.0-SNAPSHOT</version>
 18 | </dependency>
 19 | ```
 20 | ## 二、服务提供者（provider模块）
 21 | ### 1. 增加maven依赖
 22 | ```xml
 23 | <!-- springboot parent -->
 24 | <parent>
 25 |     <groupId>org.springframework.boot</groupId>
 26 |     <artifactId>spring-boot-starter-parent</artifactId>
 27 |     <version>1.5.3.RELEASE</version>
 28 | </parent>
 29 | <!-- springboot dubbo starter -->
 30 | <dependency>
 31 |     <groupId>io.dubbo.springboot</groupId>
 32 |     <artifactId>spring-boot-starter-dubbo</artifactId>
 33 |     <version>1.0.0</version>
 34 | </dependency>
 35 | <!-- api dependence -->
 36 | <dependency>
 37 |     <groupId>com.imooc</groupId>
 38 |     <artifactId>dubbo-demo-api</artifactId>
 39 |     <version>1.0-SNAPSHOT</version>
 40 | </dependency>
 41 | ```
 42 | ### 2. 实现API接口
 43 | ```java
 44 | package com.imooc.springboot.dubbo.demo.provider;
 45 | 
 46 | import com.alibaba.dubbo.config.annotation.Service;
 47 | import com.imooc.springboot.dubbo.demo.DemoService;
 48 | 
 49 | @Service
 50 | public class DemoServiceImpl implements DemoService {
 51 | 
 52 |     public String sayHello(String name) {
 53 |         return "Hello, " + name + " (from Spring Boot)";
 54 |     }
 55 | 
 56 | }
 57 | ```
 58 | ### 3. springboot配置文件 - application.properties
 59 | ```bash
 60 | spring.dubbo.application.name=demo-provider
 61 | #这里使用广播的注册方式，
 62 | #如果有Can't assign address异常需要加vm参数：
 63 | #-Djava.net.preferIPv4Stack=true
 64 | spring.dubbo.registry.address=multicast://224.5.6.7:1234
 65 | spring.dubbo.protocol.name=dubbo
 66 | spring.dubbo.protocol.port=20880
 67 | spring.dubbo.scan=com.imooc.springboot.dubbo.demo.provider
 68 | ```
 69 | 
 70 | ### 4. 启动类
 71 | ```java
 72 | package com.imooc.springboot.dubbo.demo.provider;
 73 | 
 74 | import org.springframework.boot.SpringApplication;
 75 | import org.springframework.boot.autoconfigure.SpringBootApplication;
 76 | 
 77 | @SpringBootApplication
 78 | public class MainProvider {
 79 |     public static void main(String[] args) {
 80 |         SpringApplication.run(MainProvider.class,args);
 81 |     }
 82 | }
 83 | ```
 84 | ## 三、服务消费者（consumer模块）
 85 | ### 1. 增加maven依赖
 86 | ```xml
 87 | <!-- springboot parent -->
 88 | <parent>
 89 |     <groupId>org.springframework.boot</groupId>
 90 |     <artifactId>spring-boot-starter-parent</artifactId>
 91 |     <version>1.5.3.RELEASE</version>
 92 | </parent>
 93 | <!-- springboot web starter -->
 94 | <dependency>
 95 |    <groupId>org.springframework.boot</groupId>
 96 |     <artifactId>spring-boot-starter-web</artifactId>
 97 | </dependency>
 98 | <!-- springboot dubbo starter -->
 99 | <dependency>
100 |     <groupId>io.dubbo.springboot</groupId>
101 |     <artifactId>spring-boot-starter-dubbo</artifactId>
102 |     <version>1.0.0</version>
103 | </dependency>
104 | <!-- api dependency -->
105 | <dependency>
106 |     <groupId>com.imooc</groupId>
107 |     <artifactId>dubbo-demo-api</artifactId>
108 |     <version>1.0-SNAPSHOT</version>
109 | </dependency>
110 | ```
111 | ### 2. 实现controller
112 | ```java
113 | package com.imooc.springboot.dubbo.demo.consumer;
114 | 
115 | import com.alibaba.dubbo.config.annotation.Reference;
116 | import com.imooc.springboot.dubbo.demo.DemoService;
117 | import org.springframework.web.bind.annotation.RequestMapping;
118 | import org.springframework.web.bind.annotation.RequestParam;
119 | import org.springframework.web.bind.annotation.RestController;
120 | 
121 | @RestController
122 | public class DemoConsumerController {
123 | 
124 |     @Reference
125 |     private DemoService demoService;
126 | 
127 |     @RequestMapping("/sayHello")
128 |     public String sayHello(@RequestParam String name) {
129 |         return demoService.sayHello(name);
130 |     }
131 | 
132 | }
133 | ```
134 | ### 3. springboot配置文件 - application.properties
135 | ```bash
136 | server.port=8080
137 | #dubbo config
138 | spring.dubbo.application.name=demo-consumer
139 | #这里使用广播的注册方式，
140 | #如果有Can't assign address异常需要加vm参数：
141 | #-Djava.net.preferIPv4Stack=true
142 | spring.dubbo.registry.address=multicast://224.5.6.7:1234
143 | spring.dubbo.scan=com.imooc.springboot.dubbo.demo.consumer
144 | ```
145 | 
146 | ### 4. 启动类
147 | ```java
148 | package com.imooc.springboot.dubbo.demo.consumer;
149 | 
150 | import org.springframework.boot.SpringApplication;
151 | import org.springframework.boot.autoconfigure.SpringBootApplication;
152 | 
153 | @SpringBootApplication
154 | public class Main {
155 | 
156 |     public static void main(String[] args) {
157 |         SpringApplication.run(Main.class,args);
158 |     }
159 | 
160 | }
161 | ```
