Springboot + Dubbo 構建多模塊項目 (三)

5.接着上一節內容，我們來創建springboot-api

在springboot-parent 項目上右擊>New->Module後，選擇Spring Initializr，默認使用的Java版本是1.8。

對應的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"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.myapp</groupId>
    <artifactId>springboot-api</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>springboot-api</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

        </dependency>
        <!--引入dubbo的依賴-->

            <groupId>com.alibaba.spring.boot</groupId>

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

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

                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!--解決maven打包報錯-->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.4.2</version>
                <configuration>
                    <skipTests>true</skipTests>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

  創建Controller:

package com.myapp.core.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.myapp.HelloService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author :zzb
 * @createDate :2019/6/25 16:04
 * @desc :
 */
@RestController
public class HelloController {

    @Reference
    private HelloService helloService;

    @RequestMapping("/hello")
    public String hello() {
        System.out.println("------------------001---------------------執行api--------------------------------");
        String hello = helloService.sayHello("Hello world");

        return hello;
    }
}

  在啓動類上添加dubbo註解 @EnableDubboConfiguration:

package com.myapp.core;

import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableDubboConfiguration
public class SpringbootApiApplication {

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

}

Resources目錄下默認生成Springboot配置文件爲application.properties配置文件，建議重新添加application.yml

##服務端口
server:
  port: 80

spring:
  dubbo:
    application:
      name: dubbo-consuter
      registry: zookeeper://192.168.1.102:2181

修改爲自己相應的zookeeper註冊地址。

至此，整個項目結構已經構建完成，接下來使用Maven進行打包運行。

   1.先進行重新編譯：

2.啓動 springboot-service 服務

成功啓動，控制檯顯示：

3.啓動 springboot-api 服務,和啓動 springboot-service 服務一樣的。成功控制檯顯示：

打開瀏覽器，輸入http://localhost:80/hello  瀏覽器正常運行。
