如何進行springboot2.2.2集成dubbo的實現

本篇文章為大家展示了如何進行springboot2.2.2集成dubbo的實現，內容簡明扼要并且容易理解，絕對能使你眼前一亮，通過這篇文章的詳細介紹希望你能有所收獲。

最近在學習dubbo，想著作一些筆記，從來沒有在csdn上面寫過博客，今天獻出第一次，哈哈，直接上代碼

一、創建父工程

<?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>2.2.2.RELEASE</version>    <relativePath/>  </parent>  <groupId>com.dubbo</groupId>  <artifactId>demo01</artifactId>  <version>1.0.0</version>  <packaging>pom</packaging>  <description>Spring Boot2.x 整合 dubbo</description>  <modules>    <module>api</module>    <module>provider</module>    <module>consumer</module>  </modules>  <!--統一管理依賴版本-->  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>    <java.version>1.8</java.version>    <dubbo.version>2.7.5</dubbo.version>    <curator.version>4.2.0</curator.version>    <!-- 連接zookeeper的依賴，我的zookeeper版本是3.4.14，感覺這個jar版本和zookeeper是大概保持一致的，但是引入3.4.14會報錯，我試了下，從3.4.13開始就不行了 -->    <zookeeper.version>3.4.12</zookeeper.version>  </properties>  <!--依賴定義-->  <!--dependencyManagement 定義依賴版本號。子工程直接加依賴即可，不需要再次加版本號，便于統一維護版本號-->  <dependencyManagement>    <dependencies>      <dependency>        <groupId>org.apache.dubbo</groupId>        <artifactId>dubbo-spring-boot-starter</artifactId>        <version>${dubbo.version}</version>      </dependency>  <!-- zookeeper的api管理依賴 -->      <dependency>        <groupId>org.apache.curator</groupId>        <artifactId>curator-recipes</artifactId>        <version>${curator.version}</version>      </dependency>  <!-- zookeeper依賴 -->      <dependency>        <groupId>org.apache.zookeeper</groupId>        <artifactId>zookeeper</artifactId>        <version>${zookeeper.version}</version>      </dependency>    </dependencies>  </dependencyManagement>  <dependencies>    <dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-devtools</artifactId>      <scope>runtime</scope>      <optional>true</optional>    </dependency>    <!-- 使用該依賴，idea需要安裝插件，沒有用過的自行百度一下吧 -->    <dependency>      <groupId>org.projectlombok</groupId>      <artifactId>lombok</artifactId>      <optional>true</optional>    </dependency>  </dependencies></project>

二、創建提供者與消費者共用的api

該模塊沒有什么好說的，提供者和消費者都需要使用的接口api，提供者和消費者都需要引入該模塊

<?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">  <parent>    <artifactId>demo01</artifactId>    <groupId>com.dubbo</groupId>    <version>1.0.0</version>  </parent>  <modelVersion>4.0.0</modelVersion>  <artifactId>api</artifactId></project>

// 注解都是lombok的，真的很方便@Data@Builder@NoArgsConstructor@AllArgsConstructor(access = AccessLevel.PRIVATE)public class User implements Serializable {  private Integer id;  private String name;  private Integer age;}

public interface UserService {  User getUserById(Integer id);}

三、創建提供者

<?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.dubbo</groupId>    <version>1.0.0</version>    <artifactId>demo01</artifactId>  </parent>  <groupId>com.dubbo</groupId>  <artifactId>provider</artifactId>  <version>0.0.1-SNAPSHOT</version>  <name>provider</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.apache.dubbo</groupId>      <artifactId>dubbo-spring-boot-starter</artifactId>    </dependency>    <dependency>      <groupId>org.apache.curator</groupId>      <artifactId>curator-recipes</artifactId>    </dependency>    <dependency>      <groupId>org.apache.zookeeper</groupId>      <artifactId>zookeeper</artifactId>    </dependency>    <!-- 導入公共接口依賴 -->    <dependency>      <groupId>com.dubbo</groupId>      <artifactId>api</artifactId>      <version>1.0.0</version>    </dependency>    <dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-starter-test</artifactId>      <scope>test</scope>      <exclusions>        <exclusion>          <groupId>org.junit.vintage</groupId>          <artifactId>junit-vintage-engine</artifactId>        </exclusion>      </exclusions>    </dependency>  </dependencies>  <build>    <plugins>      <plugin>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-maven-plugin</artifactId>      </plugin>    </plugins>  </build></project>

dubbo: application:  # 應用名稱  name: user-provider protocol:  # 協議名稱  name: dubbo  # 協議端口  port: 20880 registry:  # 注冊中心地址  address: zookeeper://192.168.104.231:2181

@SpringBootApplication// 提供服務的應用必須配置此項@DubboComponentScan("com.dubbo.provider.service")public class ProviderApplication {  public static void main(String[] args) {    SpringApplication.run(ProviderApplication.class, args);  }}

@Component// 該service是org.apache.dubbo.config.annotation.Service@Servicepublic class UserServiceImpl implements UserService {  @Override  public User getUserById(Integer id) {    User user = User.builder()        .id(id)        .name("張三")        .age(20 + id)        .build();    return user;  }}

四、創建消費者

<?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.dubbo</groupId>    <version>1.0.0</version>    <artifactId>demo01</artifactId>  </parent>  <groupId>com.dubbo</groupId>  <artifactId>consumer</artifactId>  <version>0.0.1-SNAPSHOT</version>  <name>consumer</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.apache.dubbo</groupId>      <artifactId>dubbo-spring-boot-starter</artifactId>    </dependency>    <dependency>      <groupId>org.apache.curator</groupId>      <artifactId>curator-recipes</artifactId>    </dependency>    <dependency>      <groupId>org.apache.zookeeper</groupId>      <artifactId>zookeeper</artifactId>    </dependency>    <!-- 導入公共接口依賴 -->    <dependency>      <groupId>com.dubbo</groupId>      <artifactId>api</artifactId>      <version>1.0.0</version>    </dependency>    <dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-starter-test</artifactId>      <scope>test</scope>      <exclusions>        <exclusion>          <groupId>org.junit.vintage</groupId>          <artifactId>junit-vintage-engine</artifactId>        </exclusion>      </exclusions>    </dependency>  </dependencies>  <build>    <plugins>      <plugin>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-maven-plugin</artifactId>      </plugin>    </plugins>  </build></project>

# 端口server: port: 8081dubbo: application:  name: user-consumer protocol:  name: dubbo  port: 20880 registry:  address: zookeeper://192.168.104.231:2181

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

@RestController@RequestMapping("/user")public class ConsumerController {  @Reference  private UserService userService;  @GetMapping("/{id}")  public User getUserById(@PathVariable int id) {    return userService.getUserById(id);  }}

五、啟動并訪問

啟動provider

啟動consumer

瀏覽器訪問：http://localhost:8081/user/4
