springboot2.2.2集成dubbo的实现方法
最近在学习dubbo,想着作一些笔记,从来没有在csdn上面写过博客,今天献出第一次,哈哈,直接上代码
一、创建父工程
<?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> <!--统一管理依赖版本--> <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> <!-- 连接zookeeper的依赖,我的zookeeper版本是3.4.14,感觉这个jar版本和zookeeper是大概保持一致的,但是引入3.4.14会报错,我试了下,从3.4.13开始就不行了 --> <zookeeper.version>3.4.12</zookeeper.version> </properties> <!--依赖定义--> <!--dependencyManagement 定义依赖版本号。子工程直接加依赖即可,不需要再次加版本号,便于统一维护版本号--> <dependencyManagement> <dependencies> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> <version>${dubbo.version}</version> </dependency> <!-- zookeeper的api管理依赖 --> <dependency> <groupId>org.apache.curator</groupId> <artifactId>curator-recipes</artifactId> <version>${curator.version}</version> </dependency> <!-- zookeeper依赖 --> <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> <!-- 使用该依赖,idea需要安装插件,没有用过的自行百度一下吧 --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> </dependencies> </project>
二、创建提供者与消费者共用的api
该模块没有什么好说的,提供者和消费者都需要使用的接口api,提供者和消费者都需要引入该模块
<?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、创建提供者
<?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> <!-- 导入公共接口依赖 --> <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: # 应用名称 name: user-provider protocol: # 协议名称 name: dubbo # 协议端口 port: 20880 registry: # 注册中心地址 address: zookeeper://192.168.104.231:2181
@SpringBootApplication // 提供服务的应用必须配置此项 @DubboComponentScan("com.dubbo.provider.service") public class ProviderApplication { public static void main(String[] args) { SpringApplication.run(ProviderApplication.class, args); } }
@Component // 该service是org.apache.dubbo.config.annotation.Service @Service public class UserServiceImpl implements UserService { @Override public User getUserById(Integer id) { User user = User.builder() .id(id) .name("张三") .age(20 + id) .build(); return user; } }
四、创建消费者
<?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> <!-- 导入公共接口依赖 --> <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: 8081 dubbo: application: name: user-consumer protocol: name: dubbo port: 20880 registry: address: zookeeper://192.168.104.231:2181
@SpringBootApplication public 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、启动并访问
先启动provider,启动结果如下
启动consumer,启动结果如下
浏览器访问:http://localhost:8081/user/4
好了,到此就完成了最基本的springboot与dubbo的整合,更多的dubbo的api请查阅 dubbo官方文档
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
