SpringBoot整合dubbo

时间：2025-02-22 09:07:44

Dubbo是阿里巴巴公司开源的一个高性能优秀的服务框架，使得应用可通过高性能的 RPC 实现服务的输出和输入功能，可以和Spring框架无缝集成。

以上介绍来源于百度百科，具体dubbo相关可以自行查找资料，本文只是介绍SpringBoot简单整合dubbo。

1.安装zookeeper

1.1 去官网下载，本文以3.4.12 版本为例子http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.12/

1.2 下载之后解压ZooKeeper

1.3 进入解压文件夹conf目录

1.4 将zoo_sample.cfg修改名称为zoo.cfg

1.5 修改内容为如下，注意，本人是将ZooKeeper解压到了e盘，具体

dataDir和dataDirLog属性可以根据自己情况修改。

# The number of milliseconds of each tick

tickTime=2000

# The number of ticks that the initial

# synchronization phase can take

initLimit=10

# The number of ticks that can pass between

# sending a request and getting an acknowledgement

syncLimit=5

# the directory where the snapshot is stored.

# do not use /tmp for storage, /tmp here is just

# example sakes.

dataDir=E:\\zookeeper\\data

dataDirLog=E:\\zookeeper\\log

# the port at which the clients will connect

clientPort=2181

# the maximum number of client connections.

# increase this if you need to handle more clients

#maxClientCnxns=60

#

# Be sure to read the maintenance section of the

# administrator guide before turning on autopurge.

#

# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

#

# The number of snapshots to retain in dataDir

#autopurge.snapRetainCount=3

# Purge task interval in hours

# Set to "0" to disable auto purge feature

#autopurge.purgeInterval=1

1.6 启动zookeeper，进入bin目录，双击zkServer.cmd

2 新建项目springboot_dubbo_server，项目中加入dubbo依赖，完整pom如下：

<?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>

    <groupId>com.dalaoyang</groupId>

    <artifactId>springboot_dubbo_server</artifactId>

    <version>0.0.1-SNAPSHOT</version>

    <packaging>jar</packaging>

    <name>springboot_dubbo_server</name>

    <description>springboot_dubbo_server</description>

    <parent>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-parent</artifactId>

        <version>1.5.9.RELEASE</version>

        <relativePath/> <!-- lookup parent from repository -->

    </parent>

    <properties>

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

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

    </properties>

    <dependencies>

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter</artifactId>

        </dependency>

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-test</artifactId>

            <scope>test</scope>

        </dependency>

        <dependency>

            <groupId>io.dubbo.springboot</groupId>

            <artifactId>spring-boot-starter-dubbo</artifactId>

            <version>1.0.0</version>

        </dependency>

    </dependencies>

    <build>

        <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

            </plugin>

        </plugins>

    </build>

</project>

配置文件如下：

##端口号

server.port=8880

## Dubbo 服务提供者配置

spring.dubbo.application.name=dubbo_server

spring.dubbo.registry.address=zookeeper://39.108.123.128:2181

spring.dubbo.protocol.name=dubbo

spring.dubbo.protocol.port=20880

spring.dubbo.scan=com.dalaoyang.dubbo

定义一个Service Interface：HelloService.java

package com.dalaoyang.dubbo;

/**

 * @author dalaoyang

 * @Description

 * @project springboot_learn

 * @package com.dalaoyang.dubbo

 * @email yangyang@dalaoyang.cn

 * @date 2018/6/14

 */

public interface HelloService {

    String SayHello(String name);

}

接口的实现类：HelloServiceImpl.java

package com.dalaoyang.dubbo.imp;

import com.alibaba.dubbo.config.annotation.Service;

import com.dalaoyang.dubbo.HelloService;

/**

 * @author dalaoyang

 * @Description

 * @project springboot_learn

 * @package com.dalaoyang.dubbo.imp

 * @email yangyang@dalaoyang.cn

 * @date 2018/6/14

 */

@Service(version = "1.0.0")

public class HelloServiceImpl implements HelloService {

    @Override

    public String SayHello(String name) {

        return "Hello , "+name;

    }

}

到这里dubbo服务提供者已经创建完成。

3.新建项目springboot_dubbo_client，pom与提供者一致，代码如下：

<?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>

    <groupId>com.dalaoyang</groupId>

    <artifactId>springboot_dubbo_client</artifactId>

    <version>0.0.1-SNAPSHOT</version>

    <packaging>jar</packaging>

    <name>springboot_dubbo_client</name>

    <description>springboot_dubbo_client</description>

    <parent>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-parent</artifactId>

        <version>1.5.9.RELEASE</version>

        <relativePath/> <!-- lookup parent from repository -->

    </parent>

    <properties>

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

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

    </properties>

    <dependencies>

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter</artifactId>

        </dependency>

        <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>

        </dependency>

        <dependency>

            <groupId>io.dubbo.springboot</groupId>

            <artifactId>spring-boot-starter-dubbo</artifactId>

            <version>1.0.0</version>

        </dependency>

    </dependencies>

    <build>

        <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

            </plugin>

        </plugins>

    </build>

</project>

配置文件如下：

## 端口号

server.port=8881

## Dubbo 服务消费者配置

spring.dubbo.application.name=dubbo_client

spring.dubbo.registry.address=zookeeper://39.108.123.128:2181

spring.dubbo.scan=com.dalaoyang.controller

HelloService接口如下：

package com.dalaoyang.dubbo;

/**

 * @author dalaoyang

 * @Description

 * @project springboot_learn

 * @package com.dalaoyang.dubbo

 * @email yangyang@dalaoyang.cn

 * @date 2018/6/14

 */

public interface HelloService {

    String SayHello(String name);

}

创建一个controller进行测试，注意版本号要与提供者的版本号一致，dubbo扫描包要扫描到我们要使用的类上，代码如下：

package com.dalaoyang.controller;

import com.alibaba.dubbo.config.annotation.Reference;

import com.dalaoyang.dubbo.HelloService;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.RestController;

/**

 * @author dalaoyang

 * @Description

 * @project springboot_learn

 * @package com.dalaoyang.controller

 * @email yangyang@dalaoyang.cn

 * @date 2018/6/14

 */

@RestController

public class HelloController {

    @Reference(version = "1.0.0")

    HelloService helloService;

    @GetMapping("sayHello")

    public String sayHello(String name){

        return helloService.SayHello(name);

    }

}

到这里dubbo服务调用者也创建完成。

分别启动服务提供者项目和服务调用者项目，在浏览器访问http://localhost:8881/sayHello?name=dalaoyang，如图，证明调用成功。
