今天就跟大家聊聊有关Dubbo如何实现调用，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

1、创建maven工程（打包方式为war）dubbodemo_provider，在pom.xml文件中导入如下坐标

~~~xml

<properties>

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

<maven.compiler.source>1.8</maven.compiler.source>

<maven.compiler.target>1.8</maven.compiler.target>

<spring.version>5.0.5.RELEASE</spring.version>

</properties>

<dependencies>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-context</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-beans</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-webmvc</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-jdbc</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-aspects</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-jms</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-context-support</artifactId>

<version>${spring.version}</version>

</dependency>

<!-- dubbo相关 -->

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>dubbo</artifactId>

<version>2.6.0</version>

</dependency>

<dependency>

<groupId>org.apache.zookeeper</groupId>

<artifactId>zookeeper</artifactId>

<version>3.4.7</version>

</dependency>

<dependency>

<groupId>com.github.sgroschupf</groupId>

<artifactId>zkclient</artifactId>

<version>0.1</version>

</dependency>

<dependency>

<groupId>javassist</groupId>

<artifactId>javassist</artifactId>

<version>3.12.1.GA</version>

</dependency>

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>fastjson</artifactId>

<version>1.2.47</version>

</dependency>

</dependencies>

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<version>2.3.2</version>

<configuration>

<source>1.8</source>

<target>1.8</target>

</configuration>

</plugin>

<plugin>

<groupId>org.apache.tomcat.maven</groupId>

<artifactId>tomcat7-maven-plugin</artifactId>

<configuration>

<!-- 指定端口 -->

<port>8081</port>

<!-- 请求路径 -->

<path>/</path>

</configuration>

</plugin>

</plugins>

</build>

2、配置web.xml文件

~~~xml

<!DOCTYPE web-app PUBLIC

"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

"http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

<display-name>Archetype Created Web Application</display-name>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext*.xml</param-value>

</context-param>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

</web-app>

~~~

3、创建服务接口

~~~java

package com.itheima.service;

public interface HelloService {

public String sayHello(String name);

}

~~~

4、创建服务实现类

~~~java

package com.itheima.service.impl;

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

import com.itheima.service.HelloService;

@Service

public class HelloServiceImpl implements HelloService {

public String sayHello(String name) {

return "hello " + name;

}

}

~~~

注意：服务实现类上使用的Service注解是Dubbo提供的，用于对外发布服务

5、在src/main/resources下创建applicationContext-service.xml

~~~xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:p="http://www.springframework.org/schema/p"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"

xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc.xsd

http://code.alibabatech.com/schema/dubbo

http://code.alibabatech.com/schema/dubbo/dubbo.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context.xsd">

<!-- 当前应用名称，用于注册中心计算应用间依赖关系，注意：消费者和提供者应用名不要一样 -->

<dubbo:application name="dubbodemo_provider" />

<!-- 连接服务注册中心zookeeper ip为zookeeper所在服务器的ip地址-->

<dubbo:registry address="zookeeper://192.168.134.129:2181"/>

<!-- 注册 协议和port 端口默认是20880 -->

<dubbo:protocol name="dubbo" port="20881"></dubbo:protocol>

<!-- 扫描指定包，加入@Service注解的类会被发布为服务 -->

<dubbo:annotation package="com.itheima.service.impl" />

</beans>

~~~

6、启动服务

tomcat7:run
