今天就跟大家聊聊有關(guān)Dubbo如何實(shí)現(xiàn)調(diào)用,可能很多人都不太了解,為了讓大家更加了解,小編給大家總結(jié)了以下內(nèi)容,希望大家根據(jù)這篇文章可以有所收獲。
1、創(chuàng)建maven工程(打包方式為war)dubbodemo_provider,在pom.xml文件中導(dǎo)入如下坐標(biāo)
~~~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相關(guān) -->
<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>
<!-- 請(qǐng)求路徑 -->
<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、創(chuàng)建服務(wù)接口
~~~java
package com.itheima.service;
public interface HelloService {
public String sayHello(String name);
}
~~~
4、創(chuàng)建服務(wù)實(shí)現(xiàn)類
~~~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:服務(wù)實(shí)現(xiàn)類上使用的Service注解是Dubbo提供的,用于對(duì)外發(fā)布服務(wù)
5、在src/main/resources下創(chuàng)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">
<!-- 當(dāng)前應(yīng)用名稱,用于注冊(cè)中心計(jì)算應(yīng)用間依賴關(guān)系,注意:消費(fèi)者和提供者應(yīng)用名不要一樣 -->
<dubbo:application name="dubbodemo_provider" />
<!-- 連接服務(wù)注冊(cè)中心zookeeper ip為zookeeper所在服務(wù)器的ip地址-->
<dubbo:registry address="zookeeper://192.168.134.129:2181"/>
<!-- 注冊(cè) 協(xié)議和port 端口默認(rèn)是20880 -->
<dubbo:protocol name="dubbo" port="20881"></dubbo:protocol>
<!-- 掃描指定包,加入@Service注解的類會(huì)被發(fā)布為服務(wù) -->
<dubbo:annotation package="com.itheima.service.impl" />
</beans>
~~~
6、啟動(dòng)服務(wù)
tomcat7:run
