4. 先点击library，然后点击File-->new-->module，建立maven web工程：dubboxDemo-Service (服务提供者)，并继承父工程
5. pom.xml
<?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>parent</artifactId> <groupId>com.zgh</groupId> <version>1.0-SNAPSHOT</version> <relativePath>../parent/pom.xml</relativePath> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>dubboxDemo-Service</artifactId> <packaging>war</packaging> <name>dubboxDemo-Service Maven Webapp</name> <!-- FIXME change it to the project's website --> <url>http://www.example.com</url> <build> <finalName>${artifactId}</finalName> <plugins> <!-- 配置Tomcat插件 --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <!--服务启动端口从9000开始--> <port>9000</port> <!--发布路径，发布到Tomcat的根目录，不用写项目(虚拟路径)名访问--> <path>/</path> <uriEncoding>UTF-8</uriEncoding> <!--插件里显示的名称--> <server>tomcat7</server> </configuration> </plugin> </plugins> </build> </project>
6. 同理建立工程：dubboxDemo-web （服务消费者）
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>parent</artifactId> <groupId>com.zgh</groupId> <version>1.0-SNAPSHOT</version> <relativePath>../parent/pom.xml</relativePath> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>dubboxDemo-web</artifactId> <packaging>war</packaging> <name>dubboxDemo-web Maven Webapp</name> <!-- FIXME change it to the project's website --> <url>http://www.example.com</url> <build> <finalName>${artifactId}</finalName> <plugins> <!-- 配置Tomcat插件 --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <!--服务启动端口从9000开始--> <port>9001</port> <!--发布路径，发布到Tomcat的根目录，不用写项目(虚拟路径)名访问--> <path>/</path> <uriEncoding>UTF-8</uriEncoding> <!--插件里显示的名称--> <server>tomcat7</server> </configuration> </plugin> </plugins> </build> </project>
四。配置dubboxDemo-Service
1. dubboxDemo-Service 工程新建接口： UserService
package com.dubboxDemo.service;
public interface UserService {
public String getName();
}
2. 实现这个接口
package com.dubboxDemo.service.impl; import com.alibaba.dubbo.config.annotation.Service; import com.dubboxDemo.service.UserService; @Service public class UserServiceImpl implements UserService { @Override public String getName() { return "我的 dubboDemo"; } }
3. 配置applicationContext-service.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:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <!--服务名称，可修改，默认为工程名--> <dubbo:application name="dubboxdemo-service"/> <!--注册地址--> <dubbo:registry address="zookeeper://10.20.0.129:2181"/> <!--实现接口的包名称--> <dubbo:annotation package="com.dubboxDemo.service.impl"/> <!--<dubbo:protocol name="dubbo" host="192.168.1.4" port="20883" />--> </beans>
4. 配置web.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> <!-- 加载spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <!--配置路径--> <param-value>classpath:applicationContext*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
五。配置dubboxDemo-web
1. 把工程dubboxDemo-Service里的接口 UserService 复制下来，包路径要两者一样
2. 实现控制器
package com.dubboxDemo.controller; import com.alibaba.dubbo.config.annotation.Reference; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import com.dubboxDemo.service.UserService; @Controller @RequestMapping("/user") public class UserController { @Reference private UserService userService; @RequestMapping("/showName") @ResponseBody public String showName(){ return userService.getName(); } }
3. 配置applicationContext-web.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:mvc="http://www.springframework.org/schema/mvc" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" 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"> <!--mvc 转换器--> <mvc:annotation-driven > <mvc:message-converters register-defaults="false"> <!--转换成字符串--> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <constructor-arg value="UTF-8" /> </bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 引用dubbo 服务 --> <dubbo:application name="dubboxdemo-web" /> <!--注册地址--> <dubbo:registry address="zookeeper://10.20.0.129:2181"/> <!--调用服务的包路径--> <dubbo:annotation package="com.dubboxDemo.controller"/> </beans>
4. 配置web.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> <!-- 解决post乱码 --> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <!--符合url的才会处理乱码--> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--所有请求由SpringMVC管理,即交给DispatcherServlet--> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--springMVC 配置文件--> <param-value>classpath:applicationContext-web.xml</param-value> </init-param> </servlet> <!--符合url的才会转交--> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
六。测试
1. 运行dubboxDemo-Service（服务提供者）
2. dubbo-admin查看，服务提供者的信息（ip地址和端口(默认20880)等）存储到了zookeepe
3. 同理启动dubboxDemo-web（服务消费者），然后浏览器输入：http://localhost:9001/user/showName.do ，服务消费者会去注册中心zookeepe拿到服务提供者的ip地址和端口(默认20880)，然后到该地址和端口调用
4. dubbo-admin查看，已经被消费了
