spring MVC整合dubbo实例二

spring 整合dubbo

一、创建服务提供者 (创建多模块项目的目的是将服务的接口和实现分开)

1.1、在提供者的pom文件中添加依赖(我这里使用的是dubbo-2.5.10版本,版本不同可能依赖版本不同,这里有坑 需要注意)

<!--dubbo -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.5.10</version>
        </dependency>
 
        <!--zookeeper -->
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.6</version>
        </dependency>
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.1</version>
        </dependency>

1.2、在服务提供者的spring配置文件中增加dubbo的配置信息

<?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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:util="http://www.springframework.org/schema/util"
       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/context
            http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/mvc
            http://www.springframework.org/schema/mvc/spring-mvc.xsd
            http://www.springframework.org/schema/util
            http://www.springframework.org/schema/util/spring-util.xsd
            http://code.alibabatech.com/schema/dubbo
            http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
 
    <!-- 组件扫描-->
    <context:component-scan base-package="com.aliyun.dubbo"/>
 
    <!-- 注解驱动 -->
    <mvc:annotation-driven/>
 
    <!-- 静态资源放行 -->
    <mvc:default-servlet-handler/>
 
    <!-- 视图解析 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
 
    <dubbo:application name="dubbo-demo"></dubbo:application>
    <dubbo:registry address="zookeeper://127.0.0.1:2181" check="false" subscribe="false"></dubbo:registry>
    <dubbo:protocol name="dubbo" port="20880"></dubbo:protocol>
    <dubbo:service interface="com.demo.dubbo.cwl.api.DemoApi" ref="DemoServiceImp"></dubbo:service>
</beans>

1.3 、启动项目 若无报错则dubbo服务提供成功

二、创建服务消费者

      创建项目

2.1、在消费者的pom文件中添加依赖(我这里使用的是dubbo-2.5.10版本,版本不同可能依赖版本不同,这里有坑 需要注意)

<!--dubbo -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.5.10</version>
        </dependency>
 
        <!--zookeeper -->
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.6</version>
        </dependency>
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.1</version>
        </dependency>

2.2、在服务消费者的spring配置文件中增加dubbo的配置信息

<?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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:util="http://www.springframework.org/schema/util"
       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/context
            http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/mvc
            http://www.springframework.org/schema/mvc/spring-mvc.xsd
            http://www.springframework.org/schema/util
            http://www.springframework.org/schema/util/spring-util.xsd
            http://code.alibabatech.com/schema/dubbo
            http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
 
    <!-- 组件扫描-->
    <context:component-scan base-package="com.aliyun.dubbo"/>
 
    <!-- 注解驱动 -->
    <mvc:annotation-driven/>
 
    <!-- 静态资源放行 -->
    <mvc:default-servlet-handler/>
 
    <!-- 视图解析 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
 
    <dubbo:application name="dubbo-demo"></dubbo:application>
    <dubbo:registry address="zookeeper://127.0.0.1:2181" check="false" subscribe="true"></dubbo:registry>
    <dubbo:protocol port="20880"></dubbo:protocol>
    <dubbo:reference id ="questionApi" interface="com.demo.dubbo.cwl.api.DemoApi"></dubbo:reference>
 
</beans>

2.3、启动应用若无报错 则证明成功 调用接口验证

三、启动监控中心

      监控中心  下载

      dubbo-admin-2.5.10 然后放到tomcat的ROOT目录下,启动tomcat 

这里默认的注册中心是zookeeper:127.0.0.1:2181

启动tomcat后可以看到服务的提供者和服务的消费者
