【JEECG Dubbo專題】jeecg-p3集成dubbo文檔

1、項目介紹

2、項目分解說明

1 . p3dubbo-service

    說明：該項目爲簡單的maven構建項目，無任何依賴引用，只做接口定義

     

  接口定義以下：

pom文件說明

  

2. p3dubbo-service

  說明：該項目爲接口實現項目，進行業務邏輯編寫

 

  接口實現以下：

@Service("demoService") public class DemoServiceImpl implements DemoServiceI { public String sayHello(String name) { System.out.println(" -- jeecg-p3-dubbo---say: "+name);                   return name + "[jeecg-p3-dubbo]";      } }

    pom以下：（引入jeecg-p3父POM,增長dubbo依賴支持）

<parent>     <groupId>org.p3framework</groupId>     <artifactId>jeecg-p3-pom</artifactId>     <version>1.0-SNAPSHOT</version> </parent> <dependencies> <!-- 接口API --> <dependency> <groupId>org.p3dubbo</groupId> <artifactId>p3dubbo-service</artifactId> <version>0.0.1-SNAPSHOT</version> <type>jar</type> <scope>compile</scope> </dependency> <!-- dubbo jar --> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.5.3</version> <exclusions>                 <exclusion>                     <groupId>org.springframework</groupId>                     <artifactId>spring</artifactId>                 </exclusion>             </exclusions> </dependency> <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>       </dependencies>

  Spring dubbo配置文件

<?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"> <!-- 提供方應用名稱信息，這個至關於起一個名字，咱們dubbo管理頁面比較清晰是哪一個應用暴露出來的 -->    <dubbo:application name="jeecgp3_dubbo_provider"></dubbo:application>    <!-- 使用zookeeper註冊中心暴露服務地址 -->      <dubbo:registry address="zookeeper://192.168.0.1:2181" check="false" subscribe="false" register=""></dubbo:registry>    <!-- 要暴露的服務接口 -->      <dubbo:service interface="com.jeecg.demo.DemoServiceI" ref="demoService" /> </beans>

3..jeecg-p3-web (啓動項目)

    說明：該項目爲jeecg-p3啓動項目，做爲服務提供項目，須要引入p3dubbo-service-impl項目

    1）引入spring dubbo配置

    2）pom引入接口實現項目 

    啓動項目jeecg-p3-web，提供服務（前臺先按照zookeeper）

4. p3dubbo-consumer(消費項目)

    

  測試類：

public class DubboConsumer { public static void main(String[] args) throws Exception { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "applicationContext.xml" });          context.start(); DemoServiceI demoService = (DemoServiceI) context.getBean("demoService"); String hello = demoService.sayHello("1998"); System.out.println(hello); } }

Spring 配置

<?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">     <!-- 消費方應用名，用於計算依賴關係，不是匹配條件，不要與提供方同樣 -->       <dubbo:application name="dubbo_consumer" />       <!-- 使用zookeeper註冊中心暴露服務地址 -->       <dubbo:registry address="zookeeper://192.168.0.1:2181" />       <!-- 生成遠程服務代理，能夠像使用本地bean同樣使用demoService -->       <dubbo:reference id="demoService"  interface="com.jeecg.demo.DemoServiceI" />   </beans>

pom引用：

<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>org.p3dubbo</groupId> <artifactId>p3dubbo-consumer</artifactId> <version>0.0.1-SNAPSHOT</version> <parent> <groupId>org.p3framework</groupId> <artifactId>jeecg-p3-pom</artifactId> <version>1.0-SNAPSHOT</version> </parent> <dependencies> <!-- api --> <dependency> <groupId>org.p3dubbo</groupId> <artifactId>p3dubbo-service</artifactId> <version>0.0.1-SNAPSHOT</version> <scope>compile</scope> </dependency> <!-- dubbo jar --> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.5.3</version> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </exclusion> </exclusions> </dependency> <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> </dependencies> </project>
