dubbo入门小demo服务提供者和消费者开发

Myth丶恋晨 2022-02-27 14:44 276阅读 0赞

### 需求：服务的提供者主要提供一个名字 消费者调用这个名字 ###

### 接下来说说怎么做 ###

### 第一步：搭建一个普通的maven 项目 这里需要注意 pom要选择 war （下图报错是因为缺少web.xml文件稍后我会处理） ###

### 第二步引入相关的依赖（这里要注意这个dubbo的jar包在maven中央仓库可能没有） ###

### 下载这个包的地址：[https://download.csdn.net/download/onlyonefrist/11062057][https_download.csdn.net_download_onlyonefrist_11062057] ###

### pom.xml文件如下 ###

    				</configuration>
    	  	  </plugin>
    	  </plugins>  
        </build>
    </project>

### 第三步导入web.xml文件（现在项目也不报错了） ###

### web.xml文件如下 ###

### 第四步写applicationContext-service.xml配置文件（这里需要注意的是zookeeper的ip需要换成自己的） ###

<?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">
           
           <dubbo:application name="dubboxdemo-service"/>
           
           <dubbo:registry address="zookeeper://192.168.239.128:2181"/>
           
           <dubbo:annotation package="com.zuojie.demo.service.impl"/>
       
       
    </beans>

### 第五步创建一个接口 ###

### 写实现类 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L09ubHlvbmVGcmlzdA_size_16_color_FFFFFF_t_70 3][]

### 到这里一个简单的提供者就写完了 ###

### 接下来写消费者 ###

### 消费者的项目结构 ###

### 第一步：搭建一个普通的maven项目 pom的类型选择war ###

### 第二步：引入相关的依赖这里的依赖和提供者的依赖一样 ###

    	  </plugins>  
        </build>
    </project>

### 第二步写web.xml文件  ###

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns="http://java.sun.com/xml/ns/javaee"
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    	version="2.5">	
       
    	<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>
    	<filter-mapping>
    		<filter-name>CharacterEncodingFilter</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>	
    	
      <servlet>
      	<servlet-name>springmvc</servlet-name>
      	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      	
      	<init-param>
      		<param-name>contextConfigLocation</param-name>
      		<param-value>classpath:springmvc.xml</param-value>
      	</init-param>
      </servlet>
      
      <servlet-mapping>
      	<servlet-name>springmvc</servlet-name>
      	<url-pattern>*.do</url-pattern>
      </servlet-mapping>
    
    
     
    	
    </web-app>

### 第三步写springmvc.xml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: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">
    
        
    	<mvc:annotation-driven >
    		<mvc:message-converters register-defaults="false">
    			<bean class="org.springframework.http.converter.StringHttpMessageConverter">  
    				<constructor-arg value="UTF-8" />
    			</bean>  
    		</mvc:message-converters>	
    	</mvc:annotation-driven>
    	    
           <dubbo:application name="dubboxdemo-web"/>
           
           <dubbo:registry address="zookeeper://192.168.239.128:2181"/>
           
           <dubbo:annotation package="com.zuojie.demo.controller"/>
       
    
    
    </beans>

### 第四步写相应的业务代码![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L09ubHlvbmVGcmlzdA_size_16_color_FFFFFF_t_70 5][] ###

### 到这里消费者也实现了 ###

### 接下来我们来启动  ###

### 第一步先启动zookeeper 我的zookeeper是安装在虚拟机里面的 zookeeper安装详见[https://mp.csdn.net/postedit/88776102][https_mp.csdn.net_postedit_88776102] ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L09ubHlvbmVGcmlzdA_size_16_color_FFFFFF_t_70 7][]

### 第二步启动提供服务者 项目—》右键—》run as maven build  ###

### 第二步运行消费者 ###

### 访问成功 ###
