B2B2C-1 dubbox-4-查询品牌后台实现

三个模块:

manager(对应manager-web)运营商管理模块

sellergoods(对应sellergoods-api和sellergoods-service)商品模块

shop(对应shop-web)商家模块

利用dubbo服务实现功能调用

sellergoods-api:服务提供者api

sellergoods-service:真正的服务提供者

shop-web:服务消费者

--------------------------------------------------------------------------------具体实现--------------------------------------------------------------------------------------------------------

利用dubbo的注解方式实现

sellergoods-service中的spring配置文件内容:

<?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:protocol name="dubbo" port="20881"></dubbo:protocol>
    
   <dubbo:application name="pyg-sellergoods-service"/>
    <dubbo:registry address="zookeeper://localhost:2181"/>
    <dubbo:annotation package="com.pyg.sellergoods.service.impl" />

   <!-- 声明需要暴露的服务 -->
   <!--<dubbo:service interface="com.pyg.brand.service.BrandService" ref="brandService" />
   &lt;!&ndash; 服务实现 &ndash;&gt;
   <bean id="brandService" class="com.pyg.sellergoods.service.impl.BrandServiceImpl" />-->
   
</beans>

调用者的spring配置文件内容:

<?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">
    <context:property-placeholder location="classpath:config/application.properties" />
    <context:component-scan base-package="com.pyg.manager.controller" />
   <mvc:annotation-driven>
     <mvc:message-converters register-defaults="true">
       <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">  
         <property name="supportedMediaTypes" value="application/json"/>
         <property name="features">
           <array>
             <value>WriteMapNullValue</value>
             <value>WriteDateUseDateFormat</value>
           </array>
         </property>
       </bean>
     </mvc:message-converters>  
   </mvc:annotation-driven>

   <!-- 引用dubbo 服务 -->
   <dubbo:application name="pyg-manager-web" />
   <dubbo:registry address="zookeeper://localhost:2181"/>
   <dubbo:annotation package="com.pyg.manager.controller" />
   <!--<dubbo:reference id="brandService" interface="com.pyg.brand.service.BrandService"/>-->

</beans>
注意因为web.xml文件中配置的路径是<servlet-mapping>中的<url-pattern>*.do<....>
所以@RequestMapping("/getAllBrand.do") 访问路径必须是.do的形式
