taotao-SSM+dubbo整合测试

上篇文章讲解了一下SSM框架的整合，这篇文章我们就来讲解一下dubbo+SSM进行整合的测试

# 【需求】 #

根据商品id查询商品信息，并将商品信息使用json数据返回。

# 【分析】 #

请求的url：/item/\{itemId\}

参数：商品id，从请求的url中获得

返回值：TbItem对象，逆向工程生成的pojo（响应json数据）

# 【Dao层】 #

根据商品id查询商品信息，单表查询可以使用逆向工程生成的代码。

# 【Service层】 #

1、在taotao-manager-interface工程中创建一个ItemService接口

public interface ItemService { TbItem getItemById(long itemId); }

2、在taotao-manager-Service工程中创建一个itemSeviceImpl的实现类。

@Service public class ItemServiceImpl implements ItemService { @Autowired private TbItemMapper itemMapper; @Override public TbItem getItemById(long itemId) { TbItem tbItem = itemMapper.selectByPrimaryKey(itemId); return tbItem; } }

# 【发布服务】 #

1、在taotao-manager-Service工程pom.xml中添加dubbo依赖的jar包。

<dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </exclusion> <exclusion> <groupId>org.jboss.netty</groupId> <artifactId>netty</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> </dependency> <dependency> <groupId>com.github.sgroschupf</groupId> <artifactId>zkclient</artifactId> </dependency>

2、在spring的配置文件中添加dubbo的约束，然后使用dubbo:service发布服务。

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
    	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    	xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" 
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
    	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
    	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
    	http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
    	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">
    	
    	
    	<context:component-scan base-package="com.taotao.service"/>
    	
    	
    	
    	<dubbo:application name="taotao-manager" />
    	
    	<dubbo:registry protocol="zookeeper" address="192.168.25.6:2181" />
    	
    	<dubbo:protocol name="dubbo" port="20880" />
    	
    	<dubbo:service interface="com.taotao.service.ItemService" ref="itemServiceImpl" timeout="300000"/>
    </beans>

【 引用服务 】

1、在taotao-manager-web工程pom.xml中添加dubbo依赖的jar包

2、在springmvc的配置文件中添加服务的引用

<?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-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.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-4.2.xsd">  <mvc:annotation-driven />  <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean>  <context:component-scan base-package="com.taotao.controller"/>  <mvc:resources location="/css/" mapping="/css/**"/> <mvc:resources location="/js/" mapping="/js/**"/>  <dubbo:application name="taotao-manager-web"/> <dubbo:registry protocol="zookeeper" address="192.168.25.6:2181"/> <dubbo:reference interface="com.taotao.service.ItemService" id="itemService" /> </beans>

# 【Controller】 #

@Controller public class ItemController { @Autowired private ItemService itemService; @RequestMapping("/item/{itemId}") @ResponseBody public TbItem getItemById(@PathVariable Long itemId) { //根据商品id查询商品信息 TbItem tbItem = itemService.getItemById(itemId); return tbItem; } }

# 【解决mapper映射文件不发布问题】 #

在taotao-manager-dao工程的pom文件中添加如下内容：

<build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> </resources> </build>

# 【运行结果】    #

根据商品的id=830972查出对应的商品
