**由于最近项目需要SpringMVC集成Dubbo，本文大概记录下详细集成过程：**

一、首先项目中Maven引入Jar包

<dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>dubbo</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.apache.zookeeper</groupId>
                <artifactId>zookeeper</artifactId>
                <version>${zookeeper.version}</version>
            </dependency>

二、web.xml配置context-param（生产者）

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
          classpath*:config/datasource.xml
          classpath*:spring/*.xml
        </param-value>
      </context-param>

三、 配置spring-dubbo-provider.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: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">
    
        
        <dubbo:application name="demo-provider"/>
    
        
        <dubbo:registry address="zookeeper://127.0.0.1:2181"/>
    
        
        <dubbo:protocol name="dubbo" port="20880"/>
    
        
        <dubbo:annotation package="com.ls"/>
    
    </beans>

四、 class注册成生产者

@Transactional
    @Service
    public class UserServiceImpl implements IUserService {
    
    }

五、web.xml配置servlet（消费者）

<servlet>
            <servlet-name>dispatcherServlet</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>classpath:spring/spring-mvc-dubbo.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>

六、配置spring-mvc-dubbo.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: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/context
    	   http://www.springframework.org/schema/context/spring-context.xsd
           http://code.alibabatech.com/schema/dubbo
           http://code.alibabatech.com/schema/dubbo/dubbo.xsd
           http://www.springframework.org/schema/mvc
    	   http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
        
        <dubbo:application name="consumer"/>
    
        
        <dubbo:registry address="zookeeper://127.0.0.1:2181"/>
    
        
        <dubbo:annotation package="com.ls"/>
    
        
    
        <bean id="stringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter">
            <constructor-arg value="UTF-8"/>
            <property name="supportedMediaTypes">
                <list>
                    <value>text/html;charset=utf-8</value>
                    <value>application/xml;charset=utf-8</value>
                    <value>application/json;charset=utf-8</value>
                </list>
            </property>
        </bean>
    
        <bean id="mappingJackson2HttpMessageConverter"
              class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="prefixJson" value="false"/>
            <property name="supportedMediaTypes">
                <list>
                    <value>text/html;charset=utf-8</value>
                    <value>application/xml;charset=utf-8</value>
                    <value>application/json;charset=utf-8</value>
                </list>
            </property>
            <property name="objectMapper" ref="objectMapper"></property>
        </bean>
    
        <bean id="objectMapper" class="com.fasterxml.jackson.databind.ObjectMapper">
            <property name="dateFormat">
                <bean class="java.text.SimpleDateFormat">
                    <constructor-arg value="yyyy-MM-dd HH:mm:ss" />
                </bean>
            </property>
        </bean>
    
        <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
            <property name="maxUploadSize" value="50000000"/>
            <property name="maxUploadSizePerFile" value="5000000"/>
            <property name="defaultEncoding" value="utf-8"/>
        </bean>
    
        <mvc:annotation-driven >
            <mvc:message-converters>
                <ref bean="stringHttpMessageConverter"/>
                <ref bean="mappingJackson2HttpMessageConverter"/>
            </mvc:message-converters>
        </mvc:annotation-driven>
    
    
    </beans>

七、 class中引入消费者

@Reference
        private IUserService userService;

至此SpringMVC集成Dubbo注解配置方式以基本完成。
