以zookeeper为注册中心springmvc集成dubbo的服务实现

一.创建一个web项目，作为dubbo的消费者

1.pom.xml

<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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion>

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

2.配置spring-dubbo.xml

<!--消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->
<dubbo:application name="项目名称" />
<!-- 扫描注解包路径，多个包用逗号分隔，不填pacakge表示扫描当前ApplicationContext中所有的类 -->
<dubbo:annotation package="com.xx.xx.jobinterface.*" />
<!-- 注册中心地址 -->
<dubbo:registry protocol="zookeeper" address="192.168.xx.xx:2181,192.168.xx.xx:2182,192.168.xx.xx:2
b06b
183" />

<!-- 协议 -->
<dubbo:protocol name="dubbo" port="20881" />

<!-- 生成远程服务代理，可以和本地bean一样使用demoService -->
<dubbo:reference id="xxService" check="false" interface="com.xx.ida.jobinterface.service.xxService"/>

<!-- 包扫描 -->
<context:component-scan base-package="com.xx.ida.jobinterface.*">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<context:component-scan base-package="com.ida"></context:component-scan>
<!-- s
通知事务管理使用注解管理
spring动态代理
proxy-target-class="false"
false	jdk		基于接口
true	cglib	基于类
-->
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="false"/>

3.配置springmvc.xml

<!-- 声明扫描包路径 -->
<context:component-scan base-package="com.xx.ida.jobinterface.controller"></context:component-scan>
<!-- springMVC基于注解开发的驱动配置 -->
<mvc:annotation-driven>
<!-- 用FastJson替换了默认的json序列化方案：Jackson -->
<mvc:message-converters>
<bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
<!-- json的content-type是application/json  支持的格式为json -->
<property name="supportedMediaTypes" value="application/json"></property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"></bean>
<!-- 视图解析器
接收到后端和控制器的返回值，并根据返回值解析出对应的视图
解析过程：前缀(prefix)+返回值+后缀(suffix)=跳转的视图
-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 静态资源访问问题解决
会多注册Handler，且，其url-pattern为 /**
且其会在最后匹配请求，匹配到后，直接导向对应的静态资源
-->
<mvc:default-servlet-handler/>

4.配置web.xml

<web-app id="WebApp_1492051741622">
<display-name></display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring.xml
</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
<servlet-name>mvc</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>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>mvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

5.将htt请求传入参数封装成pojo，作为数据传输对象（DTO），将pojo类和暴露的接口打成jar引入到maven项目中。便于代码逻辑的修改

6.创建Manager，控制层（controller）调用manager，manager将参数封装成pojo，并调用暴露的接口
控制层，接收请求，调用Manager

@RequestMapping(value = "/create_MethodJob", method = { RequestMethod.POST })
public @ResponseBody CreateJobOutputDto ida_pdata_create_task(String functionname){
return jobManager.create(functionname);
}

Manager,将参数封装为pojo,并调用暴露的接口

public CreateJobOutputDto create(String functionname){
CreateJobInputDto createJobInputDto = new CreateJobInputDto();
createJobInputDto.setFunctionname(functionname);
return jobService.createTask(createJobInputDto);
}

二.创建java项目作为dubbo服务的提供者，并打成jar保证在windows或linux可以正常运行

1.首先 要在pom文件里加以下内容（同上），保证打包过程将所有引用jar打进去。并生命jar的入口函数

<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<appendAssemblyId>false</appendAssemblyId>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>com.dubbo.test.Start</mainClass><!-- 要执行的类得路径 -->
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>assembly</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.dubbo.test.Start</mainClass><!-- 要执行的类得路径 -->
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.handlers</resource>
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.schemas</resource>
</transformer>
</transformers>
<shadedArtifactAttached>true</shadedArtifactAttached>
<!-- optional -->
<shadedClassifierName>executable</shadedClassifierName>
</configuration>
</execution>
</executions>
</plugin>

2.然后需要在src/main/resource目录下新建META-INF文件夹在此文件夹下新建MANIFEST.MF、spring.handlers、spring.schemas这三个空文件
maven 命令 assembly:assembly
