SpringMVC和dubbo简单的整合（附Demo）
顺便记录下apache产品提供下载的网址：http://mirrors.shuosc.org/apache/
第一步：
下载zookeeper，网址：http://mirrors.shuosc.org/apache/zookeeper/
启动zookeeper，直接解压后，打开bin目录，双击zkServer.cmd，启动zookeeper服务。
若启动失败，我遇到的，有几个种原因，详情请打开cmd文件，在endlocal之前添加 pause ，这样就不会闪退。
1、没配置java环境，在环境变量中，要JAVA_HOME这样配置变量，不能直接在path贴jdk路径。
2、在conf目录，将zoo_sample.cfg文件名修改成zoo.cfg。
第二步：
创建MAVEN JAVA工程，如下创建一个dubbo，一个接口模块，一个程序入口（SPRINGMVC）
3、interface项目，只要写一个类
package com.cwj.inter; import org.springframework.stereotype.Service; @Service public interface DemoService { public String sayHello(String name); }
pom.xml添加注释依赖
<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.cwj</groupId> <artifactId>interface</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>interface</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.0.2.RELEASE</version> </dependency> </dependencies> </project>
4、dubbo项目
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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.cwj</groupId> <artifactId>dubbo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>dubbo</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <springframework.version>3.2.4.RELEASE</springframework.version> <!-- Logging --> <slf4j.version>1.7.5</slf4j.version> <slf4j-log4j12.version>1.7.5</slf4j-log4j12.version> <log4j.version>1.2.17</log4j.version> </properties> <dependencies> <!-- Logging with SLF4J --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j-log4j12.version}</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>com.101tec</groupId> <artifactId>zkclient</artifactId> <version>0.3</version> </dependency> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.4.5</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.5.3</version> <scope>compile</scope> <exclusions> <exclusion> <artifactId>spring</artifactId> <groupId>org.springframework</groupId> </exclusion> </exclusions> </dependency> <!-- SPRING 解析XML--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>com.cwj</groupId> <artifactId>interface</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> </project>
创建DemoServiceImpl类，继承DemoService
package com.cwj.dubbo; import com.cwj.inter.DemoService; public class DemoServiceImpl implements DemoService{ public String sayHello(String name) { // TODO Auto-generated method stub System.out.println("hello:"+name); return "hello,"+name; } }
配置applicationProvider.xml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"> <!-- 提供方应用信息，用于计算依赖关系 --> <dubbo:application name="app-provider" /> <!-- 使用zookeeper注册中心暴露服务地址 --> <dubbo:registry address="zookeeper://127.0.0.1:2181" /> <!-- 用dubbo协议在20880端口暴露服务 --> <dubbo:protocol name="dubbo" port="20880" /> <!-- 声明需要暴露的服务接口 --> <dubbo:service interface="com.cwj.inter.DemoService" ref="demoService" /> <!-- 和本地bean一样实现服务 --> <bean id="demoService" class="com.cwj.dubbo.DemoServiceImpl" /> </beans>
在App类中添加启动方法
package com.cwj.dubbo; import java.io.IOException; import org.springframework.context.support.ClassPathXmlApplicationContext; /** * Hello world! * */ public class App { public static void main(String[] args) throws IOException { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationProvider.xml"); context.start(); System.out.println("-----dubbo开启-----"); System.in.read(); // 为保证服务一直开着，利用输入流的阻塞来模拟 } }
开心的话也可以添加log4j.properties配置文件，没有配置有警告。程序员眼里只有错误把。
log4j.rootLogger=INFO,Console,File log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.Target=System.out log4j.appender.Console.layout = org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n log4j.appender.File = org.apache.log4j.RollingFileAppender log4j.appender.File.File = logs/ssm.log log4j.appender.File.MaxFileSize = 10MB log4j.appender.File.Threshold = ALL log4j.appender.File.layout = org.apache.log4j.PatternLayout log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
运行APP的main方法就可以成功启动了。启动前要先打开zk服务。
第五步：protal项目，配置MVC
直接贴代码：
pom.xml

dubbo.xml
<?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"> <!-- 提供方应用信息，用于计算依赖关系 --> <dubbo:application name="app-customer" /> <!-- 使用zookeeper注册中心暴露服务地址 --> <dubbo:registry address="zookeeper://127.0.0.1:2181" /> <!-- 生成远程服务代理，可以和本地bean一样使用demoService --> <dubbo:reference id="demoService" interface="com.cwj.inter.DemoService" /> </beans>
spring-mvc.xml：
<?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:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <context:component-scan base-package="com.cwj.controller"></context:component-scan> <mvc:annotation-driven /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/"></property> <property name="suffix" value=".jsp"></property> </bean> <import resource="dubbo.xml"/> </beans>

comtroller
package com.cwj.controller; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.cwj.inter.DemoService; @Controller public class TestController { @Autowired private DemoService demoService; @RequestMapping("test") public String test(String name,HttpServletRequest request){ System.out.println("MVC WELCOME"); System.out.println(demoService.sayHello(name)); request.setAttribute("hello",demoService.sayHello(name)); return "test"; } }
启动项目成功连接，不想测试了。以后写博客尽量不贴代码。把自己遇到的问题给记录下来。 哪怕是几句话。
这个是一个过渡。加油。
