SpringBoot与Dubbo整合下篇

  (1)pom.xml引入相关依赖jar包,如下:

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.5.3</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.5</version>
            <exclusions>
                <exclusion>                
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-log4j12</artifactId>
                </exclusion>
                <exclusion>                
                    <groupId>log4j</groupId>
                    <artifactId>log4j</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.1</version>
        </dependency>

  (2)编写服务的接口以及实现类,如下:

package springboot.dao;

public interface DubboService {

    public String sayHello();
}

  接口实现类:

package springboot.dao.imp;
import org.springframework.stereotype.Service;
import springboot.dao.DubboService;

@Service("DubboService")
public class DubboServiceImp implements DubboService{

    @Override
    public String sayHello() {
        
        return "Hello Dubbo";
    }

}

  (3)在resources文件下建立服务方provider.xml配置文件,内容如下:

<?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">
    <!-- 服务应用名称 -->
    <dubbo:application name="provider"/>
    <!-- 使用zookeeper做为注册中心 -->
    <dubbo:registry  protocol="zookeeper" address="zookeeper://172.31.19.224:2181"/>
    <!-- ref中的值要跟服务实现类中的@Server的值一致 -->
    <dubbo:service interface="springboot.dao.DubboService" ref="DubboService"></dubbo:service>
</beans>

  (4)修改springboot启动类,启动时引入provider.xml文件,使用@ImportResource("classpath:provider.xml"),如下:

package springboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.ImportResource;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
@EnableCaching
@ImportResource("classpath:consumer.xml")
public class SpringbootApplication extends SpringBootServletInitializer{

    public static void main(String[] args) {
        SpringApplication.run(SpringbootApplication.class, args);
    }
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringbootApplication.class);
    }
}

  至此,服务方已经配置完毕了,我这里将代码发布到tomcat上。如果想在本地测试话,需要更改一下启动端口,因为后面消费方也需要启动。

  (5)接下来我们将服务接口.class文件(即上述的DubboService.class接口)打成jar包,(服务消费方在项目中需要导入该jar包才能调用服务),进入到DubboService.class目录下,启动控制台,输入:

  

  至此,dubbo服务方提供已经开发完毕!

  (6)接下来开发服务消费方,将上述jar包导入到项目中。如果是maven项目,还需要将jar继续打包,将上述jar包修改成DubboService-1.0.jar,输入如下命令:

mvn install:install-file -Dfile=DubboService-1.0.jar -DgroupId=dubboService -DartifactId=dubboService -Dversion=1.0 -Dpackaging=jar 

  结束后,会在本地仓库生成如下文件夹:

  

 (7)在resources文件下新建consumer.xml配置文件,如下:

<?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">
    <!-- 应用名称 -->
    <dubbo:application name="consumer" />
    <!-- zookeeper作为注册中心 -->
    <dubbo:registry  protocol="zookeeper" address="zookeeper://172.31.19.224:2181" />
    <!-- 生成远程服务代理 -->
    <dubbo:reference interface="springboot.dao.DubboService" id="dubboService"></dubbo:reference>
</beans>

  (8)在pom.xml中引入刚刚打包生成的jar包,如下:

 <dependency>
            <groupId>dubboService</groupId>
            <artifactId>dubboService</artifactId>
            <version>1.0</version>
  </dependency>

  (9)新建Controller,如下:

package springboot.web;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import springboot.dao.DubboService;


@RestController
public class HelloController {
    
    @Autowired
    private DubboService dubboService;

    @RequestMapping("/hello")
    public String hello(){
        return dubboService.sayHello();
    }
}

  (10)修改启动类,如下:

package springboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.ImportResource;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
@EnableCaching
@ImportResource("classpath:consumer.xml")
public class SpringbootApplication extends SpringBootServletInitializer{

    public static void main(String[] args) {
        SpringApplication.run(SpringbootApplication.class, args);
    }
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringbootApplication.class);
    }
}

  (11)测试验证,浏览器输入:http://localhost:8080/hello,显示如下:

    

  至此,springBoot与Dubbo整合完毕!过程中也遇到一些小问题,记录一下吧。

  (1)过程provider.xml,consumer.xml文件会报错,但是不影响项目运行,如下:Description Resource Path Location Type cvc-complex-type.2.4.c: The matching..........

           解决方法如下:http://blog.csdn.net/u010457406/article/details/50696390

  (2)项目没有报错,但是项目名出现了个红叉,百度搜了好多都不对,只有这个有效,地址如下:

  继续努力!
