]]>dubbohttp://www.blogjava.net/fanjs2000/archive/2016/05/04/430339.html猪眼睛猪眼睛Wed, 04 May 2016 09:03:00 GMThttp://www.blogjava.net/fanjs2000/archive/2016/05/04/430339.htmldubbo是阿里巴巴的框架，主要有4部分组成，1 服务台提供方， 2 服务注册方 3 服务消费分 4 监控部分

1. 注册方一般用zookeeper, 先下载安装，启动zkservece.cmd 会报错，需要修改配置文件 zoo.cfg. 路径中conf/下，，没有自己加一个。
正常启动

2. 编写一个服务器端, 创建maven项目

pom.xml文件

<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">

        </repository>
    </repositories>   
    
</project>

config/applicationProvider.xml  配置文件，里面定义了注册的bean, 和zookeeper的地址
<?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="hello-world" />
    <!-- 注册地址 -->
     <dubbo:registry address="zookeeper://localhost:2181" />
     <dubbo:protocol name="dubbo" port="20880" />
        <!-- Service interface Concurrent Control -->
        <dubbo:service interface="cn.zto.service.IProcessData"    ref="demoService" executes="10" />
        <!-- designate implementation -->
        <bean id="demoService" class="cn.zto.service.impl.ProcessDataImpl" />
    </beans>
IProcessData定义接口及实现类
package cn.zto.service.impl;

import cn.zto.service.IProcessData;
public class ProcessDataImpl implements IProcessData {
public String hello(String name) {
    System.out.println(name);
    return "hello : " + name;
}}

package cn.zto.service;

public interface IProcessData {
    public String hello(String name);
}
启动服务
package cn.zto.app;

import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Main {
public static void main(String[] args) throws Exception {
     ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(    new String[] {
"config/applicationProvider.xml"
});
context.start();
System.out.println("按任意键退出");
System.in.read();
}}
运行起来。如下
log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
按任意键退出



下面再建一个client程序
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">

注册的接口类，和要服务器端的包路径一致

package cn.zto.service;

public interface IProcessData {
    public String hello(String name);
}

客户端的配置文件，接口定义及zookeeper的地址
<?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="consumer-of-helloworld-app" />
    <!-- 注册地址 -->
     <dubbo:registry address="zookeeper://localhost:2181"/>
     <dubbo:consumer timeout="5000" />
     <dubbo:reference id="demoService" interface="cn.zto.service.IProcessData"/>
</beans>

客户端启动
package cn.zto.consumer;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.zto.service.IProcessData;

public class ConsumerThd{
    
    
    
public void sayHello(){
ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(    
new String[] {"config/applicationProvider.xml"});
context.start();
IProcessData demoService=(IProcessData) context.getBean("demoService");
System.out.println(demoService.hello("world"));
}


public static void main(String args[]){
    new ConsumerThd().sayHello();
}



}


运行结果如下

log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
hello : world


这样就基本实现了dubbo的框架，很简单吧

1. pom 文件， 主要写依赖关系，
<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">

    <name>spring-boot-example</name>
    
    <parent>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-parent</artifactId>
       <version>1.3.3.RELEASE</version>
    </parent>
    
    <!-- Add typical dependencies for a web application -->
    
    <dependencies>
        <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        
        
        
    </dependencies>

    <repositories>
        <repository>
            <id>spring-snapshots</id>
            <url>http://repo.spring.io/libs-snapshot</url>
        </repository>
    </repositories>

    <pluginRepositories>
        <pluginRepository>
            <id>spring-snapshots</id>
            <url>http://repo.spring.io/libs-snapshot</url>
        </pluginRepository>
    </pluginRepositories>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

2. 然后就是提供的接口类UserController， 实体类User， 主要是几个注解
@RestController   l类同spring mvc 的@Controller
@RequestMapping   类同spring mvc

package two;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/user")

public class UserController {

    @RequestMapping("/hello")
    public User view(){
        
        User user=new User();
        user.setId((long)100);
        user.setName("fanjs");
        return user;
        
        
    }

package two;

public class User {
private Long id;
private String name;
public Long getId() {
    return id;
}
public void setId(Long id) {
    this.id = id;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}


3.  然后就是程序启动，这里不需要spring xml文件，完全依赖注解。
@EnableAutoConfiguration
@Configuration
@ComponentScan

package two;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan
@EnableAutoConfiguration


public class RunMain {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        SpringApplication.run(RunMain.class, args);
    }

}

4.  测试路径

http://localhost:8080/user/hello

{"id":100,"name":"fanjs"}
