Dubbo入门-简易配置

前言

想看分布式的东西好久了，目前的公司用不到，只能自己去网上找相关的，看到最多的Dubbo，于是趁着今天有时间自己照着一些教程自己配置了个基础的demo，顺便放出来。本文实例基于maven+spring+dubbo+zookeeper，开发工具为IDEA，系统环境为Windows10。

-2017.8.31

一、安装并启动zookeeper

此处用zookeeper作为dubbo的注册中心。

1.下载

本文使用的为zookeeper-3.4.10，下载地址为：http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.10/，其他版本可从http://mirrors.hust.edu.cn/apache/zookeeper/获取，其他下载地址可前往http://www.apache.org/dyn/closer.cgi/zookeeper/查阅。

2.安装

由于本身是绿色版，只需在磁盘中解压出来即可。另，zookeeper-3.4.10\conf目录下的zoo_sample.cfg文件需要复制一份并重命名为zoo.cfg。 zoo.cfg为zookeeper默认查找的配置文件名称。

3.配置

编辑zoo.cfg文件。

1
# The number of milliseconds of each tick
2
tickTime=2000
3
# The number of ticks that the initial
4
# synchronization phase can take
5
initLimit=10
6
# The number of ticks that can pass between
7
# sending a request and getting an acknowledgement
8
syncLimit=5
9
# the directory where the snapshot is stored.
10
# do not use /tmp for storage, /tmp here is just
11
# example sakes.
12
dataDir=/tmp/zookeeper
13
# the port at which the clients will connect
14
clientPort=2181
15
# the maximum number of client connections.
16
# increase this if you need to handle more clients
17
#maxClientCnxns=60
18
#
19
# Be sure to read the maintenance section of the
20
# administrator guide before turning on autopurge.
21
#
22
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
23
#
24
# The number of snapshots to retain in dataDir
25
#autopurge.snapRetainCount=3
26
# Purge task interval in hours
27
# Set to "0" to disable auto purge feature
28
#autopurge.purgeInterval=1

其中 [callout class=“info” title=“相关参数”]

tickTime：这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔，也就是每个 tickTime 时间就会发送一个心跳。
dataDir：顾名思义就是 Zookeeper 保存数据的目录，默认情况下，Zookeeper 将写数据的日志文件也保存在这个目录里。
clientPort：这个端口就是客户端连接 Zookeeper 服务器的端口，Zookeeper 会监听这个端口，接受客户端的访问请求。

[/callout] dataDir目录需改成你真实输出目录，其余的看个人喜好修改。

4.启动

进入zookeeper-3.4.10\bin目录下，根据个人系统启动项目，其中Windows下直接运行zkServer.cmd文件即可。其余可参考文末附录。启动成功后会停留在binding to port 处，如图：

二、创建对外提供服务的接口---dubbo-api

这是一个项目，也可以算是一个模块，因为提供者（provider）和消费者（consumer）都需要引入该模块。提供者对该接口的做具体实现，消费者通过该接口调用提供者的具体实现并获取结果。可以通过添加module或者将该项目打成jar的方式引入提供者与消费者项目中。该项目在本文被命名为dubbo-api。

1.接口TestService.java

1
package com.windcoder.dubbo.service;
2

3
/**
4
 * Description:
5
 * User: WindCoder
6
 * Date: 2017-08-30
7
 * Time: 14:39 下午
8
 */
9
public interface TestService {
10
    /**
11
     * 测试发消息
12
     * @param name
13
     * @return
14
     */
15
    public String sayHello(String name);
16
}

2.该项目的pom.xml配置

默认即可，类似如下，主要需要注意packaging应为jar。

1
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
2
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
3
  <modelVersion>4.0.0</modelVersion>
4
  <groupId>com.windcoder</groupId>
5
  <artifactId>dubbo-api</artifactId>
6
  <packaging>jar</packaging>
7
  <version>1.0-SNAPSHOT</version>
8
  <name>dubbo-api</name>
9
  <url>http://maven.apache.org</url>
10

11
  <properties>
12
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
13
  </properties>
14

15
  <dependencies>
16
    <dependency>
17
      <groupId>junit</groupId>
18
      <artifactId>junit</artifactId>
19
      <version>3.8.1</version>
20
      <scope>test</scope>
21
    </dependency>
22
  </dependencies>
23
  <build>
24
    <finalName>dubbo-api</finalName>
25
  </build>
26
</project>

三、创建服务提供者---dubbo-server

该项目用于对上面dubbo-api中定义的接口进行相关实现。记得开始所说，需要引入dubbo-api项目或其构建的jar包，否则会报无法找到TestService的错误。

1.具体实现类TestServiceImpl.java

1
package com.windcoder.dubboServer.service.impl;
2

3

4
import com.windcoder.dubbo.service.TestService;
5
import org.springframework.stereotype.Service;
6

7
/**
8
 * Description:
9
 * User: wind
10
 * Date: 2017-08-30
11
 * Time: 11:59 上午
12
 */
13
@Service("testService")
14
public class TestServiceImpl implements TestService {
15
    public String sayHello(String name) {
16
        return name + " service say hello Test service By windCoder.com!";
17
    }
18
}

2.该项目的pom.xml配置

4.dubbo.xml配置文档

此处用于dubbo提供者的配置，测试中该提供者实现了两个接口，为教程简洁，上面仅提了TestService接口：

</beans>

5.log4j.properties

由于不是主要内容，此处暂且省略介绍。

四、创建服务消费者---dubbo-consumer

该项目为调用远程服务的服务消费方。记得开始所说，需要引入dubbo-api项目或其构建的jar包，否则会报无法找到TestService的错误。

1.消费者类实现JSAPIController.java

（3）web.xml

在提供者的web.xml的基础上配置springMVC。 [toggle hide=“yes” title=“web.xml” color=""]

5.log4j.properties

由于不是主要内容，此处暂且省略介绍。

五、安装管理控制台

本身经过以上几步，一个简易程序便可运行了。但由于Zookeeper本身为命令窗口形式，无法很好的检测与管理相关接口等，dubbo官方则为我们提供了相应;de管理后台。

下载

从官方仓库下载所有源码文件即可，地址：https://github.com/alibaba/dubbo。

配置

对其中的dubbo-admin模块下的webapps/ROOT/WEB-INF/dubbo.properties文件进行修改。分别是zookeeper地址，root的登陆密码，guest的登陆密码：

1
dubbo.registry.address=zookeeper://127.0.0.1:2181
2
dubbo.admin.root.password=root
3
dubbo.admin.guest.password=guest

请根据实际情况修改，此处仅作参考。

启动

对其中的dubbo-admin模块进行打包，将生成的WAR包放到Tomcat中运行起来即可。或者本地测试也可以在idea中打开运行。最终可查看到如本文开头的界面。
