内容图文

一、zookeeper配置中心安装

1、下载安装包，zookeeper-3.4.6.tar.gz

2、解压安装包，修改配置文件

      参考zookeeper-3.4.6/conf/zoo_sample.cfg文件，同步录下建立zoo.cfg，配置如下：

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=E:\项目\zookeeper-3.4.6\data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

3、启动zk

点击E:\项目\zookeeper-3.4.6\bin\zkServer.cmd

socket connection from /192.168.1.100:54836

 二、dubboadmin监控中心的安装配置

1、下载tomcat安装运行

2、下载dubbo-admin-2.5.8.war到tomcat7 \ webapps目录下

3、修改dubbo.properties

重启tomcat、在编译后的文件中找到\WEB-INF文件夹下的dubbo.properties文件，然后进行配置，默认属性配置如下：

dubbo.registry.address=zookeeper://192.168.1.100:2181
dubbo.admin.root.password=root
dubbo.admin.guest.password=guest

4、验证dubbo-admin

重启zk、tomcat、访问：http://192.168.1.100:8080/dubbo-admin-2.5.8  ，进入监控中心的管理界面（默认管理员账户密码为：root，root）

三、dubbo代码示例

1、公共接口service

package com.dubbo.demo.api;

public interface DemoRpcService {

    /**
     * 测试方法
     * @return
     */
    String getUserName(String uid);
}

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<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>dubbo.demo</groupId>
    <artifactId>dubbo-api</artifactId>
    <version>1.0-SNAPSHOT</version>
</project>

2、生产者代码

package com.dubbo.demo;
import com.dubbo.demo.api.DemoRpcService;
public class DemoRpcServiceImpl implements DemoRpcService {


    public String getUserName(String uid) {
        System.out.println("接收入参："+uid);
        return "小明";
    }
}

启动代码：

    public static void main(String[] args) throws IOException {
        ClassPathXmlApplicationContext context
                = new ClassPathXmlApplicationContext("classpath:dubbo-provider.xml");
        context.start();
        // 阻塞当前进程，否则程序会直接停止
        System.in.read();
    }

 

dubbo-provider.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

3、消费者代码

public static void main(String[] args) throws IOException {
    ClassPathXmlApplicationContext context
            = new ClassPathXmlApplicationContext("classpath:dubbo-consumer.xml");
    context.start();

    String useId = "123456";
    DemoRpcService demoService = (DemoRpcService) context.getBean("demoRpcService");
    System.out.println("收到结果"+demoService.getUserName(useId));

    // 阻塞当前进程，否则程序会直接停止
    System.in.read();
}

dubbo-consumer.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">

    <dubbo:application name="dubbo-demo-provider"/>

    <!--dubbo注册地址-->
    <dubbo:registry address="zookeeper://192.168.1.100:2181"/>

    <!--接口引用-->
    <dubbo:reference interface="com.dubbo.demo.api.DemoRpcService" id="demoRpcService"/>
</beans>

            </plugin>
        </plugins>
    </build>

</project>

4、运行测试

先启动生产者、再启动消费者

log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
接收入参：123456
log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
