Dubbo+SpringMVC工程创建详解(附工程文件)
Dubbo出现的目的是为了应对现在高并发,高数据量请求的问题。目前的垂直应用架构已经无法满足现在大数据的冲击,SOA就应运而生,而Dubbo在国内使用的还是比较多,稳定性也比较不错。
架构
节点角色说明:
Provider: 暴露服务的服务提供方。
Consumer: 调用远程服务的服务消费方。
Registry: 服务注册与发现的注册中心。
Monitor: 统计服务的调用次调和调用时间的监控中心。
Container: 服务运行容器。
调用关系说明:
- 服务容器负责启动,加载,运行服务提供者。
- 服务提供者在启动时,向注册中心注册自己提供的服务。
- 服务消费者在启动时,向注册中心订阅自己所需的服务。
- 注册中心返回服务提供者地址列表给消费者,如果有变更,注册中心将基于长连接推送变更数据给消费者。
- 服务消费者,从提供者地址列表中,基于软负载均衡算法,选一台提供者进行调用,如果调用失败,再选另一台调用。
- 服务消费者和提供者,在内存中累计调用次数和调用时间,定时每分钟发送一次统计数据到监控中心。
(1) 连通性:
注册中心负责服务地址的注册与查找,相当于目录服务,服务提供者和消费者只在启动时与注册中心交互,注册中心不转发请求,压力较小
监控中心负责统计各服务调用次数,调用时间等,统计先在内存汇总后每分钟一次发送到监控中心服务器,并以报表展示
服务提供者向注册中心注册其提供的服务,并汇报调用时间到监控中心,此时间不包含网络开销
服务消费者向注册中心获取服务提供者地址列表,并根据负载算法直接调用提供者,同时汇报调用时间到监控中心,此时间包含网络开销
注册中心,服务提供者,服务消费者三者之间均为长连接,监控中心除外
注册中心通过长连接感知服务提供者的存在,服务提供者宕机,注册中心将立即推送事件通知消费者
注册中心和监控中心全部宕机,不影响已运行的提供者和消费者,消费者在本地缓存了提供者列表
注册中心和监控中心都是可选的,服务消费者可以直连服务提供者
(2) 健状性:
监控中心宕掉不影响使用,只是丢失部分采样数据
数据库宕掉后,注册中心仍能通过缓存提供服务列表查询,但不能注册新服务
注册中心对等集群,任意一台宕掉后,将自动切换到另一台
注册中心全部宕掉后,服务提供者和服务消费者仍能通过本地缓存通讯
服务提供者无状态,任意一台宕掉后,不影响使用
服务提供者全部宕掉后,服务消费者应用将无法使用,并无限次重连等待服务提供者恢复
(3) 伸缩性:
注册中心为对等集群,可动态增加机器部署实例,所有客户端将自动发现新的注册中心
服务提供者无状态,可动态增加机器部署实例,注册中心将推送新的服务提供者信息给消费者
(4) 升级性:
当服务集群规模进一步扩大,带动IT治理结构进一步升级,需要实现动态部署,进行流动计算,现有分布式服务架构不会带来阻力:
可以得出,注册中心若宕机,只要没有注册新的服务,服务提供者和消费者还是可以根据本地缓存进行沟通。
并且注册中心不是请求转发中心,所以压力是比较小的。
搭建Dubbo工程
1、ZooKeeper的配置安装
http://blog.csdn.net/u013142781/article/details/50395650
2、Dubbo-admin配置安装
http://blog.csdn.net/u013142781/article/details/50396621
3、工程API工程创建
工程使用Maven+SpringMVC的方式构建
ITestService.java
package com.gege.service;
public interface ITestService {
public String getName();
}
DubboInit.java
package com.gege.tool;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import org.apache.commons.lang.exception.ExceptionUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class DubboInit extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 8279515033200832L;
private Logger logger = (Logger) LoggerFactory.getLogger(DubboInit.class);
/**
* 启动dubbo容器
*/
public void init() throws ServletException {
try {
startApplicationContext();
} catch (Exception e) {
e.printStackTrace();
logger.error(ExceptionUtils.getFullStackTrace(e));
}
}
public static ApplicationContext applicationContext = null;
/**
* 启动spring容器
* @return
*/
public static ApplicationContext startApplicationContext() {
if (applicationContext == null) {
applicationContext = new ClassPathXmlApplicationContext("classpath*:applicationContext.xml");
}
return applicationContext;
};
}

同上
statics.properties
dubbo.gege.address=${dubbo.gege.address}
dubbo.gege.group=${dubbo.gege.group}
dubbo.gege.version=${dubbo.gege.version}
dubbo.gege.retries=0
dubbo.gege.timeout=10000
ConsumerServiceTest.java
package com.gege.service;
import java.io.IOException;
import org.apache.log4j.Logger;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class ConsumerServiceTest {
Logger logger=Logger.getLogger(ConsumerServiceTest.class);
public static void main(String[] args) {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
new String[] { "applicationContext.xml" });
context.start();
ITestService testService = (ITestService) context.getBean("testService");
System.out.println(testService.getName());
try {
System.in.read();
} catch (IOException e) {
e.printStackTrace();
}
}
}
6、运行测试
- 运行zookeeper,双击zkServer.cmd
- 运行dubbo-admin,双击Tomcat7w.exe,点击start
- 在eclipse中用tomcat运行服务提供者,可能存在超时,配置tomcat的timeout配置就可以了
- 在eclipse中用tomcat运行服务消费者
- 消费者工程的ConsumerServiceTest下,右键
就可以查看是否成功
正常结果:
gege
