Dubbo+SpringMVC工程建立详解（附工程文件）

时间  2020-11-16 标签 java git github web 算法 spring 数据库 apache api 缓存

Dubbo出现的目的是为了应对如今高并发，高数据量请求的问题。目前的垂直应用架构已经没法知足如今大数据的冲击，SOA就应运而生，而Dubbo在国内使用的仍是比较多，稳定性也比较不错。java

架构

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。git

调用关系说明：

  1. 服务容器负责启动，加载，运行服务提供者。
  2. 服务提供者在启动时，向注册中心注册本身提供的服务。
  3. 服务消费者在启动时，向注册中心订阅本身所需的服务。
  4. 注册中心返回服务提供者地址列表给消费者，若是有变动，注册中心将基于长链接推送变动数据给消费者。
  5. 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，若是调用失败，再选另外一台调用。
  6. 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：github

注册中心负责服务地址的注册与查找，至关于目录服务，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web

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，并以报表展现算法

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spring

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数据库

注册中心，服务提供者，服务消费者三者之间均为长链接，监控中心除外apache

注册中心经过长链接感知服务提供者的存在，服务提供者宕机，注册中心将当即推送事件通知消费者api

注册中心和监控中心所有宕机，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缓存

注册中心和监控中心都是可选的，服务消费者能够直连服务提供者

(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，注册中心仍能经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，将自动切换到另外一台

注册中心所有宕掉后，服务提供者和服务消费者仍能经过本地缓存通信

服务提供者无状态，任意一台宕掉后，不影响使用

服务提供者所有宕掉后，服务消费者应用将没法使用，并没有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，可动态增长机器部署实例，全部客户端将自动发现新的注册中心

服务提供者无状态，可动态增长机器部署实例，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，须要实现动态部署，进行流动计算，现有分布式服务架构不会带来阻力：

能够得出，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仍是能够根据本地缓存进行沟通。 而且注册中心不是请求转发中心，因此压力是比较小的。

搭建Dubbo工程

一、ZooKeeper的配置安装

http://blog.csdn.net/u013142781/article/details/50395650

二、Dubbo-admin配置安装

http://blog.csdn.net/u013142781/article/details/50396621

三、工程API工程建立

API

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;
	};

}

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) {

        System.out.println(testService.getName());
        try {
            System.in.read();
        } catch (IOException e) {
            e.printStackTrace();
        }  
 
    }
}

六、运行测试

  1. 运行zookeeper，双击zkServer.cmd

  2. 运行dubbo-admin，双击Tomcat7w.exe，点击start

  3. 在eclipse中用tomcat运行服务提供者，可能存在超时，配置tomcat的timeout配置就能够了

  4. 在eclipse中用tomcat运行服务消费者

  5. 消费者工程的ConsumerServiceTest下，右键

就能够查看是否成功

正常结果：
