zookeeper+dubbo和spring的整合

  搭建zookeeper之后，启动本地zookeeper服务。具体教程可参考：http://blog.csdn.net/hh12211221/article/details/76849717

创建maven项目

http://write.blog.csdn.net/postedit

• bookserviceImpl：java项目，作为serviceImpl和dao层的提供者；

• bookstoreapi：java项目，存放公共接口（service是serviceImpl的接口）及实体层，该项目均被其余两个项目依赖；

• bookStore：web项目，存放controller和页面。

bookstoreapi项目

bookstoreapi项目的目录结构为

启动服务

   加载Spring的相关配置，启动服务（或者将项目建为web项目，然后在web.xml中配置好sprin的启动，然后扔到tomcat中即可提供服务）

package com.book.main;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Main {public static void main(String[] args) {ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"application-provider.xml", "applicationContext-restTemplate.xml", "applicationContext.xml" });System.out.println("服务启动");context.start();}}

BookController.java

package com.book.controllers;import java.util.ArrayList;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.data.mongodb.core.MongoTemplate;import org.springframework.data.mongodb.core.aggregation.Aggregation;import org.springframework.data.mongodb.core.query.Criteria;import org.springframework.data.mongodb.core.query.Query;import org.springframework.stereotype.Controller;import org.springframework.web.client.RestTemplate;import com.book.book.model.Book;import com.book.book.service.BookService;import com.book.demo.service.DemoService;import net.paoding.rose.web.annotation.Param;import net.paoding.rose.web.annotation.Path;import net.paoding.rose.web.annotation.rest.Get;@Controller@Path("/")public class BookController {@AutowiredBookService bookService;@AutowiredMongoTemplate mongoTemplate;@AutowiredRestTemplate restTemplate;@AutowiredDemoService demoService;@Get("findAllBooks")public String FindAll() {String url = "http://yz4.chaoxing.com/common/appindex?companyId=1385";//String result = restTemplate.getForObject(url, String.class);//System.out.println(result);String bookList = bookService.FindAll();return "@" + bookList;}@Get("getByName")public String getByName(@Param("name") String name) {String bookList = bookService.getByName(name);return "@" + bookList;}@Get("getByAuthor")public String getByAuthor(@Param("author") String author) {String bookList = bookService.getByAuthor(author);return "@" + bookList;}@Get("getById")public String getById(String id) {String bookList = bookService.getById(id);return "@" + bookList;}}

Spring配置

   通过spring配置引用远程服务，配置如下。

<?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"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans          http://www.springframework.org/schema/beans/spring-beans.xsd          http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context.xsd        http://code.alibabatech.com/schema/dubbo          http://code.alibabatech.com/schema/dubbo/dubbo.xsd          "><!-- 消费方应用名，用于计算以来关系，不是匹配条件，不需要与提供方一样 --><dubbo:application name="bookStore" /><dubbo:registry protocol="zookeeper" address="127.0.0.1"port="2181" timeout="100000" /><!-- 生成远程服务代理，可以像使用本地bean一样使用demoService --><dubbo:reference id="demoService" interface="com.book.demo.service.DemoService"protocol="dubbo" timeout="100000" url="dubbo://192.168.1.230:20880" /><dubbo:reference id="userService" interface="com.book.user.service.UserService"protocol="dubbo" timeout="100000" url="dubbo://192.168.1.230:20880" /><dubbo:reference id="bookService" interface="com.book.book.service.BookService"protocol="dubbo" timeout="100000" url="dubbo://192.168.1.230:20880" /></beans>

启动服务，运行项目即可！至此zookeeper、dubbo和springmvc的整合结束。在项目中使用到rose框架、restTemplate、mysql、mongodb数据库的配置。详细代码可参考：http://download.csdn.net/download/hh12211221/9957332
