dependencies 步骤3建立使用者类别 创建一个新的用户类。 package com.otv.user;import java.io.Serializable;/*** User Bean** author onlinetechvision.com* since 24 Feb 2012* version 1.0.0**/
public class User implements Serializable {private long id;private String name;private String surname;/*** Get User Id** return long id*/public long getId() {return id;}/*** Set User Id** param long id*/public void setId(long id) {this.id id;}/*** Get User Name** return long id*/public String getName() {return name;}/*** Set User Name** param String name*/public void setName(String name) {this.name name;}/*** Get User Surname** return long id*/public String getSurname() {return surname;}/*** Set User Surname** param String surname*/public void setSurname(String surname) {this.surname surname;}Overridepublic String toString() {StringBuilder strBuilder new StringBuilder();strBuilder.append(Id : ).append(getId());strBuilder.append(, Name : ).append(getName());strBuilder.append(, Surname : ).append(getSurname());return strBuilder.toString();}

public interface IHttpUserService {/*** Add User** param User user* return boolean response of the method*/public boolean addUser(User user);/*** Delete User** param User user* return boolean response of the method*/public boolean deleteUser(User user);/*** Get User List** return List user list*/public ListUser getUserList();} 步骤7创建HttpUserService类 HttpUserService类是通过实现IHttpUserService接口创建的。 package com.otv.http.server;import java.util.ArrayList;
import java.util.List;
import org.apache.log4j.Logger;import com.otv.cache.service.ICacheService;
import com.otv.user.User;/*** Http User Service Implementation** author onlinetechvision.com* since 10 Mar 2012* version 1.0.0**/
public class HttpUserService implements IHttpUserService {private static Logger logger Logger.getLogger(HttpUserService.class);//Remote Cache Service is injected...ICacheService cacheService;/*** Add User** param User user* return boolean response of the method*/public boolean addUser(User user) {getCacheService().getUserMap().put(user.getId(), user);logger.debug(User has been added to cache. User : getCacheService().getUserMap().get(user.getId()));return true;}/*** Delete User** param User user* return boolean response of the method*/public boolean deleteUser(User user) {getCacheService().getUserMap().remove(user.getId());logger.debug(User has been deleted from cache. User : user);return true;}/*** Get User List** return List user list*/public ListUser getUserList() {ListUser list new ArrayListUser();list.addAll(getCacheService().getUserMap().values());logger.debug(User List : list);return list;}/*** Get Remote Cache Service** return ICacheService Remote Cache Service*/public ICacheService getCacheService() {return cacheService;}/*** Set Remote Cache Service** param ICacheService Remote Cache Service*/public void setCacheService(ICacheService cacheService) {this.cacheService cacheService;}} 步骤8创建HttpUserService-servlet.xml HttpUserService应用程序上下文如下所示。 该xml必须命名为your_servlet_name-servlet.xml beans xmlnshttp://www.springframework.org/schema/beansxmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexmlns:utilhttp://www.springframework.org/schema/utilxsi:schemaLocationhttp://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/utilhttp://www.springframework.org/schema/util/spring-util-3.0.xsd!-- User Map Declaration --bean idUserMap classjava.util.concurrent.ConcurrentHashMap /!-- Cache Service Declaration --bean idCacheService classcom.otv.cache.service.CacheServiceproperty nameuserMap refUserMap//bean !-- Http User Service Bean Declaration --bean idHttpUserService classcom.otv.http.server.HttpUserService property namecacheService refCacheService//bean!-- Http Invoker Service Declaration --bean idHttpUserServiceExporter classorg.springframework.remoting.httpinvoker.HttpInvokerServiceExporter!-- service represents Service Impl --property nameservice refHttpUserService/!-- serviceInterface represents Http Service Interface which is exposed --property nameserviceInterface valuecom.otv.http.server.IHttpUserService//bean!-- Mapping configurations from URLs to request handler beans --bean idurlMapping classorg.springframework.web.servlet.handler.SimpleUrlHandlerMappingproperty namemappingspropsprop key/HttpUserServiceHttpUserServiceExporter/prop/props/property/bean/beans 步骤9创建web.xml web.xml的配置如下 ?xml version1.0 encodingUTF-8?
