配置spring-mvc + simple-spring-memcached
jopen
8年前
运行环境：spring3.2.1 + simple-spring-memcached3.1.0（以下简称SSM）
1. 所需jar包，spring的包到spring官网下载，ssm所需包在这里下载，我下载的是3.1.0版本
注：解压simple-spring-memcached-3.1.0-dist.zip，复制lib目录中所有jar到工程lib 中，如果有相同的jar，保留版本高的，删除版本低的。复制dist目录中除了带有test的之外所有jar到工程的lib中。最终lib包如下：
2. 配置项目的web.xml文件，因为本人项目用的是spring-mvc，所以代码如下：

3. spring配置文件如下
注：需要解压simple-spring-memcached-3.1.0.jar，找到simplesm-context.xml放到src目录下

4. Controller 类文件
package com.dsideal.sys.action; import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import com.dsideal.sys.bean.SysLoginPersonBean; import com.dsideal.sys.service.ISysMemcachedTestService; @Controller public class SysLoginpersonController{ @Resource private ISysMemcachedTestService iSysMemcachedTestService; /** * <p>功能:登录</p> * @author 周枫 * @date 2013-3-7 * @param * @return void */ @RequestMapping(value="/login",method=RequestMethod.POST) public void login(HttpServletRequest request,HttpServletResponse response,@RequestParam("yzm") String yzm,SysLoginPersonBean loginPerson) { try { //save person_id to memcached //loginPerson.setPerson_id("8BEFBA28-627D-4A37-BAF9-E33FC0F44169"); //iSysMemcachedTestService.saveLoginPerson(loginPerson); //get person_id from memcached // SysLoginPersonBean lpBean = new SysLoginPersonBean(); // lpBean = iSysMemcachedTestService.getByPersonId("8BEFBA28-627D-4A37-BAF9-E33FC0F44169"); // System.out.print(lpBean.getLogin_name()); //delete person_id from memcached iSysMemcachedTestService.deletePerson("8BEFBA28-627D-4A37-BAF9-E33FC0F44169"); } catch (Exception e) { e.printStackTrace(); } } }
5. service文件：
package com.dsideal.sys.service; import com.dsideal.sys.bean.SysLoginPersonBean; import com.google.code.ssm.api.ParameterDataUpdateContent; import com.google.code.ssm.api.ParameterValueKeyProvider; public interface ISysMemcachedTestService { public void saveLoginPerson(SysLoginPersonBean lpBean); public SysLoginPersonBean getByPersonId(@ParameterValueKeyProvider String personId); public void updatePerson(@ParameterValueKeyProvider @ParameterDataUpdateContent SysLoginPersonBean lpBean); public void deletePerson(@ParameterValueKeyProvider String personId); }
6. serviceimpl文件：
解：组件所提供的切入点主要包括以下几种：
ReadThroughSingleCache、ReadThroughMultiCache、ReadThroughAssignCache
当遇到查询方法声明这些切入点时，组件首先会从缓存中读取数据，取到数据则跳过查询方法，直接返回。
取不到数据在执行查询方法，并将查询结果放入缓存，以便下一次获取。
InvalidateSingleCache、InvalidateMultiCache、InvalidateAssignCache
当遇到删除方法声明这些切入点时，组件会删除缓存中的对应实体
UpdateSingleCache、UpdateMultiCache、UpdateAssignCache
当遇到更新方法声明这些切入点是，组件会更新缓存中对应的实体，以便下次从缓存中读取出的数据状态是最新的
package com.dsideal.sys.service.impl; import java.util.HashMap; import java.util.Map; import org.apache.commons.collections.map.HashedMap; import org.springframework.stereotype.Service; import com.dsideal.sys.bean.SysLoginPersonBean; import com.dsideal.sys.service.ISysMemcachedTestService; import com.google.code.ssm.api.InvalidateSingleCache; import com.google.code.ssm.api.ParameterDataUpdateContent; import com.google.code.ssm.api.ParameterValueKeyProvider; import com.google.code.ssm.api.ReadThroughSingleCache; import com.google.code.ssm.api.UpdateSingleCache; @Service public class SysMemcachedTestServiceImpl implements ISysMemcachedTestService { private static final String NAMESPACE = "com.dsideal.sys.service.impl"; private Map<String,SysLoginPersonBean> person = new HashMap<String,SysLoginPersonBean>(); @Override public void saveLoginPerson(SysLoginPersonBean lpBean) { person.put(lpBean.getPerson_id(), lpBean); } /** * ReadThroughSingleCache、ReadThroughMultiCache、ReadThroughAssignCache 当遇到查询方法声明这些切入点时，组件首先会从缓存中读取数据，取到数据则跳过查询方法，直接返回。 取不到数据在执行查询方法，并将查询结果放入缓存，以便下一次获取 */ @Override @ReadThroughSingleCache(namespace = NAMESPACE, expiration = 600) public SysLoginPersonBean getByPersonId(@ParameterValueKeyProvider String personId) { System.out.println(personId); return person.get(personId); } @Override @UpdateSingleCache(namespace = NAMESPACE, expiration = 600) public void updatePerson(@ParameterValueKeyProvider @ParameterDataUpdateContent SysLoginPersonBean lpBean) { person.put(lpBean.getPerson_id(), lpBean); } @Override @InvalidateSingleCache(namespace = NAMESPACE) public void deletePerson(@ParameterValueKeyProvider String personId) { person.remove(personId); } }
7. bean类
注：这里bean一定要序列化，否则不能存入memcached
package com.dsideal.sys.bean; import java.io.Serializable; import com.google.code.ssm.api.CacheKeyMethod; @SuppressWarnings("serial") public class SysLoginPersonBean implements Serializable{ private String person_id; private String login_name; private String login_pwd; private int b_use; private int identity_id; private int bureau_id; private String real_name; @CacheKeyMethod public String getPerson_id() { return person_id; } public void setPerson_id(String person_id) { this.person_id = person_id; } public String getLogin_name() { return login_name; } public void setLogin_name(String login_name) { this.login_name = login_name; } public String getLogin_pwd() { return login_pwd; } public void setLogin_pwd(String login_pwd) { this.login_pwd = login_pwd; } public int getB_use() { return b_use; } public void setB_use(int b_use) { this.b_use = b_use; } public int getIdentity_id() { return identity_id; } public void setIdentity_id(int identity_id) { this.identity_id = identity_id; } public int getBureau_id() { return bureau_id; } public void setBureau_id(int bureau_id) { this.bureau_id = bureau_id; } public String getReal_name() { return real_name; } public void setReal_name(String real_name) { this.real_name = real_name; } public SysLoginPersonBean() { } public SysLoginPersonBean(String person_id,String login_name,String login_pwd,int b_use,int identity_id,int bureau_id,String real_name) { this.person_id = person_id; this.login_name = login_name; this.login_pwd = login_pwd; this.b_use = b_use; this.identity_id = identity_id; this.bureau_id = bureau_id; this.real_name = real_name; } }

具体测试方法，我已经写在controller里面了，需要分开执行测试，也可以参照本人之前写的博客，原生态的memcached第二种测试方法进行测试，具体链接为
