springmvc整合redis架构搭建实例
新换环境,又有新东西可以学习了,哈皮! 抽空学习之余看了一下redis,个人对Springmvc的爱是忠贞不渝,所以整理了一下Springmvc整合redis的环境搭建.分享学习.
第一步: 创建maven项目:
实例pom.xml内容如下
<?xml version="1.0" encoding="UTF-8"?>

第二步:配置文件整合
Web.xml文件配置
<?xml version="1.0" encoding="UTF-8"?>

</web-app>
spring-context.xml内容
<?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:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">
<!-- 激活@Controller模式 -->
<mvc:annotation-driven />
<!-- 对包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 需要更改 -->
<context:component-scan base-package="com.pudp.bae.*" />
<!-- 引入同文件夹下的redis属性配置文件 -->

</beans>
redis-context.xml内容

<!-- scanner redis properties -->

Redis.properties文件内容
# Redis settings

redis.pass=

第三步:Springmvc对Redis的支持与实例应用.
实例对象
package com.pudp.bae.model;
import com.pudp.bae.base.BaseModel;
public class Member extends BaseModel{
/**
*
*/
private static final long serialVersionUID = -1959528436584592183L;
private String id;
private String nickname;
public Member(){}
public Member(String id, String nickname){
this.setId(id);
this.setNickname(nickname);
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getNickname() {
return nickname;
}
public void setNickname(String nickname) {
this.nickname = nickname;
}
}
Redis对象持久化操作
package com.pudp.bae.base; import java.io.Serializable; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.RedisSerializer; public abstract class RedisGeneratorDao<K extends Serializable, V extends Serializable> { @Autowired protected RedisTemplate<K,V> redisTemplate ; /** * 设置redisTemplate * @param redisTemplate the redisTemplate to set */
public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) { this.redisTemplate = redisTemplate; } /** * 获取 RedisSerializer * <br>------------------------------<br> */
protected RedisSerializer<String> getRedisSerializer() { return redisTemplate.getStringSerializer(); } }
package com.pudp.bae.base; import java.io.Serializable; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.RedisSerializer; public abstract class RedisGeneratorDao<K extends Serializable, V extends Serializable> { @Autowired protected RedisTemplate<K,V> redisTemplate ; /** * 设置redisTemplate * @param redisTemplate the redisTemplate to set */

Controller实现
package com.pudp.bae.controller; import java.util.HashMap; import java.util.Map; 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.ModelAttribute; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; import com.pudp.bae.base.BaseMultiController; import com.pudp.bae.model.Member; import com.pudp.bae.service.MemberService; @Controller @RequestMapping(value="/member") public class MemberController extends BaseMultiController{ @Resource(name="memberService") private MemberService memberService; public void setMemberService(MemberService memberService) { this.memberService = memberService; } @RequestMapping(value={"/add","/add.html"},method={RequestMethod.GET}) public ModelAndView add(HttpServletRequest request,HttpServletResponse response){ Map<String,Object> map = new HashMap<String, Object>(); return toView("member/add", map); } @RequestMapping(value={"/add","/add.html"},method={RequestMethod.POST}) public ModelAndView addMember(HttpServletRequest request,HttpServletResponse response, @ModelAttribute("member")Member member){ Map<String,Object> map = new HashMap<String, Object>(); System.out.println(member); map.put("message", "成功添加数据到库," + member); this.memberService.add(member); return toView("member/message", map); } @RequestMapping(value={"/{id:\\d+}/query","/{id:\\d+}/query.html"},method={RequestMethod.GET,RequestMethod.POST}) public ModelAndView queryMember(HttpServletRequest request,HttpServletResponse response, @PathVariable("id")String id){ Map<String,Object> map = new HashMap<String, Object>(); System.out.println(id); Member member = this.memberService.get(id); if(null!=member){ map.put("message", "查询Id=" + id + "的用户名为:" + member.getNickname()); }else{ map.put("message", "没有查询到与Id=" + id + "相关的数据"); } return toView("member/message", map); } @RequestMapping(value={"/{id:\\d+}/delete","/{id:\\d+}/delete.html"},method={RequestMethod.GET,RequestMethod.POST}) public ModelAndView deleteMember(HttpServletRequest request, HttpServletResponse response, @PathVariable("id")String id){ Map<String,Object> map = new HashMap<String, Object>(); try { this.memberService.delete(id); map.put("message", "删除Id为" + id +"的用户成功."); } catch (Exception e) { e.printStackTrace(); map.put("message", "删除Id为" + id +"的用户失败, "+e.getMessage()); } return toView("member/message", map); } }
