一、创建maven项目

实例pom.xml内容如下

<?xml version="1.0" encoding="UTF-8"?>

            </resource>
        </resources>
    </build>
</project>

二、配置文件整合

2.1 Web.xml文件配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/context/spring-context.xml</param-value>
    </context-param>
    
    <!-- Spring字符集过滤器 -->
    <filter>
        <filter-name>SpringEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>

    </filter>
    <filter-mapping>
        <filter-name>SpringEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
    
    <servlet>
        <servlet-name>mvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
                 <param-name>contextConfigLocation</param-name>
                 <param-value>/WEB-INF/context/spring-mvc.xml</param-value>
         </init-param>
         <load-on-startup>2</load-on-startup>
    </servlet>
    
    <servlet-mapping>
        <servlet-name>mvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

</web-app>

2.2 spring-context.xml

<?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"

    <!-- 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 -->
    <import resource="redis-context.xml"/>

</beans>

2.3 redis-context.xml

<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:tx="http://www.springframework.org/schema/tx"

    <!-- scanner redis properties  --> 
    <context:property-placeholder location="/WEB-INF/property/redis.properties" />
    
    <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">  
        <property name="maxIdle" value="${redis.maxIdle}" />  
        <property name="maxActive" value="${redis.maxActive}" />  
        <property name="maxWait" value="${redis.maxWait}" />  
        <property name="testOnBorrow" value="${redis.testOnBorrow}" />  
    </bean>  
      
    <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"  
        p:host-name="${redis.host}" 
        p:port="${redis.port}" 
        p:password="${redis.pass}"  
        p:pool-config-ref="poolConfig"/>  
      
    <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">  
        <property name="connectionFactory"   ref="connectionFactory" />  
    </bean>      
     
</beans>

2.4 Redis.properties

# Redis settings
#redis.host=192.168.20.101
#redis.port=6380
#redis.pass=foobared
redis.host=127.0.0.1
redis.port=6379
redis.pass=
  
redis.maxIdle=300
redis.maxActive=600
redis.maxWait=1000
redis.testOnBorrow=true

三、Springmvc对Redis的支持与实例应用

3.1 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;
    }
    
}

3.2 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 
     */  
    public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) {  
        this.redisTemplate = redisTemplate;  
    }  
      
    /** 
     * 获取 RedisSerializer 
     * <br>------------------------------<br> 
     */  
    protected RedisSerializer<String> getRedisSerializer() {  
        return redisTemplate.getStringSerializer();  
    }  
    
}

3.3 redis对象操作

package com.pudp.bae.dao.redis;

import java.util.ArrayList;
import java.util.List;

import org.springframework.dao.DataAccessException;
import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.core.RedisCallback;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.stereotype.Repository;
import org.springframework.util.Assert;

import com.pudp.bae.base.RedisGeneratorDao;
import com.pudp.bae.model.Member;



@Repository(value="memberDao")
public class MemberDaoImpl extends RedisGeneratorDao<String,Member> implements MemberDao{

    
    /**
     * 添加对象
     */
    @Override
    public boolean add(final Member member) {  
        boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {  
            public Boolean doInRedis(RedisConnection connection)  
                    throws DataAccessException {  
                RedisSerializer<String> serializer = getRedisSerializer();  
                byte[] key  = serializer.serialize(member.getId());  
                byte[] name = serializer.serialize(member.getNickname());  
                return connection.setNX(key, name);  
            }  
        });  
        return result;  
    }  

    /**
     * 添加集合
     */
    @Override
    public boolean add(final List<Member> list) {
        Assert.notEmpty(list);  
        boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {  
            public Boolean doInRedis(RedisConnection connection)  
                    throws DataAccessException {  
                RedisSerializer<String> serializer = getRedisSerializer();  
                for (Member member : list) {  
                    byte[] key  = serializer.serialize(member.getId());  
                    byte[] name = serializer.serialize(member.getNickname());  
                    connection.setNX(key, name);  
                }  
                return true;  
            }  
        }, false, true);  
        return result; 
    }  
    
    /**
     * 删除对象 ,依赖key
     */
    public void delete(String key) {  
        List<String> list = new ArrayList<String>();  
        list.add(key);  
        delete(list);  
    }  
  
    /**
     * 删除集合 ,依赖key集合
     */
    public void delete(List<String> keys) {  
        redisTemplate.delete(keys);  
    }  
    
    /**
     * 修改对象 
     */
    public boolean update(final Member member) {  
        String key = member.getId();  
        if (get(key) == null) {  
            throw new NullPointerException("数据行不存在, key = " + key);  
        }  
        boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {  
            public Boolean doInRedis(RedisConnection connection)  
                    throws DataAccessException {  
                RedisSerializer<String> serializer = getRedisSerializer();  
                byte[] key  = serializer.serialize(member.getId());

                connection.set(key, name);  
                return true;  
            }  
        });  
        return result;  
    }  
    
    /**
     * 根据key获取对象
     */
    public Member get(final String keyId) {  
        Member result = redisTemplate.execute(new RedisCallback<Member>() {  
            public Member doInRedis(RedisConnection connection)  
                    throws DataAccessException {  
                RedisSerializer<String> serializer = getRedisSerializer();  
                byte[] key = serializer.serialize(keyId);

                if (value == null) {  
                    return null;  
                }  
                String nickname = serializer.deserialize(value);  
                return new Member(keyId, nickname);  
            }  
        });  
        return result;  
    }  

}

3.4 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})
