【Redis基础】SSH 中Spring-data-redis使用体验

1、项目中导入所需3个jar包

   commons-pool-2.2.jar

   jedis-2.3.1.jar

   spring-data-redis-1.3.4.relese.jar

2、新建redis配置文件redis.properties内容为

redis.host=127.0.0.1  #ipredis.port=6379     #端口redis.default.db=0redis.timeout=100000redis.maxActive=300redis.maxIdle=100redis.maxWait=1000redis.testOnBorrow=true 

3、新建spring配置redis的文件redis.xml，内容为

<?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: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-4.0.xsd"> <!-- 加载Reids属性配置文件 --><context:property-placeholderlocation="classpath:redis.properties" /><bean id="propertyConfigurerRedis"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="order" value="1" /><property name="ignoreUnresolvablePlaceholders" value="true" /><property name="systemPropertiesMode" value="1" /><property name="searchSystemEnvironment" value="true" /><property name="locations"><list><value>classpath:redis.properties</value></list></property></bean><!-- jedis pool配置 --><bean id="jedisPoolConfig"class="redis.clients.jedis.JedisPoolConfig"><property name="maxIdle" value="${redis.maxIdle}" /><property name="testOnBorrow" value="${redis.testOnBorrow}" /></bean><!-- spring data redis --><bean id="jedisConnectionFactory"class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"><property name="usePool" value="true"></property><property name="hostName" value="${redis.host}" /><property name="port" value="${redis.port}" /><property name="timeout" value="${redis.timeout}" /><property name="database" value="${redis.default.db}"></property><constructor-arg index="0" ref="jedisPoolConfig" /></bean><bean id="redisTemplate"class="org.springframework.data.redis.core.StringRedisTemplate"p:connectionFactory-ref="jedisConnectionFactory"p:keySerializer-ref="stringRedisSerializer"></bean><!--这个主要是解决用cmd查看数据时为了显示正常--><bean id="stringRedisSerializer"class="org.springframework.data.redis.serializer.StringRedisSerializer" /><!--配置一个基础类（之后的业务类继承于该类）、将redisTemplate注入 --><bean id="redisBase" abstract="true"><property name="template" ref="redisTemplate"/></bean><!-- 自动扫描 ： 加载构建bean，以便通过注解方式注册bean --><context:component-scan base-package="com.fudabdlwj.redisclient" /></beans> 

4、web配置文件中添加reids配置

<context-param>    <param-name>contextConfigLocation</param-name>    <param-value>     classpath:applicationContext.xml,     classpath:cxfservice.xml     classpath:redis.xml    </param-value>  </context-param>

5、编写接口，测试例子是网上找到的，做些点修改

package com.fudabdlwj.redisclient;public interface IRedisService<K, V> {         public void set(K key, V value, long expiredTime);    public V get(K key);    public void del(K key);         public Boolean check(K key,V value);       }

6、抽象类

package com.fudabdlwj.redisclient;import java.util.concurrent.TimeUnit;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.data.redis.core.BoundValueOperations;import org.springframework.data.redis.core.RedisTemplate;public abstract class AbstractRedisService<K, V> implements IRedisService<K, V> {    @Autowired    private RedisTemplate<K, V> redisTemplate;     public RedisTemplate<K, V> getRedisTemplate() {        return redisTemplate;    }     public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) {        this.redisTemplate = redisTemplate;    }       @Override    public void set(final K key, final V value, final long expiredTime) {        BoundValueOperations<K, V> valueOper = redisTemplate.boundValueOps(key);        if (expiredTime <= 0) {            valueOper.set(value);        } else {            valueOper.set(value, expiredTime, TimeUnit.MILLISECONDS);        }    }     @Override    public V get(final K key) {        BoundValueOperations<K, V> valueOper = redisTemplate.boundValueOps(key);        return valueOper.get();    }     @Override    public void del(K key) {        if (redisTemplate.hasKey(key)) {            redisTemplate.delete(key);        }    }    @Override    public Boolean check(K key,V value){     Boolean flag=false;     if (redisTemplate.hasKey(key)) {      if(value.equals(get(key))){       flag=true;      }     }     return flag;    } }

7、实现类

package com.fudabdlwj.redisclient;import org.springframework.stereotype.Service;@Service("redisService")public class RedisService extends AbstractRedisService<String, String> {}

8、测试

public static void main(String[] args) {   @SuppressWarnings("resource")    ApplicationContext factory=new ClassPathXmlApplicationContext("classpath:redis.xml");       RedisService rs= (RedisService) factory.getBean("redisService");  if(rs!=null){   System.out.println("RedisService : "+rs);   if(rs.check("lwj", "123456")){ //</span><span style="font-family: 微软雅黑;">lwj</span><span style="font-family: 微软雅黑;">已事先写进redis的数据</span><span style="font-family:微软雅黑;"></span><span style="font-family:微软雅黑;">    System.out.println("redis has contianed </span><span style="font-family: 微软雅黑;">lwj 123456</span><span style="font-family: 微软雅黑;">");</span><span style="font-family:微软雅黑;">    System.out.println("add one new key-value : lwj 1234567 expire 15000");    rs.set("lwj", "123456", 15000);   }else{    System.out.println("add one new key-value : lwj 123456 expire 15000");    rs.set("lwj", "1234567", 15000);   }       String value=rs.get("lwj");   System.out.println(value);}

结果

RedisService : com.fudabdlwj.redisclient.RedisService@2dafcbf 
redis has contianed lwj
add one new key-value : lwj 1234567 expire 15000 
1234567

通过redis-cli.exe查看对应数据写入成功，15000时间到达时lwj被清除。
