ssm+redis整合-蒲公英云

一、首先eclipse搭建好Maven环境，如何不会搭建可以参考eclipse配置maven

二、搭建好SSM框架

三、在pom.xml中引入java里redis的依赖（jedis）

<!--spring-data-redis-->
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>1.1.0.RELEASE</version> 
</dependency>
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.1.0</version>
</dependency>

注意：若报以下错误，是因为Jedis版本与spring版本不适配的问题

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'connectionF
actory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: redis.clients.jedis.JedisShardInfo.se tTimeout(I)V Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'connectionFactory' defined in class path resource [applicationContext. xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: redis.clients.jedis.JedisShardInfo.setTimeout(I)V

经本人运行配置后
spring 3.24 、spring-data-redis1.1.0 、 Jedis 2.1.0 适配，如果还是报该错误，请到网上查找其他适配版本，本人也是调试了很多版本才配置成功。

四、在spring配置文件中配置reids
本人是在spring-mybatis.xml中加入配置，读者可以单独创建一个spring-redis.xml单独配置。

<!-- jedis -->
<!-- redis配置 -->
    <!-- redis连接池 -->
       <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
            <property name="maxIdle" value="300" />
            <property name="minIdle" value="100"></property>
            <!-- <property name="maxTotal" value="500" /> -->
            <property name="maxWait" value="3000" />
            <property name="testOnBorrow" value="true"/>
        </bean> 
        <!-- redis连接工厂 -->
      <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" destroy-method="destroy">          
             <property name="hostName" value="${redis.hostName}"></property> 
             <property name="port" value="${redis.port}"></property>
             <property name="password" value="${redis.password}"></property>  
              <property name="poolConfig" ref="jedisPoolConfig"></property>
        </bean> 
 <!-- redis操作模板，这里采用尽量面向对象的模板 -->
      <bean id="jedisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> 
             <property name="connectionFactory" ref="jedisConnectionFactory"></property>
              <property name="keySerializer"> 
        <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/> 
               </property> 
       <property name="hashKeySerializer"> 
        <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/> 
       </property> 
       <property name="valueSerializer"> 
        <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/> <!--JdkSerializationRedisSerializer -->
       </property> 
       <property name="hashValueSerializer"> 
        <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/> 
       </property> 
            <!-- <property name="enableTransactionSupport" value="true"></property> -->
         </bean>

五、创建redis工具类
RedisTemplateUtil.java

import java.util.List;
import java.util.Map;
import java.util.Set;
import javax.annotation.Resource;
import org.springframework.data.redis.core.HashOperations;
import org.springframework.data.redis.core.ListOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.SetOperations;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Service;
public class RedisTemplateUtil { 
    @Resource
    private RedisTemplate<String, Object> redisTemplate;
    public void set(String key, Object value) { 
        ValueOperations<String, Object> valueOperations = redisTemplate
                .opsForValue();
        valueOperations.set(key, value);
    }
    public Object get(String key) { 
        return redisTemplate.opsForValue().get(key);
    }
    public void setList(String key, List<?> value) { 
        ListOperations<String, Object> listOperations = redisTemplate
                .opsForList();
        listOperations.leftPush(key, value);
    }
    public Object getList(String key) { 
        return redisTemplate.opsForList().leftPop(key);
    }
    public void setSet(String key, Set<?> value) { 
        SetOperations<String, Object> setOperations = redisTemplate.opsForSet();
        setOperations.add(key, value);
    }
    public Object getSet(String key) { 
        return redisTemplate.opsForSet().members(key);
    }
    public void setHash(String key, Map<String, ?> value) { 
        HashOperations<String, Object, Object> hashOperations = redisTemplate
                .opsForHash();
        hashOperations.putAll(key, value);
    }
    public Object getHash(String key) { 
        return redisTemplate.opsForHash().entries(key);
    }
    public void delete(String key) { 
        redisTemplate.delete(key);
    }
}

六、测试

@Resource
    private RedisTemplate<String, Object> redisTemplate;
    public void test(){ 
            RedisTemplateUtil redisTemplateUtil = new RedisTemplateUtil();//可以可不用
            List<Vt_Email> list = new ArrayList<Vt_Email>();
              for (int i = 0; i < 2; i++) { 
              Vt_Email vte = new Vt_Email();
              vte.setId(i);
              vte.setEmailName("generaterfq"+i);
              vte.setStatus("sent"+i);
              vte.setCreateBy("administrator"+i);
              vte.setRemark("");
              vte.setRfqNo("test"+i);*/
             list.add(vte);  
          redisTemplate.opsForList().leftPush("test2",vte.toString()); 
             }
        System.out.println(redisTemplate.opsForList().leftPop("test2"));
        List<Vt_Email> list2 = (List<Vt_Email>)      redisTemplate.opsForList().leftPop("test2");
            redisTemplate.delete("test2");
             redisTemplateUtil.setList("testlist", list);
          }
