Spring与Redis整合

commons-lang3-3.1.jar

spring-data-commons-1.11.0.jar

spring-data-redis-1.6.1.jar

jedis-2.6.0.jar

spring-XX-4.0.6.jar

在spring的beans.xml中添加:

    <!-- 对象池 -->
    <bean id="jedisPoolConfig" 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>  

    <!-- 工厂实现 -->  
    <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">  
        <property name="hostName" value="${redis.host}" />  
        <property name="port" value="${redis.port}" />   
        <!-- <property name="password" value="${redis.pass}" />  -->  
        <property name="poolConfig" ref="jedisPoolConfig" />  
    </bean>  

    <!-- 模板类 --> 
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">  
        <property name="connectionFactory" ref="jedisConnectionFactory"/>
        <property name="keySerializer">
        	<bean class="org.springframework.data.redis.serializer.StringRedisSerializer"></bean>
        </property>
        <property name="valueSerializer"> <!-- default:JdkSerializationRedisSerializer -->
        	<bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"></bean>
        </property>
    </bean>

service实现层：

package com.edus.service.impl.demo;

import java.io.Serializable;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;

import javax.annotation.Resource;

import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

import com.edus.entity.Book;
import com.edus.service.demo.IRedisDemoService;

@Service("redisDemoService")
public class RedisDemoServiceImpl implements IRedisDemoService {

	@Resource
    private RedisTemplate<Serializable, Serializable> redisTemplate;

	private static String PREFIX_USER = "book:";
	
	
	@Override
	public void delBookInRedis(Integer id) {
		redisTemplate.opsForHash().delete(PREFIX_USER+id, id);
	}

	@Override
	public Book getBookFromRedis(final Integer id) {
//		redisTemplate.multi();
//		redisTemplate.opsForHash().put(PREFIX_USER+id, "id", id);
		Book book = (Book)redisTemplate.opsForHash().get(PREFIX_USER+id, id);
//		System.out.println(book);
//		redisTemplate.exec();
		return book;
	}

	@Override
	public void saveOrUpdateBookInRedis(final Book book) {
//		System.out.println("1xxxx="+redisTemplate.getConnectionFactory().getClass().getName());

		//开启事务
//		redisTemplate.multi();
		redisTemplate.opsForHash().put(PREFIX_USER+book.getId(), book.getId(), book);
//		redisTemplate.exec();
		
		
	}

	@Override
	public Set<Book> findBookListInRedis(Map<String, Object> args) {
		Set<Serializable> keySet = redisTemplate.keys(PREFIX_USER+"*");
		Set<Book> resultSet = new HashSet<Book>();
		for(Object key : keySet) {
			Integer id = Integer.parseInt(key.toString().split(":")[1]);
        	Book book = getBookFromRedis(id);
        	resultSet.add(book);
			System.out.println(book);
		}
		return resultSet;
	}
    
}
