spring-data-redis 用法

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>>

一、jar包支持

<!-- redis支持 -->
		<dependency>
			<groupId>redis.clients</groupId>
			<artifactId>jedis</artifactId>
			<version>2.1.0</version>
		</dependency>

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

二、spring配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:aop="http://www.springframework.org/schema/aop" 
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:util="http://www.springframework.org/schema/util"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 
	http://www.springframework.org/schema/tx  http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 
	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd
	http://www.springframework.org/schema/context     
    http://www.springframework.org/schema/context/spring-context-3.0.xsd
    ">
  	
	
  	<!-- 配置Jredis连接池 -->
	<bean id="jedisPool" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxActive" value="1000" />
        <property name="maxIdle" value="50" />
        <property name="maxWait" value="5000" />
        <property name="testOnBorrow" value="true" />
    </bean>
	<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="poolConfig" ref="jedisPool" />
    </bean>

    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
    	<property name="connectionFactory" ref="jedisConnectionFactory"></property>
    </bean>
    <bean id="stringRedisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
    	<property name="connectionFactory" ref="jedisConnectionFactory"></property>
    </bean>
    
   
</beans>

三、单元测试配置

package com.iflashbuy.service.test.base;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;

@ContextConfiguration(locations = {"classpath:app-*.xml"}) 
@TransactionConfiguration(defaultRollback = true)
@RunWith(SpringJUnit4ClassRunner.class)
public class BaseTest extends AbstractTransactionalJUnit4SpringContextTests {
	
}

四、code

package com.iflashbuy.service.limanman;

import javax.inject.Inject;

import org.apache.commons.lang.StringUtils;
import org.junit.Assert;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;

import com.iflashbuy.service.product.dto.ProductDTO;
import com.iflashbuy.service.test.base.BaseTest;

public class RedisTest extends BaseTest {
	
	@Inject
	StringRedisTemplate strRedisTemplate;
	
	@Autowired
    private RedisTemplate<String, ProductDTO> redisTemplate;
    
    
	@Test
	public  void  testStringRedisTemplate() {
		strRedisTemplate.opsForValue().append("name", "fengshu");
		String name = strRedisTemplate.opsForValue().get("name");
		logger.info(name);
		Assert.assertTrue(StringUtils.isNotEmpty(name));
		strRedisTemplate.delete("name");
		name = strRedisTemplate.opsForValue().get("name");
		Assert.assertTrue(StringUtils.isEmpty(name));
		
	}
	
	
	@Test
	public void testRedisTemplate() {
		ProductDTO productDTO = new  ProductDTO();
		productDTO.setId("1");
		redisTemplate.opsForSet().add(productDTO.getId(), productDTO);
		productDTO = redisTemplate.opsForSet().pop("1");
		Assert.assertTrue("1".equals(productDTO.getId()));
	}
}

五、StringRedisTemplate和RedisTemplate区别

RedisTemplate支持pojo对象，StringRedisTemplate键值对操作的是字符串.
