环境:
MAVEN+SPRING+MYBATIS+MYSQL+REDIS
1 pom.xml文件下载依赖:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.7.1.RELEASE</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.8.1</version>
</dependency>
2 配置spring.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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
xmlns:task="http://www.springframework.org/schema/task" xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/tx

">
<context:annotation-config />
<context:property-placeholder
ignore-unresolvable="true"
location="classpath*:/base.properties,classpath:redis.properties" />
<context:component-scan base-package="com.lping">
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
<context:exclude-filter type="annotation"
expression="org.springframework.web.bind.annotation.ControllerAdvice" />
</context:component-scan>
<import resource="redis-config.xml" />
3 配置redis-config.xml
注:redis-config.xml在spring.xml文件中配置<import resource="redis-config.xml" />
,
redis-config.xml配置如下:
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
xmlns:task="http://www.springframework.org/schema/task" xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd

<!--(1)如果你有多个数据源需要通过<context:property-placeholder管理,且不愿意放在一个配置文件里,那么一定要加上ignore-unresolvable=“true"-->
<!--(2)注意新版的(具体从哪个版本开始不清楚,有兴趣可以查一下)JedisPoolConfig的property name,不是maxActive而是maxTotal,而且没有maxWait属性,建议看一下Jedis源码。-->
<!-- redis连接池 -->
<bean id="jedisConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxTotal" value="${redis.maxActive}"></property>
<property name="maxIdle" value="${redis.maxIdle}"></property>
<property name="maxWaitMillis" value="${redis.maxWait}"></property>
<property name="testOnBorrow" value="${redis.testOnBorrow}"></property>
</bean>
<!-- redis连接工厂 -->
<bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<property name="hostName" value="${redis.host}"></property>
<property name="port" value="${redis.port}"></property>
<property name="password" value="${redis.password}"></property>
<property name="poolConfig" ref="jedisConfig"></property>
</bean>
<!-- redis操作模板,这里采用尽量面向对象的模板 -->
<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="connectionFactory"/>
<!-- 如果不配置Serializer,那么存储的时候只能使用String,如果用对象类型存储,那么会提示错误 can't cast to String!!!-->
<property name="keySerializer">
<bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
</property>
<property name="valueSerializer">
<bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>
</property>
<!--开启事务-->
<property name="enableTransactionSupport" value="true"/>
</bean>
</beans>
4 redis.properties配置如下
redis.properties在spring.xml配置加载
redis.maxActive=600
redis.maxIdle=300
redis.maxWait=1000
redis.testOnBorrow=true
# 所在服务器IP
redis.host=139.198.126.229
# 端口号
redis.port=6479
# 密码
redis.password=hesvit
5 RedisUtil.java 使用RedisTemplate
package com.lping.common.util;
import java.util.List;
import java.util.Map;
import java.util.Set;
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.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
public class RedisUtil {
private RedisTemplate<String,Object> redisTemplate;
public RedisUtil(RedisTemplate<String,Object> redisTemplate) {
// RedisSerializer解决数据库乱码问题
RedisSerializer stringSerializer = new StringRedisSerializer();
redisTemplate.setKeySerializer(stringSerializer);
redisTemplate.setValueSerializer(stringSerializer);
redisTemplate.setHashKeySerializer(stringSerializer);
redisTemplate.setHashValueSerializer(stringSerializer);
this.redisTemplate = redisTemplate;
}
@SuppressWarnings({ "rawtypes", "unchecked" })
public void set(String key, Object value) {
ValueOperations valueOperations = redisTemplate.opsForValue();
valueOperations.set(key, value);
}
public Object get(String key) {
return redisTemplate.opsForValue().get(key);
}
@SuppressWarnings({ "rawtypes", "unchecked" })
public void setList(String key, List<Object> value) {
ListOperations listOperations = redisTemplate.opsForList();
listOperations.leftPush(key, value);
}
public Object getList(String key) {
return redisTemplate.opsForList().leftPop(key);
}
public void setSet(String key, Set<Object> value) {
SetOperations setOperations = redisTemplate.opsForSet();
setOperations.add(key, value);
}
public Object getSet(String key) {
return redisTemplate.opsForSet().members(key);
}
@SuppressWarnings("unchecked")
public void setHash(String key, Map<String, Object> value) {
HashOperations hashOperations = redisTemplate.opsForHash();
hashOperations.putAll(key, value);
}
public Object getHash(String key) {
return redisTemplate.opsForHash().entries(key);
}
public void del(String key) {
redisTemplate.delete(key);
}
}
6 测试
我是直接在controller中写个方法测试了,你们可以用Junit或其他方式
@Controller
@Scope
@RequestMapping("/lp/test")
public class RedisTestController
{
// 注意,这里不要用@Autowired注解,我也不理解,可以百度一下
@Resource
private RedisTemplate<String, Object> redisTemplate;
@ResponseBody
@RequestMapping(value="/redisTest.do",method=RequestMethod.POST)
public void redisTest (HttpServletRequest request,HttpServletResponse response) {
RedisUtil util = new RedisUtil(redisTemplate);
String key = "aaa20180709";
util.set(key, "aaa111");
String value = (String) util.get(key);
logger.info(value);
util.del(key);
}
}
