redis作为web项目一个较好解决缓存问题的方案被大量运用,redis具体的概念在此不做详细介绍,本文介绍项目整合redis并且做一系列的操作
1:maven项目引入依赖
<!-- redis -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.7.0</version>
</dependency> <dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.5.0.RELEASE</version>
</dependency>
2:新建一个spring-redis.xml配置文件(其他的配置文件不做介绍)
<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd

<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig"></bean>
<bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="172.16.10.247" p:port="6379" p:password="" p:pool-config-ref="poolConfig"/>
<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="connectionFactory" />
<property name="keySerializer">
<bean
class="org.springframework.data.redis.serializer.StringRedisSerializer" />
</property>
<property name="valueSerializer">
<bean
class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
</property>
</bean>
</beans>
3:建一个测试类
@Autowired RedisTemplate redisTemplate;//自动注入
// String读写
redisTemplate.delete("myStr");
redisTemplate.opsForValue().set("myStr", "abc");
System.out.println(redisTemplate.opsForValue().get("myStr"));
System.out.println("---------------");
// List读写
redisTemplate.delete("myList");
redisTemplate.opsForList().rightPush("myList", "A");
redisTemplate.opsForList().rightPush("myList", "B");
redisTemplate.opsForList().leftPush("myList", "0");
List<String> listCache = redisTemplate.opsForList().range("myList", 0, -1);
for (String s : listCache) {
System.out.println(s);
}
System.out.println("---------------");
// Set读写
redisTemplate.delete("mySet");
redisTemplate.opsForSet().add("mySet", "A");
redisTemplate.opsForSet().add("mySet", "B");
redisTemplate.opsForSet().add("mySet", "C");
Set<String> setCache = redisTemplate.opsForSet().members("mySet");
for (String s : setCache) {
System.out.println(s);
}
System.out.println("---------------");
// Hash读写
redisTemplate.delete("myHash");
redisTemplate.opsForHash().put("myHash", "PEK", "北京");
redisTemplate.opsForHash().put("myHash", "SHA", "上海虹桥");
redisTemplate.opsForHash().put("myHash", "PVG", "浦东");
Map<Object, Object> hashCache = redisTemplate.opsForHash().entries("myHash");
for (Map.Entry<Object, Object> entry : hashCache.entrySet()) {
System.out.println(entry.getKey() + " - " + entry.getValue());
}
System.out.println("---------------");
User user = new User();
user.setId(3);
user.setAddress("11111");
user.setEmail("zsdfsd111111fsdf@163.com");
user.setName("发11发11发");
user.setSex(1);
System.out.println("==== putting objects into redis ====");
redisTemplate.opsForValue().set( user.getId()+"", user);
System.out.println("==== getting objects from redis ====");
System.out.println( redisTemplate.opsForValue().get(""+user.getId()));
至此,一个完整而简单的整合完毕,可以取出redis里面的缓存。
