ssm 集成 redis 做缓存
1.配置 文件redis.properties
#redis pool config
redis.pool.maxActive=200
redis.pool.maxIdle=100
redis.pool.maxWaitMillis=100
redis.pool.testOnBorrow=true
#redis config
redis.host=127.0.0.1 //连接地址
redis.port=6379 //默认端口
redis.timeout=2000
redis.password= //我这里没有密码
redis.database=0 //第几个库
redis.dbindex=8
redis.usePool=1
redis.default.expire=1800000
2.spring-redis.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"

<!-- redis 配置数据 -->
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxIdle" value="${redis.pool.maxIdle}"></property>
<property name="maxTotal" value="${redis.pool.maxActive}" />
<property name="maxWaitMillis" value="${redis.pool.maxWaitMillis}" />
<property name="testOnBorrow" value="${redis.pool.testOnBorrow}" />
</bean>
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" destroy-method="destroy">
<property name="poolConfig" ref="jedisPoolConfig"/>
<property name="hostName" value="${redis.host}"/>
<property name="port" value="${redis.port}"/>
<property name="database" value="${redis.database}"/>
<!-- <property name="password" value="${redis.password}"></property> -->
<property name="timeout" value="${redis.timeout}"></property>
</bean>
<!-- 配置redisTemplate 模版 -->
<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory" />
<property name="keySerializer">
<bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
</property>
<property name="valueSerializer">
<bean
class="org.springframework.data.redis.serializer.StringRedisSerializer">
</bean>
</property>
</bean>
</beans>
3.redis service 我这里没有采用注解形式的
package com.cn.ag.redis;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.dao.DataAccessException;
import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.core.RedisCallback;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;
public class RedisService {
@Autowired
private RedisTemplate<String, String> redisTemplate;
private static final Logger log=Logger.getLogger(RedisService.class);
/**
*
* @Title: put
* @Description: 插入
* @param @param keyId
* @param @param entity
* @param @return 设定文件
* @return boolean 返回类型
* @date 2018年12月27日 下午2:09:37
* @throws
*/
public boolean put(String keyId, String entity) {
boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
RedisSerializer<String> serializer = redisTemplate.getStringSerializer();
byte[] key = serializer.serialize(keyId);
byte[] value = serializer.serialize(entity);
return connection.setNX(key, value);
}
});
log.info("【插入数据成功】");
return result;
}
/**
*
* @Title: remove
* @Description: 删除
* @param @param key 设定文件
* @return void 返回类型
* @date 2018年12月27日 下午2:10:53
* @throws
*/
public void remove(String key) {
redisTemplate.delete(key);
log.info("【删除数据成功】");
}
/**
*
* @Title: get
* @Description: 查询
* @param @param keyId
* @param @return 设定文件
* @return String 返回类型
* @date 2018年12月27日 下午2:10:31
* @throws
*/
public String get(final String keyId) {
String entity = redisTemplate.execute(new RedisCallback<String>() {
public String doInRedis(RedisConnection connection) throws DataAccessException {
RedisSerializer<String> serializer = redisTemplate.getStringSerializer();
byte[] key = serializer.serialize(keyId);
byte[] value = connection.get(key);
if (value == null) {
return null;
}
return serializer.deserialize(value);
}
});
log.info("【查询数据成功】");
return entity;
}
}
4.Controller 调用
package com.cn.ag.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.cn.ag.redis.RedisService;
@Controller
@RequestMapping("/test")
public class Test {
@Autowired
private RedisService redisService;
@RequestMapping(value = "/test", produces = "application/json")
@ResponseBody
public String create() {
//简单查询
return redisService.get("k1");
}
}
