一、引言
记录工作中springboot使用的redis配置,后面少采坑,本篇使用的是RedisTemplate来实现springboot和redis的单机版、集群版和哨兵模式。
二、步骤
1、maven依赖
org.springframework.boot
spring-boot-starter-data-redis
2、创建一个redis.properties的配置文件
#Matser的ip地址
redis.hostName=192.168.177.128
#端口号
redis.port=6382
#如果有密码
redis.password=
#客户端超时时间单位是毫秒 默认是2000
redis.timeout=10000
#最大空闲数
redis.maxIdle=300
#连接池的最大数据库连接数。设为0表示无限制,如果是jedis 2.4以后用redis.maxTotal
#redis.maxActive=600
#控制一个pool可分配多少个jedis实例,用来替换上面的redis.maxActive,如果是jedis 2.4以后用该属性
redis.maxTotal=1000
#最大建立连接等待时间。如果超过此时间将接到异常。设为-1表示无限制。
redis.maxWaitMillis=1000
#连接的最小空闲时间 默认1800000毫秒(30分钟)
redis.minEvictableIdleTimeMillis=300000
#每次释放连接的最大数目,默认3
redis.numTestsPerEvictionRun=1024
#逐出扫描的时间间隔(毫秒) 如果为负数,则不运行逐出线程, 默认-1
redis.timeBetweenEvictionRunsMillis=30000
#是否在从池中取出连接前进行检验,如果检验失败,则从池中去除连接并尝试取出另一个
redis.testOnBorrow=true
#在空闲时检查有效性, 默认false
redis.testWhileIdle=true
#redis集群配置
spring.redis.cluster.nodes=192.168.177.128:7001,192.168.177.128:7002,192.168.177.128:7003,192.168.177.128:7004,192.168.177.128:7005,192.168.177.128:7006
spring.redis.cluster.max-redirects=3
#哨兵模式
#redis.sentinel.host1=192.168.177.128
#redis.sentinel.port1=26379
#redis.sentinel.host2=172.20.1.231
#redis.sentinel.port2=26379
3、封装redis工具类
public class RedisUtil {
private RedisTemplate redisTemplate;
public void setRedisTemplate(RedisTemplate redisTemplate) {
this.redisTemplate = redisTemplate;
}
//=============================common============================
/**

*/
public Boolean expire(String key, long timeout) {
try {

redisTemplate.expire(key, timeout, TimeUnit.SECONDS);
}
return true;
} catch (Exception e) {
return false;
}
}
/**
* 获取缓存有效时间
*
* @param key 键 不能为null
* @return 时间(秒) 返回0代表为永久有效
*/
public long getExpire(String key) {
return redisTemplate.getExpire(key, TimeUnit.SECONDS);
}
/**
* 判断key是否存在
*
* @param key
* @return true 存在 false不存在
*/
public boolean hasKey(String key) {
return redisTemplate.hasKey(key);
}
public void delete(String... key) {
if (key != null && key.length >= 1) {
if (key.length == 1) {
redisTemplate.delete(key[1]);
} else {
redisTemplate.delete(CollectionUtils.arrayToList(key));
}
}
}
//============================String=============================
/**

*
* @param key
* @return
*/
public Object get(String key) {
return key == null ? null : redisTemplate.opsForValue().get(key);
}
/**
* 普通缓存存入
*
* @param key
* @param value
* @return
*/
public boolean set(String key, Object value) {
try {
redisTemplate.opsForValue().set(key, value);
return true;
} catch (Exception e) {
return false;
}
}
/**
* 普通缓存放入设置缓存时间
*
* @param key
* @param value
* @param time
* @return
*/
public boolean set(String key, String value, long time) {
try {
if (time > 0) {
redisTemplate.opsForValue().set(key, value, time, TimeUnit.SECONDS);
} else {
set(key, value);
}
return true;
} catch (Exception e) {
return false;
}
}
/**
* 递增
*
* @param key
* @param increData
* @return
*/
public long increment(String key, long increData) {
if (increData < 0) {
throw new RuntimeException("数值必须大于0");
}
return redisTemplate.opsForValue().increment(key, increData);
}
/**
* 递减
*
* @param key
* @param increData
* @return
*/
public long decr(String key, long increData) {
if (increData < 0) {
throw new RuntimeException("数值必须大于0");
}
return redisTemplate.opsForValue().increment(key, -increData);
}
//================================Map=================================
/**
* hashset
*
* @param key
* @param map
*/
public boolean hmset(String key, Map map) {
try {
redisTemplate.opsForHash().putAll(key, map);
return true;
} catch (Exception e) {
return false;
}
}
/**
* hashset 放入并设置有效期
*
* @param key
* @param map
* @param time
* @return
*/
public boolean hmset(String key, Map map, long time) {
try {
redisTemplate.opsForHash().putAll(key, map);
if (time > 0) {
expire(key, time);
}
return true;
} catch (Exception e) {
return false;
}
}
/**
* 获取hashKey对应的所有键值
* @param key
* @return
*/
public Map

redisTemplate.setHashKeySerializer(new StringRedisSerializer());
redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
//开启事务
redisTemplate.setEnableTransactionSupport(true);
return redisTemplate;
}
@Bean
public JedisPoolConfig jedisPoolConfig(){
