本篇基於Springboot2.0 + Redis實現數據緩存及分庫存儲,上一篇主要使用官方推薦的RedisTemplate實現,這篇我主要以Jedis的方式來實現Redis的操做。這裏再重複一遍,兩種方式均可以實現對Redis的操做,RedisTemplate是對Jedis作了封裝,官方推薦使用Redistemplate方式。web
本文使用idea工具構建Springboot+SpringMvc+Thymeleaf+SpringDataJPA+MySql+Redis項目redis
GitHub地址:https://github.com/jwwam/springbootRedis2.gitspring
仍是來樣子先看下項目demo的目錄結構,基本的目錄結構和上篇沒什麼差異。文末會給出pom包配置。
1.建立redis.properties配置文件
#redis配置開始 # Redis數據庫索引(默認爲0) spring.redis.database=0 # Redis 服務器地址 spring.redis.host=localhost # Redis服務器鏈接端口 spring.redis.port=6379 # Redis服務器鏈接密碼(默認爲空) spring.redis.password=123456 # 鏈接池最大鏈接數(使用負值表示沒有限制) spring.redis.jedis.pool.max-active=1024 # 鏈接池最大阻塞等待時間(使用負值表示沒有限制) spring.redis.jedis.pool.max-wait=10000 # 鏈接池中的最大空閒鏈接 spring.redis.jedis.pool.max-idle=200 # 鏈接池中的最小空閒鏈接 spring.redis.jedis.pool.min-idle=0 # 鏈接超時時間(毫秒) spring.redis.timeout=10000 #redis配置結束 spring.redis.block-when-exhausted=true
這裏咱們要注意max-active,max-wait,max-idle,min-idle這幾個參數版本不一樣寫法也不同,我這裏因爲引入了最新的Jedis包因此寫法如上,請注意。
2.添加配置類RedisConfig.java
-
package com.springboot.demo.base.config;
-
-
import lombok.extern.slf4j.Slf4j;
-
import org.springframework.beans.factory.annotation.Value;
-
import org.springframework.context.annotation.Bean;
-
import org.springframework.context.annotation.Configuration;
-
import org.springframework.context.annotation.PropertySource;
-
import redis.clients.jedis.JedisPool;
-
import redis.clients.jedis.JedisPoolConfig;
-
-
@Configuration
-
@PropertySource(
"classpath:redis.properties")
-
@Slf4j
-
public
class RedisConfig {
-
-
@Value(
"${spring.redis.host}")
-
private String host;
-
-
@Value(
"${spring.redis.port}")
-
private
int port;
-
-
@Value(
"${spring.redis.timeout}")
-
private
int timeout;
-
-
@Value(
"${spring.redis.jedis.pool.max-idle}")
-
private
int maxIdle;
-
-
@Value(
"${spring.redis.jedis.pool.max-wait}")
-
private
long maxWaitMillis;
-
-
@Value(
"${spring.redis.password}")
-
private String password;
-
-
@Value(
"${spring.redis.block-when-exhausted}")
-
private
boolean blockWhenExhausted;
-
-
@Bean
-
public JedisPool redisPoolFactory() throws Exception{
-
log.info(
"JedisPool注入成功!!");
-
log.info(
"redis地址:" + host +
":" + port);
-
JedisPoolConfig jedisPoolConfig =
new JedisPoolConfig();
-
jedisPoolConfig.setMaxIdle(maxIdle);
-
jedisPoolConfig.setMaxWaitMillis(maxWaitMillis);
-
// 鏈接耗盡時是否阻塞, false報異常,ture阻塞直到超時, 默認true
-
jedisPoolConfig.setBlockWhenExhausted(blockWhenExhausted);
-
// 是否啓用pool的jmx管理功能, 默認true
-
jedisPoolConfig.setJmxEnabled(
true);
-
JedisPool jedisPool =
new JedisPool(jedisPoolConfig, host, port, timeout, password);
-
return jedisPool;
-
}
-
-
}
3.建立RedisUtil.java工具類,注意,這是一個很是完整的Jedis操做redis的工具類,裏面多數方法我都加入了分庫操做,使用時注意規範就好。

4.示例說明,一樣的,我拿出最基本的set方法,indexdb參數爲須要自定義的redis庫編碼,finally中咱們回收此鏈接放入鏈接池。
-
public String set(String key, String value,int indexdb) {
-
Jedis jedis =
null;
-
try {
-
jedis = jedisPool.getResource();
-
jedis.select(indexdb);
-
return jedis.set(key, value);
-
}
catch (Exception e) {
-
-
log.error(e.getMessage());
-
return
"0";
-
}
finally {
-
returnResource(jedisPool, jedis);
-
}
-
}
仍是同樣,這裏新建Controller進行測試操做
RedisController.java
-
package com.springboot.demo.controller;
-
-
import com.springboot.demo.base.controller.BaseController;
-
import com.springboot.demo.base.utils.RedisConstants;
-
import com.springboot.demo.base.utils.RedisUtil;
-
import com.springboot.demo.base.utils.StateParameter;
-
import org.springframework.beans.factory.annotation.Autowired;
-
import org.springframework.stereotype.Controller;
-
import org.springframework.ui.ModelMap;
-
import org.springframework.web.bind.annotation.RequestMapping;
-
import org.springframework.web.bind.annotation.RequestMethod;
-
import org.springframework.web.bind.annotation.ResponseBody;
-
-
/**
-
* @ClassName: RedisController
-
* @Auther: zhangyingqi
-
* @Date: 2018/8/29 16:15
-
* @Description:

*/
-
@Controller
-
@RequestMapping(value=
"/redis")
-
public
class RedisController extends BaseController {
-
@Autowired
-
RedisUtil redisUtil;
-
-
/**
-
* @auther: zhangyingqi
-
* @date: 16:23 2018/8/29
-
* @param: []
-
* @return: org.springframework.ui.ModelMap
-
* @Description: 執行redis寫/讀/生命週期
-
*/
-
@RequestMapping(value =
"getRedis",method = RequestMethod.POST)
-
@ResponseBody
-
public ModelMap getRedis(){
-
redisUtil.set(
"20182018",
"這是一條測試數據", RedisConstants.datebase1);
-
Long resExpire = redisUtil.expire(
"20182018",
60, RedisConstants.datebase1);
//設置key過時時間
-
logger.info(
"resExpire="+resExpire);
-
String res = redisUtil.get(
"20182018", RedisConstants.datebase1);
-
return getModelMap(StateParameter.SUCCESS, res,
"執行成功");
-
}
-
-
}
使用@Autowired注入RedisUtil
使用如下語句存儲緩存值
redisUtil.set("20182018","這是一條測試數據", RedisConstants.datebase1);
使用如下語句設置該值的生命週期即有效期,單位是秒
Long resExpire = redisUtil.expire("20182018", 60, RedisConstants.datebase1);//設置key過時時間
啓動項目請求地址:http://localhost:8080/redis/getRedis,返回成功,打開redis客戶端工具,能夠看到在db1中存入了該數據,而且設置了有效時間爲60秒,截圖時還剩餘54秒。
最後給出pom包

實際上只需引入如下兩個依賴便可,注意因爲springboot的版本不一樣,引入redis的配置寫法略有不一樣。我註釋掉的是舊版本的springboot引入redis方式,請留意。

-
<groupId>org.springframework.boot

花了一些時間對這兩種在springboot中引入Redis的方式進行了一個小結,實際使用中發現二者並沒有太大差別,因此任選一個便可。
