Spring Boot2.0之整合Redis

須要的maven依賴 jar包，是對Jedis的封裝

maven依賴：

 項目的目錄結構：

yml:

spring:
  redis:
    database: 0    
#    host:  192.168.91.3
#   port:  6379
#    password:  123
    jedis:
      pool:
        max-active: 8
        max-wait: -1
        max-idle: 8
        min-idle: 0
    timeout: 10000
    cluster:
      nodes:
        - 192.168.91.5:9001
        - 192.168.91.5:9002
        - 192.168.91.5:9003
        - 192.168.91.5:9004

 #####用代碼獲取配置文件 靈活獲取密碼方案

　　

redis中代碼的封裝：

package com.toov5.service; import java.util.Set; import java.util.concurrent.TimeUnit; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.StringRedisTemplate; import org.springframework.stereotype.Component; @Component public class RedisService { @Autowired private StringRedisTemplate stringRedisTemplate; //這樣該方法支持多種數據類型 
    public void set(String key , Object object, Long time){ if (object instanceof String ) {  //判斷下是String類型不
            String argString =(String)object;  //強轉下 //存放String類型的
 stringRedisTemplate.opsForValue().set(key, argString); } //若是存放Set類型
        if (object instanceof Set) { Set<String> valueSet =(Set<String>)object; for(String string:valueSet){ stringRedisTemplate.opsForSet().add(key, string); //此處點擊下源碼看下 第二個參數能夠放好多
 } } //設置有效期
        if (time != null) { stringRedisTemplate.expire(key, time, TimeUnit.SECONDS); } } //作個封裝
    public void setString(String key, Object object){ String argString =(String)object;  //強轉下 //存放String類型的
 stringRedisTemplate.opsForValue().set(key, argString); } public void setSet(String key, Object object){ Set<String> valueSet =(Set<String>)object; for(String string:valueSet){ stringRedisTemplate.opsForSet().add(key, string); //此處點擊下源碼看下 第二個參數能夠放好多
 } } public String getString(String key){ return stringRedisTemplate.opsForValue().get(key); } }

controller

package com.toov5.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import com.toov5.service.RedisService; @RestController public class IndexController { @Autowired private RedisService redisService; @RequestMapping("/setString") public String setString(String key, String value){ redisService.set(key, value, 500l); //超時時間500s l表示long型
       return "成功"; } @RequestMapping("get") public String get(String key){ return redisService.getString(key); } }

啓動類

package com.toov5.app; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication(scanBasePackages={"com.toov5.*"}) public class app { public static void main(String[] args) { SpringApplication.run(app.class, args); } }

運行結果：

到期了後 就沒了哦 過時了
