Spring Boot2.0之整合Redis

需要的maven依赖 jar包，是对Jedis的封装

maven依赖：

 #####用代码获取配置文件 灵活获取密码方案

　　

redis中代码的封装：

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;

    //这样该方法支持多种数据类型

    public void set(String key , Object object, Long time){

        if (object instanceof String ) {  //判断下是String类型不

            String argString =(String)object;  //强转下

            //存放String类型的

            stringRedisTemplate.opsForValue().set(key, argString);

        }

        //如果存放Set类型

        if (object instanceof Set) {

            Set<String> valueSet =(Set<String>)object;

            for(String string:valueSet){

                stringRedisTemplate.opsForSet().add(key, string);  //此处点击下源码看下 第二个参数可以放好多

            }

        }

        //设置有效期

        if (time != null) {

            stringRedisTemplate.expire(key, time, TimeUnit.SECONDS);

        }

    }

    //做个封装

    public void setString(String key, Object object){

        String argString =(String)object;  //强转下

        //存放String类型的

        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);  //此处点击下源码看下 第二个参数可以放好多

        }

    }

    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); //超时时间500s   l表示long型

       return "成功";

   }

   @RequestMapping("get")

   public String get(String key){

       return redisService.getString(key);

   }

}

启动类

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);

}

}

运行结果：

redis：

到期了后 就没了哦 过期了
