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
