Springboot (16): Integrated Redis

First, Introduction

Redis is a cache system that can be stored durably and is a high-performance Key-value database.

Second, use

2.1. Add dependencies

<dependency> <groupId>org.springframework.boot</groupId> <artifactId> Spring-boot-starter-data-redis</artifactid></dependency>

2.2. Application.properties Configuration

######################## #redis开始 ######################## #spring. redis.host=192.168.175.13spring.redis.port= 6379spring.redis.password=123456#spring.redis.database=0#spring.redis.pool.max-active=8# Spring.redis.pool.max-idle=8#spring.redis.pool.max-wait=-1#spring.redis.pool.min-idle=0#spring.redis.timeout=0 ######################## #redis结束 #########################

2.3. Service class

Package com.example.demo.utils;import org.springframework.beans.factory.annotation.autowired;import  org.springframework.data.redis.core.StringRedisTemplate;import  org.springframework.data.redis.core.valueoperations;import org.springframework.stereotype.component;/**  * redis Service  * *  @Author:  I love Big gold  *  @Description:  redis service class  *   @Date:  create in 12:02 2017/7/3 */@Componentpublic  class redisutil  {     @Autowired     private StringRedisTemplate  Stringredistemplate;    public void set (String key, string value)  {        valueoperations<string, string> ops  = this.stringredistemplate.opsforvalue ();        if  (! This.stringRedisTemplate.hasKey (key))  {   &nbsP;        ops.set (Key, value);             system.out.println ("set key success");         } else { //  existing before printing  value  value              system.out.println ("this key = "  +  ops.get (key));        }    }     public string get (String key)  {         return this.stringredistemplate.opsforvalue (). Get (Key);    }     public void del (String key)  {         This.stringRedisTemplate.delete (key);     }}

2.4, test

Package com.example.demo;import com.example.demo.utils.redisutil;import org.junit.test;import  org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import  org.springframework.boot.test.context.springboottest;import  Org.springframework.test.context.junit4.SpringRunner, @RunWith (springrunner.class) @SpringBootTestpublic   class springbootredisapplicationtests {    @Autowired    private  redisutil redisutil;    @Test    public void set ()  {       redisutil.set ("Liuy",  "Hello");   }    @Test    public void get ()  {      system.out.println ( Redisutil.get ("Liuy"));   }    @Test    public void del ()  {      redisutil.del ("Liuy");    }}
