Spring Boot系列教程九：Spring boot集成Redis

一.创建项目

项目名称为 “springboot_redis”，创建过程中勾选 “Web”，“Redis”，第一次创建Maven需要下载依赖包(耐心等待)

二.实现

properties配置文件中添加配置信息

 ##########redis############

 #redis的IP地址
 spring.redis.host=localhost
 #redis的端口
 spring.redis.port=6379
 #redis的密码
 spring.redis.password=123456
 #redis默认有16个数据库，使用DB0
 spring.redis.database=0

创建RedisComponent类

 package com.woniu.RedisComponent;

 import org.apache.hadoop.mapred.gethistory_jsp;
 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;

 @Component
 public class RedisComponent {
     @Autowired
     private StringRedisTemplate stringRedisTemplate;

     public void set(String key, String value){
         ValueOperations<String, String> ops = this.stringRedisTemplate.opsForValue();
         boolean bExistent = this.stringRedisTemplate.hasKey(key);
         if (bExistent) {
             System.out.println("this key is bExistent!");
         }else{
             ops.set(key, value);
         }
     }

     public String get(String key){
         return this.stringRedisTemplate.opsForValue().get(key);
     }

     public void del(String key){
         this.stringRedisTemplate.delete(key);
     }
 }

创建WebController类

 package com.woniu.controller;

 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.web.bind.annotation.PathVariable;
 import org.springframework.web.bind.annotation.RequestMapping;
 import org.springframework.web.bind.annotation.RestController;

 import com.woniu.RedisComponent.RedisComponent;

 @RestController
 @RequestMapping(value="/web")
 public class WebController {

     @Autowired
     private RedisComponent redisComponet;

     @RequestMapping(value="/set/{key}/{value}")
     public String set(@PathVariable String key, @PathVariable String value){
         redisComponet.set(key, value);
         return "set key succ!";
     }

     @RequestMapping(value="/get/{key}")
     public String get(@PathVariable String key){
         return redisComponet.get(key);
     }

     @RequestMapping(value="/del/{key}")
     public void del(@PathVariable String key){
         redisComponet.del(key);
     }
 }

本机安装redis，设置密码为123456，启动redis。
