springboot+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

 1 ##########redis############
 2 
 3 #redis的IP地址
 4 spring.redis.host=localhost  
 5 #redis的端口
 6 spring.redis.port=6379
 7 #redis的密码
 8 spring.redis.password=123456
 9 #redis默认有16个数据库，使用DB0
10 spring.redis.database=0

创建RedisComponent类

 1 package com.woniu.RedisComponent;
 2 
 3 import org.apache.hadoop.mapred.gethistory_jsp;
 4 import org.springframework.beans.factory.annotation.Autowired;
 5 import org.springframework.data.redis.core.StringRedisTemplate;
 6 import org.springframework.data.redis.core.ValueOperations;
 7 import org.springframework.stereotype.Component;
 8 
 9 
10 @Component
11 public class RedisComponent {
12     @Autowired
13     private StringRedisTemplate stringRedisTemplate;
14     
15     public void set(String key, String value){
16         ValueOperations<String, String> ops = this.stringRedisTemplate.opsForValue();
17         boolean bExistent = this.stringRedisTemplate.hasKey(key);
18         if (bExistent) {
19             System.out.println("this key is bExistent!");
20         }else{
21             ops.set(key, value);
22         }
23     }
24     
25     public String get(String key){
26         return this.stringRedisTemplate.opsForValue().get(key);
27     }
28     
29     public void del(String key){
30         this.stringRedisTemplate.delete(key);
31     }
32 }

创建WebController类

 1 package com.woniu.controller;
 2 
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.web.bind.annotation.PathVariable;
 5 import org.springframework.web.bind.annotation.RequestMapping;
 6 import org.springframework.web.bind.annotation.RestController;
 7 
 8 import com.woniu.RedisComponent.RedisComponent;
 9 
10 @RestController
11 @RequestMapping(value="/web")
12 public class WebController {
13     
14     @Autowired
15     private RedisComponent redisComponet;
16     
17     @RequestMapping(value="/set/{key}/{value}")
18     public String set(@PathVariable String key, @PathVariable String value){
19         redisComponet.set(key, value);
20         return "set key succ!";
21     }
22     
23     @RequestMapping(value="/get/{key}")
24     public String get(@PathVariable String key){
25         return redisComponet.get(key);
26     }
27     
28     @RequestMapping(value="/del/{key}")
29     public void del(@PathVariable String key){
30         redisComponet.del(key);
31     }
32 }

本机安装redis，设置密码为123456，启动redis。
