1.概述
2.配置
在官网下载Redis-x64-xxx.zip压缩包,解压后进入其中的目录,将环境变量设置到此电脑中,在Path中添加刚才的安装目录:
1
| C:\xxx\xxx\Redis-x64-xxx
|
3.启动
在cmd中输入:

如图显示在本机开放的端口号。
这时候另启一个 cmd 窗口,原来的不要关闭,不然就无法访问服务端了。
切换到 redis 目录下运行:
1
| redis-cli.exe -h 127.0.0.1 -p 6379
|
设置键值对:
取出键值对:

4.Spring配置
在配置文件中添加:
1 2 3 4
| redis: host: "localhost" port: 6379 timeout: 5000
|
添加redis模板类:RedisTemplate
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
| import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer; import org.springframework.data.redis.serializer.RedisSerializer;
@Configuration public class RedisConfig { @Bean public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory connectionFactory) { RedisTemplate<String, Object> template = new RedisTemplate<>(); template.setConnectionFactory(connectionFactory); RedisSerializer<Object> serializer = new GenericJackson2JsonRedisSerializer(); template.setDefaultSerializer(serializer); return template; } }
|
添加键值对:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
| package com.kd_13.qq_fake.controller;
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.http.HttpStatus; import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.*;
@RestController @RequestMapping("/redis") public class RedisController {
@Autowired private RedisTemplate<String, String> redisTemplate;
@PostMapping("/postkey") public ResponseEntity<String> postKey(@RequestParam String key, @RequestParam String value) { redisTemplate.opsForValue().set(key, value); return ResponseEntity.ok("Key-value pair saved to Redis"); }
@GetMapping("/getvalue") public ResponseEntity<String> getValue(@RequestParam String key) { String value = redisTemplate.opsForValue().get(key); if (value == null) { return ResponseEntity.status(HttpStatus.NOT_FOUND).body("Key not found"); } return ResponseEntity.ok(value); } }
|
其中核心的为:
1
| redisTemplate.opsForValue().set(key, value);
|
1
| String value = redisTemplate.opsForValue().get(key);
