引入依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId></dependency>

redisTemplate_41">注册redisTemplate

package org.example.springbootredis.config;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.StringRedisSerializer;@Configuration
public class RedisConfig {@Beanpublic RedisTemplate<String, String> redisTemplate(RedisConnectionFactory connectionFactory) {RedisTemplate<String, String> redisTemplate = new RedisTemplate<>();StringRedisSerializer serializer = new StringRedisSerializer();redisTemplate.setKeySerializer(serializer);redisTemplate.setValueSerializer(serializer        );redisTemplate.setConnectionFactory(connectionFactory);return redisTemplate;}
}

编写工具类

package org.example.springbootredis.redisutil;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;@Component
public class RedisUtil {@Autowiredprivate RedisTemplate<String, String> redisTemplate;public Object get(String key) {return key == null ? null : redisTemplate.opsForValue().get(key);}public void set(String key, String value) {redisTemplate.opsForValue().set(key, value);}public void del(String key) {redisTemplate.delete(key);}
}

编写 Controller测试

package org.example.springbootredis.controller;import org.example.springbootredis.redisutil.RedisUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;@RestController
public class RedisController {@Autowiredprivate RedisUtil redisUtil;@PostMapping("/setKey")public void setKey(@RequestParam(value = "key") String key, @RequestParam(value = "value") String value) {System.out.println("setKey key: " + key + ", value: " + value);redisUtil.set(key, value);}@PostMapping("/getKey")public String getKey(@RequestParam(value = "key") String key) {System.out.println("getKey key: " + key);Object value = redisUtil.get(key);return (String) value;}@PostMapping("/delKey")public void delKey(@RequestParam(value = "key") String key) {System.out.println("delKey key: " + key);redisUtil.del(key);}
}
