6.3 整合 Redis

---

1、创建新项目编写 application.properties 配置文件

# redis 配置
spring.data.redis.host=192.168.1.4
spring.data.redis.port=6379

• 如果不知道主机号的请执行下面代码找到 192.168 开头的局域网地址

ifconfig

2、创建 RedisTestController 测试类

package com.zhong.redis.controller;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;/*** @ClassName : RedisTestController* @Description :* @Author : zhx* @Date: 2024-06-14 15:13*/
@RestController
public class RedisTestController {@AutowiredStringRedisTemplate redisTemplate;@GetMapping("/count")public String count() {Long count = redisTemplate.opsForValue().increment("count");// TODO 常见数据类型 k:v value可以有很多类型////  string: 普通字符串:  redisTemplate.opsForValue()//  list    列表:       redisTemplate.opsForList()//  set:    集合:       redisTemplate.opsForset()//  zset:   有序集合:    redisTemplate.opsForzset()//  hash:   map结构:    redisTemplate.opsForHash()return "访问了[ " + count + " ]次";}
}

3、运行后浏览器访问 地址 刷新测试

http://localhost:8080/count

4、查看虚拟机的 Docker 中的 Redis 是否响应

• Redis 的常用操作演示

package com.zhong.redis;import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ZSetOperations;@SpringBootTest
class Boot307RedisApplicationTests {// TODO 常见数据类型 k:v value可以有很多类型////  string: 普通字符串:  redisTemplate.opsForValue()//  list    列表:       redisTemplate.opsForList()//  set:    集合:       redisTemplate.opsForset()//  zset:   有序集合:    redisTemplate.opsForzset()//  hash:   map结构:    redisTemplate.opsForHash()@AutowiredStringRedisTemplate redisTemplate;@Testvoid testSting() {redisTemplate.opsForValue().set("name", "张三");String name = redisTemplate.opsForValue().get("name");System.out.println(name);}@Testvoid testList() {String listName = "listtest";redisTemplate.opsForList().leftPush(listName, "1");redisTemplate.opsForList().leftPush(listName, "2");redisTemplate.opsForList().leftPush(listName, "3");String leftPop = redisTemplate.opsForList().leftPop(listName);Assertions.assertEquals("3", leftPop);}@Testvoid testSet() {String setName = "settest";redisTemplate.opsForSet().add(setName, "1");redisTemplate.opsForSet().add(setName, "2");redisTemplate.opsForSet().add(setName, "2");redisTemplate.opsForSet().add(setName, "2");redisTemplate.opsForSet().add(setName, "3");Boolean aBoolean = redisTemplate.opsForSet().isMember(setName, "2");Boolean bBoolean = redisTemplate.opsForSet().isMember(setName, "5");Assertions.assertTrue(aBoolean);Assertions.assertFalse(bBoolean);}@Testvoid testZset() {String setName = "zsettest";redisTemplate.opsForZSet().add(setName, "小钟", 100);redisTemplate.opsForZSet().add(setName, "小王", 99);redisTemplate.opsForZSet().add(setName, "小小", 1);redisTemplate.opsForZSet().add(setName, "小大", 2);ZSetOperations.TypedTuple<String> popMax = redisTemplate.opsForZSet().popMax(setName);String value = popMax.getValue();Double score = popMax.getScore();System.out.println(value + "====>" + score);}@Testvoid testHash() {String setName = "amap";redisTemplate.opsForHash().put(setName,"name","张三");redisTemplate.opsForHash().put(setName,"age","18");Object name = redisTemplate.opsForHash().get(setName, "name");System.out.println(name);}}

• 运行结果

• 利用可视化工具查看 redis 一定要刷新才有值可视化工具可以参考这篇文章 Redis 可视化工具 RedisInsight 的保姆级安装以及使用（最新）_redisinsight安装-CSDN博客
