二：springboot整合redis

1. maven依赖导入

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-data-redis</artifactId>
       <version>2.1.15.RELEASE</version>
   </dependency>
   

2. yml配置

   spring
   	redis:
   	    host: 127.0.0.1
   	    port: 6379
   	    password: 123456
   	    # Redis数据库索引（默认为0）
   	    database: 0
   	    # 连接超时时间(毫秒)，0为禁用
   	    timeout: 1000
   

3. 自定义redisTemplate替换spring boot的redisTemplate

   package com.lmy.config;
   
   import com.fasterxml.jackson.annotation.JsonAutoDetect;
   import com.fasterxml.jackson.annotation.PropertyAccessor;
   import com.fasterxml.jackson.databind.ObjectMapper;
   import org.springframework.context.annotation.Bean;
   import org.springframework.data.redis.connection.RedisConnectionFactory;
   import org.springframework.data.redis.core.RedisTemplate;
   import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
   import org.springframework.data.redis.serializer.StringRedisSerializer;
   import org.springframework.stereotype.Component;
   
   /**

    * @description : 自定义redisTemplate,解决序列化及强转RedisTemplate => RedisTemplate问题
    */
   @Component
   public class RedisConfig {
       @Bean
       public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
           // 泛型改成 String Object，方便我们的使用
           RedisTemplate<String, Object> template = new RedisTemplate<>();
           // Json序列化配置
           // 使用 json解析对象
           Jackson2JsonRedisSerializer objectJackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
           ObjectMapper om = new ObjectMapper();
           // 通过 ObjectMapper进行转义
           om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
           om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
           objectJackson2JsonRedisSerializer.setObjectMapper(om);
           // String的序列化
           StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
           // key和 hashKey采用 string序列化
           template.setKeySerializer(stringRedisSerializer);
           template.setHashKeySerializer(stringRedisSerializer);
           // value和 hashValue采用 JSON序列化
           template.setValueSerializer(objectJackson2JsonRedisSerializer);
           template.setHashValueSerializer(objectJackson2JsonRedisSerializer);
   
           template.setConnectionFactory(redisConnectionFactory);
           template.afterPropertiesSet();
           return template;
       }
   }
   

4. 单元测试

   package com.lmy.redis;
   
   import com.lmy.UtilsDemoApplication;
   import com.lmy.dto.rsp.User;
   import com.lmy.service.TestService;
   import org.junit.Test;
   import org.junit.runner.RunWith;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.boot.test.context.SpringBootTest;
   import org.springframework.data.redis.core.RedisTemplate;
   import org.springframework.test.context.ActiveProfiles;
   import org.springframework.test.context.junit4.SpringRunner;
   
   /**
    * @author : liu ming yong
    * @date : 2023/2/28 下午 2:34
    * @description : redis测试
    */
   @RunWith(SpringRunner.class)
   @SpringBootTest(classes = UtilsDemoApplication.class)
   @ActiveProfiles(value = {"dev"})
   public class RedisTest {
   
       @Autowired
       private RedisTemplate redisTemplate;
   
       @Test
       public void testRedis() {
   //        Jedis jedis = new Jedis("101.35.117.72", 6379);
   //        jedis.auth("lmy19960215");
   //        jedis.set("userName","风范");
   //        jedis.set("sex","女");
   //        jedis.set("age","1");
   //        System.out.println(jedis.get("userName")+"是个"+jedis.get("age")+"岁的"+jedis.get("sex")+"童鞋");
   
   //        Boolean userName = redisTemplate.delete("userName");
   //        Boolean age = redisTemplate.delete("age");
   //        Boolean sex = redisTemplate.delete("sex");
   //
   //        redisTemplate.opsForValue().set("userName","啊hi");
   //        redisTemplate.opsForValue().set("age","2");
   //        redisTemplate.opsForValue().set("sex","女");
   
           User user = new User();
           user.setUserName("回啊");
           user.setAge("3");
           user.setSex("女");
   
   //        redisTemplate.opsForValue().set("user",user);
           System.out.println(redisTemplate.opsForValue().get("user"));
   
          Object o =  redisTemplate.opsForValue().get("user");
          if (o!=null) {
              User myUser = (User)o;
              System.out.println(myUser.getUserName()+"是个"+myUser.getAge()+"岁的"+myUser.getSex()+"童鞋");
          }
   
       }
   }
