redis项目上使用

1. pom文件

       <!-- redis -->
       <dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-data-redis</artifactId>
         <exclusions>
           <exclusion>
             <groupId>io.lettuce</groupId><artifactId>lettuce-core</artifactId>
           </exclusion>
         </exclusions>
       </dependency>
       <dependency>
         <groupId>redis.clients</groupId>
         <artifactId>jedis</artifactId>
         <version>3.6.1</version>
       </dependency>

    

2. 配置文件

   spring:
     redis:
       host: localhost
       port: 6379

    

3. 代码

   @Configuration
   public class RedisConfig {
       @Bean
       public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
           RedisTemplate<String, Object> template = new RedisTemplate<>();
   
           //设置Redis链接工厂对象
           template.setConnectionFactory(connectionFactory);
   
           // 设置String键z值的序列化方式为 String
           template.setKeySerializer(new StringRedisSerializer());
           //设置value序列化
           template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
   
           // 设置Hash Key键值的序列化方式为 JSON
           template.setHashKeySerializer(new GenericJackson2JsonRedisSerializer());
           template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
   
           return template;
       }
   }

    

4. 使用和获取

       @Autowired
       private RedisTemplate<String, Object> redisTemplate;
   
       @GetMapping("/useRedis")
       public String useRedis(){
           redisTemplate.opsForValue().set("USER_KEY_PREFIX",115);
           return "";
       }
   
       @GetMapping("/getRedis")
       public String getUserById() {
           Object user = redisTemplate.opsForValue().get("USER_KEY_PREFIX");
           return user.toString();
       }
