1、引入相关的jar
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
2、配置redis
spring:
redis:
password:
host: 192.168.1.1
3、新增redis配置类
@EnableCaching
@Configuration
@AllArgsConstructor
@AutoConfigureBefore(RedisAutoConfiguration.class)
public class RedisTemplateConfig {
private final RedisConnectionFactory factory;
@Bean
public RedisTemplate<String, Object> redisTemplate() {
RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
redisTemplate.setHashValueSerializer(new JdkSerializationRedisSerializer());
redisTemplate.setConnectionFactory(factory);
return redisTemplate;
}
}
4、使用CacheManger
注意：保存到cache里的实体，一定要序列化
@Autowired
private CacheManager cacheManager;
@GetMapping("/cache")
public Object getCache() {
Cache cache = cacheManager.getCache("cache");
if (cache != null && cache.get("user") != null) {
return cache.get("user").get();
}
User user = new User(1,"zhangsan",20);
cache.put("user", user);
return user;
}
