RedisConfig.java
注意必须是java1.8以上才可以编译通过
@Configuration
@EnableCaching
public class RedisConfig { @Bean
RedisConnectionFactory redisFactory() {
RedisStandaloneConfiguration config = new RedisStandaloneConfiguration();
return new JedisConnectionFactory(config);
} @Bean
RedisTemplate redisTemplate() {
StringRedisTemplate template = new StringRedisTemplate(redisFactory());
template.setValueSerializer(RedisSerializer.json());
return template;
} @Bean
RedisCacheManager cacheManager() {
RedisCacheConfiguration with = RedisCacheConfiguration
.defaultCacheConfig()
.computePrefixWith(cacheName -> "dz147." + cacheName)
.serializeKeysWith(RedisSerializationContext.SerializationPair.
fromSerializer(RedisSerializer.string()))
.serializeValuesWith(RedisSerializationContext.SerializationPair.
fromSerializer(RedisSerializer.json()));
return RedisCacheManager.builder(redisFactory()).cacheDefaults(with).build();
}
}
使用就非常简单了
Controller部分
@GetMapping(value = "/redis/{id}")
//@GetCache(name="news",value="id")
public @ResponseBody News redisTest(@PathVariable("id")int id) {
return newsService.getNewsById(id);
}
Service部分
我们只需要加上@Cacheable注解即可
@Service
public class NewsServiceImpl {
@Autowired
NewsMapper newsMapper; @Cacheable("news")
public News getNewsById(int id) {
return newsMapper.selectByPrimaryKey(id);
}
}
Test部分
@RunWith(SpringRunner.class)
@ContextConfiguration(classes = RootConfig.class)
public class NewsServiceImplTest {
@Autowired
NewsServiceImpl newsService; @Test
public void getNewsById() {
newsService.getNewsById(2);
}
}
