Spring Rest API控制器的缓存响应 [英] Cache response of spring rest api controller

问题描述

是否有通过方法参数来缓存spring REST API的响应?例如，在下面的代码中，如果该国家/地区已经被检索过一次，则从缓存中返回相同的响应(json序列化数据).

Is there anyway to cache the response of spring REST API by method parameter? For example, in below code, return the same response (the json serialized data) from cache if the country is already retrieved once.

@Controller
public class DataController {

      // Can we cache here by country?
     @RequestMapping(value = "/api/info/{country}", method = RequestMethod.GET)
     public CountryInfo getCountryInfo(@PathVariable("country")String country){
          return service.getCountryInfo(country);
     }
}
