发布时间：2020-12-15 05:03:10 所属栏目：Java 来源：网络整理
导读：我有这样的 Spring MVC控制器： @Controller@RequestMapping(value = "/user")public class UserController { ..... @Cacheable(value = "users",key = "#id") @RequestMapping(value = "/get",method = RequestMethod.GET) @ResponseBody public User getUs
|
我有这样的
Spring MVC控制器：
@Controller
@RequestMapping(value = "/user")
public class UserController {
.....
@Cacheable(value = "users",key = "#id")
@RequestMapping(value = "/get",method = RequestMethod.GET)
@ResponseBody
public User getUser(Long id){
return userService.get(id);
}
....
}
我想将标题Last-Modified添加到GetUser Web服务的HTTP响应中. 解决方法
这个怎么样：
@Controller
@RequestMapping(value = "/user")
class UserController {
@Cacheable(value = "users",key = "#id")
@RequestMapping(value = "/get",method = RequestMethod.GET)
@ResponseBody
public ResponseEntity<User> getUser(Long id) {
HttpHeaders headers = new HttpHeaders();
headers.set("Last-Modified",dateFormat.format(new Date()));
return new ResponseEntity<SecurityProperties.User>(headers,userService.get(id),HttpStatus.OK);
}
}
