我有一個基本的 SpringBoot 2.0.5.RELEASE 應用程序。使用 Spring Initializer、JPA、嵌入式 Tomcat、Thymeleaf 模板引擎，并打包為可執行 JAR我創建了這個 Rest 方法： @GetMapping(path = "/users/notifications", consumes = "application/json", produces = "application/json") public ResponseEntity<List<UserNotification>> userNotifications( @RequestHeader(value = "Authorization") String authHeader) { User user = authUserOnPath("/users/notifications", authHeader); List<UserNotification> menuAlertNotifications = menuService .getLast365DaysNotificationsByUser(user); return ResponseEntity.ok(menuAlertNotifications) .cacheControl(CacheControl.maxAge(60, TimeUnit.SECONDS));; }我想添加一個緩存控制標頭，但我不知道如何...我收到一個編譯錯誤：Multiple markers at this line - The method cacheControl(CacheControl) is undefined for the type ResponseEntity<List<UserNotification>> - CacheControl - cacheControl我還添加了這個屬性 application.propertiessecurity.headers.cache=false

當您使用ResponseEntity.ok(T body)返回類型時，ResponseEntity<T>因為它是一種將數據添加到ResponseEntity.
您需要通過ResponseEntity.ok()沒有返回Builder對象的參數創建的構建器對象。然后，您可以通過 body 方法自己添加數據。
所以你的代碼應該是這樣的
@GetMapping(path = "/users/notifications", consumes = "application/json", produces = "application/json")
public ResponseEntity<List<UserNotification>> userNotifications(
@RequestHeader(value = "Authorization") String authHeader) {
User user = authUserOnPath("/users/notifications", authHeader);
List<UserNotification> menuAlertNotifications = menuService
.getLast365DaysNotificationsByUser(user);
return ResponseEntity.ok().cacheControl(CacheControl.maxAge(60, TimeUnit.SECONDS)).body(menuAlertNotifications);
}
