Java play自定义onServerError在exception ()内部抛出异常时不会触发

import play.mvc.Http;
import play.mvc.Result;
import play.mvc.Results;

public class MyController extends Controller {

  public Result exception() {
    try {
      // 在这里抛出异常
      throw new Exception("Something went wrong");
    } catch (Exception e) {
      // 将异常信息添加到请求头中
      Http.RequestHeader requestHeader = request().withAttrs(Attrs.create(Attrs.EXCEPTION, e));
      // 调用onServerError方法处理异常
      return onServerError(requestHeader);
    }
  }

  @Override
  protected Result onServerError(Http.RequestHeader request, Throwable exception) {
    // 检查请求头中是否存在异常信息
    Optional<Throwable> optionalException = request.attrs().getOptional(Attrs.EXCEPTION);
    if (optionalException.isPresent()) {
      Throwable e = optionalException.get();
      // 在这里处理异常
      return Results.internalServerError("An error occurred: " + e.getMessage());
    } else {
      // 如果没有异常信息，则调用父类的方法处理异常
      return super.onServerError(request, exception);
    }
  }
}
