我在SpringBoot应用程序中为每个不正确的REST URL抛出CustomException。 但是，在将Spring Boot 1.5.4升级到2.0.4版本后，DefaultErrorAttributes无法执行。
我以前使用的是
import org.springframework.boot.autoconfigure.web.DefaultErrorAttributes;
但是Spring boot 2已将上述类更改为：
import org.springframework.boot.web.servlet.error.DefaultErrorAttributes;
但是升级后，它会返回BLANK JSON请求。尽管在调试时，我确定我们会抛出CDBaseException。
下面是我定义为Component的DefaultErrorAttributes的实现。

下面是我的CustomException实现：
public class CDBaseException extends RuntimeException {
public CDBaseException(int code,String message,Exception ex) {
super(message,ex);
this.message=message;
this.code=code;
}
}
这是我引发此异常的方式：
private static void isUriInvalid(boolean isValidUri) {
if (!isValidUri) {
throw new CDBaseException(HttpStatus.BAD_REQUEST.value(), CDConstants.URL_NOT_FOUND_MSG);
}
}
我唯一关心的是，在升级SpringBoot之前，它运行良好。但现在不工作。我做错什么了吗？
