ThrowablerootCause)
Constructs a new servlet exception when the servlet needs to throw an exception and include a message about the "root cause" exception that interfered with its normal operation, including a description message. 构建一个新的servlet异常，servlet需要时抛出，包含妨碍正常操作（包括描述信息）的根异常信息。
Parameters:
message - a String containing the text of the exception message 包含异常信息文本的String
rootCause - the Throwable exception that interfered with the servlet's normal operation, making this servlet exception necessary 妨碍servlet正常操作的Throwable异常，必要时构建servlet异常
<!-- -->
ServletException
public ServletException(ThrowablerootCause)
Constructs a new servlet exception when the servlet needs to throw an exception and include a message about the "root cause" exception that interfered with its normal operation. The exception's message is based on the localized message of the underlying exception. 构建一个新的servlet异常，servlet需要时抛出，包含妨碍正常操作的根异常信息。该异常信息基于底层异常的本地化信息。
This method calls the getLocalizedMessage method on the Throwable exception to get a localized exception message. When subclassing ServletException, this method can be overridden to create an exception message designed for a specific locale. 该方法调用Throwable异常的getLocalizedMessage方法来获取本地化异常信息。 当子类化ServletException时，可以重写该方法来创建专为本地化设计的异常信息。
Parameters:
rootCause - the Throwable exception that interfered with the servlet's normal operation, making the servlet exception necessary 妨碍servlet正常操作的Throwable异常，必要时构建servlet异常
