public JspTagException(String message,
                       Throwable rootCause)

Constructs a new JspTagException when the JSP Tag needs to throw an exception and include a message about the "root cause" exception that interfered with its normal operation, including a description message.

Parameters:: message - a String containing the text of the exception message; rootCause - the Throwable exception that interfered with the JSP Tag's normal operation, making this JSP Tag exception necessary

当 JSP 标记需要抛出异常并且需要包含有关妨碍 JSP 标记正常操作的“根本原因”异常的消息时，构造一个新 JSP 标记异常。该异常消息以底层异常的本地化消息为基础。
此方法调用 `Throwable` 异常的 `getLocalizedMessage` 方法获取本地化异常消息。在子类化 `JspTagException` 时，可重写此方法以创建设计用于特定语言环境的异常消息。

英文文档：
JspTagException

public JspTagException(Throwable rootCause)

Constructs a new JSP Tag exception when the JSP Tag 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.

This method calls the getLocalizedMessage method on the Throwable exception to get a localized exception message. When subclassing JspTagException, this method can be overridden to create an exception message designed for a specific locale.

Parameters:: rootCause - the Throwable exception that interfered with the JSP Tag's normal operation, making the JSP Tag exception necessary
Since:: JSP 2.0
