方法详细资料

• setSupportDtd

  public void setSupportDtd​(boolean supportDtd)

  Indicate whether DTD parsing should be supported.

  Default is false meaning that DTD is disabled.

• isSupportDtd

  public boolean isSupportDtd()

  Return whether DTD parsing is supported.

• setProcessExternalEntities

  public void setProcessExternalEntities​(boolean processExternalEntities)

  Indicate whether external XML entities are processed when unmarshalling.

  Default is false, meaning that external entities are not resolved. Note that processing of external entities will only be enabled/disabled when the Source passed to unmarshal(Source) is a SAXSource or StreamSource. It has no effect for DOMSource or StAXSource instances.

  Note: setting this option to true also automatically sets setSupportDtd(boolean) to true.

• isProcessExternalEntities

  public boolean isProcessExternalEntities()

  Return whether XML external entities are allowed.
