Answer 1

看http://jasperreports.sourceforge.net/api/net/sf/jasperreports/engine/export/JRHtmlExporterParameter.html#IS_WHITE_PAGE_BACKGROUND

IS_WHITE_PAGE_BACKGROUND 

public static final JRHtmlExporterParameter IS_WHITE_PAGE_BACKGROUND 

A boolean value specifying whether the report background should be white. If this parameter is not set, the default background will appear, depending on the selected CSS styles. 

PROPERTY_WHITE_PAGE_BACKGROUND 

public static final java.lang.String PROPERTY_WHITE_PAGE_BACKGROUND 

Property whose value is used as default state of the IS_WHITE_PAGE_BACKGROUND export flag. 

This property is set by default (true).
