Question

我使用Spring和iReport以excel格式生成jasper报告。一切正常，但我遇到一个问题，我在iReport中的报告的背景颜色是灰色的，但我在生成的Excel文件中得到了紫色色调。

我将Create Custom Palette设置为true，但它没有任何效果。

我的Jrxml：

Answer 1

在报告jrxml中将属性net.sf.jasperreports.export.xls.white.page.background设置为true。即。

<property name="net.sf.jasperreports.export.xls.white.page.background" value="false" />

Answer 2

绘制彩色文本行为异常的原因

JRXlsExporter 在使用颜色方面有一些限制。

net.sf.jasperreports.engine.export.JRXlsExporter 的源代码片段（在此示例中，我获取了 JR 6.3.0 版本的源代码）< / p>

public void exportText(JRPrintText textElement, JRExporterGridCell gridCell, int colIndex, int rowIndex) throws JRException {
    JRStyledText styledText = getStyledText(textElement);

    if (styledText == null) {
        return;
    }

    short forecolor = getWorkbookColor(textElement.getForecolor()).getIndex();

    TextAlignHolder textAlignHolder = getTextAlignHolder(textElement);
    short horizontalAlignment = getHorizontalAlignment(textAlignHolder);
    short verticalAlignment = getVerticalAlignment(textAlignHolder);
    short rotation = getRotation(textAlignHolder);

    short mode = backgroundMode;
    short backcolor = whiteIndex;
    if (!Boolean.TRUE.equals(sheetInfo.ignoreCellBackground) && gridCell.getCellBackcolor() != null) {
        mode = HSSFCellStyle.SOLID_FOREGROUND;
        backcolor = getWorkbookColor(gridCell.getCellBackcolor()).getIndex();
    }

使用“错误”颜色的原因是来自同一类的 getWorkbookColor（Color）方法：

protected HSSFColor getWorkbookColor(Color awtColor) {
    byte red = (byte)awtColor.getRed();
    byte green = (byte)awtColor.getGreen();
    byte blue = (byte)awtColor.getBlue();
    HSSFColor color = null;

    if (getCurrentConfiguration().isCreateCustomPalette()) {
        try {
            color = palette.findColor(red,green, blue) != null
                ? palette.findColor(red,green, blue)
                : palette.addColor(red,green, blue);
        } catch(Exception e) {
            if(customColorIndex < MAX_COLOR_INDEX) {
                palette.setColorAtIndex(customColorIndex, red, green, blue);
                color = palette.getColor(customColorIndex++);
            } else {
                color = palette.findSimilarColor(red, green, blue);
            }
        }
    }

    return color == null ? getNearestColor(awtColor) : color;
}

通过 getNearestColor（Color）方法定义颜色：

protected HSSFColor getNearestColor(Color awtColor) {
    HSSFColor color = hssfColorsCache.get(awtColor);        
    if (color == null) {
        int minDiff = Integer.MAX_VALUE;
        for (Map.Entry<HSSFColor, short[]> hssfColorEntry : hssfColorsRgbs.entrySet()) {
            HSSFColor crtColor = hssfColorEntry.getKey();
            short[] rgb = hssfColorEntry.getValue();

            int diff = Math.abs(rgb[0] - awtColor.getRed()) + Math.abs(rgb[1] - awtColor.getGreen()) + Math.abs(rgb[2] - awtColor.getBlue());

            if (diff < minDiff) {
                minDiff = diff;
                color = crtColor;
            }
        }

        hssfColorsCache.put(awtColor, color);
    }
    return color;
}

如果 Apache POI 库的 org.apache.poi.hssf.util.HSSFColor 类的受支持颜色列表中没有元素的颜色（背景色），则“最接近”的颜色。

对于灰色（例如，＃F2F2F2），最接近的颜色可以是白色。在这种情况下， JRXlsExporter 将使用白色背景色绘制文本，而忽略 textField 元素的原始背景色。

JRXlsxExporter 没有此问题。

如何解决问题？

我们可以看到 getWorkbookColor 方法对此进行了检查：

if (getCurrentConfiguration().isCreateCustomPalette()) {

如果我们可以打开自定义调色板怎么办？是的，这将解决我们的问题-在这种情况下，将应用原始颜色。

我们可以借助net.sf.jasperreports.export.xls.create.custom.palette属性或Java API来启用自定义托盘。 SimpleXlsExporterConfiguration.setCreateCustomPalette(Boolean)方法的作用与 net.sf.jasperreports.export.xls.create.custom.palette 属性相同。

工作示例

我从 HSSFColor 类中获取了Excel中标准调色板的颜色，并准备了 jrxml 演示了 JRXlsExporter 支持哪些颜色。 / p>

在 JSS （Jaspersoft Studio）中，输出结果如下所示：

如果不应用<property name="net.sf.jasperreports.export.xls.create.custom.palette" value="true"/>，则生成的 xls 文件将如下所示：

带有“ JRXlsExporter支持的所有颜色”文本的 textField 文本具有backcolor="#F2F2F2"属性（这是灰色），但是生成的文本没有背景色（颜色是白色）。

使用自定义调色板，生成的结果是：

我们可以看到，应用自定义调色板解决了 JRXlsExporter 的问题。
