我正在尝试使用Apache POI XSLF库为pptx文件设置背景填充颜色.我的代码看起来像这样:

XSLFSlideMaster defaultMaster = ppt.getSlideMasters().get(0);
XSLFSlideLayout layout = defaultMaster.getLayout(SlideLayout.BLANK);
XSLFBackground background = layout.getBackground();
background.setFillColor(Color.BLACK);

结果

Exception in thread "main" java.lang.IllegalStateException: CTShapeProperties was not found.
at org.apache.poi.xslf.usermodel.XSLFShape.getSpPr(XSLFShape.java:240)
at org.apache.poi.xslf.usermodel.XSLFSimpleShape.setFillColor(XSLFSimpleShape.java:549)

我试过在SlideMaster的背景,布局的背景和幻灯片的背景上调用它,都会导致同样的错误.

所以现在我只是想设置一个简单的类,并且无法弄清楚为什么我会出错.这是我的头文件:

#define Mob

class Mob{
private:
    int lvl;
    float hp;
public:
    Mob(int, float); //Error expected an identifier on the float
};

和它的cpp文件

#include "Mob.h"

Mob::Mob(int level, float health) // Error expected an identifier on the int and float
// and an Error: Expected a ; after the )
{
    hp = health;
    lvl = level;
}
