iText7报错com.itextpdf.kernel.font.PdfType0Font.getCidFontType2(PdfType0Font.java:720)解决

这是由于iText打印中文特殊字符时报错,我是用了windows自带的宋体解决


//创建基础字体
    PdfFont sysFont = PdfFontFactory.createFont("c://windows//fonts//simsun.ttc,1",PdfEncodings.IDENTITY_H, false);//中文设置,解决特殊字符错误,

java.lang.NullPointerException
