其中解决中文问题java代码如下：（此处：.addFont() 方法中 “simsun.ttc” 后不加 “，” ；与BaseFont.createFont 不同
ITextFontResolver fontResolver = renderer.getFontResolver();
fontResolver.addFont(TEMPLATE + "simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
对应的ftl文件中必须加上 ： body{font-family: SimSun}，并且只有body中能显示中文，body外部分不显示
