在使用itext与flying saucer生成PDF的过程中遇到右侧内容不显示的问题。经过搜索和研究，发现原因为中文字符无法按照英文的空格分组规则正确换行。通过修改`org.xhtmlrenderer.layout.Breaker`类，添加新方法以适应中文字符的换行规则，成功解决了显示不全的故障。

在一次项目中使用 itext + flying saucer 方案生成PDF时 ,出现了右边不显示.

百度Google了大半天,终于找到了解决办法:

老外做的东西是将英文按空格分组，每组判断其位置+长度是否超出边界，超出的话将该组丢到下一行，但是中文里面基本没有空格，所以就无奈了。

修改了org.xhtmlrenderer.layout.Breaker类，添加了2个方法，修改了109行和121行，由原来的按空格分组改为调用getStrRight按新的方式分组来获取字符的右边界值:
