本文主要是介绍Jasperreports+jaspersoft studio 实现支持富文本格式的数据,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
昨天有位博友给我发邮件问我:Jasperreports+jaspersoft studio 如何实现支持富文本格式的数据!
其实,我也是第一次遇到这个问题;我就百度搜索,我记得之前:我解决过用百度编辑器,解析富文本格式的数据,是设置一个属性;
最后,只百度到一篇文章;https://zhidao.baidu.com/question/1430121390482093659.html
废话不多说了!看下图:
这是普通的数据展示,没问题的
修改数据表里面的数据如下:
页面显示如下:
图中的样式:不是我想要的,我想让<u></u> 变成下划线
解决方法如下:
最后成功解决:
代码如下:
