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：
