jsp <s:property:>显示出数据库中的html 效果

本文介绍在Struts框架中如何使用<s:property>标签正确显示带有HTML标签的内容,通过设置escape属性来确保文本中的格式如加粗等能够被正常解析并展示。

比如数据库中的一条字段为
<p><span style="text-decoration: none;"><strong>你好</strong></span></p>
jsp中用<s:iterator><s:property value = "content"/>取出后全部显示成文字, 并把那些效果显示出来比如<strong>变成加粗而不是一串符号

<s:property:>有个属性叫escape <s:property value = "post.content" escape="false"/>


后面加个escape="false"
