在 JSF 中显示辅助 bean 的值时不要折叠空格
我发现JSF页面上显示的backing bean值会自动折叠空白。如何使显示的值不折叠空白？
例如，我有一个 MBean，它有一个字符串变量 test 并分配值
"test test", when I render it using
<h1>${MBean.test}</h1> , it just give out test test which all the white-spaces in the middle collapse to a white-space only.如果我使用
更新：我仍然认为它特定于 JSF ，因为当我使用
I found that the backing bean value displayed on the JSF page will collapse the white-space automatically .How can I make the value displayed do not collapse the white-space??
For example , I have a MBean which has a String variable test and assign the value
"test test"
, when I render it using <h1>${MBean.test}</h1> , it just give out test test which all the white-spaces in the middle collapse to a white-space only.
This behavior also happens if I display the ArrayList from the MBean in the table format using the <rich:dataTable> , all the white-spaces will be collapsed too.
Updated: I still think that it is specific to the JSF , because when I use<h:inputText value="#{MBean.test}"/> , the rendered input text box will collapse all the white-spaces.How can I preserve all the white-spaces in this case??

这不是 JSF 所特有的。这是特定于 HTML 的，
您可以通过将其放入 HTML
或者通过应用 CSS
white-space: pre：（如你看，它也出现在你在 Stackoverflow 上的问题上，因为它也不会通过

You can fix it by either putting it in a HTML
<pre>element:Or by applying CSS
