How to insert a new line between words for a backing bean value and display it on UI using JSF 2.0 framework? If we have address. The street name should be in first line and city and state should be in the second line. I am using a converter to add new line. But it does not show up on the UI.

推荐答案

JSF基本上是HTML代码生成器. HTML中的新行由<br />标记而不是\r\n字符或类似内容显示.您可以直接在视图中进行操作，而不必在托管Bean或转换器中混合特定于视图的详细信息.

JSF is basically a HTML code generator. A new line is in HTML to be presented by the <br /> tag, not by \r\n characters or something. You can just do it straight in the view instead of mingling view-specific details in the managed bean or a converter.

<h:outputText value="#{user.address.street} #{user.address.houseNumber}" />
<br />
<h:outputText value="#{user.address.city}, #{user.address.state}" />
