Java-JSF 2.0:和默认转换器
作者:互联网
我想为视图参数使用标准的JSF转换器(javax.faces.convert.DateTimeConverter)
从文档中:
You can refer to the converter by class or by its ID using the
component tag’s converter attribute. The ID is defined in the
application configuration resource file
然后,我尝试:
<f:viewParam
name = "rangeStartCreationDate"
value = "#{doiListController.model.rangeStartCreationDate}"
converter = "javax.faces.convert.DateTimeConverter"
/>
但我明白了
javax.faces.FacesException: Expression Error: Named Object: javax.faces.convert.DateTimeConverter not found.
然后,我尝试了第二个选项(按ID).我在faces-config.xml中定义了转换器
<converter>
<converter-id>DateTimeConverter</converter-id>
<converter-class>javax.faces.convert.DateTimeConverter</converter-class>
</converter>
并使用了ID
<f:viewParam
name = "rangeStartCreationDate"
value = "#{doiListController.model.rangeStartCreationDate}"
converterId = "DateTimeConverter"
/>
在这种情况下
Conversion Error setting value 'Tue Jul 24 00:00:00 CEST 2012' for 'null Converter'.
有没有办法让JSF实例化转换器,或者我必须手动实例化它(在某些bean中)?
解决方法:
转换器ID为javax.faces.DateTime,因此请尝试
<f:viewParam
converter="javax.faces.DateTime"
... />
