[Springframework-developer] Trimming values in PropertiesBeanDefinitionReader

[Bram S. <br...@in...>]

Hi All,

This week, at a customer, I encountered some annoying behavior with the
ResourceBundleViewResolver.

When the view class, specified in the properties file, contains a trailing
whitespace in the class name, you get a ClassNotFoundException with the
message:
java.lang.ClassNotFoundException:
org.springframework.web.servlet.view.InternalResourceView

This proved to be very confusing to developers (as I reckon it is, as the
whitespace is not visible in the error message). The problem lies in the
fact that the PropertiesBeanDefinitionReader does not trim the values
obtained from the resource bundle.

Is it possible to add trimming of the values in the resource bundles, or do
I miss some implications this might have?

It is fairly simple to test, I just added another test to the
ResourceBundleViewResolverTests that checks for an additional view (with a
trailing whitespace in the class name).

Greetings,
Bram Smeets
