JSP pages use the Struts tab to report argument type mismatch exceptions __js

Error Description:
After using the

The result is that the date in the text box and the corresponding Java.util.Date type in the form will be quoted argument type mismatch

Abnormal.

Reason:
Actionservlet when a request is received to the page, the Requestutils.populate method is invoked to fill the form.

This method is called to the Beanutils.populate method, which converts different types of values when the method is filled in.

The default actionservlet does not register the corresponding conversion function, which causes the conversion to occur incorrectly

Solution:
Convert date type to string type in 1.ActionForm
The date type is still used in 2.ActionFrom, and a DateConverter class is customized (you need to implement

Converter interface), and then registers the DateConverter in a custom Actionservlet or action base class:

Convertutils.register (New DateConverter (), Date.class).
