Fourth study: This study has been different from Struts1.1, that is, the Actionform class is more than just String type, which can be any data type. 1. Form entry (including bean nested). TestBean class, this class also contains a nested property (NESTED as an instance of a class), uses NESTED.BOOLEANPROPERTY to specify the position when setting the value for the BooleanProperty property attribute at the Nested class. The data is filled into TestBean and Nested.
