the set method was written. I think when struts gets the form parameters assembled into a user object, the assembled user object is set into action using the set method.But in the end, when I print the value of the user object passed in in the Set method, I find all the properties are the default values, and of course the user's value cannot be obtained in the Execute method.After this bug I guess (just guessing, not looking at the source code, if any big God knows please tell me) the call to t
