First, IntroductionDescription: The HTTP protocol transmits data without the concept of type, on the server side is the Request.getparameter (), Request.getparametervalue () method to get the request parameter to a String or string[] type.However, this is inconvenient to use, we hope that the open source framework can automatically complete the type conversion, to use the direct access to the target type.Second, Struts2 type conversion1. STRUTS2 itself completes the automatic conversion of the s

Userlog class. In this way, other classes can use the Userlog class, and you can test it without an ASP.The implementation of the intercepting Filter pattern has the following advantages and disadvantages:Advantages1. Use event-driven filters. The ASP. NET runtime provides a number of events, which allows the programmer to hook up to the appropriate location to add functionality. This is an advantage because the programmer can assume the current state of the request based on the event. For exam
