Encoding Problems-there are three types of codes (page encoding, file format encoding, and backend encoding)

The solution is: three encoding is unified and all are handled in UTF-8.

 

Set the project first

Set the -- JSP encoding format, or delete it. modify it in notepad and save it as JSP UTF-8.

When processing is finally accepted, set the next character

Request. setcharacterencoding ("UTF-8 ");
Response. setcharacterencoding ("UTF-8 ");

 

Last OK

 

 

Record it. I think this is the purpose of the Interceptor. There are too many things to learn. J2EE is not simple.
