This article introduces the relevant knowledge of "how to solve the problem of garbled code on the server side and front end of JSP". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

In the process of the interaction between the front end and the server, the interaction is mainly through the HTTP protocol, and a HttpServlet class is provided in the Servlet interface to create the Servlet applied to the HTTP protocol.

Two classes, ServletRequest and ServletResponse, are provided in the Servlet container to obtain and send data through the objects of these two classes. At this point, we know that if we need to set the encoding format, then we need to set the encoding format twice.

Once is to set the encoding format of the data received by the server:

Request.setCharacterEncoding ("utf8")

The other time is to set the encoding format in which the server sends data to the front end:

Response.setContentType ("TEXT/HTML;charset=utf-8")

In this way, the problem of garbled code can be solved when the input and output coding formats are set. In addition, the request and response objects here are obtained through two parameters in the servlet () method of the Servlet class, because both ServletRequest and ServletResponse classes are abstract classes, so there is no way to instantiate them directly.
