Example of how to solve Chinese garbled characters in jsp value passing

In jsp, we often read data from the database and return data to the client, but we often encounter garbled characters during production, so we can use <% request. setCharacterEncoding ("UTF-8"); %> This method ensures the correct output of Chinese characters. Here is an example,
Before we capture the form value or print the database data, we need to <% request. setCharacterEncoding ("UTF-8"); %> put in front of them, then the form must be submitted in post, that is, method = "post", so that you can close to avoid garbled, see the following:
Copy codeThe Code is as follows:
<% Request. setCharacterEncoding ("UTF-8"); %>
<Form action = "" method = "post">
Name: <input type = "text" name = "name"/>
<Br/>
Gender: <input type = "text" name = "sex"/>
<%
String name = requset. getParameter ("name ");
String sex = request. getParameter ("sex"); out. print (name );
Out. print (sex );
%>
</Form>

Or sometimes, when a user logs in, we need to use the user name or password on a page. We can use the following method to remember that other pages can be called at will, for example:
Copy codeThe Code is as follows:
<Form action = "" method = "post">
Username: <input type = "text" name = "name"/>
<Br/>
Password: <input type = "password" name = "password"/>
<Form/>
String name = requset. getParameter ("name ");
String password = request. getParameter ("password ");
Application. setAttribute ("names", name );
Application. setAttribute ("passwords", password); the password and user name can be remembered. You can also call them as needed, as shown below:
Application. getAttribute ("names ");
Application. getAttribute ("passwords ");
<%
Out. print (application. getAttribute ("names "));
Out. print (application. getAttribute ("passwords ")
%>

In this way, the value of the text box is output.
