Example of solution to the problem of jsp value transmission Chinese garbled code

In jsp, we often read data from the database and return to the client, but we often experience garbled code during production, so we can use <%("UTF-8");%> to ensure the correct output of Chinese. Let's give an example below.
Before we want to catch the value of the form or print the database data, put <%("UTF-8");%> in front of them. Then, the form must be submitted by post, that is, method="post", so that it can avoid garbled code. Please see below:

Copy the codeThe code is as follows:

 
<%("UTF-8");%> 
<form action="" method="post"> 
Name: <input type="text" name="name"/>
<br/> 
Gender: <input type="text" name="sex" />
<% 
String name=("name"); 
String sex=("sex");(name); 
(sex); 
%> 
</form> 

Or sometimes when a user logs in, we need to use the user name or password on a certain page. We can remember it by using the following method. You can call it at will on other pages, such as:

Copy the 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=("name"); 
String password=("password"); 
("names",name); 
("passwords",password); Password and username are remembered in this way, and can also be called at will, as follows
(“names"); 
("passwords"); 
<% 
((“names")); 
((“passwords") 
%> 

This will output the value of the text box
