Problem:Tomcat page displays garbled code, how to solve?

Solution:

Garbled Tomcat pages are usually caused by character encoding errors. To solve this problem, you need to check and correct the following settings:

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8" />

Among them, URIEncoding="UTF-8" specifies the character encoding of the requested data.

2. Check the response header

<code>Content-Type: text/html; charset=UTF-8</code>

where , charset=UTF-8 specifies the character encoding of the response content.

3. Check the JSP file

For JSP pages, you need to add the following lines at the top of the page:

<%@ page contentType="text/html; charset=UTF-8" %>
