How to deal with garbled characters in tomcat

Tomcat garbled code problem can be solved by the following steps: check whether the URIEncoding setting in server.xml is correct; set Java encoding to the target character set; check whether the HTTP request header has an "Accept-Charset" header field; confirm the database connection Use the correct character set; specify "Content-Type" and the character set in the Tomcat response header; for static resources, use to specify the character set.

How to solve the Tomcat garbled code problem

Question: Tomcat has garbled code, how to solve it?

Solution:

Solving the problem of Tomcat garbled characters is mainly divided into the following steps:

1. Check the Character Encoding setting

• In the Tomcat configuration file server.xml, find the <connector></connector> element and check the URIEncoding attribute.
• Make sure this property is set to the target character set, such as "UTF-8".

2. Check the Java Encoding setting

• In Java code, passSystem.setProperty("file.encoding", " UTF-8") Set Java encoding.
• This will ensure that Java uses the correct character set to read and write files.

3. Check the HTTP request header

• Check whether there is an "Accept-Charset" header field in the HTTP request header.
• Make sure this header contains the target character set, such as "utf-8".

4. Check the database connection

• If Tomcat obtains data from the database, please check whether the database connection uses the correct character set.
• Typically, the character set can be specified via the characterEncoding parameter in the JDBC URL.

5. Check the Response Header

• In the Tomcat response, add the "Content-Type" header and specify the character set, such as "text/ html; charset=UTF-8".

6. Check for static resources

• For static resources (such as HTML files), make sure to use <meta charset="UTF -8"> Meta tag specifies the character set.

Example:

The following is an example of setting Character Encoding in the server.xml configuration file:

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

By following these steps, garbled characters in Tomcat can usually be resolved. Please adjust according to the specific situation.
