How to solve tomcat startup garbled code

Solutions to garbled Tomcat startup: 1. Modify Tomcat's conf configuration file; 2. Modify the system language; 3. Modify the command line window encoding; 4. Check the Tomcat server configuration; 5. Check the project encoding; 6 , Check the log file; 7. Try other solutions. Detailed introduction: 1. Modify Tomcat's conf configuration file, open Tomcat's conf directory, find the "logging.properties" file, etc.

The operating system for this tutorial: Windows 10 system, DELL G3 computer.

The Tomcat startup garbled problem may be caused by a variety of reasons, such as incorrect system language settings, incorrect Tomcat configuration file encoding settings, incorrect command line window encoding settings, etc. The following are some steps and methods to solve the garbled problem of Tomcat startup:

1. Modify Tomcat's conf configuration file:Open Tomcat's conf directory, find the "logging.properties" file, and change the file Change all "encoding=UTF-8" in to "encoding=GBK". After saving, restart the Tomcat server.

2. Modify the system language:In Windows systems, you can try to modify the system language to solve the problem of garbled characters. The specific steps are: Open Control Panel, select Clock and Region, and then click Change Date and Time. In the Regional tab, set the system language to Chinese (Simplified, China) and restart the computer.

3. Modify the command line window encoding:In Windows systems, you can permanently change the character encoding of the command line window by modifying the registry. The specific steps are: Press the Win R key and enter regedit to open the registry editor. Then navigate to the following path: Computer\HKEY_CURRENT_USER\Console. If you do not see the Console item, you can create a new item named Console at this location. Next, create a new 32-bit value named CodePage under the Console item and set its data to the required encoding value. For example, setting it to 936 means GBK encoding, and setting it to 65001 means UTF-8 encoding. Finally, restarting the computer can permanently solve the problem.

4. Check the Tomcat server configuration:Check whether the character set settings in the Tomcat server configuration file (such as server.xml) are correct. Make sure the character set setting of the Tomcat server configuration file is consistent with the project encoding.

5. Check the project encoding:If there are multiple encoding methods in the project, it may cause garbled code problems. Make sure the encoding used in the project is consistent, and try to use common encodings, such as UTF-8 or GBK.

6. Check the log file:Check the Tomcat log file (such as catalina.out) and check whether there is any garbled code problem. If there are garbled characters, you can troubleshoot and solve them based on the error information in the log file.

7. Try other solutions:If none of the above methods solve the problem, you can try other solutions, such as reinstalling the Tomcat server, checking the firewall and anti-virus software settings, etc.

In short, solving the Tomcat startup garbled problem requires comprehensive consideration of multiple factors, including system language, Tomcat configuration file, command line window encoding, project encoding, etc. In the process of solving the garbled code problem, you need to pay attention to maintaining the consistency of character encoding between the system and the application to avoid other garbled code problems.
