The Chinese log output by the terminal when Java is running jar is garbled

When running Jar, the Chinese logs output on the console are all garbled characters. This is because the default encoding of cmd/bash is GBK. Just change the encoding of cmd to UTF-8.

 Two ways to modify: temporary modification and registry permanent modification

Temporary modification

It is only valid for the current cmd page, and it will be restored to GBK after closing and reopening.

Open cmd and enter the following command

chcp 65001

In this way, the encoding of cmd can be changed to UTF-8.

The following are commonly used cmd codes

Character Encoding	corresponding character
GBK (default)	936
American English	437
utf-8	65001

At this time, we can specify the encoding parameters when running the Jar

java -Dfile.encoding=utf-8 -jar project.jar

It's back to normal now

For convenience, you can also modify the code and run the jar service into a bat file, and click to run it next time

chcp 65001

java -Dfile.encoding=utf-8 -jar project.jar

permanent modification

(1) win key + R, enter regedit , confirm

(2) Find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor in order

 (3) Right-click - New, select "String Value", name it "autorun", right-click to modify, fill in "chcp 65001" for the value data, and confirm

 Opening cmd at this time has defaulted to utf8

 There is no garbled code
