Tomcat 7 日志包含“-Dfile.encoding=Cp1252”：它来自哪里？

Question

I have a Tomcat 7.0.69 instance running inside Eclipse for Java (not JEE) 4.5.2 on Windows 10 - although I saw this on a JEE IDE or in other 7.0.x versions of Tomcat too.

When I start a server instance in debug mode, I have this line in the console view:

Informazioni: Command line argument: -Dfile.encoding=Cp1252

But I can't find any setting or preference that would add or change that parameter.

For completeness, I also have these

Informazioni: Command line argument: -Djdk.tls.client.protocols=TLSv1.1
Informazioni: Command line argument: -Dhttps.protocols=TLSv1.1,TLSv1.2

And both come from the server launch configuration Arguments tab, where for VM arguments I have:

-Dcatalina.base="C:\workspace-4.5.2-java\.metadata\.plugins\org.eclipse.wst.server.core\tmp2" -Dcatalina.home="C:\tools\tomcat\apache-tomcat-7.0.69" -Dwtp.deploy="C:\workspace-4.5.2-java\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\wtpwebapps" -Djava.endorsed.dirs="C:\tools\tomcat\apache-tomcat-7.0.69\endorsed"
-Djdk.tls.client.protocols=TLSv1.1
-Dhttps.protocols=TLSv1.1,TLSv1.2

These are my Java* env variables:

C:\Program Files (x86)\Windows Resource Kits\Tools>set java
JAVA_HOME=C:\Programmi\java\jdk1.7.0_51

(ie I have no JAVA_OPTS).

Any hint?

Answer 1

Since you're running Tomcat from Eclipse that's something it adds based on your default OS encoding. You can change it from the workspace preferences if you need to

Answer 2

You can find the setting in Common page of Run/Debug Configurations .
The default value is inherited from Text file encoding of workspace.
