public class FileEncodingApplicationListener extends Object implements ApplicationListener<ApplicationEnvironmentPreparedEvent>, Ordered
ApplicationListener
that halts application startup if the system file
encoding does not match an expected value set in the environment. By default has no
effect, but if you set spring.mandatory_file_encoding
(or some camelCase
or UPPERCASE variant of that) to the name of a character encoding (e.g. "UTF-8") then
this initializer throws an exception when the file.encoding
System
property does not equal it.
The System property file.encoding
is normally set by the JVM in response
to the LANG
or LC_ALL
environment variables. It is used
(along with other platform-dependent variables keyed off those environment variables)
to encode JVM arguments as well as file names and paths. In most cases you can override
the file encoding System property on the command line (with standard JVM features), but
also consider setting the LANG
environment variable to an explicit
character-encoding value (e.g. "en_GB.UTF-8").
