Configuration
Settings Properties
Properties can be set by:
- java code (highest precedence)
- system property
- property file
- environment property (lowest precedence)
The order of precedence means that properties set by java code overrides those set by system properties which overrides property file properties which overrides environment variables.
Some properties need to be set before MockServer starts because they are only read at start-up, for example, nioEventLoopThreadCount.
Other values are read continuously and so can be changed at any time, for example, logLevel.
Property File
The property file defaults to filename mockserver.properties in the current working directory of MockServer.
This location of the property file can be changed by setting the mockserver.propertyFile system property or MOCKSERVER_PROPERTY_FILE environment property, for example:
-Dmockserver.propertyFile=/config/mockserver.propertiesAn example properties file can be found in github, as follows:

Liveness Configuration:
Path to support HTTP GET requests for status response (also available on PUT /mockserver/status).
