/**

* properties file. This model is often more flexible and more amenable to creating
|
||||
* well-behaved OS-level services than a model based on executable jars.
|
||||
* <p>
|
||||
* Looks in various places for a properties file to extract loader settings, defaulting to
|
||||
* {@code loader.properties} either on the current classpath or in the current working
|
||||
* directory. The name of the properties file can be changed by setting a System property
|
||||
* {@code loader.config.name} (e.g. {@code -Dloader.config.name=foo} will look for
|
||||
* {@code foo.properties}. If that file doesn't exist then tries
|
||||
* {@code loader.config.location} (with allowed prefixes {@code classpath:} and
|
||||
* {@code file:} or any valid URL). Once that file is located turns it into Properties and
|
||||
* extracts optional values (which can also be provided overridden as System properties in
|
||||
* case the file doesn't exist):
|
||||
* <ul>
|
||||
* <li>{@code loader.path}: a comma-separated list of directories (containing file
|
||||
* resources and/or nested archives in *.jar or *.zip or archives) or archives to append
|
||||
* to the classpath. {@code BOOT-INF/classes,BOOT-INF/lib} in the application archive are
|
||||
* always used</li>
|
||||
* <li>{@code loader.main}: the main method to delegate execution to once the class loader
|
||||
* is set up. No default, but will fall back to looking for a {@code Start-Class} in a
|
||||
* {@code MANIFEST.MF}, if there is one in <code>${loader.home}/META-INF</code>.</li>
