示例1: setupSystemState
import org.python.core.Py; //导入方法依赖的package包/类
/**
* Call to ensure that an interpreter is set up and configured and
* able to load the relevant bundles.
*/
public static synchronized void setupSystemState(String... bundleNames) {
ClassLoader loader=null;
if (configuredState==null) { // Relies on setupSystemState() being called early in the server startup.
loader = createJythonClassLoader(PySystemState.class.getClassLoader());

}

if (state==configuredState) return;
if (loader==null) {
// Then someone else has changed the PySystemState
// They will not have added our
loader = createJythonClassLoader(state.getClassLoader()); // Don't clobber their working.
}

setJythonPaths(state); // Tries to ensure that enough of jython is on the path
setSpgGeneratorPaths(state, bundleNames); // Adds the scripts directory from points
