Examples with DefaultFileMonitor org.apache.commons.vfs2.impl.DefaultFileMonitor used on opensource projects

Example 1 with DefaultFileMonitor

use of org.apache.commons.vfs2.impl.DefaultFileMonitor in project motech by motech.

the class ConfigFileMonitor method init.

/**
 * Initializes the configuration file monitor. This method will be automatically called after creation and
 * dependency injection. It is done to make sure that injected dependencies are set and ready to use.
 */
@PostConstruct
public void init() throws IOException {
    BootstrapConfig bootstrapConfig = configurationService.loadBootstrapConfig();
    if (bootstrapConfig != null && bootstrapConfig.getConfigSource() == ConfigSource.FILE) {
        // allow custom monitors to be injected
        if (fileMonitor == null) {
            fileMonitor = new DefaultFileMonitor(this);
            // allow raw configs, which are one directory down, under /raw/, to be monitored
            fileMonitor.setRecursive(true);
        }
        fileMonitor.setDelay(DELAY);
        final List<File> files = new ArrayList<>();
        try {
            files.addAll(configLoader.findExistingConfigs());
        } catch (MotechConfigurationException ex) {
            LOGGER.error(ex.getMessage(), ex);
            return;
        }
        configurationService.processExistingConfigs(files);
        startFileMonitor();
    }
}

Example 2 with DefaultFileMonitor

use of org.apache.commons.vfs2.impl.DefaultFileMonitor in project accumulo by apache.

the class VfsClassLoaderTest method testFileMonitor.

@Test

    MyFileMonitor listener = new MyFileMonitor();
    DefaultFileMonitor monitor = new DefaultFileMonitor(listener);
    monitor.setRecursive(true);
    FileObject testDir = vfs.resolveFile(TEST_DIR.toUri().toString());
    monitor.addFile(testDir);
    monitor.start();
    // Copy jar file to a new file name
    URL jarPath = this.getClass().getResource("/HelloWorld.jar");
    Path src = new Path(jarPath.toURI().toString());
    Path dst = new Path(TEST_DIR, "HelloWorld2.jar");
    this.hdfs.copyFromLocalFile(src, dst);
