In the example above it uses Apache Commons IO WildcardFilter as it implements FileFilter. The Apache Commons IO jar file must be in the classpath. See: http://commons.apache.org/io/
Comparators
You can define an implementation of the java.util.Comparator interface to specifies the process order of the files.
For example, you can process file sorted by file name. You can implement the following comparator:
| Code Block |
|---|
| lang | java |
|---|
| title | NameComparator |
|---|
|
public class NameComparator implements Comparator<File> {
/*
* (non-Javadoc)
* @see java.util.Comparator#compare(java.lang.Object, java.lang.Object)
*/
public int compare(File file1, File file2) {
return file1.getPath().compareTo(file2.getPath());
}
}
|
and use it in the endpoint definition:
| Code Block |
|---|
| lang | xml |
|---|
| title | XBean using NameComparator |
|---|
|
<file:poller service="test:poller" endpoint="poller"
file="file:inbox" targetService="test:service"
targetEndpoint="endpoint" period="10000" recursive="true">
<property name="comparator">
<bean class="your.package.NameComparator"/>
</property>
</file:poller>
|
Like this, you can process file by name, last modification date, size.
Marshalers
By default, poller endpoints expect the content of the file to be in xml format.
