Я пытаюсь создать простую папку Spring Integration для импорта данных. Но процесс выдает NoSuchFileException
при обработке последнего файла.
Я использую Spring 5.0.5 (и в этом демо Spring Boot 2.0.1)
Конфигурация
<bean id="dataImporter" class="com.example.demo.DataImporter" />
<bean id="XMLFileListFilter" class="org.springframework.integration.file.filters.SimplePatternFileListFilter" >
<constructor-arg value="*.xml" />
</bean>
<bean id="XMLFilter" class="org.springframework.integration.file.config.FileListFilterFactoryBean">
<property name="filter" ref="XMLFileListFilter" />
<property name="preventDuplicates" value="false" />
</bean>
<bean id="importFileComparator" class="com.example.demo.ImportFileComparator" />
<!--Input channel-->
<int-file:inbound-channel-adapter id="FilesInChannel"
directory="file:C:/Users/USER/Desktop/SI-Failing"
filter="XMLFilter"
auto-startup="true">
<int:poller fixed-rate="1000" time-unit="MILLISECONDS" max-messages-per-poll="1" />
</int-file:inbound-channel-adapter>
<!--Output channel-->
<int:recipient-list-router input-channel="FilesOutChannel"
default-output-channel="FilesOutSuccessChannel" >
<int:recipient channel="FilesOutFailureChannel" selector-expression="headers.containsKey('IMPORT_FAILURE')" />
</int:recipient-list-router>
<!--Success / Failure channel-->
<int-file:outbound-channel-adapter id="FilesOutSuccessChannel"
directory="file:C:/Users/USER/Desktop/SI-Failing/success/" delete-source-files="true"
filename-generator-expression="new java.text.SimpleDateFormat('yyyy-MM-dd_HH.mm.ss').format(new java.util.Date()) + '_' + payload.name"/>
<int-file:outbound-channel-adapter id="FilesOutFailureChannel"
directory="file:C:/Users/USER/Desktop/SI-Failing/error" delete-source-files="true"
filename-generator-expression="new java.text.SimpleDateFormat('yyyy-MM-dd_HH.mm.ss').format(new java.util.Date()) + '_' + payload.name"/>
<!--Verheiratung zwischen Importer, Input und Output-->
<int:service-activator
ref="dataImporter"
input-channel="FilesInChannel"
output-channel="FilesOutChannel" />
Это обработчик импорта:
public class DataImporter {
public Message<File> handleFileImport(Message<File> message) {
final File file = message.getPayload();
System.out.println("Processing file " + file);
return message;
}
}
И при помещении трех файлов XML в папку, это сообщение журнала будет генерироваться:

Кажется, что Spring пытается извлечь файл, который сам уже занесен в папку success
, поэтому не удается с NoSuchFileException
...
Что я делаю не так?
При необходимости я могу предоставить демонстрационное приложение Sping Boot: https://www.dropbox.com/s/7fwr9qi84c03u85/demo.7z?dl=0
