Camel Spring Boot Starter for file-watch

Spring Boot Auto-Configuration

When using file-watch with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-file-watch-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 8 options, which are listed below.

Name Description Default Type

camel.component.file-watch.bridge-error-handler

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

Boolean

camel.component.file-watch.concurrent-consumers

The number of concurrent consumers. Increase this value, if your route is slow to prevent buffering in queue.

1

Integer

camel.component.file-watch.enabled

Whether to enable auto configuration of the file-watch component. This is enabled by default.

Boolean

camel.component.file-watch.file-hasher

Reference to io.methvin.watcher.hashing.FileHasher. This prevents emitting duplicate events on some platforms. For working with large files and if you dont need detect multiple modifications per second per file, use #lastModifiedTimeFileHasher. You can also provide custom implementation in registry. The option is a io.methvin.watcher.hashing.FileHasher type.

String

camel.component.file-watch.poll-threads

The number of threads polling WatchService. Increase this value, if you see OVERFLOW messages in log.

1

Integer

camel.component.file-watch.queue-size

Maximum size of queue between WatchService and consumer. Unbounded by default.

Integer

camel.component.file-watch.use-file-hashing
