PDF Component

Since Camel 2.16

Only producer is supported

The PDF components provides the ability to create, modify or extract content from PDF documents. This component uses Apache PDFBox as underlying library to work with PDF documents.

In order to use the PDF component, Maven users will need to add the following dependency to their pom.xml:

pom.xml

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

URI format

The PDF component only supports producer endpoints.

pdf:operation[?options]

Options

The PDF component supports 3 options, which are listed below.

Name Description Default Type

basicPropertyBinding (advanced)

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

bridgeErrorHandler (consumer)

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

The PDF endpoint is configured using URI syntax:

pdf:operation

with the following path and query parameters:

textProcessingFactory (producer)

Text processing to use. autoFormatting: Text is getting sliced by words, then max amount of words that fits in the line will be written into pdf document. With this strategy all words that doesn’t fit in the line will be moved to the new line. lineTermination: Builds set of classes for line-termination writing strategy. Text getting sliced by line termination symbol and then it will be written regardless it fits in the line or not.

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

Spring Boot Auto-Configuration

When using 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-pdf-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 4 options, which are listed below.

Name Description Default Type

camel.component.pdf.basic-property-binding

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

Boolean

camel.component.pdf.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.pdf.enabled

Whether to enable auto configuration of the pdf component. This is enabled by default.

Boolean

camel.component.pdf.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started.
