Platform HTTP

Since Camel 3.0

Only consumer is supported Since Camel 3.0

The Platform HTTP is used to allow Camel to use the existing HTTP server from the rumtime. For example when running Camel on Spring Boot, Quarkus, or other runtimes.

Maven users will need to add the following dependency to their pom.xml for this component:

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

Options

The Platform HTTP component supports 3 options, which are listed below.

Name Description Default Type

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

basicPropertyBinding (advanced)

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

false

boolean

engine (advanced)

An HTTP Server engine implementation to serve the requests

PlatformHttpEngine

The Platform HTTP endpoint is configured using URI syntax:

platform-http:path

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

path

Required The path under which this endpoint serves the HTTP requests

String

Query Parameters (12 parameters):

Name Description Default Type

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

consumes (consumer)

The content type this endpoint accepts as an input, such as application/xml or application/json. null or */* mean no restriction.

String

httpMethodRestrict (consumer)

A comma separated list of HTTP methods to serve, e.g. GET,POST . If no methods are specified, all methods will be served.

String

matchOnUriPrefix (consumer)

Whether or not the consumer should try to find a target consumer by matching the URI prefix if no exact match is found.

false

boolean

produces (consumer)

The content type this endpoint produces, such as application/xml or application/json.

String

exceptionHandler (consumer)

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.

ExceptionHandler

exchangePattern (consumer)

Sets the exchange pattern when the consumer creates an exchange. The value can be one of: InOnly, InOut, InOptionalOut

ExchangePattern

fileNameExtWhitelist (consumer)

A comma or whitespace separated list of file extensions. Uploads having these extensions will be stored locally. Null value or asterisk () will allow all files.

String

basicPropertyBinding (advanced)

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

false

boolean

headerFilterStrategy (advanced)

To use a custom HeaderFilterStrategy to filter headers to and from Camel message.

HeaderFilterStrategy

platformHttpEngine (advanced)

An HTTP Server engine implementation to serve the requests of this endpoint.

PlatformHttpEngine

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 platform-http 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-platform-http-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.platform-http.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.platform-http.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.platform-http.enabled

Whether to enable auto configuration of the platform-http component. This is enabled by default.

Boolean

camel.component.platform-http.engine

An HTTP Server engine implementation to serve the requests. The option is a org.apache.camel.component.platform.http.spi.PlatformHttpEngine type.
