Endpoint Options

The Thrift component supports 4 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
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
autowiredEnabled (advanced)	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
useGlobalSslContextParameters (security)	Determine if the thrift component is using global SSL context parameters	false	boolean

Thrift method parameters mapping

Parameters in the called procedure must be passed as a list of objects inside the message body. The primitives are converted from the objects on the fly. In order to correctly find the corresponding method, all types must be transmitted regardless of the values. Please see an exmaple below, how to pass different parameters to the method with the Camel body

List requestBody = new ArrayList();

requestBody.add((boolean)true);
requestBody.add((byte)THRIFT_TEST_NUM1);
requestBody.add((short)THRIFT_TEST_NUM1);
requestBody.add((int)THRIFT_TEST_NUM1);
requestBody.add((long)THRIFT_TEST_NUM1);
requestBody.add((double)THRIFT_TEST_NUM1);
requestBody.add("empty"); // String parameter
requestBody.add(ByteBuffer.allocate(10)); // binary parameter
requestBody.add(new Work(THRIFT_TEST_NUM1, THRIFT_TEST_NUM2, Operation.MULTIPLY)); // Struct parameter
requestBody.add(new ArrayList<Integer>()); // list paramater
requestBody.add(new HashSet<String>()); // set parameter
requestBody.add(new HashMap<String, Long>()); // map parameter

Object responseBody = template.requestBody("direct:thrift-alltypes", requestBody);

Incoming parameters in the service consumer will also be passed to the message body as a list of objects.

Thrift consumer headers (will be installed after the consumer invocation)

Header name	Description	Possible values
CamelThriftMethodName	Method name handled by the consumer service

Description

Possible values

CamelThriftMethodName

Examples

Below is a simple synchronous method invoke with host and port parameters

from("direct:thrift-calculate")
.to("thrift://localhost:1101/org.apache.camel.component.thrift.generated.Calculator?method=calculate&synchronous=true");

Below is a simple synchronous method invoke for the XML DSL configuration

<route>
    <from uri="direct:thrift-add" />
    <to uri="thrift://localhost:1101/org.apache.camel.component.thrift.generated.Calculator?method=add&synchronous=true"/>
</route>

Thrift service consumer with asynchronous communication

from("thrift://localhost:1101/org.apache.camel.component.thrift.generated.Calculator")
.to("direct:thrift-service");

It’s possible to automate Java code generation for .thrift files using thrift-maven-plugin, but before start the thrift compiler binary distribution for your operating system must be present on the running host.

Spring Boot Auto-Configuration

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