Depending on your bean, you might have some ambiguity. Camel gives you fine-grained control of the method parameters by providing a set of annotations.

Thanks to the annotations, you can describe the expected binding for both method binding and parameter binding.

For method binding, Camel provides the @Handler annotation. This annotation allows you to specify the method that Camel will use during execution.

For instance, you may have the following bean:

public class MyBean {
  public void other(String class) {  }

public void doMyStuff(String class) { ... }
}

In that case, Camel (without specifying the method to use in the route definition) will fail to find the method to call.

The @Handler annotation removes the ambiguity:

public class MyBean {
  public void other(String class) { … }
  @Handler
public void doMyStuff(String class) { ... }
}

Camel also provides annotations for the method parameters binding. The @Body binds the parameter to the in message body. It allows to bind type like...
