I am using camel-bindy version 3.8.0 and I'm hitting a null pointer exception
because bindy selects the key-value pair format and ignores the annotated
format type and XML-defined format when the model class is annotated with the
Spring @Value annotation or if the XML bean definition contains property
elements.
Model class:
@FixedLengthRecord(length=103)
public class MyModelClass {
@DataField(pos = 1, length = 2)
private String constantField;
@DataField(pos = 3, length = 5)
private String variableField;
...
Constructor and getters/setters
}
XML model bean definition
<bean id="chipsInMessage"
class="org.theclearinghouse.isomessaging.model.ChipsInMessage">
<property name="constantField" value="aConstantValue"/> </bean>
XML bindy route
<route id="inputMarshallingRouter">
<from uri="direct:inputMarshallingModule"/>
<marshal>
<bindy type="FixedLengthRecord" allowEmptyStream="false"
classType="MyModelClass"/>
</marshal>
<to uri="next:endpoint"/>
</route>
Exception
java.lang.NullPointerException: null
