PersistenceConstructor argument variable name doesn't match instance variable name
I'm trying to persist the following object with spring-data-mongodb version 1.1.1.RELEASE:
Code:
@Document
public static class TestObject {
private final int m_property;
@PersistenceConstructor
public TestObject(int a_property) {
m_property = a_property;
}
public int property() {
return m_property;
}
}
I get a MappingException when I try to read the object back from the database:
No property a_property found on entity class com.recorder.TestRecorder$TestObject to bind constructor parameter to!
The naming convention my group uses requires argument variable names to be prefaced by "a_" and instance variable names to be prefaced by "m_". It seems like spring-data-mongodb is making the assumption that the constructor argument variable names must match the object instance variable names.
Why doesn't spring-data-mongodb use the constructor argument to instance variable mapping that I define within the constructor? Is there another way to define this mapping such that spring-data-mongodb will properly construct my object, or is my only option to break the naming convention?
Code:
Exception in thread "main" org.springframework.data.mapping.model.MappingException: No property a_property found on entity class com.recorder.TestRecorder$TestObject to bind constructor parameter to!
