Spring Data JPA – “No Property Found for Type” Exception

by

I ran into this same issue and found the solution here: https://dzone.com/articles/persistence-layer-spring-data

I had renamed an entity property. But with Springs Automatic Custom Queries there was an interface defined for the old property name.

public interface IFooDAO extends JpaRepository< Foo, Long >{
     Foo findByOldPropName( final String name );
}

The error indicated that it could no longer find OldPropName and threw the exception.

To quote the article on DZone:

When Spring Data creates a new Repository implementation, it analyzes all the methods defined by the interfaces and tries to automatically
generate queries from the method name. While this has limitations, it
is a very powerful and elegant way of defining new custom access
methods with very little effort. For example, if the managed entity
has a name field (and the Java Bean standard getter and setter for
that field), defining the findByName method in the DAO interface will
automatically generate the correct query:

public interface IFooDAO extends JpaRepository< Foo, Long >{
     Foo findByName( final String name );
}

This is a relatively simple example; a much larger set of keywords is supported by query creation mechanism.

In the case that the parser cannot match the property with the domain object field, the following exception is thrown:

java.lang.IllegalArgumentException: No property nam found for type class org.rest.model.Foo
