Spring Data query from method doesn't recognize column
hibernate, spring-data
Solution
The query derivation mechanism requires standard Java property naming conventions to be applied. There's no property `createdDate` as it's called `CreatedDate` in your class.
To customize the mapping to a certain column, use the `@Column` annotation (hence the name).
Problem
I am using Spring Data, I have created my entities wrapped inside of an "AbstractEntity" which all objects extend to get basic columns AbstractEntity: ``` @MappedSuperclass public abstract class AbstractEntity implements Serializable{ @Temporal(TemporalType.TIMESTAMP) @Column(nullable = false) private Date CreatedDate; @PrePersist protected void onCreate() { UpdatedDate = CreatedDate = new Date(); } ... ``` And my Object/Entity ``` @Entity public class Trade extends AbstractEntity { ``` When I attempt to use my repository to create a method to `findByCreatedDateAfter(Date date)` I get an exception that the column can't be found...? ``` public interface TradeRepository extends CrudRepository<Trade, Long>{ public List<Trade> findByCreatedDateAfter(Date date); } ``` It compiles (if I use certain capitolization) but than attempting to map the query, I get: ``` Caused by: java.lang.IllegalArgumentException: Unable to locate Attribute with the given name [createdDate] on this ManagedType [streaming.data.AbstractEntity] ``` I also would like to return the `sum(amount)` of one of the amount column for this period.
