More clear error message when `select` entities with Builder but no default constructors [DATAJDBC-298]

[spring-projects-issues]

Yuxin Bai opened DATAJDBC-298 and commented

This is a many-to-many relationship that use IDs in a reference table to link two entities, Mirror and MirrorRequester. One of the entities MirrorRequester has a Set to represent one-to-many relationship with the reference table MirrorReference.

We are using Lombok @Builder in our codebase. When we do findAll() on MirrorRequester, we are getting this error: java.lang.IllegalStateException: Required identifier property not found for class com.sample.springdatajdbcschema.MirrorReference!.

This error goes away when we add @NoArgsConstructor(needed by spring-data-jdbc I assume) and @AllArgsConstructor(needed by lombok builder) to MirrorRequester alongside with @Builder.

 

Sample project here: https://github.com/LittleBaiBai/spring-data-jdbc-sample

Instead of adding lombok to the dependencies, I used the generated code in the sample project.

There are two commits, first one is the failing test commit without default constructor, and second one is passing with default constructor.
