Question

I have the following code :

@Data
@NoArgsConstructor
public class Script {

    @Id
    private UUID id;

    @Version
    private int version;

    @NonNull
    private String name;

    @Embedded(onEmpty = OnEmpty.USE_EMPTY)
    List<ScriptArg> scriptArgs;

    public Script(String name, List<ScriptArg> scriptArgs) {
        this.name = name;
        this.scriptArgs = scriptArgs;
    }
}

@Data
@NoArgsConstructor
public class ScriptArg {
    @NonNull
    private String name;

    @NonNull
    private String type;

    private boolean optional = false;
}

When I try to save a “Script” entity using a CrudRepository of Spring JDBC, I get an exception :

    Failed to execute InsertRoot{entity=Script(id=null, version=1, name=First Script, scriptArgs=[ScriptArg(name=TheArg1, type=String, optional=false), ScriptArg(name=TheArg2, type=int, optional=false)]), idValueSource=GENERATED}

However Spring’s documentation say : “Embedded entities containing a Collection or a Map will always be considered non empty since they will at least contain the empty collection or map. Such an entity will therefore never be null even when using @Embedded(onEmpty = USE_NULL).”

So, I assume that using a embedded list of entites should be possible. Where am I wrong ?

Thanks 🙂
