Java记录- QueryDSL

Question

我想将Java与mongoDB & querydsl结合使用。然而，似乎querydsl APT引起了一个问题。当我试图处理简单代码(一个记录和一个普通类)时：

@QueryEntity
public class TestClass implements Persistable<UUID> {
    @Override
    public UUID getId() {
        return null;
    }

    @Override
    public boolean isNew() {
        return false;
    }
}

@QueryEntity
public record TestRecord() implements Persistable<UUID> {
    @Override
    public UUID getId() {
        return null;
    }

    @Override
    public boolean isNew() {
        return false;
    }
}

结果是：

/**
 * QTestClass is a Querydsl query type for TestClass
 */
@Generated("com.querydsl.codegen.DefaultEntitySerializer")
public class QTestClass extends EntityPathBase<TestClass> {

    private static final long serialVersionUID = -1582647675L;

    public static final QTestClass testClass = new QTestClass("testClass");

    public final ComparablePath<java.util.UUID> id = createComparable("id", java.util.UUID.class);

    public final BooleanPath new$ = createBoolean("new");

    public QTestClass(String variable) {
        super(TestClass.class, forVariable(variable));
    }

    public QTestClass(Path<? extends TestClass> path) {
        super(path.getType(), path.getMetadata());
    }

    public QTestClass(PathMetadata metadata) {
        super(TestClass.class, metadata);
    }

}

/**
 * QTestRecord is a Querydsl query type for TestRecord
 */
@Generated("com.querydsl.codegen.DefaultEntitySerializer")
public class QTestRecord extends EntityPathBase<TestRecord> {

    private static final long serialVersionUID = -1394409244L;

    public static final QTestRecord testRecord = new QTestRecord("testRecord");

    public final org.springframework.data.domain.QPersistable _super = new org.springframework.data.domain.QPersistable(this);

    public final ComparablePath<java.util.UUID> id = createComparable("id", java.util.UUID.class);

    public final BooleanPath new$ = createBoolean("new");

    public QTestRecord(String variable) {
        super(TestRecord.class, forVariable(variable));
    }

    public QTestRecord(Path<TestRecord> path) {
        super(path.getType(), path.getMetadata());
    }

    public QTestRecord(PathMetadata metadata) {
        super(TestRecord.class, metadata);
    }

}

但是在处理过程中，我收到了：找不到由这一行引起的符号：

public final org.springframework.data.domain.QPersistable _super = new org.springframework.data.domain.QPersistable(this);

只在QTestRecord。为什么记录和班级有区别？非常感谢！

PS: querydsl配置：
