如何在没有Q类的情况下用QueryDSL删除？

// 引入QueryDSL依赖
// ...

// 创建实体类和查询对象
@Entity
@Table(name = "user")
public class User {
    @Id
    private Long id;
    private String name;
    // ...
}

public class QUser extends EntityPathBase<User> {
    public static final QUser user = new QUser("user");

    public QUser(String variable) {
        super(User.class, variable);
    }
}

// 构建查询条件
QUser qUser = QUser.user;
BooleanExpression condition = qUser.name.eq("John");

// 执行删除操作
JPAQueryFactory queryFactory = new JPAQueryFactory(entityManager);
queryFactory.delete(qUser).where(condition).execute();
