Question

实体的一部分：

public class Shortcut extends IRepositoryObject {

..
    @ManyToOne(fetch = FetchType.LAZY, optional=true, cascade=CascadeType.REFRESH)
    @JoinColumnsOrFormulas({
    @JoinColumnOrFormula(formula=@JoinFormula(value=CONTENT_ID_FIELD, referencedColumnName=UUID))
    })
    private Content providerContent;
}

我有一个代码：

    Shortcut shortcut = basicRepository.findOne(Shortcut.class, 407);
    log.info("get provider");
    log.info("provider content: {}", shortcut.getProviderContent());

并记录：

为什么LAZY sql查询不起作用???

为什么JoinColumnsOrFormulas和LAZY不起作用？
