无法解决财产问题

Question

我加入了两个表。我希望通过添加一些分离的标准来检索数据，但它显示＆＃34;无法解析属性＆＃34;错误。

＆＃34; userMaster＆＃34;表：

数据访问标准：

DetachedCriteria criteria = DetachedCriteria.forClass(UserDetailedTbl.class);
criteria.add(Expression.in("userMasterTbl.status", userRoles))

Answer 1

我认为这里的问题是，在UserDetailedTbl类中，您使用的是主键ID和类UserMasterTbl中的外键的相同名称ID，您可以在此处查看：

@Column(name="ID") // Used 'ID' here
private Integer id;


//And then 
@OneToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
@JoinColumn(name="ID") // And Used 'ID' here
private UserMasterTbl userMasterTbl ;

更改JoinColumn值的名称，可能是：

@JoinColumn(name="MasterUserID")

注意：

如this link中所述，由GK27在评论中提供，请确保您已编写了所有获取者和设置者并且遵守惯例。

Answer 2

在您粘贴的代码中，status类中的UserMasterTbl属性没有getter和setter。您需要为hibernate映射实体的所有非瞬态属性设置getter和setter。
