我使用spring mvc和hibernate with annotation， 我在我的模块实体类
中有以下映射@OneToMany(cascade=CascadeType.ALL, fetch = FetchType.LAZY)
@JoinColumn(name="mp_mod_id")
private Set<ModulePermissionMpg> modulePermissionMpg;
//getter and setter
我的ModulePermissionsMpg实体类有
@ManyToOne(fetch = FetchType.LAZY)
private ModuleMst moduleMst;
如下
Hibernate: insert into a_modules (mod_created_date, mod_icon, mod_modified_date, mod_name, mod_status) values (?, ?, ?, ?, ?)
Hibernate: insert into a_module_permissions (moduleMst_mod_id, mp_created_by, mp_created_date, mp_mod_id, mp_modified_date, mp_perm_id, mp_status) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into a_module_permissions (moduleMst_mod_id, mp_created_by, mp_created_date, mp_mod_id, mp_modified_date, mp_perm_id, mp_status) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into a_module_permissions (moduleMst_mod_id, mp_created_by, mp_created_date, mp_mod_id, mp_modified_date, mp_perm_id, mp_status) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into a_module_permissions (moduleMst_mod_id, mp_created_by, mp_created_date, mp_mod_id, mp_modified_date, mp_perm_id, mp_status) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: update a_module_permissions set mp_mod_id=? where mp_id=?
Hibernate: update a_module_permissions set mp_mod_id=? where mp_id=?
Hibernate: update a_module_permissions set mp_mod_id=? where mp_id=?
Hibernate: update a_module_permissions set mp_mod_id=? where mp_id=?
这里的第一个问题是，“moduleMst_mod_id”这个额外的列被插入NULL。已经有一个名为mp_mod_id的列，其中包含mod_id。
第二个问题是当我尝试更新此表时删除2权限并在此模块中添加了1个新权限日志如下
insert into a_module_permissions (moduleMst_mod_id, mp_created_by, mp_created_date, mp_mod_id, mp_modified_date, mp_perm_id, mp_status) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: update a_modules set mod_created_date=?, mod_icon=?, mod_modified_date=?, mod_name=?, mod_status=? where mod_id=?
Hibernate: update a_module_permissions set moduleMst_mod_id=?, mp_created_by=?, mp_created_date=?, mp_mod_id=?, mp_modified_date=?, mp_perm_id=?, mp_status=? where mp_id=?
Hibernate: update a_module_permissions set moduleMst_mod_id=?, mp_created_by=?, mp_created_date=?, mp_mod_id=?, mp_modified_date=?, mp_perm_id=?, mp_status=? where mp_id=?
Hibernate: update a_module_permissions set mp_mod_id=null where mp_mod_id=?

当我尝试在我的模块实体类
中使用以下配置时@OneToMany(mappedBy="mp_mod_id", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Set<ModulePermissionMpg> modulePermissionMpg;
如下
Hibernate: insert into a_modules (mod_created_date, mod_icon, mod_modified_date, mod_name, mod_status) values (?, ?, ?, ?, ?)
Hibernate: insert into a_module_permissions (moduleMst_mod_id, mp_created_by, mp_created_date, mp_mod_id, mp_modified_date, mp_perm_id, mp_status) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into a_module_permissions (moduleMst_mod_id, mp_created_by, mp_created_date, mp_mod_id, mp_modified_date, mp_perm_id, mp_status) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into a_module_permissions (moduleMst_mod_id, mp_created_by, mp_created_date, mp_mod_id, mp_modified_date, mp_perm_id, mp_status) values (?, ?, ?, ?, ?, ?, ?)
Hibernate: insert into a_module_permissions (moduleMst_mod_id, mp_created_by, mp_created_date, mp_mod_id, mp_modified_date, mp_perm_id, mp_status) values (?, ?, ?, ?, ?, ?, ?)
在这个问题中，mp_mod_id将被插入0.即映射表在模块表中没有新插入模块的id。
但是当我尝试像上面那样更新时，它的工作非常完美。
这里有什么问题？！？
编辑： ModuleMst.java
@OneToMany(cascade=CascadeType.ALL, fetch = FetchType.LAZY)
@JoinColumn(name="mp_mod_id")
private Set<ModulePermissionMpg> modulePermissionMpg;
ModulePermissionMpg.java
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="mp_mod_id", insertable=false, updatable=false)
private ModuleMst moduleMst;
使用它可以在插入时工作，但是当我进行查询以获取具有该特定mod_id的权限时，它会产生以下错误
Hibernate: select moduleperm0_.mp_id as mp_id1_3_, moduleperm0_.mp_mod_id as mp_mod_i4_3_, moduleperm0_.mp_created_by as mp_creat2_3_, moduleperm0_.mp_created_date as mp_creat3_3_, moduleperm0_.mp_modified_date as mp_modif5_3_, moduleperm0_.mp_perm_id as mp_perm_6_3_, moduleperm0_.mp_status as mp_statu7_3_ from a_module_permissions moduleperm0_ where moduleperm0_.mp_status<>? and moduleperm0_.mp_mod_id=?
