RBAC的數據庫建立

一、數據庫，參照網上一些範例，在mysql中創建以下表

-- Create the datatable named by 
'RBAC_User'
 to save users.
create table RBAC_User
(

 User_ID int
 primary key auto_increment,

 User_Name varchar(20
) not 
null
,

) not 
null
,

 User_Lock bit not null
);

CREATE UNIQUE INDEX IDX_User ON  RBAC_User(User_Name) ;

-- Create the datatable named by 'RBAC_Group'
 to save groups.
create table RBAC_Group
(

 Group_ID int
 primary key auto_increment,

null

CREATE UNIQUE INDEX IDX_Permission ON RBAC_Permission (Role_ID, Authority_ID);

二、用myEclipse生成pojo、dao後，對hbm.xml的配置部分修改，繞過只起關聯關係的表，改爲把兩個一對多改爲一個多對多。

//RbacGroup.hbm.xml
         <set name="rbacUsers"
 table=
"rbac_user_group"
 inverse=
"true"
 lazy=
"true"
 cascade=
"save-update"
>
            <key>
                <column name="Group_ID"
 not-
null
=
"true"
 />
            </key>
            <many-to-many class
=
"dao.rbac.RbacGroup"
 column=
"User_ID"

        </set>
        <set name="rbacRoles"
 table=

 inverse=

 cascade=

>
            <key>
                <column name="Group_ID"

            </key>

            </key>
            <many-to-many class

        </set>

//RbacRole.hbm.xml
         <set name="rbacGroups"

            </key>
            <many-to-many class
=
"dao.rbac.RbacRole"
 column=
"Group_ID"
 />
        </set>

//RbacGroup.hbm.xml
         <set name="rbacUsers" table="rbac_user_group" inverse="true" lazy="true" cascade="save-update">
            <key>
                <column name="Group_ID" not-null="true" />
            </key>
            <many-to-many class="dao.rbac.RbacGroup" column="User_ID" />
        </set>
        <set name="rbacRoles" table="rbac_group_role" inverse="true" lazy="true" cascade="save-update">
            <key>
                <column name="Group_ID" not-null="true" />
            </key>
            <many-to-many class="dao.rbac.RbacGroup" column="Role_ID" />
        </set>
//RbacUser.hbm.xml
         <set name="rbacGroups"  table="rbac_user_group" inverse="false" lazy="true" cascade="save-update">
            <key>
                <column name="User_ID" not-null="true" />
            </key>
            <many-to-many class="dao.rbac.RbacUser" column="Group_ID" />
        </set>

//RbacRole.hbm.xml
         <set name="rbacGroups" table="rbac_group_role" inverse="false" lazy="true" cascade="save-update">
            <key>
                <column name="Role_ID" not-null="true" />
            </key>
            <many-to-many class="dao.rbac.RbacRole" column="Group_ID" />
        </set>

三、pojo中集合屬性的修改，和以上配置保持一致，略...
