Embodiment
Basic conception of the present invention is, in web application, by carrying out classification, grouping management to user and resource, for each user arranges the group coding of the group mark of at different levels groups comprised belonging to it, and be that immediate subordinate arranges group coding for described resource in certain group by needing the resource distribution of granted access, make user when accessing described resource, the group coding organized belonging to the resource will accessed by inspection is authorized the resource that user will access, thus realizes the fail safe of resource data management.
Fig. 1 illustrates the overall procedure schematic diagram processing HTTP request in web application.Shown in Fig. 1 is the process responding HTTP request under Spring MVC framework.
With reference to Fig. 1, pre-configured preposition controller (Dispatcher Servlet) receives the access request (request) of user, corresponding handling procedure (controller is found by map controller (Handler Mapping), Controller), and transfer this handling procedure work, carry out request process, after processing, model and view name are returned to preposition controller (Dispatcher Servlet), after preposition controller (Dispatcher Servlet) receives model and view name, view resolver (ViewResolver) can find view object (View according to view name, view object respective view file, which determine the ways of presentation of model data), view object is played up model data according to view file, and response is to user (response).
Handling procedure (controller, Controller) is responsible for the control of concrete business module flow process, and the interface that call Service layer carrys out service control flow process, and the business realizing of Service layer, call the interface of defined DAO layer.
According to exemplary embodiment of the present invention, by at handling procedure (controller, Controller) aspect increases blocker, interception input and output object, obtain the place tissue of operating data and the place tissue of login user, judge that can login user access or operate input and output object (resource data), thus realize the control of authority of resource access.Such as, blocker can be configured as follows:
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**"/>
<bean
class="com.healthme.webapp.adapter.CommonController Adapter"/>
</mvc:interceptor>
</mvc:interceptors>
The blocker class CommonControllerAdapter realizing configuration as above inherits org.springframework.web.servlet.handler.HandlerIntercept orAdapter class, can rewrite the method preHandle of described class and postHandle to the control method of the resource access realizing the present invention and propose.In these two methods, extract the resource data that will access, the group coding then organized belonging to resource data and the group coding of login user judge the legitimacy of resource access operations.
For ease of understand the present invention propose described group coding and group mark, below in conjunction with Fig. 2 to described group coding and group mark setting and management specifically describe.
Fig. 2 illustrates the group coding of exemplary embodiment of the present and the schematic diagram of group mark.
According to exemplary embodiment of the present invention, each group under same tissue is logically set to tree topology.Any node in described tree topology is set as group, and sets group belonging to it and corresponding group coding respectively for each user of access authorization resource and each resource of granted access that needs of needing.Wherein, for each group arranges unique group mark, and the group coding of group mark and self the group mark comprising belonging to it at different levels groups is set.In group coding, the group of at different levels groups belonging to it can be identified in described tree topology and write from top group of downward order, and the group of self mark is placed on last.In described tree topology, have unique one top group, the group on other each nodes has unique direct higher level's group.In advance the group coding arranged for all users and resource can be stored in internal memory, configuration file or database.
Organizing in tree topology shown in Fig. 2, the unique group identity arranged for group is natural number, and the group mark of at different levels groups in group coding with "-" separately.Such as, the group that group is designated 1 is top group, its group coding is " 1 ", and the group coding that the group being arranged in the described tree topology second level is designated the group of 2 is " 1-2 ", and the group coding that the group being arranged in the described tree topology third level is designated the group of 5 is " 1-2-5 ".
As can be seen from the arranging of group coding that the present invention proposes, contain at different levels groups belonging to group and the group mark of himself in group coding, therefore, as long as the group coding of certain resource A comprises the group coding of certain user B, so user B has the authority of access resources A.
Suppose to be institutional framework in hospital journals management system shown in Fig. 2.By convention, doctor can only check the case of its patient oneself be responsible for, and can not check the case of other patients.As shown in Figure 2, group is designated 1 top group and represents this tissue of hospital; Group is designated the Zu Shi section office C of 2, and its group coding is " 1-2 "; Group is designated the Zu Shi section office D of 3, and its group coding is " 1-3 "; Group is designated the group coding of the group (as clinic E) of 4 for " 1-2-4 ", and the group coding that group is designated the group (as clinic F) of 5 is " 1-2-5 ".
If the doctor G of section office C attempts the case (group coding of case belonging to specifying is " 1-2-4 ") of checking the patient that the clinic E that group is designated 4 is responsible for, the group coding (i.e. " 1-2-4 ") of the group belonging to the resource (namely group coding is the case of " 1-2-4 ") that will check comprises the whole groups of marks of section office C, therefore can determine that the doctor G of section office C can check that group coding is the case of " 1-2-4 ".
On the other hand, if the doctor H of section office D attempts to check that group coding is the case of " 1-2-4 ", group coding (i.e. " 1-2-4 ") due to the affiliated group of the resource (namely group coding is the case of " 1-2-4 ") that will check does not comprise whole groups of marks of group belonging to doctor H, and group coding is the case of " 1-2-4 " therefore can to determine do not have authority to check by doctor H.
