Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with embodiment, it is clear that described reality
Applying example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
In order to make it easy to understand, a kind of rights management mechanism of system is described first below.In order to guarantee the safety of system,
System is usually preset with safety regulation, and perhaps security strategy is based on the safety regulation or security strategy imparting all types of user is corresponding
Access authority.User is usually accessible and can only access oneself authorized system resource.
According to control, above-mentioned rights management mechanism can be divided into functional level rights management and data level permission pipe
Reason.Functional level rights management therein, using access control based roles technology (Role Based Access Control,
Abbreviation RBAC) access authority of user is managed.Fig. 1 show based role and accesses the system permission model of control
Figure.User is divided into different types of role, then revests the specific access authority of all kinds of roles.
In addition, above-mentioned rights management mechanism, which can also be divided into, obtains data permission management and submission according to control direction
Data permission management；It is therein to obtain the rights management that data permission management includes the operations such as inquiry order, inquiry customer data；
Submitting data permission management includes deleting the rights management of the operations such as order, modification customer data.
By taking information management space system as an example, system using access control based roles technology access control when,
System is that the user of different role distributes different access control rights；For example, ordinary user, which only has, adds and moves file
Permission, administrator have the permission of addition, movement, deletion.It is common to use since ordinary user does not have the permission for deleting file
Family is when using the memory space of system, if because maloperation creates extra space child node or updates attachment documents
When, extra child node or expired attachment documents can not be deleted.It is common since administrator has the permission for deleting file
The case where node or file that user needs to illustrate to be deleted to administrator, and corresponding removal request is submitted, then by managing
Member deletes corresponding node or file.
It is this by way of administrator's labor management system memory space, realize the classification pipe of system access right
Reason, ensure that the safety of system, but increase system maintenance cost simultaneously；And administrator may not be able to timely delete operation
Node or file easily lead to the waste of memory space.
Based on this, the embodiment of the present invention provides management method, device and the server of a kind of system memory space, the technology
It can be applied in all kinds of systems for being provided with access privilege control mechanism, such as Knowledge Sharing system, on-line operation system.
Firstly, a kind of flow chart of the management method of system memory space shown in Figure 2；It is deposited using this method
Recycling node should be preset with by storing up in the system of space management；The recycling node can specify for recycle bin in system or one
Storage region etc..The parameters such as the position of the corresponding storage region of recycling node and size, can be by having setting permission
User is arranged in systems, can also be arranged automatically by system.
The management method of above system memory space the following steps are included:
Step S200, inquiring in recycling node according to predetermined period whether there is node to be emptied.
The predetermined period can also be arranged automatically by having the user of setting permission to be arranged in systems by system；
According to the regulatory requirement of system, which can be set to or grow or short time span, and such as 1 hour, 24 hours, one week
Deng.Above-mentioned node to be emptied can be usually moved to recycling node by user；Should node be emptied generally comprised node identification,
Nodal information (original storage position, node settling time, node creator and the node size of such as node), node content,
Attachment etc..As an example, the node identification of node that should be to be emptied is " service manual of tester ", node content is text,
The application method of tester is described, attachment is usually the data of other non-legible formats such as screenshot, document, link.
A storage region in the usual correspondence system memory space of one node preserves in the storage region and belongs to this
The data such as text, document, the picture of node；When user establishes a node, system is that the node distributes a memory block
The position in domain, the node can move, such as will be under a certain node motion to above-mentioned recycling node；At this point, belonging to the node
Data are then moved in the corresponding storage region of recycling node from former storage region, and former storage region is released.
With the presence or absence of wait empty in node process in inquiry recycling node, one way in which can inquire the recycling section
The lower node topology of point, if including other nodes under the recycling node, can determine in recycling node in the presence of to
Empty node.Another way can also inquire the current residual memory space of recycling node, if residual memory space is less than
The difference recycled between the preset memory space of node, or the preset memory space of recycling node and residual memory space is greater than
Preset threshold can then determine in recycling node there is node to be emptied.
Step S202, if there is node to be emptied, judgement should node be emptied whether meet and preset empty condition.
This empties condition can be by having the user of related setting permission to be arranged in systems, change, can also be by being
The automatic setting of system.This empty condition can node identification, nodal information, node content, attachment based on node to be emptied etc. into
Row setting；It can specify the character for including in node identification for example, this empties condition, the storage location range of specified node, build
Vertical period, role of creator etc.；This empty the character that condition can also specify node content to include, node content it is big
Small, attachment format, size of attachment etc..
The above-mentioned condition that empties may include a condition or multiple sub- conditions；When the condition of emptying includes multiple sub- conditions,
Each subconditional logical relation can also be set, which can be "AND" "or" " non-" etc.；For example, emptying condition packet
Three sub- conditions, respectively condition 1, condition 2 and condition 3 are included, the logical relation between these three sub- conditions is "AND", i.e., to clear
Empty node needs while meeting condition 1, condition 2 and condition 3；Logical relation between these three sub- conditions is "or", i.e., to clear
Empty node need to meet in condition 1, condition 2 and condition 3 one of；Logical relation between these three sub- conditions can be with
Comprising "AND" and " non-", node such as to be emptied needs while meeting condition 1 and condition 2, and is unsatisfactory for condition 3.
Step S204, if meet it is above-mentioned empty condition, empty node to be emptied according to the preset mode that empties.
This is preset, which to empty mode, to be various ways, such as delete that all data of the node to be emptied, delete should be to
Empty the specified data (such as text, attachment) etc. of node；This empties mode and can also execute according to certain conditions, as attachment is big
Attachment is just deleted in specified size.
The embodiment of the invention provides a kind of management methods of system memory space, first, in accordance with predetermined period inquiry system
In no in preset recycling node there is node to be emptied；If recycling and there is node to be emptied in node, judgement should be to clear
Whether empty node, which meets, preset empties condition；Meet empty condition in the case where, empty this according to the preset mode that empties
Node to be emptied.In this method, system is provided with recycling node, inquires the recycling node with predetermined period timing, and based on pre-
If empty condition and empty mode and empty node to be emptied in the recycling node；The node administration mode of this automation can
To reduce the maintenance cost of system memory space, relative to administrator clear up node mode, which much sooner, efficiently,
Reduce the waste of memory space.
The embodiment of the present invention also provides the management method of another system memory space, and this method is described in above-described embodiment
It is realized on the basis of method；This method emphasis describe it is above-mentioned empty condition, empty the particular content of mode, and judge wait empty
Whether node meets the preset detailed process for emptying condition.
In the present embodiment, the condition of emptying may include at least one of following:
Condition 1: node to be emptied, which is added to the time span of recycling node, is greater than or equal to preset time span.
For example, the preset time span can be set to 1 hour, 24 hours, 10 days etc..When node to be emptied is stored in
When recycling the time in node more than or equal to the time span, the determination node to be emptied meets this and empties condition.In reality
When realization, calculated since at the time of node to be emptied is added to recycle bin, at the time of addition to recycle bin can be obtained with work as
The difference at preceding moment, the difference, that is, above-mentioned time span.One section of phase buffer can be provided for user by the way that above-mentioned condition 1 is arranged,
User can also be from recycle bin by node reverts back to be emptied to original storage region in above-mentioned time span.
Condition 2: including the first preset characters in the node identification of node to be emptied.
First preset characters can be preset, and be notified to system user, for example, first preset characters can be
" being completed ", " to be deleted ", " out of date " etc.；When user is wanted some node motion to recycling node, in the node identification
The first preset characters of upper addition, then by the node motion to recycle bin.In addition, in order to avoid deleting significant data, this is first pre-
If character can also be the character of characterization nodal community, such as the task attribute of the type attribute of node, node；Such as this is first pre-
If character can be set to " to entertain ", " news ", " knowledge "；If including one of character in node identification, that is, can determine
It include the first preset characters in node identification；Which can limit the model for the node that can be deleted by the first preset characters
It encloses, important node, sensitive nodes is avoided to be deleted.
Condition 3: the character length wait empty word content in node is less than preset first character length.
The character length and the first character length can be indicated with data volume, such as 5M, 10K；Number of words, character can also be used
Number, line number etc. indicate.In order to avoid accidentally delete be not necessarily to delete node, can notify user by node be sent to recycling node it
Before, the word content in node is first emptied, or the character length of word content is reduced to the first character length, to guide user
In deletion of node, once checked have the function of prompting the careful deletion of node of user to the content of node.
Condition 4: the data volume wait empty attachment in node is greater than or equal to preset first data volume.
First data volume can be preset, such as 10M, 1G.It, can be clear based on this if the data volume of attachment is larger
Empty condition is deleted as far as possible, in order to avoid it is somebody's turn to do a large amount of memory spaces that node to be emptied occupies recycling space for a long time.
The condition of emptying may include one or more of aforementioned four condition, if comprising multiple, between each condition
Logical relation can preset.For example, it includes above-mentioned condition 1 and condition 4 that this, which empties condition, it is between the condition 1 and condition 4
The relationship of "or", that is, meet in condition 1 and condition 4 one of node to be emptied can be emptied.As an example, emptying condition and being
Condition 1 or condition 4, the predetermined time period in condition 1 therein are set as 5 days, and the first data volume in condition 4 is set as
10M；If the time that node to be emptied is stored in recycling node is greater than or equal to 5 days, the node to be emptied can be determined
Eligible 1；If being greater than or equal to 10M wait empty attachment data amount in node, it can determine that the node to be emptied meets
Preset to empty condition, being somebody's turn to do node to be emptied can directly empty, without meeting the predetermined time period in condition 1, thus real
Now quickly delete the purpose of big data quantity node.
Based on it is above-mentioned enumerate empty condition, multiple groups can also be divided and empty conditional combination, comprising above-mentioned in each combination
Empty one or more of condition；Each condition for including that combines is typically different, to realize specific space management demand.Base
In this, the management method of the system memory space in the present embodiment includes the following steps, as shown in Figure 3:
Step S300, inquiring in recycling node according to predetermined period whether there is node to be emptied；If so, executing step
S302；If not, executing step S300.
Step S302 obtains the user group mark for sending node to be emptied to the user for recycling node, and wait empty section
The node group identification of point.
Under normal conditions, user is when operating node, such as establishes node, updates node content, mobile node
Operation；The information such as the user group mark of the user and corresponding operation can be recorded in nodal information.User group mark
It can be understood as the character types mark of user, department mark of user etc., for example, the user group is identified as common use
Family, administrator, cloud storage department user, cloud computing department user etc..
The node group identification of above-mentioned node to be emptied is generally held in the nodal information or node identification of the node；The section
Point group mark can be understood as the type identification of node, department mark etc.；For example, ordinary node, special joint, cloud storage
Node, cloud computing node etc..
Step S304, judges whether user group mark and node group identification match；If matched, step is executed
S306；If mismatched, step S308 is executed.
In actual implementation, the matching relationship of user group mark and node group identification can be pre-established and be saved；Pass through
Inquiring the matching relationship can be determined that out whether user group mark and node group identification match.In another way, mutual
The user group mark and node group identification matched can be set to identical or corresponding character, if user group mark and node group mark
It is sensible same or corresponding, then it can determine that user group mark and node group identification match.For example, belonging to the user of cloud storage department
User group be identified as cloud storage, the node group identification for the node for belonging to cloud storage field is also cloud storage；If to be judged
User group mark is identical with node group identification, then the two matches.
Step S306, judges whether node to be emptied meets preset first and empty conditional combination；If met, step is executed
Rapid S310；If do not met, step S300 is executed.
In order to limit and supervisory user is to the opereating specification of node, the present embodiment be in advance based on it is above-mentioned enumerate empty condition
It is combined into two groups and empties conditional combination, respectively first, which empties conditional combination and second, empties conditional combination；This first empties item
Part combination and second empties conditional combination and includes and above-mentioned empties at least one of condition.User group mark based on user
Matching relationship between the node group identification of node to be emptied, using emptying conditional combination judges that node to be emptied is accordingly
It is no to be emptied.
In general, when user group mark matches with node group identification, it can be understood as user is to routine operation
Node in space or routine operation field is moved；For example, user group is identified as ordinary user, then corresponding routine operation
The node that space includes is ordinary node；User group is identified as cloud computing, then corresponding routine operation field is cloud storage.At this time
First empties to can wrap in conditional combination and empties condition containing more loose, is such as only added comprising node to be emptied to recycling and saves
The time span of point is greater than or equal to 1 day.
Step S308, judges whether node to be emptied meets preset second and empty conditional combination；If met, step is executed
Rapid S310；If do not met, step S300 is executed.
When user group mark with node group identification it is unmatched when, it can be understood as user to across operating space or across
The node of field operation is moved；For example, user group is identified as ordinary user, then the node for including across operating space is special
Node；User group is identified as cloud computing, then is cloud storage across field operation.Above-mentioned at this time second empties in conditional combination and can wrap
Containing the more rigorous condition that empties, such as it is greater than or equal to 1 day comprising the time span that node to be emptied is added to recycling node,
It also, include the first preset characters " out of date " in the node identification of node to be emptied, also, wait empty in node in text
The character length of appearance is less than preset first character length " 50K ".Which identifies with node group identification according to user group
Conditional combination is emptied using different with relationship, user's node mobile across space is deleted with caution, user is avoided arbitrarily to delete footpath between fields
Raw field or the not node of permission.
Step S310 empties node to be emptied according to the preset mode that empties.
As described in above-described embodiment, this empties mode can be there are many form；As an example, one way in which is to delete
The node identification of node to be emptied in front end page, but retain the related data of the node to be emptied in background data base.Due to
The node identification of node to be emptied is deleted in front end page, it can be understood as is deleted the access interface of the node, thus is used
Family can not access the node again, and the content of the node stops updating.
Another way is to delete wait empty the data saved in node in database, but retain in front end page wait empty
The node identification of node.Original node content is deleted in node after emptying, but due to remaining with the section in front end page
The node identification of point, the node still can be accessed by the user, the new node content of editing and updating.In the third mode, delete
The node identification of node to be emptied in front end page, while deleting in database wait empty the data saved in node.
The above-mentioned different mode that empties can be associated with condition is emptied, for example, when meeting conditional combination A, using only deleting
Except the node identification of node to be emptied in front end page empties mode, when meeting conditional combination B, using only deleting in database
The case where wait empty the data saved in node mode.Conditional combination A and conditional combination B includes above-mentioned empties in condition
At least one.
It needs to apply to administrator relative to user's deletion child node or attachment documents and delete operation is executed by administrator
Mode, above-described embodiment automation inquire simultaneously delete recycling node in node, can substantially save human time's cost, and
When release system deposit space.Time using aforesaid way management system space is longer, and human time's cost of saving is got over
Height, releasable server storage are also bigger.
Further, in aforesaid way in the case that user group mark and node group identification match or mismatch two kinds,
Using emptying condition judges whether node to be emptied can be emptied accordingly, which can be arranged more flexiblely to be emptied
Condition meets different user, establishes without the system space under application scenarios.In addition, can be set a variety of when emptying node
Mode is emptied, to further increase the flexibility and reliability of system memory space management.
The embodiment of the present invention also provides the management method of another system memory space, and this method is described in above-described embodiment
