Topic；And using change lock mark, before Template Information synchronously completes, inquiry data source switching at runtime to database ensures
Inquiry gained Template Information is consistent, accurate；Monitor the internal memory service condition of current server, if current memory using more,
Then intelligently by data source from internal memory to switch data storehouse, the availability of distributed type assemblies is improved.
Fig. 1 is the schematic diagram of the key step of the method for Template Information management according to embodiments of the present invention.
As shown in figure 1, the method for the Template Information management of the embodiment of the present invention includes：
Step S11：Template in database is initialised in internal memory by each server in distributed type assemblies, for template
Inquiry and/or change；
Step S12：When there is template change request, server is according to the template change request got to the phase in internal memory
Answer template to be changed, and the template after change is preserved to database；
Step S13：Then the template after the change is sent to its in distributed type assemblies using cluster communication component

In addition, the method for the Template Information management of the embodiment of the present invention also includes：Server becomes according to the template got
More ask after being changed to the corresponding template in internal memory, change lock mark, the change lock mark bag are added into caching
Include title, timestamp and the server number for needing synchronization of the template changed.
It is wherein, concurrent that change lock mark is added into caching if the template in server memory occurs concurrently to change,
But caching holding time stamp shows the change lock mark of time the latest.
In addition, change after template in comprising template change timestamp.When other servers in distributed type assemblies receive
After template after to the change, the change lock mark in caching is obtained first, then by the template of the template after the change
The timestamp of change timestamp and change lock mark is contrasted, no if unanimously, being changed to the corresponding template in internal memory
Do not process then.Other each servers in distributed type assemblies, the template after according to the change is to the phase in internal memory
Answer after template changed, synchronous server number will be needed to subtract one, when needing synchronous server number to be kept to zero, namely
After last server completes synchronization, synchronous server number will needed to subtract for the moment, removing change lock mark in the lump.

When internal memory service condition exceedes predetermined threshold value, then template is obtained from database according to template query demand, when internal memory uses feelings
When condition is no more than predetermined threshold value, then template is obtained from internal memory according to template query demand.
Fig. 2 be Template Information management according to embodiments of the present invention method in by the template synchronous after change to distribution
The schematic diagram of the main flow of other servers in cluster.
Below by taking invoice template as an example, detailed process introduction is carried out to the method for Template Information management with reference to Fig. 1 and Fig. 2.
Certainly, the present invention can also solve the stationary problem of other information under distributed deployment, be not limited only to invoice template.
First, in the embodiment of the present invention, during in order to ensure that the template in a server memory changes, promptly and accurately
Other servers sent information under distributed type assemblies, it is necessary to which every server is connected to by cluster communication component
Same group's name：Such as can be INVOICE_TEMPLATE_JGROUPS.Now, under this distributed type assemblies, every
Server can serve as client, send information to other with the server under groups, to ensure between each server
Mutual communication, without safeguarding the extra machine as service end.
The JGroups that the cluster communication component of the embodiment of the present invention uses, JGroups are that a pure java to increase income writes
Reliable cluster communication instrument.It is a reliable multicast communication tool set.Its mode of operation, which is based on ip multicast, (to be needed
Bright, here it is not always necessary that can also be realized using IP Multicast, JGroups using TCP), but can be can
By being extended on property and group member management.A kind of flexible design in its structure, there is provided association of flexibly compatible various protocols
Stack is discussed, there is different reliability requirements for each product.This protocol stack can allow user to define reliability index and property
Can index.JGroups can be used for creating a group, and the member in this group can give other members to send message.
In addition, in order to reduce the pressure to database access, each server is by the mould in database in distributed type assemblies
Plate information aggregate, such as can be each region in Template_List, the invoice template information initializing of each printer model
Into internal memory, for inquiring about and changing.And after changing every time, invoice template in database all can be correspondingly changed, ensure
Database is arrived in newest invoice template information landing.
For example, each Template Information in Template_List is：TEMP_A_20150606121212、TEMP_
B_20150606121212 etc., wherein, TEMP_A_20150606121212 be a-quadrant Template Information, TEMP_B_
20150606121212 be the Template Information of B area.The layout of each Template Information including the region invoice, issue content,
Invoice number, impress.
During invoice issuing system operation, if one of template TEMP_A_20150606121212 information
Change (such as can be one or more) in increasing newly, change and deleting is needed, is to occur in the cluster due to changing operation
A certain server, it is therefore desirable in the internal memory for other servers that the invoice template after change is synchronized under cluster, ensure
The template content obtained during the Template Information of external inquiry a-quadrant is completely the same.
As shown in Fig. 2 S_1 servers receive the change to a-quadrant invoice template TEMP_A_20150606121212 first
More operation requests, after change operation is carried out to a-quadrant invoice template, change Template Information deposit database (is protected first
Card database can use), then deposit becomes in caching (such as one kind in can be, but not limited to be Redis, Memcache etc.)
More lock mark (such as can be REDIS_LOCK_TEMP_A_20160606121212_3), each server can be read by caching
Change lock mark is taken, change is locked in mark is comprising content：The title of the template changed, change operation time of origin stamp with
And need synchronous server number.Change lock tagging mechanism in caching can ensure with the value in a caching, while can only have
One successfully modified, ensures that each server needs synchronous server number to subtract change lock mark after performing simultaneously operating
One, and treat that Servers-all synchronously after the completion of execution, removes change lock mark.
The invoice template (timestamp for including template change in Template Information) of amended a-quadrant passes through cluster communication group
The sendMessage methods of part, send to other servers under group INVOICE_TEMPLATE_JGROUPS：S_2、S_3
Deng.
Other servers under group INVOICE_TEMPLATE_JGROUPS：S_2, S_3 etc., pass through cluster communication component
Receive methods receive the Template Information of the amended a-quadrant sended over.By taking S_2 server syncs as an example, S_2
Server obtains the change lock mark of correlation from caching first, and the template lock of a-quadrant is labeled as REDIS_LOCK_TEMP_A_
20160606121212_3, and work as the timestamp authenticated in change lock mark and the amended template being currently received
When the timestamp of template change is consistent, then override with the Template Information of the amended a-quadrant received in current server
A-quadrant Template Information in depositing.So far the template synchronous renewal of current S_2 servers is completed, and will be needed in change lock mark same
The number of the server of step subtracts one：REDIS_LOCK_TEMP_A_20160606121212_2.To the last a server is same
Step is completed, and removes change lock mark.
In the embodiment of the present invention, if situation about concurrently changing occurs for the invoice template of a-quadrant, it can only be stored in caching
The change lock mark of the last time change of this template：Such as REDIS_LOCK_TEMP_A_20160606121212_3, REDIS_
LOCK_TEMP_A_20160606121313_3, concurrently change twice, then the lock mark of a storage time stamp the latest：REDIS_
LOCK_TEMP_A_20160606121313_3.If S_2 servers first receive the change of TEMP_A_20160606121212 templates
More information, and found when inquiring about the change of invoice template of a-quadrant and locking mark, the template change timestamp received, which is less than, to be become
Timestamp in more lock mark, then do not perform template synchronous, neglect this change, wait newest change template；If S_2
Server first receives TEMP_A_20160606121313 template modification informations, and according to the invoice template of the a-quadrant inquired
Change lock mark, it is found that both timestamps are consistent, then update internal memory in a-quadrant Template Information, and will change lock mark
In the number of the synchronous server of needs subtract one：REDIS_LOCK_TEMP_A_20160606121313_2.To the last one
Platform server is performed and synchronously completed, and removes this lock mark.
When the request for the invoice template for having external inquiry a-quadrant, server first obtains the invoice mould of the a-quadrant in caching
The change lock mark of plate, the change if there is the invoice template of a-quadrant lock mark, illustrate now may to carry out template same
Step renewal, then degrading data source, that is, inquire about database, ensures the Template Information that inquires to be newest, and Servers-all
Query Result is consistent；Mark is locked if there is no the change of the invoice template of a-quadrant, then shows that the invoice template of a-quadrant has no
Change operation, audit memory has been newest invoice template.This is to utilize change lock mark, switching at runtime data
Source.
In addition, in the embodiment of the present invention, in order to improve the availability of distributed Template Service cluster, current point of poll monitoring
The internal memory service condition of the server of cloth cluster, such as utilization rate, if monitoring memory usage reaches predetermined threshold value, such as
K is set to, then intelligence switching inquiry data source to database；If memory usage is reduced to below K, data source switches back into interior
Deposit.
The method of Template Information management according to embodiments of the present invention can be seen that by the way that the template in database is initial
Change into internal memory, so as to provide a large amount of concurrent inquiry services；Communicated by using cluster communication component, so as to
Synchronous server is needed so that the information that template changes accurately is sent into other in time, efficiently completes simultaneously operating；Pass through
Template after change is preserved to database, thereby may be ensured that the process of template synchronous, the data in database can use；Pass through
After by the template change in internal memory, change lock mark is added into caching, so as on the one hand ensure in change template
Synchronizing process in, the data source inquired about during external inquiry is the valid data in database, on the other hand can ensure cluster
In other servers accurately obtain the information of template synchronous, to complete simultaneously operating；In addition, by a caching holding time
The change lock mark of stamp the latest, thereby may be ensured that when the situation that template concurrently changes be present, the synchronous letter of distributed type assemblies
Cease for same information, avoid data syn-chronization from going wrong；By monitoring the occupancy situation of internal memory, so as to the switching mould of intelligence
The data source of plate inquiry, ensure that distributed type assemblies do not collapse because server memory service condition exceedes threshold value.
