Description
Technical field
The present invention relates to computer fields, it particularly relates to the information push method and device of a kind of server.
Background technique
In the system of enterprise-level, especially need to realize server background data be constantly synchronized to the monitoring of client with
And immediately in the exploitation of the cloud computing system of event message, under the framework of BS, back-end data how can be allowed efficiently immediately steady
The fixed front end page that is pushed to is always a problem, and the offline acquisition of information can especially be supported to push.It needs exist for examining
Consider two aspect the problem of, one be message source acquisition, another is the efficient instant push of message.
In the development of past server push technology, the mode using ajax short poll and long poll is most commonly seen, it
Be all by intermittently obtaining data based on original http request server, in a sense, belong to server drawing
The actively request to server transmission acquisition data of the mode taken, i.e. client, rather than server end.Short poll mode is every
It is returned immediately after secondary request, but long poll is will not to return immediately after requesting but hang up request until server end has data
Client is just returned to afterwards.
On the other hand, how to realize that the offline push of message is also one and cannot solve very well in past solution
Certainly the problem of, needs exist for settlement server and has been pushed to front end but the message that also presents not in time of front end how can
It shows again, and can realize that the information of page formula is pushed for the switching of the different pages.The prior art mostly uses greatly
Be server level other session storage either local cookie storage, and of the invention in this system design use
It is WebStorage technology.
For using ajax short poll technology, needs to request from sending to server end for client timing, realize
The effect of periodic refreshing, but due to this mode can not accurately awareness server end whether really have message need push and
A large amount of requests are wasted, and due to requesting to require the basic http connection foundation of experience one, request transmission, response every time
It returns, the process that connection disconnects, so that the load overhead at client and server end can all increase, the effect of server message push
Rate can be obviously low.And by the way of long poll, although reducing the number of invalidation request, have largely in server end
In the case that message is pushed, the load of server and client side can be still increased as short poll, is greatly likely to occur
The page it is stuck or without response the case where, reduce user experience effect.
In terms of the offline storage of information, using the other session storage of server level too dependent on server background ring
Border because it be responsive to client after server end is compiled and be stored in client browser, once backstage
Environment changes, and implementation also requires to be reconstructed.It can not accomplish the decoupling of offline environment.Obviously server level is used
Other storage can have such drawback, then will consider the storage of browser client rank, this is at present using most
Settling mode be exactly to utilize browser cookie, but there is also following two large problems for cookie mode: size of data: as
The size of storage container, cookie is limited in 4KB or so, and the information of present complicated service logic demand and large capacity is deposited
Storage can no longer meet；Network burden: cookie can be attached in each HTTP request, in HttpRequest and
All be in the header of HttpResponse it is to be transmitted, this for only for realize message offline storage be nonsensical
And increase a large amount of network burden.
In view of the above problems in the related art, currently no effective solution has been proposed.
Summary of the invention

For above-mentioned technical proposal of the invention, the present invention devises a kind of High-effective Service device based on message-oriented middleware and pushes away
Send frame.In this frame, WebSocket is used to carry out the two-way biography of server and client side's message as transport protocol
It is defeated, and carry out the management distribution of message in server end and integrated with message-oriented middleware as ActiveMQ, it supports
The request repeat of message, abnormality processing and concurrently pushes.
In addition to this, there are also being designed and developed to the push of information off-line, main includes information off-line and the page
The design of MAP mapping relations, the storage of information off-line, the acquisition of information off-line, the elimination of information off-line and pushed information feelings
The persistence of condition.In order to guarantee stability that server end is connect with client, request reconnection mechanism has been carried out again in client
Design.
In order to timely respond to the acquisition of message here the present invention using messaging service middleware ActiveMQ
(wherein, ActiveMQ is that Apache produces, most popular, the powerful open source messaging bus of ability.ActiveMQ is one complete
The JMS Provider for supporting JMS1.1 and J2EE 1.4 to standardize is realized, although JMS specification appearance has been thing for a long time,
But JMS still plays special status using centre in current J2EE).It can provide stabilization for system of the invention can
The message source leaned on, having message source, message, which just must be taken into consideration, is pushed to client, i.e. server push skill from server end later
Art.
Include four aspect contents in the present invention:
First, client sends the part of WebSocket connection request and processing from server push information.
Second, the part that server-side receives WebSocket connection and is managed to connection.
Third, message-oriented middleware dock with each connection session of server end the part of integration.
4th, the design of information off-line push function.
A. client carries out the coupling part WebSocket
Since WebSocket connection is the full-duplex communication connection between a certain html page and server, and one
A client only allows to create one and the connection of server, therefore the present invention is by the connection of the WebSocket of browser end
It is designed to a singleton, creation can be shielded in this way and repeat the problem of connecting, while the present invention connects primary WebSocket
It taps into and has gone secondary encapsulation the present invention is facilitated to be multiplexed and extend, be the API list encapsulated in the present embodiment below:
B. the part of received server-side WebSocket connection
That due to backstage language use is JAVA, devises two classes: the service of server reception WebSocket altogether here
End part is mainly made of two large divisions, receive creation connection request and carry out integrated management part and each connection example
Administrative section.Here the present invention has separately designed two classes, WebSocketServlet and WebSocketConnection,
Corresponding calling timing diagram is as shown in Figure 2:
Create part for connection request: this part is mainly responsible for receiving the WebSocket initiated from client
Connection request, belongs to the bridge Servlet at client and server end, this part mainly creates a specific session and connects
Example is connect, in order to identify the connection of different clients, needs the User ID of client connecting example with each and bind,
And stored, it is therefore desirable to a Map is created to store, it is contemplated that there may be how objective same user is for application system
The case where family end logs in, the value of this Map are also required to be the set connected, store all of user creation
WebSocket connection example.Certainly it needs exist for providing and connection example is obtained according to user and obtains all connection examples
In addition to this API is additionally provided and a series of for example sent information to all users, sends to some user and information and be given to certain
A specific client functionality page send the API of information for operation system carry out using.
For connecting instance section: having the monitor method similar as client in connection example, monitor building for connection
The vertical, reception of message, the disconnection of connection and connection error are abnormal, need to put connection example monitoring the part that connection is established
Enter into the connection Map set of request creation part, and connects to need to remove in Map when disconnecting and be correspondingly connected with example.
C. the integrated part of message-oriented middleware
It is more the information of system business rank for the information to be sent, in cloud computing operating system, can deposits
In the information that a large amount of monitoring collection and hardware state change, the present invention, which is often placed on as the producer of message, to disappear
It ceases in middleware, since these information need to broadcast to multiple client, using hair in the embodiment of the present invention
Cloth subscribing mode, here due to consider need for user connect with WebSocekt carry out bind safeguard be also required to maintenance one simultaneously
Two kinds of situations of disconnection of the relationship that a user connect with MQ, the creation and connection that are divided into connection here consider.
As shown in Figure 3 for the creation of connection: under default situations, each user can monitor the information of all themes, but
It is to there is the theme message for greatly merely desiring to monitor oneself concern there may be user to realize the customization of individual character for monitoring theme, therefore meeting
The connection example of one with the ActiveMQ of the user-association are created after creating WebSocket connection example.This connection is real
Example is not required, because they should be that a shared MQ connects for multiple WebSocket connections under a user
Connect because they for message monitoring customization be it is identical, current use is judged after having created WebSocket example
Whether family has created the MQ connection of consumption terminal, if create only need by the WebSocket be added to user with
In the Map table of WebSocket articulation set, need to obtain a new consumption terminal MQ company from MQ connection pool if it's not true
It connects, and MQ connection addition is added in the Map table that user connect with MQ, while WebSocket connection will also be added to
In the MAP table of user's-WebSocket articulation set.
For the disconnection of connection, as shown in figure 4, first having to when connecting disconnection from user's-WebSocket articulation set
Connection is removed in Map table, needs to judge the WebSocket connection of the user later, if it is the last one connection, it is believed that
All terminals under the user have published system, therefore the MQ connection service provided for the user is also required to close or recycle.
D. information off-line humping section
Generally, the information of push can be divided into the information under disparate modules, the letter of this disparate modules according to delineation of activities
Breath has the characteristics that on-demand pushes, i.e., when user enters the page of current block, can just push the information of current block, but by
In server end in advance by the acquisition of information of current block to and be pushed to client, do not need temporarily only to be presented to
User, then the present invention just needs that this information to be pushed is locally stored, because the information of storage does not need persistently
Change, and carries out temporary storage just for application system, therefore the present invention is using the storage of session-level in WebStorage
Mechanism, this place just need to design the content of two aspects: the opportunity of storage and the opportunity of push.
For storage strategy, as shown in figure 5, first can after the message push that client listens to server comes
The module I D for detecting user's current page, then detects module I D belonging to pushed information again, page is just carried out when the two is identical
The presentation of face push, if module difference will be stored this information in the form of the Map of module I D-- information to be pushed set
In sessionStorage.
For push strategy, as shown in fig. 6, can determine whether the new page when user enters a new page every time
Business module, and the information off-line for whether having the corresponding service network module in sessionStorage is detected, if any can
Information is showed, and removes that information record in corresponding information off-line set.
Based on the present invention, the timely push of the server of the system informations such as monitoring collection in cloud computing system may be implemented,
It can accomplish the real-time stabilization and efficiently of pushed information, and offline push function can be carried out for user's current operation page
Can, a series of performance issues of polling technique bring, the overall customer experience of real lifting system are used before changing.
For the general frame of the message push in cloud computing application system of the invention, as shown in fig. 7, comprises clear
Look at pair at device end (browser end i.e. in client), server end (i.e. connection server) and they and message server
Connect, performance optimization problem fully considered in specific design details, the management of encapsulation, connection pool thread pool including interface, from
The memory mechanism etc. of line information, and in particular to arrive: secondary encapsulation is carried out to primary WebSocket interface in browser end, is mentioned
The reusability and scalability of high interface.WebSocket connection is managed collectively and is distributed in server end, and by its with disappear
Breath server middleware is integrated, and the Integrated Solution of efficient stable is proposed.
According to an embodiment of the invention, additionally providing a kind of message driving means of server.
As shown in figure 8, message driving means according to an embodiment of the present invention includes:
Module 81 is established in reception, for receiving the Websocket connection request of client, is asked according to Websocket connection
It asks to establish in server end and be connect with the Websocket of client；
Sending module 82, for sending Page messages based on Websocket connection；
Wherein, the Websocket connection established at server end is combined with message-oriented middleware.
In conclusion by means of above-mentioned technical proposal of the invention, by carrying out Websocket connection in server end
Unified management and distribution, and it is combined with message-oriented middleware, it can be improved the information push efficiency of server end, mention
Rise user experience.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
