CN101453481A - Method for implementing notification through cache - Google Patents

Abstract

The invention provides a method for realizing notice through cache. Firstly, a client sends heartbeat signals to a server every 5 minutes; the server reads memory cache information of an application server according to the ID number and type provided by the client, the application server caches data through a Dictionary, and the ID and the client terminal type only determine a message; the client terminal acquires information returned by the server; the client terminal transfers actual server interfaces of the server from high priority to low priority according to the priority of each step of operation in the information; the queue cache of the memory information provides an information updating interface to make information stored in the database updated to the memory cache; and the function for greatly providing concurrent information notice for users can provide individual information notice for each user.

Description

A kind of method that realizes notice by buffer memory

Technical field

The present invention relates to a kind ofly realize the method for notice by buffer memory, particularly a kind of is a large amount of concurrent users informing functions that give information by a large amount of message of buffer memory in the application server internal memory, and the method for personalized message informing is provided for each user.

Background technology

Wireless interconnected online, it is not an easy thing that server active push information is given client, most technical scheme or real-time are not strong, excessive to the pressure that server end causes. this programme is conceived under the prerequisite of as far as possible saving server resource, realizes that by advice method server end pushes information to client.

Summary of the invention

Main purpose of the present invention provides a kind of method that realizes notice by buffer memory.Being particularly related to a kind of is a large amount of concurrent users informing functions that give information by a large amount of message of buffer memory in the application server internal memory, and the method for personalized message informing is provided for each user.

The object of the present invention is achieved like this:

1, a kind of method by buffer memory realization notice, it is characterized in that: this method comprises following step at least:

Step 1: client is sent heartbeat signal every 5 fens clockwise servers;

Step 2: ID number of providing according to client of server and type read the message of application server memory cache, and application server comes data cached by Dictionary, the unique definite a piece of news of ID and client type;

Step 3: client obtains the message that server returns;

Step 4: client is according to the priority of each operation in the message concrete business interface of invoking server from high to low;

Step 5: the internal memory message queue buffer memory updating interface that gives information makes the message of storing in the database also can be updated in the memory cache;

2, a kind of method that realizes notice by buffer memory according to claim 1, it is characterized in that: ID number of providing according to client of server and type read the message of application server memory cache, application server comes data cached by Dictionary, the unique definite a piece of news of ID and client type the steps include:

Step 21: the latest news that reads current I D and client type from database;

Step 22: if message is arranged in the database, be cached to application server earlier after then reading out, and return to client simultaneously;

Step 23:, then directly return to client if there is not message in the database.

Description of drawings

The overall structure schematic diagram of the system that Fig. 1 relates to for embodiments of the invention

Embodiment

Referring to Fig. 1, system is according to client user's ID number (less than 19 long numeral) and client type (enumeration type constant, may be Mobile, PC, Web) obtain up-to-date messaging list, these message all are that (basic structure of these objects is operating lists to object, they divide priority, because client will be come these message of ordinal response according to the priority), if message is interior

Attribute/method explanation

Message id does not repeat, and can use guid, can oneself realize other algorithms yet

Priority can be with 0,1, and 2...... represents that numerical value is more little, and priority is high more;

Priority level is uncertain

Father's message writes down it here and complies with because the execution of some message depends on other message

The id of the father's message that relies may have a plurality of father's message

Each operation of operating list comprises interface name, interface boards this shop and the needs of server

The various parameters of importing into.

Other describe the comment that writes down some plain texts here message, may be used to point out

Text message is given the user

Deposit in the message queue and exist, so with directly obtaining message from internal memory returns to client, otherwise the information of reading database at first, if there is this information in the database, then read out the back and return to client message again behind the first buffer memory, if do not have message in buffer memory and the database then return-1 expression and do not find message.After client is obtained message, the interface of sequence call server end is according to the priority obtained business datum.Message body object basic structure is as shown in table 1.

Table 1

Key step of the present invention is as follows:

Step 1: client is sent heartbeat signal every 5 fens clockwise servers;

Step 2: ID number of providing according to client of server and type read the message of application server memory cache, and application server comes data cached by Dictionary, the unique definite a piece of news of ID and client type.

Step 3: client obtains the message that server returns

Step 4: client is according to the priority of each operation in the message concrete business interface of invoking server from high to low

Step 5: the internal memory message queue buffer memory updating interface that gives information makes the message of storing in the database also can be updated in the memory cache.

ID number of providing according to client of above-mentioned steps 2 servers and type read the message of application server memory cache, and application server comes data cached by Dictionary, the unique definite a piece of news of ID and client type.Concrete steps as follows:

Step 21: the latest news that reads current I D and client type from database;

Step 22: if message is arranged in the database, be cached to application server earlier after then reading out, and return to client simultaneously;

Step 23:, then directly return to client if there is not message in the database.

Above-mentioned technical scheme is a large amount of concurrent users informing functions that give information when implementing, for each user provides personalized message informing.

It should be noted last that above embodiment is only in order to explanation and unrestricted technical scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to the above embodiments,, those of ordinary skill in the art should be appreciated that still and can make amendment or replacement to the present invention with being equal to; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.

Claims (2)

1, a kind of method by buffer memory realization notice, it is characterized in that: this method comprises following step at least:
