Description

A Method of Dynamically Querying Application Configuration Information

technical field

The invention relates to a method for querying configuration information of an application program, in particular to a method for dynamically querying configuration information when an application program is running.

Background technique

Under normal circumstances, the application needs to read the parameters of related items in the configuration file at runtime. For example, parameters such as PageTimeOut (page locking timeout), MaxBufferSize (buffer size), LockRetry (number of retries when locking fails), etc., set the application running environment and capture potential errors by reading these parameters The average will be greatly improved. The application program needs parameters and configuration data to meet the needs of different users and environments. A good program design method and correct parameter configuration can also improve the performance of the program. Sometimes, under the same circumstances, only one parameter can be changed, and the program execution efficiency can be greatly improved. improve. When a complex application program is running, the user usually asks to query the parameter configuration that affects the running result. It is known that the user obtains this information by opening the parameter configuration file to query, or viewing the interface that has not released resources, but this method is usually relatively inconvenient. Slow, users have to wait for a long time, and it is not intuitive enough. When there are many configurations, it will often consume a lot of system resources and eventually lead to confusion.

Contents of the invention

The technical problem to be solved by the present invention is to propose a method for dynamically querying configuration information of application programs, dynamically adjust configuration parameters through multiple windows, and switch between the main interface of the program and the configuration interface, so that users can obtain configuration information intuitively and quickly.

Therefore, in order to achieve the above-mentioned purpose, the method for dynamically querying application program configuration information provided by the present invention first gives each interface an identity (ID) mark, and then stores configuration information according to the identity mark, including related parameters of the configuration interface, opening the Interface configuration file and store interface information in the configuration file, then release the interface resources, switch the main interface of the application to the configuration interface, and read the corresponding configuration file of the configuration interface at the same time, including obtaining the configuration interface ID, according to the ID Find the configuration file and read the agreed key according to the configuration file to obtain its value, and finally restore the configuration interface according to the configuration file.

According to the method for dynamically querying the configuration information of the application program proposed by the present invention, the configuration information is directly fed back to the configuration interface, thereby achieving the effect of convenient and intuitive acquisition with a small cost. Since the XML file is used as the storage format, it is convenient to rearrange and format the configuration. The restoration of the interface of the present invention is carried out by a separate thread, which will reduce the interference to the main thread and ensure flexible and convenient configuration viewing during operation.

The foregoing purposes, features and advantages of the present invention will be better understood after coordinating the following descriptions and accompanying drawings:

Detailed ways

Application configuration information is usually saved in an external file, and programmers can update certain properties of the application without recompiling the application. The present invention is a method for real-time inquiring about partial or overall configuration of software and hardware during the running of a program. With the help of XML file access, the dynamic inquiring of configuration can be completed with very little resource overhead, which is intuitive, convenient and flexible.

The invention separates the running window from the configuration window, switches between the running window and the configuration window at running time, and reads corresponding configuration files according to different configuration interfaces to restore the interface.

First, the flow process of the present invention is illustrated by Fig. 1, which is a flow chart of the method for dynamically inquiring application program configuration information proposed by the present invention, at first giving each interface an identity mark (step 110), and storing configuration information according to the identity mark (step 120), release the interface resources (step 130), switch the application program main interface to the configuration interface, read the corresponding configuration file of the configuration interface (step 140) simultaneously, restore the configuration interface (step 150) according to the configuration file.

According to the method provided by the present invention, a unique ID is given to each configuration interface according to certain rules, and then the configuration information is stored according to the ID.

Fig. 2 is a flowchart of storing configuration information in the present invention. The invention uses a series of XML configuration files to set the basic attributes of the program execution environment. The XML file is used as the storage format to facilitate configuration rearrangement and formatting. First configure the relevant parameters of the interface (step 210), such as switching the interface or modifying some key values. Such as modifying a string, selecting a value in a list, changing the state of a button, etc. Then open the configuration file (step 220) of this interface, here is to open or create a file (if the file does not exist, then create a file) with ID (or the transformation of ID) as the file name, with Key-Value paired mode will The information to be stored in the interface is stored in this file, that is to say, a key value corresponds to a value, and the value value can be queried immediately from the key value. Save each interface state to the value (Value) of the agreed key (Key). The interface information is thus stored in the configuration file (step 230).

At this time, the interface resources are released, and only frequently used resources are cached. When the user switches to another interface, save the control state of the modified configuration interface to the XML file, and then decide whether to destroy it according to the frequency of the interface display, if so, release the resources occupied by the interface; otherwise, hide it and add it to the buffer Add it to the interface buffer in the case of You can also use other tools to further process the generated XML configuration file, such as formatting it into a web page with XML technology, transferring it to a remote computer and using it directly for interface restoration, etc.

When the program is running, the configuration items related to the configuration interface become unwritable. When switching to a certain configuration interface, the initialization function will read the corresponding configuration file according to the agreement. If the configuration file does not exist, the default value will be used. .

Fig. 3 is a flow chart of reading configuration files in the present invention. First obtain the ID of the configuration interface (step 310); then determine whether there is a cache interface, and exit the program if there is a cache interface. It is decided by the configuration interface management thread to directly fetch from the cache or create a new interface, and then search for the configuration file according to the assigned unique ID (step 320); if the configuration file does not exist, initialize it with a default value. If the configuration file exists, read the agreed Key according to the configuration file to obtain its Value (step 330). In this way, the stored configuration is re-reflected to the interface, the state of the interface controls is refreshed, and the configuration interface is restored.

For the information detected from the system, if the user does not request to refresh, the saved configuration can be used. The restoration of the interface is done by a separate thread, and the program runs by running the main interface, the configuration interface and the main thread of the program in a separate thread. This will minimize interference with the main thread.
