Description
Technical field
The present invention relates to the log information export technique, relating in particular to can be to log information the log information output system and the output intent controlled of output.
Background technology
In the overall process of application development, no matter write what good test cases of design, even minimum application program also can be after being deployed to production environment under cover one or more mistakes.Though exploitation and quality assessment (Quality Assessment that test drives, abbreviation QA) means can improve code quality and strengthen the confidence of application programs, but when certain system or function failure, developer and system manager need understand the Debugging message such as relevant execution context of system, suitable information has been arranged, could also deal with problems fast by the essential of problem identificatioin, thereby save time and money.
Under the Java environment, although emerged the means of many debugging utilities, but directly Debugging message is outputed to file (perhaps other places) and remain very important means, especially in debugging during distributed application program, or even unique utilizable method.In application program, add log record generally speaking based on three purposes: monitor the situation of change of variable in the code, periodically record in the file and carry out statistical study work for other application; Track when following the tracks of the code operation is as the foundation of auditing in the future; The effect of taking on the debugger in the Integrated Development Environment is to the Debugging message of file or control desk print code.
Information is outputed to screen, the System.out.println (systems approach that Java provides, output information is to screen) that the simplest method just is to use JDK (Java Developer ' s Kitjava development kit) to provide.But, there are some problems like this: the output underaction of information, and loaded down with trivial details.For example, the content of output is the filename of execution place, and line number, seems very original at the current time etc.If change the content and the form of output, need to recompilate source program.More seriously, if a lot of such output statements are arranged in the program, can seriously influence the performance of program.
In order to solve top problem, people have developed the software package of some special record Debugging message, for example, and Log4j (Log4j=Log for java).Log4j can be used for the output of Debugging message by Apache (software organization's name) organization development.Existing Log4j mainly is made of three important assemblies: the priority of log information, the output destination of log information, the output format of log information.The priority of log information is used for specifying the significance level of this log information, can be defined by the user, in the typical case uses, priority can be set at from high to low four kinds of ERROR (mistake), WARN (warning), INFO (information), DEBUG (Debugging message); It still is in the file that the output destination of log information has specified daily record will print to control desk; The output format of log information has then been controlled the format and content of log information.As shown in Figure 1,, during print log information, obtain log record device object for a kind of daily record follower structural drawing of the prior art, and output information; The daily record follower is done as a whole, each module all is directly to call the daily record follower debugging log is printed, and there are the following problems for this:
(1) can't control the Debugging message switch respectively at different modules.
Can't discriminating module, also can't specify the log information of certain module whether to need to print.In large-scale application program, can print a large amount of log informations, if the daily record of all modules is all exported, then influence performance, cause the client response speed slow.
(2) can't change the Debugging message switch in the runtime.
Can't when program run, change daily record and whether need the switch setting of printing.If open daily record Debugging message switch, then reduce client performance, if closing journal Debugging message switch, then can't the very first time obtain log information, when going wrong,, then need to close client-side program if open the Debugging message switch, revise runtime parameter or configuration file, just can come into force after restarting client-side program.After restarting client-side program, can't reduce at that time running environment fully, knotty problem all can't be reappeared usually, after restarting client, problem usually can not reappeared again, thereby can't the very first time obtain log information, influences orientation problem, prolong the time of developer's orientation problem, improved cost.
Summary of the invention
The objective of the invention is to control respectively at different modules the problem of Debugging message switch at existing in prior technology, a kind of output system and output intent of application log information are provided, control the output of the log information of each module by the mode of dynamic chek file.

Each application module is at first registered at controller, and by registration, each module obtains the unique object at the controller of each module, and promptly each application module has a controller object, and the controller object between each module has nothing in common with each other.By controller object, distinguish each application module.When each application module carried out log information output by calling controller, controller was checked file destination, and according to the wherein daily record output control information of record, whether decision exports the log information of this module.
File destination has write down the daily record output control information of each application module, and for example, whether the log information that writes down each module needs output, when being recorded as " A module=OK ", export the log information of this A module, when being recorded as " B module=No ", do not export the log information of B module; File destination also can only write down the log-on message of each application module that needs output journal information, and when each application module called controller object, controller object was checked the information that whether has this module in the file destination earlier, if exist, then output if do not exist, is not then exported.The program test personnel can be according to the content of test needs setting and modify target file.
As shown in Figure 3, the output intent process flow diagram for log information of the present invention comprises the steps:
Step 1, application modules are registered, and obtain unique controller object of each module;
The output control information can be by checking that file destination obtains, and controller object calls the file checking device and checks file destination after being called, and according to the daily record output control information of writing down in the file destination, exports the log information of each module.
Because the time that the inspection file destination needs is long, therefore, many at application module, and when file destination is long, if each controller object is all checked file destination after being called, can need the long time so, the real-time that information is exported has certain influence.Therefore, in a specific embodiment of log information output system, added the output switch, the state of output switch is determined according to file destination.Can be each application module one output switch all is set, the file checking device is checked file destination, and adjusts the state of the output switch of each module according to the content of file destination.For example, the file destination record needs the log-on message of each module of output journal information, and for each module that exists in the file destination, module log-on message and file destination mate, and open the output switch of these modules; For non-existent each module in the file destination, module log-on message and file destination do not match, and close the output switch of these modules.When controller object was called, the state of the output switch by checking corresponding module determined whether to export the log information of this module.Compare with checking file destination, check that exporting the used time of on off state has shortened greatly, therefore can guarantee good real-time performance.
In log information output system one specific embodiment of the present invention, further added timer, as shown in Figure 4, be the present embodiment structural representation.Every through the predetermined time, this timer 16 will send temporal information, file checking device 12 whenever receives temporal information, just file destination is checked, thereby can realize quantitative check, and can in time upgrade the state of the output switch 15 of each module according to file destination to file destination.
When working procedure, can close the output switch of each module by the content that file destination is set, do not export the log information of each module, improve client performance; When program goes wrong, the content of artificial or automatic modify target file, file checking device quantitative check file destination, in time according to amended file destination dynamic opening output switch, obtain locating information, can shorten the time of developer's orientation problem like this, reduced cost.
As shown in Figure 5, for application log information output method one specific embodiment process flow diagram of the present invention, comprise
In the process of application program operation, can or close the output switch by the modify target file dynamic opening, thereby the developer can control the output of log information easily as required.
Application modules of the present invention is distinguished, and whether daily record is set needs to print, and very many and log information unessential module is closed with log information, thereby improves client performance; Pass through the dynamic chek file destination in the runtime, control the output of each module log information, when application program goes wrong, needn't close client-side program, by on-the-fly modifying the daily record output control information in the file destination, obtain locating information fast, shorten the time of developer's orientation problem, reduce cost; Regulate the output switch according to file destination, and then, read the time of judging control information in the time of can significantly reducing output journal information, have good real-time performance according to the output of the State Control log information of output switch.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field should be appreciated that still and can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
