Specifically, the executive agent of the present embodiment can be terminal, and terminal for example can be computer.
User in development and application program, it is necessary to test application program, to determine that the source code of application program is
It is no problematic.Each program statement in source code can be defeated by increasing corresponding daily record after the program statement in source code
Go out sentence, export a daily record.Daily record includes the parameter in corresponding program sentence running, and user can be by wrapping in daily record
The parameter included, judges whether the program statement is properly executed, to judge whether the source code of application program is problematic.
It will be appreciated by those skilled in the art that although after each program statement can be by the program statement in source code
Increase corresponding daily record output statement, export a daily record, but be not that each program statement is required to according to actual conditions
Output journal, so, corresponding daily record output statement is only just provided with after the program statement of output journal in need, therefore, after
The program statement that face is provided with daily record output statement is the program statement of daily record to be output.
It will be understood by those skilled in the art that daily record output statement can be lines of code.
It is not in non-exploitation if the current running environment of application program is test environment (i.e. the environment of debugging utility)
The terminal operating of the user of personnel, then user is by will control the variable assignments in daily record output condition sentence to be in source code
Ture so that the program statement of daily record to be output can export its corresponding daily record by daily record output statement.Control daily record
The assignment of variable in output condition sentence, have decided on whether the daily record of program statement of the output with daily record output statement.
Therefore, the process for judging application program current operating environment is specially：In application program in the process of running, terminal
The current assignment of the variable controlled in source code in daily record output condition sentence is obtained, if being currently entered as the first assignment, really
It is test environment to determine current operating environment, if being currently entered as the second assignment, it is determined that current environment is non-testing environments.First
Assignment is used to indicate that current environment is test environment, and the second assignment is used to indicate to determine that current operating environment is non-testing environments.
After the current operating environment that application program is determined is test environment, the program word of daily record to be output can be obtained
The daily record of sentence.
Illustrated below for the log-output method of the program statement of a daily record to be output.
For step S101, at least one parameter in the program statement of daily record to be output is obtained.
Specifically, the parameter in the program statement of the daily record to be output of acquisition needs to meet following condition：It can reflect
Whether the program statement of the daily record to be output is correctly performed.In the program statement of the acquisition daily record to be output of acquisition at least
One parameter is stored into the internal memory of terminal.
Wherein, at least one ginseng in the program statement of daily record to be output can be obtained by the form of self-defined static variable
Number, that is, the self-defined language of static variable for the mark that at least one parameter can be included by performing application source code
Sentence, obtains each parameter.Such as：Code corresponding with least one parameter in the program statement of acquisition daily record to be output can be such as
Lower form：
Private static void k (String...args), such as when the ginseng in the program statement of daily record to be output
Several when being identified as a, b, then the code can be：Private static void k (a, b).
Wherein, the code is the wherein line code in daily record output statement.Using custom parameter in the present embodiment
Several form (i.e. by self-defined static variable sentence), it is allowed to obtain the parameter of any number.
For step S102, the program word of daily record to be output is obtained in the predeterminated position of method stack corresponding with application program
The line number of the title of Java files and the program statement of daily record to be output in the Java files where sentence.
Specifically, predeterminated position can prestore in the terminal, the Java texts where the program statement of the daily record to be output of acquisition
The line number of the title of part and the program statement of daily record to be output in the Java files is also stored in the internal memory of terminal.
Wherein, method stack is the structure of a stack, for preserving the recalls information of method when application program performs, including is adjusted
With the method name of method, Java filenames where the program statement of this method and the program statement are called in the Java files
In the information such as line number.
For example in the running of application program, when running to the program statement of the daily record to be output, this is to be output
The program statement of daily record is performed, and needs to call certain execution method during the program statement for performing the daily record to be output, then the execution
The recalls information of method can be stored in the predeterminated position in method stack corresponding with the application program, be preserved in the predeterminated position
There are the Java filenames where the method name of the execution method, the program statement of the daily record to be output and the journey of the daily record to be output
Line number of the sequence sentence in the Java files.
The recalls information of the execution method of the program statement of all daily records to be output is all stored in the application in source code
Corresponding to program at the same position of method stack.So journey for any daily record to be output in the source code of the application program
Sequence sentence is sayed：Can be in the title of Java file and the program of to be output daily record of the method stack identical position acquisition where it
Line number of the sentence in the Java files.
Such as where the program statement of the predeterminated position acquisition daily record to be output of method stack corresponding with application program
Code corresponding to the line number of the title of Java files and the program statement of daily record to be output in the Java files can be following
Form：
Stack Trace Element this Method Stack=Thread.current Thread () .get
Stack Trace()[5]；
In this way, above-mentioned Java filenames and line number can be obtained by StackTraceElement, wherein, numeral 5 is used
In instruction Java filenames and line number are obtained from the 5th opening position apart from stack top.
In addition, the program statement except daily record to be output can be obtained in the predeterminated position of method stack corresponding with application program

Target information.
Specifically, the step is that each parameter in the program statement of the daily record to be output to acquisition is spliced, and is obtained
The process of target information comprising each parameter.
Wherein, each parameter in the program statement of the daily record to be output of acquisition, obtain the target comprising each parameter and believe
Breath, is specifically included：Each parameter of object splicing is built by creating a character string, obtains including the target information of each parameter.
Because at least one parameter in the program statement of daily record to be output by self-defined static variable to be obtained in advance,
Therefore, a character string structure object need to be only created in the present embodiment and splices each parameter, the consumption of internal memory and performance to terminal
It is smaller, and the form of spliced each parameter is consistent, such as parameter a=1, parameter b=1, parameter c=2, can be a after splicing
=1, b=1, c=2 or a=1 | b=1 | c=2, and the form of target information can be a=1, b=1, c=2 or a=1 | b
=1 | c=2.
In the present embodiment obtain target information method be not in obtained in advance due to not in the prior art it is to be output
The parameter of the program statement of daily record, can only using+by the way of carry out splicing parameter (using+by the way of carry out splicing and need to create
Multiple character strings build objects) caused by the internal memory and all very big performance consumption of terminal the problem of.
