When requesting performance objective business by PRC, the service identification in the first data acquisition request can be added to and the target industry
It is engaged in relevant PRC request, so that target device can collect the business datum of target service by broker program.
In one possible implementation, this step 405 can by process shown in following step 405A-405B come
It realizes.
Step 405A, web page address and industry of the target device based on the target service in first data acquisition request
Business mark generates broker program, which executes the target service for the web page address based on target service, and should
Business datum in target service implementation procedure is sent to data center.
The target device can web page address and business mark based on the target service in first data acquisition request
Know, the bytecode of the method for original RPC request is realized dynamically modifying target device in performance objective business, and then generates generation
Manage program.Wherein, the method for realizing original RPC request is target device before performance objective business, is initiated by RPC frame
The method of RPC request.
It in one possible implementation, is that a kind of broker program provided in an embodiment of the present invention is raw referring to Fig. 5, Fig. 5
At the flow chart of method, this method process may include following step 501-504.
The web page address of step 501, target device based on the target service in the data acquisition request, determines the first generation
Code, the first code are to realize the method code of original RPC request.
Target device can be asked in performance objective business by other target devices of RPC request call to complete RPC
Indicated task is sought, when calling the method for the service of dependence, the RPC request on target device can be sent out by RPC frame
It rising, wherein the method for service refers to the call method in service provided by RPC frame, then, target device can be according to this
The web page address of target service in data acquisition request is asked come RPC when determining that target device executes the target service before
It asks, and then is requested by the RPC, first code can be determined in RPC frame.
Step 502, the target device are based on the first code and the parameter identification, generate first object bytecode, should
First object bytecode executes the target service for the web page address based on target service, and by the target service implementation procedure
In business datum be sent to data center.
For problem of implementation investigation, target device needs to execute a target service according to broker program, and then can receive
Collect the business datum of the target service, and business datum is uploaded to data center, in order to enable broker program can collect
And upload business datum, then it can be realized by modifying the bytecode of first code.
In one possible implementation, this step 502A can be realized by process shown in following step 21-24.
Step 21, the target device are based on the first code, generate the first bytecode.
The target device can use Java bytecode manipulation frame-bytecode (assembly-bytecode, ASM-
The first code is generated the first bytecode, wherein the first bytecode is the byte generated based on ASM by Bytecode) plug-in unit
Code, that is to say, ASM bytecode, and ASM-Bytecode plug-in unit is Eclipse (open source code and expansible based on Java opens
Send out platform) plug-in unit.Specifically, ASM-Bytecode plug-in unit is installed, user can open in Eclipse on the target device
First code, and " ASM " button in the Bytecode view upper right corner is clicked, the first bytecode is generated to trigger ASM.
Java bytecode manipulation frame (ASM) refers to ObjectWeb ASM, i.e. the Java bytecode processing block of lightweight
Frame can also can be filled in class by JAVA virtual machine with counterfoil (stub) class of dynamic generation binary format or other proxy class
Before entering memory, dynamic modifies class.
Step 22, when detecting that first data acquisition request carries parameter identification, the target device according to this
Method of calling in one code increases object code in the first code, obtains second code, and the object code is for being based on
The web page address of target service executes the target service, and the business datum in the target service implementation procedure is sent to data
Center.
Method of calling in first code may include any method of calling in synchronization call and asynchronous call, and first
Method of calling in code is different, and the process which adds object code in first code is different.The object code
It can be the code that technical staff writes in advance, it, can be directly in first code so that target device is when generating broker program
Middle increase object code.
In one possible implementation, this step 22 can be realized by process shown in step 2201-2204.
Step 2201, when the method for calling in the first code be synchronization call when, the target device is in the first code
Middle increase object code, obtains second code.
When the method for calling in first code is synchronization call, if after RPC request issues, target device, which needs to wait, to be returned
It returns as a result, target device could issue RPC request, although target device base after target device gets and returns the result
It may be implemented to directly acquire returning the result for RPC request in first code, still, can not really obtain the input parameter of RPC request
And method name, also just can not by required parameter that RPC is requested, return the result and method name reports to data center.
So can continue directly to increase object code in first code when the method for calling in first code is synchronization call,
To realize that the web page address based on target service executes the target service, and by the business datum in the target service implementation procedure
It is sent to data center, specifically, in performance objective business procedure, the available each RPC of the target device requests defeated
Enter parameter, return the result and method name, and is uploaded to data center.
Target device can directly increase object code, and then obtain the second generation according to preset rules in first code
Code, for the preset rules for increasing object code in first code, the embodiment of the present invention does not do specific limit to the preset rules
It is fixed.
Step 2202, when the method for calling in the first code be asynchronous call when, the target device define one readjustment
Class obtains the first readjustment class to realize asynchronous method callback interface, the call back function and processing that overwrite request executes when completing
The function of mistake, to realize that the web page address based on target service executes the target service, and by the target service implementation procedure
In business datum be sent to data center.
When the method for calling in first code is asynchronous call, if target device withouts waiting for after RPC request issues
It returns the result, next RPC request can be carried out, so target device is issuing RPC request in the case where asynchronous call
Afterwards, RPC request will not be immediately obtained to return the result, in order to realize the function of broker program, which can determine again
Adopted asynchronous method adjusts back (AsynchronousMethod Callback) interface, that is to say process shown in this step 2202.
When due to the first readjustment class for realizing asynchronous call, the target service is executed, and the target service was executed
Business datum in journey is sent to the function of data center, therefore, when redefining asynchronous method callback interface, it is also necessary to weight
It writes the method (onComplete method) executed when the RPC request in asynchronous method callback interface is completed and uses when the error occurs
Method (onError method), to realize above-mentioned function.Wherein, onComplete method is used to handle the return knot of RPC request
Fruit, onError method are used to handle the exception called and occurred in service process.
Step 2203, the target device increase object code in the first code, obtain second code.
Original readjustment class is replaced with the first readjustment class by step 2204, the target device.
Readjustment class originally is the readjustment class in first code.The target device can delete original in first code return
Tone category, and increase the first readjustment class in first code, to realize this step 2204.
It should be noted that the target device increases object code in first code when step 2201 is synchronization call
Process.When step 2202-2204 is asynchronous call, which increases the process of object code in first code.
Step 23, the target device are based on the second code, generate the second bytecode.
The target device can use ASM-Bytecode plug-in unit, which is generated the first bytecode, wherein the
Two bytecodes are ASM bytecode.
Step 24, the target device add the second target byte code in first bytecode, obtain first object byte
Code, the second target byte code are bytecode different from first bytecode in second bytecode.
Since the second target byte code is bytecode different from first bytecode in second bytecode, it is possible to understand that
, performance objective business may be implemented in the second target byte code, and the business datum of target service is sent to data center,
It include the function of the second target byte code in the function that first object bytecode is realized in turn.
Step 503, the target device are based on first object class, realize dynamic pitching pile, and the first object class is for realizing repairing
Change bytecode.
The first object class is to access the subclass of (ClassVisitor) class, and first object class is used for into compiled class
First bytecode adds the second target byte code, obtains first object bytecode, to realize the modification to the first bytecode.Its
In, ClassVisitor class is class more important in ASM frame, is one abstract for accessing all elements of java class
Class, subclass realize the read-write that can be completed after its method to compiled class.ClassVisitor is Java bytecode engine library
(ASM3.0) interface in, ClassVisitor class that is to say a kind of interface class.
Dynamic pitching pile is dynamic I nstrumentation, and in one possible implementation, this step 503 can lead to
Process shown in following step 31-33 is crossed to realize.
Step 31, the target device define the second target class, and second target class is for realizing acting on behalf of principal function.
Acting on behalf of principal function is agentmain function, and technical staff can write the code of the second target class, the mesh in advance
Marking device is compiled the code of second target class, generates the file of second target class, in the file of the second target class
Program for realizing agentmain function.
Step 32, the target device are based on the first object bytecode, realize that class file converts (Class File
Transformer) interface rewrites conversion (transform) function.
The target device can be come real by writing class (ClassReader) and reading class (ClassWriter) in ASM
Now this step 32.In one possible implementation, this step 32 can be by process shown in step 3201-3205 come real
