After the binding is successful, the printing unit 114 performs log printing based on the log printing plug-in when executing the target process.
In this embodiment, when no abnormal information is returned, it is indicated that the log printing plugin and the target process are successfully bound; and when abnormal information is returned, the log printing plug-in is successfully bound with the target process, and at the moment, the log printing plug-in can be bound again to ensure that log printing is normally executed.
In at least one embodiment of the present invention, the printing unit 114 performs log printing based on the log printing plug-in includes:
Acquiring an agent method and a printing method from the log printing plug-in;

executing the proxy method and the printing method in the virtual machine container to obtain a target class;
acquiring an initial class corresponding to the target class, and replacing the initial class by the target class;
and executing the target class, and performing log printing.
For example: the agentmain method (i.e., the proxy method) may be obtained from the log print plug-in dynamic-print-log.jar, and the print method associated with the agentmain method may be obtained at the same time, so that after the virtual machine container is started, the agentmain method and the print method may be executed, a new class may be generated and used as the target class, and further, an old class (i.e., the initial class) that is originally run may be replaced with the target class by using an instrumentation.
Wherein the virtual machine container may be a JVM (Java Virtual Machine ), the invention is not limited.
It can be appreciated that the environment of the production line has high requirements on the stability of the system, and if the running code is wrong, the normal running of the whole production line can be affected.

Obtaining the function name of the function corresponding to the newly added abnormal point as a newly added function name;
inquiring a process associated with the newly added function name from the obtained process and taking the process as a newly added process;
binding the log printing plug-in and the newly added process.
According to the embodiment, when the newly added abnormal point exists, the log printing is not needed to be executed again, and the log printing of the newly added abnormal point can be realized only by binding the function corresponding to the newly added abnormal point with the corresponding process, so that the printing efficiency is effectively improved, and meanwhile, the execution of the original log printing process is not influenced.
