It should be noted that, the service degradation dynamic implementation method provided by the embodiments of the present application is generally implemented byServer/terminal Terminal equipmentImplementation, accordingly, the service degradation dynamic implementation means is generally arrangedServer/terminal deviceIn (1).
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continuing reference to FIG. 2, a flow diagram of one embodiment of a method for dynamic implementation of service downgrades is shown, according to the present application. The dynamic realization method for the service degradation comprises the following steps:
step S201, a service degradation message is received.
In this embodiment, the method for dynamically implementing service degradationElectronic devices running thereon (e.g. as shown in FIG. 1)Garment Server/terminal device) The service degradation message may be received through a wired connection or a wireless connection. It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
And the service degradation is the degradation of some services and pages with policies according to the current service condition and flow under the condition that the pressure of the server is increased, so that the server resources are released to ensure the normal operation of the core task. When the service calls other targets and the target returns data exception, the current service is triggered to degrade. The service degradation message refers to a message for performing service degradation on the current service triggered according to parameters contained in return data when target return data is abnormal.
The ways of service degradation include: page rejection service (i.e. page prompt service is busy), page delay service, interface rejection service (page is normally displayed, but addition and deletion operations cannot be performed), and the like.
Step S202, responding to the service degradation message, and acquiring degradation logic from a degradation container in a preset degradation plug-in.
In this embodiment, the downgrade plug-in is preset and decoupled from the core business code of the service. The preset degradation plug-in comprises a degradation container, and degradation logic is stored in the degradation container. And when receiving the service degradation message, reading the degradation logic from the degradation container in the preset degradation plug-in. Destaging logic is synchronized into a destaging container from a preset destaging logic configuration center. When the downgrade logic needs to be changed, a code writer or an operator uploads new downgrade logic or switches the downgrade logic to a preset downgrade logic configuration center, the downgrade logic configuration center sends a change notice, and the downgrade plug-in responds to the change notice, calls a synchronization thread and synchronizes the change of the downgrade logic to a downgrade container. By presetting the degradation plug-in and the degradation logic configuration center, the degradation logic is decoupled from the core service code of the service, so that the change of the degradation logic can be dynamically realized without recompiling the service code, and the service timeliness is improved.
Step S203, a preset dynamic compiler is called to dynamically compile the degradation logic, and generate a degradation class.
Compilation is the process of generating a target program from a source program written in source speech using a compiler program, i.e., translating a program written in a high level language into binary code executable by a computer. Static compiling: when compiling the executable file, the compiler extracts the part of the corresponding dynamic link library (.so or. ilb) which needs to be used, and links the part to the executable file, and all codes are embedded into the host program after compiling. Making the executable file not need to rely on a dynamically linked library at runtime.
The dynamically compiled executable file needs to be attached with a dynamically linked library, and when the dynamically compiled executable file is executed, a command in the corresponding dynamically linked library needs to be called. The method has the advantages of reducing the volume of the execution file, accelerating the compiling speed and saving system resources.
In this embodiment, the demotion logic is dynamically compiled by java compiler or java sist, and a demotion class is generated. Dynamic compilation of Java generates Java classes when a program runs.
And step S204, operating the degradation class to realize service degradation.
And loading the dynamically compiled degradation class into a memory and executing a degradation logic.
The method comprises the steps of receiving a service degradation message; responding to the service degradation message, and acquiring degradation logic from a degradation container in a preset degradation plug-in; calling a preset dynamic compiler, and dynamically compiling the degradation logic to generate a degradation class; and operating the degradation class to realize service degradation. The method comprises the steps of storing the degradation logic in a degradation container, decoupling the degradation logic code from the core service code, interfacing the degradation logic, versioning, multiplexing the degradation logic and switching versions. Meanwhile, the dynamic configuration of the degradation logic in the degradation container can switch the degradation logic in real time according to the service logic, so that the service requirement is met. The method solves the defects that the existing degradation scheme can not be dynamically switched and can not meet the service timeliness.
In some optional implementation manners of this embodiment, in step S201, the electronic device may further perform the following steps:
receiving return data of a service request target;
analyzing the returned data to obtain the state parameters of the request target;
and comparing the state parameter with a preset service degradation condition, and triggering a service degradation message when the state parameter is consistent with the service degradation condition.
In this embodiment, when the service requests another target, the return data of the target is analyzed to obtain the status parameter of the requested target. The state parameter is used to indicate whether the processing of the target end is normal or not, and which kind of problem occurs. And comparing the state parameter of the request target with a preset service degradation condition, and triggering a service degradation message when the state parameter in the received return data is consistent with the service degradation condition.
In some optional implementation manners, if the preset service degradation condition includes N service degradation rules, and each service degradation rule is in a preset matching relationship with the status parameter of the request target, in the step of comparing the status parameter with the preset service degradation condition, and triggering the service degradation message when the status parameter is consistent with the service degradation condition, the electronic device may further perform the following steps:
comparing the state parameters with preset service degradation conditions to obtain service degradation rules matched with the state parameters;
analyzing a degradation logic parameter in a service degradation rule, and writing the degradation logic parameter into a service degradation message;
triggering a service downgrade message including the downgrade logic parameter.
In this embodiment, the preset service degradation condition includes a plurality of service degradation rules, and each service degradation rule is in a preset matching relationship with the state parameter of the request target. The service degradation rules define a service degradation policy, and different service degradation logics are distinguished through degradation logic parameters, namely, different service degradation logics are adopted to perform service degradation for different state parameters of the current service. Therefore, different degradation logics can be set according to different states of the target, the possibility of normal operation of the service is improved under the condition that the server resources are in shortage, and the user experience is improved.
In some optional implementations, if the service degradation message includes interface information, in step S202, the electronic device may further perform the following steps:
and acquiring the degradation logic corresponding to the interface information from the degradation container according to the interface information.
In this embodiment, a service requests different targets through different interfaces, data communication between a server and a target includes interface information, and when data returned by the target is abnormal, the abnormal returned data is analyzed, a degradation message is triggered, and the interface information is written in the degradation message. And when responding to the degradation message, acquiring the degradation logic corresponding to the interface information from the degradation container according to the interface information. Therefore, different degradation logics are adopted for different target exceptions, service degradation is more targeted, the utilization rate of computer resources is improved, and user experience is improved.
In some optional implementations, before step S202, the electronic device may further perform the following steps:
receiving a configuration change notification sent by a preset degradation logic configuration center;
and responding to the configuration change notification, calling a synchronization thread, and synchronizing the configuration change of the downgrade logic configuration center to the downgrade container.
In this embodiment, a downgrading configuration center is preset, the downgrading configuration center is decoupled from a service core code, a storage of the downgrading configuration center may be (zookeeper, redis, mysql), and a storage technology is not limited, so that expansion is facilitated. And compiling the latest degradation logic by a degradation logic code writer according to the business requirements, and uploading the latest degradation logic to a degradation configuration center. When a code writer or an operator uploads new downgrade logic or switches downgrade logic, a configuration change notification is triggered, the configuration change notification is received, a synchronous thread is called, and a downgrade logic configuration center acquires updated downgrade logic and synchronizes the updated downgrade logic to a downgrade container.
In some optional implementation manners, if the configuration change notification includes an interface corresponding to an updated downgrade logic, in the step of receiving the configuration change notification sent by the preset downgrade logic configuration center, the electronic device may further perform the following steps:
analyzing the configuration change notification to obtain an interface corresponding to the updated degradation logic;
and calling a synchronization thread, and synchronizing the updated demotion logic into the demotion container according to the interface.
In this embodiment, the configuration change notification includes an interface corresponding to the updated destaging logic, and the updated destaging logic is synchronized to the destaging container according to the interface. The configuration change notification includes an interface corresponding to the updated downgrade logic, so that the synchronization process only needs to synchronize the downgrade logic for the interface, and the synchronization efficiency is improved.
In some optional implementation manners, if the configuration change notification further includes updated version information of updated downgrade logic, in the step of receiving the configuration change notification sent by the preset downgrade logic configuration center, the electronic device may further perform the following steps:
analyzing the configuration change notification to obtain updated version information of the updated downgraded logic;
reading current version information of the degradation logic corresponding to the interface in the degradation container according to the interface;
and comparing the updated version information with the current version information, calling a synchronization thread when the updated version information is inconsistent with the current version information, and synchronizing the updated downgrade logic into the downgrade container according to the interface.
In this embodiment, the configuration change notification further includes updated version information of the updated demotion logic. Reading the current version information of the downgrade logic corresponding to the interface in the downgrade container according to the interface, comparing the updated version information with the current version information, calling a synchronization thread when the updated version information and the current version information are not consistent, and synchronizing the updated downgrade logic into the downgrade container. When the two are identical, no synchronization is performed. By comparing the version information, when the version information is consistent, synchronization is not performed, so that unnecessary synchronization process and waste of computer resources are avoided. By presetting the degradation logic configuration center, wherein the stored degradation logic corresponds to the interface and contains version information, the degradation logic can be configured according to the interface and the version, and can be inquired according to the interface and the version, so that the visualization and the configurability of the degradation logic are improved.
