Fig. 2 is a data interaction flow chart provided in conjunction with the data update system shown in fig. 1A, fig. 1B and fig. 1C, and referring to fig. 2, a data interaction flow provided by an embodiment of the present invention includes:
201. and after detecting the updating instruction, the service management server forwards the updating instruction to the target service server.
In the embodiment of the present invention, in the process of managing the system, an original service unit in the system needs to be modified, replaced, or a new service unit needs to be added, for example, a bug occurs in the system, a service logic changes, a transmission protocol changes, a new function is added, and the like. In order to distinguish different service units and facilitate management, each service unit is generally labeled with version information, and service units having the same identification information may have different version information.
When data updating is performed, firstly, a developer needs to upload a data packet to be updated to a file server through a computer, and the data packet to be updated may include a plurality of service modules to be updated. And then, the operation and maintenance personnel can call a command line input window of the service management service through the display equipment and input an updating instruction in the command line input window, wherein the updating instruction comprises the identification information of the data packet to be updated, and the identification information of the data packet to be updated at least comprises the packet name and the storage path of the data packet to be updated. And after detecting the updating instruction, the service management server reads the corresponding data packet to be updated in the file server according to the packet name and the storage path of the data packet to be updated contained in the updating instruction. And then, analyzing the data packet to be updated to obtain the service identifications of the plurality of service modules. For the service identifier of each service module, the service management server obtains the identifier information of the target service server corresponding to the service identifier of the service module from the configuration management list, and forwards the update instruction to the target service server corresponding to the identifier information of the target service server. The configuration management list stores the corresponding relationship between the identification information of the service server and the service identification of the service module.
It should be noted that, after the service management server obtains the identification information of the target service server corresponding to the service identification, the service identification is added to the update instruction, where the service identification at least includes the storage path of the service module to be updated. And then, the service management server forwards the updating instruction to the target service server through the controlled terminal matched with the identification information of the target service server. If the service module to be updated in the data packet to be updated is a newly added service module, that is, no service module corresponding to the service identifier of the service module to be updated exists on all current service management servers, the service module to be updated may be directly added with the identifier information of the service server corresponding to the service module to be updated, or a corresponding relationship between the service identifier of the service module to be updated and the identifier information of the service server may be added in advance in the service management server.
It should be noted that, because the data packet to be updated may include a plurality of service modules to be updated, and the plurality of service modules to be updated may need to be updated to different service servers, that is, the plurality of service modules to be updated correspond to different target service servers, the embodiment of the present invention only takes the data updating process of one target service server as an example for explanation.
202. And after receiving the updating instruction, the target service server acquires the corresponding service module to be updated from the file server according to the service identifier, and analyzes the service module to be updated to obtain the identifier information, the calling information and the version information of the new service unit.
In the embodiment of the invention, the target service server receives the update instruction sent by the service management server through the service management module in the container, and downloads the corresponding service module to be updated from the file server to the target service server according to the storage path of the service module to be updated, which is indicated by the service identifier in the update instruction. And then, the service management module analyzes the service module to be updated to obtain the identification information, the calling information and the version information of the new service unit. The service module to be updated may include a plurality of new service units or may include one new service unit, which is not specifically limited in this embodiment of the present invention. The calling information of the service unit is used for providing a calling inlet of the service unit, and the version information is used for distinguishing the service units with the same identification information.
203. And the target service server registers the calling information to the service response module according to the identification information of the new service unit, and registers the identification information and the version information of the new service unit to the distributed management server.
In the embodiment of the present invention, after the service management module analyzes the service module to be updated, for each new service unit in the module to be updated, the call information of the new service unit is registered to the service response module to replace the call information of the old service unit that is the same as the identification information of the new service unit, so that the new service unit is directly called when a subsequent service request is responded. When updating is performed according to a new service unit, the service management module firstly searches in the service response module whether registration information matched with the new service unit exists, that is, whether calling information of an old service unit matched with the identification information of the new service unit exists. If the service unit exists, the calling information of the new service unit is directly replaced by the calling information of the old service unit. Because the calling information matched with the service unit is unique in the service response module, after the calling information of the new service unit is registered to the service response module, if a corresponding service request is received, the new service unit can be directly called to respond, so that the service provided by the service unit does not need to be stopped firstly in the updating process of the service unit, and then the new service is provided by restarting, and the process is not sensible to the user, and the use of the user is not influenced. The registration information stored in the service response module may be implemented by a Map function mapped one by one, or implemented in other manners, which is not specifically limited in this embodiment of the present invention.
It should be noted that, if the service management module does not find the calling information of the old service unit matching the identification information of a new service unit in the service response module, it is determined that the new service unit is a newly added service unit, and the calling information of the new service unit is directly added to the service response module.
It should be noted that, after registering a new service unit in the service response module, the target service server needs to register the new service unit in the distributed management server for distributed management of the system, that is: after registering a new service unit to a service response module, a target service server sends an adding message of the new service unit to a distributed management server, wherein the adding message at least comprises identification information and version information of the new service unit; and the distributed management server stores the identification information and the version information of the new service unit as registration information according to the received adding message.
It should be noted that, when a service unit in the system is updated, in order to ensure that a new service unit can correctly respond to a service request, the function of the new service unit may be tested first, that is, the service corresponding to the new service unit is provided to a part of users first, and after the service requests of the part of users are correctly responded, the service corresponding to the new service unit is provided to all users. In order to achieve the above requirement, an embodiment of the present invention provides a gray scale mechanism, that is, a developer may set a gray scale value of a new service unit in the new service unit, where the gray scale value may be an assigned number segment, and indicates that the new service unit only responds to a service request corresponding to the assigned number segment. And when the service management module analyzes the service module to be updated, if the new service unit contains a gray value, storing the gray value. After a service server receives a service request, if it is detected that a new service unit corresponding to the service request is set with a gray value, judging whether a number corresponding to the service request is contained in an appointed number segment indicated by the gray value, and if so, responding to the service request; and if not, not responding to the service request.
204. After the calling information of the new service unit is registered in a service response module of a container in a target service server, the display device acquires the identification information and the version information of the new service unit from the distributed management server and displays the identification information and the version information of the new service unit on a service monitoring page.
In the embodiment of the invention, in order to monitor the state of the system in real time and to better manage and maintain the system, a display device is provided, and on a service monitoring page of the display device, identification information and port information of all service servers, identification information and version information of containers, identification information and version information of service units and calling times of the service units in the system are displayed. The identification information of the service server can be a physical address of the service server; different ports used by the service server when different data transmission is carried out can be obtained through the port information of the service server; the number of times of calling of the service unit indicates the number of times of responding to the service request by the service unit, and may include the number of times of successful response and the number of times of failed response.
It should be noted that the display device may be connected to the distributed management server, and the information displayed on the service monitoring page may be obtained by reading node information of the service server stored in the distributed management server. After the calling information of the new service unit is registered in the service response module of the container in the target service server, according to step 203, it can be known that the identification information and version information of the new service unit will be registered in the distributed management server, and the display device can read the identification information and version information of the new service unit from the distributed management server and display the read information on the service monitoring page. In addition, the service monitoring page may further provide an inquiry function, and the information of the designated service server or the information of the designated service unit is obtained through the inquiry function, which is not specifically limited in the embodiment of the present invention. When the display device detects the click operation of a query button on a service monitoring page, acquiring information to be queried; the display device sends the information to be inquired to the distributed management server, and the distributed management server returns a result matched with the information to be inquired. The information to be queried may be identification information of a service unit, port information of a service server, and the like, which is not specifically limited in this embodiment of the present invention. For example, if the information to be queried is identification information of a service unit, the distributed management server returns identification information, version information, call times, and the like of the service unit that matches the identification information.
205. And the target service server deletes the old service unit after detecting that the old service unit is in the state of not being called.
In the embodiment of the present invention, after the calling information of the new service unit is registered in the service response module, the old service unit corresponding to the new service unit may still be in a called state, and at this time, in order to ensure that the service request can be normally responded, the old service unit also needs to be retained in the service server. When the service server detects that the old service unit is converted from the called state to the non-called state, the old service unit is deleted, so that the old service unit does not occupy the memory, and the phenomenon that the memory is continuously increased in the process of continuously updating the service unit, and the updating efficiency is further influenced, is avoided.
It should be noted that, after the target service server deletes the old service module, the registration information of the old service module also needs to be deleted in the distributed management server, that is to say: after deleting the old service module, the target service server sends a deletion message of the old service unit to the distributed management server, wherein the deletion message at least comprises identification information and version information of the old service unit; and after receiving the deletion message, the distributed management server deletes the registration information of the old service unit according to the identification information of the old service unit contained in the deletion message.
In the system and the method provided by the embodiment of the invention, after detecting the update instruction, the service management server forwards the update instruction to the target service server, wherein the update instruction at least comprises the service identifier of the service module to be updated, and the target service server is used for providing service processing corresponding to the service identifier; after receiving the update instruction, the target service server acquires a service module to be updated from the file server according to the service identifier, and analyzes the service module to be updated to obtain identifier information, calling information and version information of a new service unit; the target service server registers the calling information to a service response module of a container in the target service server according to the identification information of the new service unit so as to replace the calling information of the old service unit which is the same as the identification information, so that the new service unit is directly called when the service request is subsequently responded. Because the updating can be completed without stopping the service when the service unit is updated, and the corresponding service request is not influenced, the data updating mode can be updated in any time period, and has high flexibility, short updating time and simple and convenient steps.
