Technical Field

The present application relates to the field of internet technologies, and in particular, to a method, an apparatus, a device, and a storage medium for invoking a service.

Background

With the development of internet technology, services, such as online payment, getting coupons, etc., are increasingly available in networks. In addition, there are more and more users who invoke services on the network.

In the prior art, the use of various services by users in a network is realized by means of a service call framework. The service calling framework comprises a service provider, a registration center and a service consumer, wherein the service provider registers the service provided by the service provider in the registration center, when the service consumer needs to call the service, the service consumer can search the service needed by the service provider in the registration center, the registration center can send an address list of the service provider providing the corresponding service to the service consumer, and the service consumer selects an address according to the address list and accesses the corresponding service provider to call the corresponding service.

In the process of implementing the present application, the inventor finds that the prior art has at least the following problems:

the service provider is implemented based on a JVM (Java Virtual Machine), and due to a memory management mechanism of the JVM, each time a service consumer calls a service from the service provider, the service consumer occupies a certain memory of the service provider, and after the occupied memory of the service provider is too much, memory garbage processing is performed, that is, the memory of the service provider is cleaned, and the service provider performing garbage collection suspends providing services to the service consumer, and continues providing services to the service consumer after garbage collection is completed.

Fig. 5 is a flowchart illustrating interaction among a computer device, a first server, and a second server in a method for invoking a service according to an embodiment of the present disclosure. Referring to fig. 5, the embodiment includes:

step 501, monitoring the memory usage of the first server

The first server may correspond to a service provider in the service invocation framework, the first server may be a server cluster, the server cluster includes a plurality of servers, and each server may serve as a service provider.

In an implementation, the memory in the service provider may be allocated as a younger generation memory, an older generation memory. Each time a computer device (service consumer) invokes a service in a service provider, it will take up a certain amount of older generation memory. Technicians can set a monitoring program in the service provider to monitor the usage amount of the memory of the middle-aged and the old age of the service provider.

Step 502, when the memory usage amount of the first server reaches the usage amount threshold, the memory garbage processing is started.

In implementation, when the old generation memory of the service provider has a trigger threshold, that is, after the usage amount of the old generation memory of the service provider reaches the trigger threshold, a Full GC (garbage collection) is automatically triggered to clean the old generation memory. The technician may additionally set a usage threshold in the service provider, wherein the usage threshold is less than the trigger threshold. When the monitoring program monitors that the usage amount of the memory of the old generation of the server provider reaches the usage amount threshold, the monitoring program can force the service provider to trigger the Full GC to clean the memory of the old generation.

Optionally, when the memory usage amount of the first server reaches the usage amount threshold, a period of time may be waited, and then the memory garbage processing is started, and the corresponding processing to the step 502 may also be as follows: and when the duration that the memory usage of the first server reaches the usage threshold reaches the duration threshold, starting to process memory garbage.

In implementation, a time length threshold may be preset, and after the monitoring program monitors that the usage amount of the memory of the old generation of the server provider reaches the usage amount threshold, the monitoring program may force the service provider to trigger a garbage collection processing mechanism to clean the memory of the old generation after the preset time length threshold passes.

In step 503, the first server sends a first indication message to the second server, where the first indication message is used to indicate the first server to start memory garbage processing.

The second server corresponds to a registration center in the service invocation framework, and the first indication message may carry address information and state information of a service provider that sends the first indication message.

In implementation, the technician may set a corresponding status information for each service provider, where the corresponding status information may be an unavailable status when the service provider cleans the old generation memory, and the corresponding status information may be an available status when the service provider does not clean the old generation memory. After the monitoring program monitors that the usage amount of the memory of the old generation of the server provider reaches the usage amount threshold value, the service provider can send a first indication message to the registration center, wherein the first indication message comprises a first indication message. The first indication message carries address information of the service provider and status information of the unavailable status.

Optionally, when the first server completes the memory garbage processing, a second indication message is sent to the second server, where the second indication message is used to indicate that the first server has completed the memory garbage processing.

In an implementation, after the first server finishes cleaning the old age memory, the monitoring program may further detect a usage amount of the old age memory of the server provider, and when the usage amount of the old age memory of the server provider is lower than a usage amount threshold, the service provider may send a second indication message to the registry, where the second indication message indicates that the old age memory of the server provider is not used. The second indication message carries address information of the service provider and status information of the available status.

In step 504, the second server receives the first indication message sent by the first server, and determines a server list corresponding to the target service provided by the first server.

Wherein, the server list records the server for providing the target service.

In implementation, when the service provider starts, the service provider may register a service provided by itself with the registry, that is, the service provider may send address information of itself and a provided service identifier to the registry, the registry may generate an address list by corresponding all the received address information and service identifiers, and may generate and store an address list for all the address information corresponding to each service identifier, that is, generate a server list. After receiving the first indication message sent by the service provider, the registry may determine all server lists including the address information carried in the first indication message according to the address information of the service provider carried in the first indication message.

In step 505, the second server sends a first indication message to the computer device that has sent the server list.

The computer device may be a service consumer in the service invocation framework, and may be a terminal or a server.

In implementation, a service consumer may send an inquiry request of a service to be invoked to a registry, where the inquiry request may carry a service identifier of the service to be invoked, and the registry may send a corresponding server list to the service consumer according to the service identifier. The service consumer may store the service identification with a corresponding server list. After receiving the first indication message and determining the server list containing the address information carried in the first indication message, the registry may determine, according to the stored information of the stored sending server list, the service consumer storing the server list containing the address information carried in the first indication message, and then send the first indication message to the corresponding service consumer.

Optionally, corresponding to the second indication information sent by the first server in step 503, after receiving the second indication information, the second server may perform the following processing: receiving a second indication message sent by the first server, wherein the second indication message is used for indicating that the first server has finished the memory garbage processing; determining a server list corresponding to a target service provided by a first server; and sending a second indication message to the computer equipment which has sent the server list.

Wherein, the server list records the server for providing the target service.

In an implementation, after the first server completes the memory garbage processing, a second indication message may be sent to the registry, where the second indication message carries address information of the service provider and state information of the available state. The registry receives a second indication message sent by the service provider, determines a server list corresponding to the service provided by the first server according to address information carried by the second indication message, wherein the server list comprises address information of all service providers providing the target service, and sends the second indication message to the computer equipment which has sent the server list.

In step 506, the computer device receives the first indication message sent by the second server, and masks the first server in a locally stored server list including the first server.

The first indication message is used for indicating the first server to start memory garbage processing.

In implementation, a service consumer receives a first indication message sent by a registration center, and performs shielding processing on address information carried in the first indication information in an address list which is locally stored and includes the address information carried in the first indication information, so that the service consumer does not call the address information carried in the shielded first indication information when calling a service.

Alternatively, the first server may be masked in the following two ways.

The first method is as follows: the first server is deleted from a locally stored list of servers that includes the first server.

In an implementation, as shown in fig. 11, the address information carried in the first indication information may be deleted in a locally stored server list, that is, the server that is performing memory garbage processing is deleted.

The second method comprises the following steps: in a locally stored server list including a first server, a pause call flag is added for the first server.

In implementation, as shown in fig. 12, state information of a corresponding server may be added after address information carried in first indication information in a locally stored server list, and an available state corresponding to the address information may be changed to an unavailable state in a shielding manner.

In step 507, when the computer device monitors a call trigger event of the target service corresponding to the server list, a third server is selected from the servers recorded in the server list except the first server, and the target service is called to the third server.

In implementation, the service consumer triggers a call trigger event of the corresponding service, that is, when the service consumer needs to call the corresponding service to the service provider, for example, a user operates a terminal to pay an order, or when another server needs to obtain data from a dependent service, the service consumer may call a corresponding task to the third server, that is, the service consumer may select address information corresponding to the server that is not shielded from a locally stored server list, access the selected server corresponding to the address information, and call the corresponding service, for example, complete payment of the order and related information records.

Optionally, corresponding to the second indication information sent by the second server in step 505, after receiving the second indication information, the service consumer may perform the following processing:

receiving a second indication message sent by a second server, wherein the second indication message is used for indicating that the first server has finished the memory garbage processing; unmasking the first server in a locally stored server list comprising the first server; and when a calling trigger event of the target service corresponding to the server list is monitored, selecting a fourth server from the servers recorded in the server list, and calling the target service to the fourth server.

In implementation, the service consumer receives second indication information sent by the registry, wherein the second indication information carries address information of the service provider and state information of the available state. And the service consumer determines a locally stored server list containing the address information carried by the second indication message according to the address information carried by the second indication message, and shields the corresponding server before the corresponding server list is cancelled.

When the service consumer needs to call the corresponding service to the service provider, the service consumer may call the corresponding task to the fourth server, that is, the service consumer may select the address information corresponding to the unmasked server from the locally stored server list, access the server corresponding to the selected address information, and call the corresponding service.

Optionally, the two shielding manners for the first server in step 506 may correspond to manners of canceling shielding the first server, which respectively are:

the first method is as follows: adding the first server in a locally stored server list comprising the first server.

In implementation, as shown in fig. 13, the address information carried in the first indication information may be added to a server list locally stored by the service consumer, that is, a server that has completed memory garbage processing is added.

The second method comprises the following steps: as shown in fig. 14, the pause call flag of the first server is canceled in a locally stored server list including the first server.

In implementation, the state information of a corresponding server may be added after the address information carried in the first indication information in the locally stored server list, and the unavailable state corresponding to the address information may be changed to the available state in a manner of canceling the shielding.

According to the embodiment of the application, the usage amount of the memory of the old generation in the service provider is monitored, when the usage amount of the memory of the old generation of the service provider exceeds the set usage amount threshold, the memory garbage processing is carried out on the memory of the old generation, the indication message is sent to the registration center, the indication message is sent to the service consumer by the registration center, and the service consumer avoids calling the service provider which carries out the memory garbage processing according to the indication message, so that the problem that the service calling duration is increased due to calling the service provider which carries out the memory garbage processing can be avoided.

All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.
