Detailed Description
The technical solutions of the present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
The basic idea of the invention is to adopt at least two micro-services, and the at least two micro-services upload respective service information to a registration center; when a service is called, judging whether service information of the called micro service exists in a local cache, if not, acquiring the service information of the called micro service from a registration center, and calling the corresponding micro service according to the service information of the called micro service; if the micro services exist, the corresponding micro services are called according to the service information of the called micro services cached locally, the micro services with different functions are deployed separately, the deployment times are reduced, the influence of BUG is reduced, and the experience of a user is improved.
Based on the above idea, the present invention proposes to include a registry and at least two microservices, as shown in fig. 1. At least two micro-services upload respective service information to a registration center; when a service is called, judging whether service information of the called micro service exists in a local cache, if not, acquiring the service information of the called micro service from a registration center, and calling the corresponding micro service according to the service information of the called micro service; if so, calling the corresponding micro service according to the service information of the called micro service cached locally.
In this embodiment, the invention adopts at least two micro services, and realizes the application of different micro services by adopting registration and calling modes, and the micro services with different functions are separately deployed, thereby reducing the deployment times, reducing the influence generated by the BUG, and improving the experience of the user.
When the micro service is started for the first time, the self-owned service information (IP, port and owned service list of the current service) is sent to the registration center. And if the registration center does not exist, adding the micro service into a heartbeat polling list, wherein the last timestamp is the current time. And if the registration center has the micro service, the last time stamp of the micro service in the registration center is the current time, so that the registration of the micro service is realized.
The registration center judges the timestamp of all the registered micro services at intervals, if the last update timestamp of the micro services is larger than the set detection intervals, for example, 3 detection intervals, the micro services are marked as off-line, and other micro services cannot take the off-line micro services again when acquiring service information next time, so that the occupied resources of the registration center are reduced.
The registration center updates or reads data by using a read-write lock mode, when the micro service is on line for registering or changing service information, the write lock is adopted, and when the information is not changed or a read request is carried out, the read lock is adopted for operation, so that the method is suitable for high flow and high concurrency.
No data interaction exists among the registries, strong consistency is not researched, and the final consistency is aimed at. Transient inconsistencies do not affect the overall microservice invocation, but can greatly improve performance.
And (3) the client queries the registration center, and after the query information fails, the client isolates the failed registration center and preferentially requests other normal registration centers by adopting a combined mode of load balancing and retry.
The client-side orders the time consumption of each request for obtaining the registration information, and preferentially obtains the information from the registration center with smaller delay.
The registration center does not need data interaction with the registration center cluster, so that multiple registration centers can be directly expanded horizontally when the pressure of the registration centers is too high.
And each micro service sends heartbeat to the registration center at set time intervals to update the time stamp on the registration center, and meanwhile, if the micro service of the registration center changes, the required service information is pulled again.
When a service is called, judging whether service information of the called micro service exists in a local cache, if not, acquiring the service information of the called micro service from a registration center, and calling the corresponding micro service according to the service information of the called micro service; if so, calling the corresponding micro service according to the service information of the called micro service of the local cache, and combining the service information of the local cache and the service information of the registration center to realize the quick calling of the micro service.
Based on the above system embodiment, correspondingly, as shown in fig. 2, the present invention further provides that the method includes the following steps:
s1: at least two micro-services upload respective service information to a registration center;
s2: when a service is called, judging whether service information of the called micro service exists in a local cache, if not, acquiring the service information of the called micro service from a registration center, and calling the corresponding micro service according to the service information of the called micro service; if so, calling the corresponding micro service according to the service information of the called micro service cached locally.
In an embodiment, the registration center judges whether the uploaded service information exists, if not, the corresponding micro service is added into a heartbeat polling list, the last timestamp is the current time, and if so, the last timestamp of the corresponding micro service in the registration center is updated to be the current time.
In an embodiment, at least two micro services respectively send a heartbeat to the registration center at set time intervals to update the last timestamp on the registration center, and if the service information of the registration center changes, the service information required by the micro services is obtained again.
In an embodiment, the registration center performs timestamp judgment on all currently registered micro-services at intervals, and if micro-services with last updated timestamps larger than a set number of detection intervals exist, marks the corresponding micro-services as offline.
In one embodiment, the micro service cannot acquire the service information of the offline micro service.
The specific schemes and the beneficial effects based on the method embodiments are all described in the system embodiments, and therefore, the detailed description is omitted.
Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
