Inserting method disclosed by the invention based on Eureka-Server project, belong to big data technical field, by using Eureka-Server serviced component, does not need additional infrastructural support, additional maintenance, configuration and server overhead etc. will not be generated, manpower and material resources cost are saved.A variety of checking routines are provided with during offline to offline project, can thoroughly stop to offline project process and make offline to offline project gracefulness.
Description
Technical field
The invention belongs to big data technical fields, and in particular to a kind of inserting method based on Eureka-Server project.
Background technique
Offline project framework is waited for using spring cloud mode in company parts rear end, in service registration to Eureka, with
Guarantee system 7 × 24 hours active.But it when offline project is issued, is needing to guarantee not requesting that the clothes can be distributed
Business device, otherwise user just can be appreciated that 404 or 505 mistake.So need the operation of one " offline ", want it is offline to
Offline item nodes are extractd from load balancing, so that entirely lower line process is enough gracefulnesses, to guarantee that front-end customer is sent
Unaware when request, at the same to offline project can complete process be assigned to the business datum on this node.
Currently, the inserting method to offline project mainly includes following several:
The first scheme: completed using Service Mesh (service grid environment) between offline project network call,
Current limliting, fusing and monitoring, reach the offline unaware of application program in issuing process, and generally major company is used；
Second scheme: being completed using kill java process, which by be that Spring Boot is applied
Shutdown hook, offline using itself are also graceful.Generally small-to-medium business is used；
The third mode: provided using Spring Boot/endpoints such as shutdown endpoint and/pause realize under
The gracefulness of line project is offline.
These three schemes have the following deficiencies:
(1) Service Mesh has enough advantages, and disadvantage is also relatively more clear.Service Mesh is used also in evolution
Scene is complicated, need to put into huge manpower and material resources come present environment is transformed, to offline project etc., when necessary must be for enterprise
The specifically used scene of industry carries out secondary development.
(2) kill java process and Spring Boot provide /shutdown endpoint, which by be
The Shutdown hook of Spring Boot application, offline using itself are also gracefulness, but if the clothes to offline project
Business discovery component uses Eureka-Server, then default longest delay in 90 seconds, other wait for that offline project can just perceive
It is offline to the service, it is intended that in 90 seconds after the example is offline, it is offline that other services still can be capable of calling this
To offline project, it is also possible to because certain reasons cause process Hang to lead to not thoroughly stop the process.
(3) Spring Boot provide /pause endpoint, only can will it is offline to offline project mark be DOWN, no
Can really it stop.
Summary of the invention
In view of the defects existing in the prior art, the embodiment of the invention provides a kind of based on Eureka-Server project
Inserting method, method includes the following steps:
According to offline project name, obtain to offline item destination slogan；
According to the port numbers, whether the described judgement to offline project is to be registered on Eureka-Server to offline item
Mesh, if so, obtaining the status flags information to offline project；
If the status flags information is UP, by sending POST request to pause endpoint, circulation triggers offline reality
Example, is changed to DOWN for the status flags information to offline project；
It checks to offline project log, judges whether become zero in the set time period to offline item target flow, if it is not,
" kill " order is then executed, transmission SIGTERM signal extremely to the corresponding process of offline project and judges the process in setting
Whether stop in period, if it is not, then executing " kill-9 " order, sends SIGKILL signal to the process until to offline
Project is offline.
Preferably, the method also includes:
By mail feedback to offline project name, to the offline IP of offline project, to the offline executor of offline project and to
The offline offline implementing result of project.
Preferably, judging whether the port numbers provided are consistent with the port numbers of acquisition includes:
If inconsistent, terminate offline to offline project and fed back by mail to the offline rank executed at present of offline project
Section and terminate the reason offline to offline project.
Preferably, judgement it is described to offline item target flow in the set time period with the presence or absence of including:
If so, terminate it is offline to offline project and fed back by mail to the offline project offline stage executed at present and
Terminate the reason offline to offline project.
Preferably, according to offline project name, obtain registered on Eureka-Server to offline project information
Before, the method also includes:
Modify Eureka Server configuration file, comprising:
Close self-protection mode；
Active failure detection times interval is set.
Preferably, according to offline project name, obtain registered on Eureka-Server to offline project information
Before, the method also includes:
Modification is to offline project profile, comprising:
Setting service expired time interval；
Setting service refresh time；
The periodic refreshing local cache time is set；
The ribbon cache flush time is set；
Enable pause endpoint.
Inserting method provided in an embodiment of the present invention based on Eureka-Server project has the advantages that
Using Eureka-Server serviced component, additional infrastructural support is not needed, additional maintenance will not be generated, matched
It sets and server overhead etc., saves manpower and material resources cost；
A variety of checking routines are provided with during offline to offline project, can thoroughly be stopped to offline project process simultaneously
So that offline to offline project gracefulness.
