Based on the routing rule of service interface;
Based on the routing rule of method of servicing;
Based on the routing rule of the parameter value of service;
Based on the routing rule corresponding to the affiliated machine room of service.
Particularly, routing rule comprises the routing rule based on service interface.At this, the routing rule based on service interface is service call according to interface route to several fixing machines or several groups of machines.Such as, user wants to do interface level route test to service A, and the address list of A service is: 192.168.1.2,192.168.1.3.When controlling all service access A service, be all routed to 192.168.1.3, only need to register following content to file configuration center:
IP address wherein support regular expression (*,?), such as can be configured to 192.168.1.*.At this, if only want to mate some IP, need to add ": * " after this IP during configuration, ": the * " part as above in example in " 192.168.1.3:* " is necessary.If natively there is asterisk wildcard " * " at the end of IP address, as 192.168.1.*, then without the need to adding again ": * ".
Routing rule also comprises the routing rule based on method of servicing.At this, the routing rule based on method of servicing is that the method for servicing that will call according to service invocation request screens candidate's available service, is routed to fixing several or several groups of machines.The same with the above-mentioned routing rule based on service interface, as user needs read and write abruption, existing 2 machines provide the read and write method of same service, and user thinks that 1 machine is used as the service of reading, 1 machine is used as the service of writing, and only needs to register following content to file configuration center:
Routing rule also comprises the routing rule of the parameter value based on service.At this, the routing rule based on the parameter value of service is the actual value that service call imports into according to parameter, is routed to several fixing machines or several groups of machines.User wants to do parameter rank route test to service A, and the address list of A service is: 192.168.1.2,192.168.1.3.Control all service access A when serving, if (such as, import integer into when parameter and be greater than 10 to a few machines, be less than 10 to another several machines) when certain parameter is greater than certain rule in method, be routed on different group machine.Only need to register following content to file registration center:
Routing rule also comprises based on the routing rule corresponding to the affiliated machine room of service.Preferably, when the available proportion threshold value of satisfied service, the preferential routing rule of local machine room is enabled.Because the cost across machine room is general larger, therefore, can preferentially enable local machine room.But because some services is unbalanced in the deployment of machine room, even do not dispose at some machine room, therefore, can not call with without exception full forbidding across machine room, calling across machine room is needs under certain conditions at all.The judgement carrying out weighing can be coordinated by local machine room is regular flexibly.At this, serve available proportion threshold value and be used for judging whether preferentially to enable local machine room, its value can be system intialization, also can adjust according to actual conditions.The available proportion threshold value of this service specifies in this routing rule certain service, whether enables the strategy that local machine room preferentially calls, and when enabling strategy, the threshold values that strategy really can come into force.It is defined as follows:
<flowControl>
<localPreferredSwitch>on</localPreferredSwitch>
<threshold>0.2</threshold>
</flowControl>
Above Rule Expression, enable to configured service the strategy that local machine room preferentially calls, taking effect rules threshold values is 0.2.
Rules properties:
localPreferredSwitch：on|off
Threshold:float value
Exclusions: if expect that this rule only comes into force to a part of machine, can use this attribute configuration to need the IP got rid of, as: 172.24.*, will represent that this rule can not be applied to the IP of all 172.24 beginnings.
The computational methods of the available proportion threshold value of this service are: serve available ratio=local machine room available machines used quantity/all service-delivery machine quantity.
When serving available ratio and being more than or equal to the available proportion threshold value of this service, enable local machine room preference strategy.When serving available ratio and being less than the available proportion threshold value of this service, local machine room preference strategy is closed, and service still adopts the mode of random call.
Those skilled in the art will be understood that above-mentioned routing rule is only citing, and other routing rules that are existing or that may occur from now on, as being applicable to the application, also should being included within the application's protection range, and being contained in this at this with way of reference.
Preferably, according to the address of service information of service invocation request and described one or more available service, and combine corresponding routing rule, determine that described target available service comprises:
According to the address of service information of service invocation request and described one or more available service, and combine corresponding routing rule and the weight information of described routing rule, determine described target available service.
Particularly, combine corresponding routing rule at the second device 102, when determining target available service, also can consider the weight information of routing rule.Such as, the second device 102 according to service invocation request, and first device 101 the address of service information of one or more available service that obtains or upgrade, and combine corresponding routing rule and the weight information of this routing rule, determine this target available service.
At this, owing to increasing weight in routing rule.User sometimes wishes that the inside increases weight again in routing rule, as long as at this moment at the routing rule of correspondence, as increased weighted value in the routing rule based on service interface, the routing rule based on method of servicing or the IP address list based on the routing rule of the parameter value of service.Such as, in based on the routing rule of service interface, increase weight information, ratio is 1:3.Then should be as follows based on the routing rule reference of service interface:
Preferably, the routing rule of described correspondence comprises multinomial routing rule; Wherein, according to the address of service information of service invocation request and described one or more available service, and combine corresponding routing rule, determine that described target available service comprises:

Particularly, routing rule comprises the routing rule based on service interface.At this, the routing rule based on service interface is service call according to interface route to several fixing machines or several groups of machines.Such as, user wants to do interface level route test to service A, and the address list of A service is: 192.168.1.2,192.168.1.3.When controlling all service access A service, be all routed to 192.168.1.3, only need to register following content to file configuration center:
IP address wherein support regular expression (*,?), such as can be configured to 192.168.1.*.At this, if only want to mate some IP, need to add ": * " after this IP during configuration, ": the * " part as above in example in " 192.168.1.3:* " is necessary.If natively there is asterisk wildcard " * " at the end of IP address, as 192.168.1.*, then without the need to adding again ": * ".
Routing rule also comprises the routing rule based on method of servicing.At this, the routing rule based on method of servicing is that the method for servicing that will call according to service invocation request screens candidate's available service, is routed to fixing several or several groups of machines.The same with the above-mentioned routing rule based on service interface, as user needs read and write abruption, existing 2 machines provide the read and write method of same service, and user thinks that 1 machine is used as the service of reading, 1 machine is used as the service of writing, and only needs to register following content to file configuration center:
Routing rule also comprises the routing rule of the parameter value based on service.At this, the routing rule based on the parameter value of service is the actual value that service call imports into according to parameter, is routed to several fixing machines or several groups of machines.User wants to do parameter rank route test to service A, and the address list of A service is: 192.168.1.2,192.168.1.3.Control all service access A when serving, if (such as, import integer into when parameter and be greater than 10 to a few machines, be less than 10 to another several machines) when certain parameter is greater than certain rule in method, be routed on different group machine.Only need to register following content to file registration center:
Routing rule also comprises based on the routing rule corresponding to the affiliated machine room of service.Preferably, when the available proportion threshold value of satisfied service, the preferential routing rule of local machine room is enabled.Because the cost across machine room is general larger, therefore, can preferentially enable local machine room.But because some services is unbalanced in the deployment of machine room, even do not dispose at some machine room, therefore, can not call with without exception full forbidding across machine room, calling across machine room is needs under certain conditions at all.The judgement carrying out weighing can be coordinated by local machine room is regular flexibly.At this, serve available proportion threshold value and be used for judging whether preferentially to enable local machine room, its value can be system intialization, also can adjust according to actual conditions.The available proportion threshold value of this service specifies in this routing rule certain service, whether enables the strategy that local machine room preferentially calls, and when enabling strategy, the threshold values that strategy really can come into force.It is defined as follows:
<flowControl>
<localPreferredSwitch>on</localPreferredSwitch>
<threshold>0.2</threshold>
</flowControl>
Above Rule Expression, enable to configured service the strategy that local machine room preferentially calls, taking effect rules threshold values is 0.2.
Rules properties:
localPreferredSwitch：on|off
Threshold:float value
Exclusions: if expect that this rule only comes into force to a part of machine, can use this attribute configuration to need the IP got rid of, as: 172.24.*, will represent that this rule can not be applied to the IP of all 172.24 beginnings.
The computational methods of the available proportion threshold value of this service are: serve available ratio=local machine room available machines used quantity/all service-delivery machine quantity.
When serving available ratio and being more than or equal to the available proportion threshold value of this service, enable local machine room preference strategy.When serving available ratio and being less than the available proportion threshold value of this service, local machine room preference strategy is closed, and service still adopts the mode of random call.
