类 ConditionStateRouter<T>

java.lang.Object

org.apache.dubbo.rpc.cluster.router.state.AbstractStateRouter<T>

org.apache.dubbo.rpc.cluster.router.condition.ConditionStateRouter<T>

所有已实现的接口:

StateRouter<T>

public class ConditionStateRouter<T>
extends AbstractStateRouter<T>

Condition Router directs traffics matching the 'when condition' to a particular address subset determined by the 'then condition'. One typical condition rule is like below, with 1. the 'when condition' on the left side of '=>' contains matching rule like 'method=sayHello' and 'method=sayHi' 2. the 'then condition' on the right side of '=>' contains matching rule like 'region=hangzhou' and 'address=*:20881'

By default, condition router support matching rules like 'foo=bar', 'foo=bar*', 'arguments[0]=bar', 'attachments[foo]=bar', 'attachments[foo]=1~100', etc. It's also very easy to add customized matching rules by extending ConditionMatcherFactory and ValuePattern

--- scope: service force: true runtime: true enabled: true key: org.apache.dubbo.samples.governance.api.DemoService conditions: - method=sayHello => region=hangzhou - method=sayHi => address=*:20881 ...
