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>

ConditionRouter It supports the conditional routing configured by "override://", in 2.6.x, refer to https://dubbo.apache.org/en/docs/v2.7/user/examples/routing-rule/ . For 2.7.x and later, please refer to org.apache.dubbo.rpc.cluster.router.condition.config.ServiceRouter and AppStateRouter refer to https://dubbo.apache.org/zh/docs/v2.7/user/examples/routing-rule/ .

ConditionStateRouter

public ConditionStateRouter(org.apache.dubbo.common.URL url,
                            String rule,
                            boolean force,
                            boolean enabled)

ConditionStateRouter

public ConditionStateRouter(org.apache.dubbo.common.URL url)

方法详细资料

init

public void init(String rule)

isRuntime

public boolean isRuntime()

从接口复制的说明: StateRouter

To decide whether this router need to execute every time an RPC comes or should only execute when addresses or rule change.

指定者:

isRuntime 在接口中 StateRouter<T>

覆盖:

isRuntime 在类中 AbstractStateRouter<T>

返回:

true if the router need to execute every time.

matchArguments

public boolean matchArguments(Map.Entry<String,org.apache.dubbo.rpc.cluster.router.condition.ConditionStateRouter.MatchPair> matchPair,
                              Invocation invocation)

analysis the arguments in the rule. Examples would be like this: "arguments[0]=1", whenCondition is that the first argument is equal to '1'. "arguments[1]=a", whenCondition is that the second argument is equal to 'a'.

参数:

matchPair -

invocation -

返回:
