本人剛接觸dubbo，想針對dubbo調(diào)取服務因網(wǎng)絡等故障失敗時這一異常做相應的補償機制------用本地接口實現(xiàn)類代替遠程接口實現(xiàn)類，在網(wǎng)上看到有用mock=“ture”的配置實現(xiàn)，嘗試了一通，但是失敗了，報如下錯誤：

java.lang.IllegalStateException: Failed to check the status of the service com.dcits.jk.TJCount. No provider available for the service com.dcits.jk.TJCount from the url zookeeper://192.168.1.130:2181/com.alibaba.dubbo.registry.RegistryService?application=consumer&dubbo=2.5.3&interface=com.dcits.jk.TJCount&methods=gettotal&mock=true&pid=10528&side=consumer&timestamp=1513235485333 to the consumer 192.168.1.116 use dubbo version 2.5.3

at com.alibaba.dubbo.config.ReferenceConfig.get(ReferenceConfig.java:138) ~[dubbo-2.5.3.jar:2.5.3]

我的服務接口如下：

public interface TJCount {
    public int gettotal() throws InterruptedException;
}
當服務調(diào)取失敗時，本地接口實現(xiàn)類如下：
public class TJCountMock implements TJCount {
    public TJCountMock(){
    }
    public int gettotal() throws InterruptedException{
        return 10;
    }
}

消費者接口配置如下：

<dubbo:reference id="tjcount" interface="com.dcits.jk.TJCount" mock="true"/>

請各位賜教。。
