Question

我最近在Google App Engine上从Google Cloud Endpoints v1升级到v2。在更新之前，我的Android模拟器可以连接到GAE的localhost实例（与Eclipse一起运行），但是现在当我尝试访问本地URL时会显示此错误。有人可以建议吗？

HTTP ERROR 500

Problem accessing /_ah/api/. Reason:

    Failed to retrieve API configs with status: 500
Caused by:

java.io.IOException: Failed to retrieve API configs with status: 500

我的pom.xml已启用这两个配置，我认为这与连接到localhost有关：

<address>0.0.0.0</address>
<port>8080</port>

在Eclipse控制台中，还会产生此错误：

[INFO] GCLOUD: WARNING: /_ah/spi/BackendService.getApiConfigs
[INFO] GCLOUD: java.lang.NullPointerException

无法连接到localhost Google App Engine
