目前我们正在尝试通过 WSO2 API 管理器公开我们的 Axis2 Web 服务。然而，在某些情况下，服务不返回结果并查看 WSO2 API 管理器上的日志，我们看到以下内容
ERROR {org.wso2.carbon.apimgt.gateway.handlers.throttling.APIThrottleHandler} - Unable to load throttling policy using key: gov:/apimgt/applicationdata/tiers.xml {org.wso2.carbon.apimgt.gateway.handlers.throttling.APIThrottleHandler} TID: [0] [AM] [2013-01-07 16:42:22,951]

对于配置，我使用默认的 h2 数据库作为用户和 api 管理器数据库的注册表和 mysql 数据库。
