WSO2 API管理器/ services /…抛出NullPointerException

Question

我在Windows 2012 R2服务器上运行了WSO2 API管理器，并且所有仪表板URL都很好，例如https://localhost:9443/store ， https://localhost:9443/carbon ， https://localhost:9443/publisher 。 但是，当我配置并部署（在carbon.super租户中）示例WeatherAPI Web服务并尝试通过/services/... URL来访问它时，即：

https://localhost:9443/services/weather/1.0.0/*?q=Amsterdam

我得到以下错误页面返回：

当我在租户中创建自己的Web服务并进行部署时，会出现相同的错误。 所以我可能配置错误，但不知道在哪里看。 /services/...下的所有路径似乎都返回此错误页面。 我检查了[WSO2]/repository/logs目录中的[WSO2]/repository/logs文件，但是它们没有显示任何错误。

您尝试从servlet端口9443访问服务。尝试使用8280端口 。 但是，APIM中的API端点看起来并不像您提到的那样。 查看官方WSO2文档中给出的示例
