我有一个 Spring MVC 应用程序，可以使用 Master/Slave 数据存储在 GAE 上运行。
我创建了一个配置了高复制数据存储的新应用。
现在，同一个应用程序将无法在这个新环境中启动。
我不知道这个堆栈跟踪表明启动失败的原因是什么:
org.springframework.web.servlet.FrameworkServlet initServletBean: Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [/base/data/home/apps/s~APPID/RESOURCEID/WEB-INF/classes/com/APPNAME/test/Test.class]; nested exception is com.google.apphosting.api.DeadlineExceededException: This request (REQUESTID) started at 2011/09/01 17:04:04.107 UTC and was still executing at 2011/09/01 17:04:54.208 UTC.

有人知道问题可能是什么吗？
最佳答案
我大胆猜测您在糟糕的时刻点击了 GAE，并且在读取 XML 配置文件时超时了。如果是这样的话，那么这与应用程序是 M/S 还是 HR 无关，而与糟糕的时机有关。从那以后你还能运行它吗？
关于java - 无法在 GAE HR 数据存储上启动 Spring MVC 3.0 应用程序，但可以在主/从属上运行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7311577/
