Question

我通过eclipse在本地运行Google Apps。我连接到http://localhost:8888/，有时Eclipse将从AccessControlContext.class中的第374行引发异常：

    throw new AccessControlException("access denied "+perm, perm);

这是堆栈跟踪：

Logger.warning(String) line: 1026

我正在说这个：

    log.warning("string");

和log初始化如下：

    private static final Logger log = Logger.getLogger(MyServletName.class.getName());

什么是破碎？

Answer 1

请尝试使用此行。当我编写GAE代码时，我通常使用类似于以下行的内容：

private static final Logger log = Logger.getLogger(MyServletName.class.getSimpleName());

因此，请使用getSimpleName()代替getName()。阅读getName()和getSimpleName()上的java.lang.Class javadoc。前者可能在类类型名称的末尾附加一个“L”字符，而后者不具有此（在您的情况下，不合需要的）行为。

另外，请考虑使用 Guice Injection 作为类的Logger对象。

为什么Logger会崩溃我的Google Apps JSP？
