使用Sping Boot 27.9与Spring OAuth2和Google Auth沿着创建网站。当我尝试访问该网站时，我得到了上面的错误。我已经追溯了一点，但希望听到有人谁知道代码更好地帮助我确定什么是错的。下面是异常堆栈跟踪。

看起来错误在下面的语句中：

secDomain = (String) properties.get("security-domain");

并且似乎“属性”为空。这一行的代码是这样的：

SecurityContext securityContext = SecurityActions.getSecurityContext();
if (securityContext != null)
{
   secDomain = securityContext.getSecurityDomain();
}
else{
   secDomain = (String) properties.get("security-domain");

所以我假设securityContext是null，而且不应该是null。顺便说一句，这段代码只是我在网上找到的，没有做Git pull。
什么会导致SecurityActions。getSecurityContext（）返回null？
另外，作为一个附带说明，除了调用getAuthContext（）的方式之外，我们不会有NPE。我认为这是发生在www.example www.example.com ，下面是一个代码片段：

private JaspicState getJaspicState(AuthConfigProvider jaspicProvider, Request request, Response response,
        boolean authMandatory) throws IOException {
...
    try {
        CallbackHandler callbackHandler = getCallbackHandler();
        ServerAuthConfig serverAuthConfig = jaspicProvider.getServerAuthConfig("HttpServlet", jaspicAppContextID,
                callbackHandler);
        String authContextID = serverAuthConfig.getAuthContextID(jaspicState.messageInfo);
        jaspicState.serverAuthContext = serverAuthConfig.getAuthContext(authContextID, null, null); <--- Passing in null for properties
    } catch (AuthException e) {
        log.warn(sm.getString("authenticator.jaspicServerAuthContextFail"), e);
        response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
        return null;
    }
