Question

将application.properties中的servlet版本更新为2.5对生成的web.xml没有影响。生成的web.xml仍然是2.4版。我正在使用Grails 1.2.1。

app.servlet.version=2.5

另外，如果我尝试执行“run-app”，我会得到以下例外：

Running Grails application..
Starting AppEngine generated indices thread.
Starting reload monitor thread.

如何解决这些问题？

Answer 1

在servlet版本中进行更改后，您是否尝试过grails clean？至少它可以在我的机器上运行（grails 1.2.0）。

Grails + GAE - 使用app.servlet.version = 2.5发行
