Gradle任务tomcatRun成功，但Web应用程序抛出404错误

Question

我在Eclipse中有一个Spring MVC Web应用程序，它是我用Gradle构建的。我也在使用Gradle Tomcat插件。

当我运行GradletomcatRunWar任务时，一切都按预期进行，我的网络应用程序也会做出响应。但当我运行GradletomcatRun时，尽管它看起来很成功，并显示"服务器正在http://localhost:8080/，Web应用程序只抛出404个错误，并显示消息"请求的资源不可用"。

然后，我用-I（info）和-d（debug）选项运行Gradle任务，当我尝试访问服务器时，我看到以下内容：

如果我再等10秒左右，我就会看到：

Answer 1

即使您使用tomcatRun.webDefaultXml.

Answer 2

也许你应该删除tomcatRunWar.contextPath。我不确定"是否被部署为ROOT上下文。404表示战争没有部署到ROOT上下文中。如果您删除了contextPath，您应该能够调用http://localhost:8080/

Answer 3

我们需要在部署程序集中添加Web内容文件夹，因为Gradle默认情况下不会配置它。
