Java 本地tomcat中的GWT应用程序：未找到nocache.js 404

目前，我正在尝试构建（maven）并运行（Tomcat6.0.36）一个GWT应用程序。该应用程序在eclipse中运行良好，构建成功。tomcat启动期间没有问题

当我调用登录页时，我得到一个HTTP404错误，因为nochache.js文件不在那里。在分解的war目录中没有nochache.js文件是正确的。但是为什么呢？有什么想法吗

我的pom.xml中是否需要任何修改

您为gwt maven插件配置执行的方式是错误的：它应该是

和

，而不是分别是

和

，并且它们应该超出

您必须从

/

引用gwt maven插件，而不仅仅是

（它适用于maven编译器插件，因为它通过

war

隐式绑定到编译阶段；而jetty maven插件也可以，因为它将从命令行调用）

---

附带说明：将所有GWT依赖项（GWTServlet除外，但特别是GWT用户）放在提供的

中，以避免将它们捆绑到WAR中。另外，requestfactory apt是在编译时使用的，在运行时是无用的，所以也要使用提供的
；requestfactory server是gwt servlet的一个子集，所以您不需要两者兼而有之。

我强烈建议您将项目分为几个模块，一个模块用于GWT客户端代码，一个模块用于服务器端代码（第三个模块可能用于客户端和服务器之间共享的代码，例如GWT-RPC或RequestFactory接口，以及通过GWT-RPC传输的类）.
