我已经安装了 STS 3.0.1，并且正在关注我的书 Pro Spring MVC with Web Flow（来自 APress）。

我已将书籍/出版商提供的源代码导入 STS。我添加了 Tomcat7 服务器并选择了 Tomcat7 作为 Targeted Runtime。

我已将 Tomcat7 设置为使用 JDK 1.6。根据我的配置，STS 似乎也在使用 JDK 1.6。

我可以使用 Gradle 构建我的项目，将 war 文件移动到 webapps 文件夹，手动重新启动 Tomcat7（在 Eclipse 之外），它就会工作。

但是，从 STS 本身，当我选择 Run as -> Run on server 时，我收到以下错误：

问题是这个

ServletContext 类型的方法 addServlet(String, DispatcherServlet) 未定义

如果您检查 javadoc 可以看到 addServlet 方法在 JavaEE5 中不存在

http://docs.oracle.com/javaee/6/api/javax/servlet/ServletContext.html http://docs.oracle.com/javaee/5/api/javax/servlet/ServletContext.html

这意味着您的 Tomcat7 尝试使用 Tomcat6 配置。在eclipse中打开server选项卡，双击tomcat 7安装。然后检查运行时下拉菜单是否设置为 Tomcat7。此外，您可以单击“打开启动配置”并查看库是否设置正确。如果这些都没有帮助，您可以尝试从 eclipse 中删除您的 tomcat 实例并尝试创建一个新实例。

我无法解释为什么，但我切换到 STS 3.1.0 而不是 Groovy/Grails Suite 3.1.0（不知道为什么一开始就使用它）。

现在，到目前为止，我所获得的教程和解释都有效。哇！
