Spring mvc Spring3MVC——HTTP 500错误，NoClassDefFoundException

当我在控制台中启动Spring3.2MVC应用程序时，出现了一个HTTP500错误，错误如下。我正在使用Tomcat 7.0.29

我在ghs1986-servlet.xml中有这个映射

<mvc:view-controller path="/" view-name="home" />

通过将tomcat-util.jar添加到我的类路径和WEB-INF/lib中，问题得以解决。tomcat-util.jar包含org.apache.tomcat.util.scan.JarFactory。

我认为这不可能是Spring错误。看来Tomcat有麻烦了。您是否检查了类路径中是否有双罐子或缺少罐子？看看这个：

@RequestMapping(value = {"/", "home"})
public String home() {
    return "home";
}
