我一直在试图获得一个简单的spring mvc webapp工作。我或多或少地遵循本教程:http://www.codejava.net/frameworks/spring/spring-mvc-beginner-tutorial-with-spring-tool-suite-ideSpring调度程序servlet找不到index.html。在DispatcherServlet中找不到使用URI []的HTTP请求的映射
请注意,即时通讯使用弹簧3.2.5.RELEASE。除非控制器返回“index”,否则一切都工作正常,调度程序servlet映射到“/websitebasetest/WEB-INF/views/index.html”,即使在“WEB- INF /意见”。
控制器被称为是伟大的!但之后,似乎有一个问题发现相关的视图很奇怪,因为日志建议视图解析器在“/websitebasetest/WEB-INF/views/index.html”(见下文)中找到适当的视图。
我的问题是,为什么它没有找到视图(而是显示404),我如何得到它的工作?
以下是你可能会问的信息:

这没有奏效。事实上,当我尝试这个“Hello World”不会出现在控制台日志中。这意味着HomeController.index()没有被调用... – TenaciousDan
你可以共享一些控制台日志吗?我只是在本地进行了测试,并且工作正常。\ – Sohil
@TenaciousDan我在码头服务器上运行的其他修改是失去了所有slf4j依赖关系,并且失去了常见的日志记录排除功能。看看它是否适用于您。 – Sohil
