没有在tomcat中部署web.xml的Spring MVC应用程序给出404错误
我在Spring MVC中开发了一个应用程序，当我通过Run as - ＆gt;直接从eclipse运行它时工作正常。在服务器上运行。
但是现在我想将war部署到Tomcat文件夹并从那里运行它。我已经做了更改，战争正在部署到所需的tomcat文件夹但是当我启动tomcat服务器并在浏览器中访问应用程序URL时，它给了我404错误。服务器正在启动，没有任何例外。
以下是项目结构和文件：

1 个答案:
答案 0 :(得分：1)
在测试代码之后，我注意到你获得404的原因是因为你的应用程序由于找不到sql和properties文件而无法正确启动。
在您的代码中，sql和properties文件与java代码一起放置。当maven编译java代码时，会忽略sql和属性文件，因为它们不是java文件。因此，他们没有进入类文件夹，结果。您无法在运行时访问它们。
在maven中，有三个主要文件夹。的src / main / java中。 src / main / resources，src / test / java。 java代码应该转到第一个，测试应该转到最后一个，资源应该转到第二个。因此，您的属性，sql文件应放在src / main / resource文件夹中。在编译期间，src / main / resource文件夹中的所有内容都将放入WEB-INF / classes /文件夹中。因此，您将在以下路径中访问它们：classpath：xxxx.properties。
