我是 Spring MVC 的新手，还有另一个问题。当我启动我的应用程序时，我现在收到一条 HTTP 状态 404 消息，并且以下内容出现在我的控制台中：

尝试删除<servlet-class>标签中的空格，一些应用服务器对这种类型的东西很挑剔。我知道由于空格而导致 Spring XML 配置出现问题，通常是在我使用 Eclipse 格式化 XML 文件之后。

<servlet>
    <servlet-name>jcbulboard</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet><!-- This is line 13 -->

通过从我的 Tomcat jar 中删除 catalina.jar 解决了问题。

我对 Spring Boot 有同样的问题，添加这个依赖项修复了它：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>
