    </beans>

我只是想在页面中打印消息，我是否需要applicationContext.xml文件？如果是，我如何在项目中添加它？我读到spring搜索[servlet-name] -servlet.xml文件。

Answer 1

您必须在 web.xml 文件中初始化 dispatcher-servlet.xml 文件。更改您的web.xml文件，添加这些行。

<init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
</init-param>

这是您最后的web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>SpringMVCTest</display-name>
  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

  <servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>
                   org.springframework.web.servlet.DispatcherServlet
            </servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
    </init-param>
</servlet>

  <servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

您应该在 WEB-INF 文件夹下创建dispatcher-servlet.xml文件
