收到警告“[org.springframework.web.servlet.PageNotFound]（默认任务 1）GET /ProjectFE/ 没有映射”
getting an warning as" [org.springframework.web.servlet.PageNotFound] (default task-1) No mapping for GET /ProjectFE/"
正如标题所说，我遇到了一个错误
[org.springframework.web.servlet.PageNotFound] (default task-1) No mapping for GET /ProjectFE/ 我该如何解决这个问题？另外，代码没有错误。
这是我的代码：

项目结构：
首先把你的web.xml安排成这样
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<!-- Processes application requests -->
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
WEB-INF/spring-config.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
在定义 contex-param 时，您不需要使用 init-param 相同的 xml 文件。
现在在 spring-config.xml
中稍微改变一下
<?xml version="1.0" encoding="UTF-8"?>

<beans:property name="suffix" value=".jsp" />
</beans:bean>

</beans:beans>
仔细看<beans:property name="prefix" value="/Views/" />行。您的文件夹名称是 Views，但您定义了 view。这就是为什么您可能会收到错误的原因。
