我正在尝试设置一个Spring MVC项目。我添加了一个调度程序servlet，一个jsp并设置了web.xml文件。但我不断
WARN org.springframework.web.servlet.PageNotFound-在DispatcherServlet中，名称为“ HelloWeb”的URI [/safesite/WEB-INF/jsp/hello.jsp]的HTTP请求未找到映射
这是我的web.xml

我的HelloController
package org.activiti.explorer.controller;

return new ModelAndView("hello", "message", message);

}
而我的hello.jsp

<%@page trimDirectiveWhitespaces="true" %>
<!DOCTYPE html>

<body>
我无法弄清楚这一点，因此将不胜感激。
最佳答案
您似乎缺少了<mvc:annotation-driven />
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- Enables the Spring MVC @Controller programming model -->
<mvc:annotation-driven />
<context:component-scan base-package="org.activiti.explorer.controller" />
<bean id="viewResolver"
class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass"

<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
请注意，我已经从xsd文件中删除了该版本，这意味着它将使用您jar文件中的模式（如果不兼容，将会出现验证错误）
@Nikolay发表评论后，我还注意到您的映射中存在错误（请注意，您仍然需要注释驱动的元素），您应该将控制器中的映射更改为
@RequestMapping("/hello.jsp")
并通过访问
/safesite/hello.jsp
或者，更常见的是，将servlet映射更改为
<servlet-mapping>
<servlet-name>HelloWeb</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
并按照尼古拉所说的方式访问
/safesite/hello
