当我试图运行这个简单的HTML表单：HTTP状态500 - 为servlet调度Servlet.init（）抛出异常
<html>
<head>
<title>Enter a new Page</title>
</head>
<body>
<div id="editPresPage">
<form action="editPresPage.do" method="post">
<label>Enter Page ID</label><input type="text" name="page_id"/>
<label>Enter Header1</label><input type="text" name="h1"/>
<label>Enter Header2</label><input type="text" name="h2"/>
<label>Enter Header3</label><input type="text" name="h3"/>
<label>Enter Header4</label><input type="text" name="h4"/>
<label>Enter Page Text</label><input type="text" name="page_text"/>
<input type="submit" value="Add New Page"/>
</form>
</div>
</body>
</html>
，我发现了错误HTTP状态500 - Servlet.init（ ）servlet Dispatcher在我的浏览器中抛出异常。
在我的命令行窗口（这当我运行tomcat的start.batch文件打开） ，我发现了以下错误：
的log4j：警告没有附加目的地可以发现记录器（ORG。 springframework.web.servlet.dispatcherservlet）
那我的调度员-servlet.xml文件：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<import resource="/application.xml"/>
<bean name="/editPresPage.do"
class="my.pack.webTier.control.EditPresPageController" >
<property name="page_manager_service" ref="page_manager_service"/>
</bean>
<!-- I also tried using with annotations -->
<!-- <context:component-scan base-package="my.pack"/> -->
</beans>
这是我的web.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

version="2.5">

<servlet-name>Dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Dispatcher</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<!-- Tomcat configuration -->
<Context path="/myWebApp" docBase="../tomcat\work\Catalina\localhost\mywebapptomcat\work\Catalina\localhost\mywebapp">
<Loader
loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>
</Context>
</web-app>
而这就是我的控制器：
package my.pack.webTier.control;
import my.pack.dataAccessTier.domain.Presentation_page;
import my.pack.serviceTier.services.Page_manager_service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
//@Controller
public class EditPresPageController {
//@Autowired
private Page_manager_service page_manager_service;
public void setPage_manager_service(Page_manager_service page_manager_service) {
this.page_manager_service = page_manager_service;
}
@RequestMapping("/editPresPage")
public ModelAndView EditPresPage(@RequestParam("page_id") int page_id,
@RequestParam("h1") String h1_value,
@RequestParam("h2") String h2_value,
@RequestParam("h3") String h3_value,
@RequestParam("h4") String h4_value,
@RequestParam("page_text") String page_text)
{
Presentation_page new_page=new Presentation_page(page_id,h1_value,h2_value,
h3_value,h4_value,page_text);
page_manager_service.create_new_page(new_page);
return new ModelAndView("/thanks.html");
}
}
那堆栈跟踪：

我和春天MVC 3.2工作，日食3.7，springTomcat/7.0.30和在我的项目中使用ANT。
我已经搜索了这个要求的答案 - 并没有找到一个。
我认为你的web.xml中缺少 -Tag。 –
