Spring简单例子开发 求大牛解答！
我按照例子在eclipse下写了一个很简单的spring页面，可是为毛tomcat一直显示404呢。
ps，我的Book.java，BookController.java都是放在包Test_1_Bookstore_3下面，
其余所有的.xml和jsp直接放在WEB-INF下面。

我的web.xml如下
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  <display-name>Test_1_Bookstore_3</display-name>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <servlet>
   <servlet-name>viewspace</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
   <servlet-name>viewspace</servlet-name>
   <url-pattern>*.html</url-pattern>
  </servlet-mapping>
  
  
  <welcome-file-list>
    <welcome-file>Book.jsp</welcome-file>
  </welcome-file-list>
</web-app>


ApplicationContext.xml如下：（其实是空的 里面没定义什么内容）
<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
 xsi:schemaLocation="http://www.springframework.org/schema/beans  
 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">  
</beans>


定义的viewspace-servlet如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
