配置SpringMVC時出現Tomcat無法啟動，SpringMVC的jar包

今天在配置SpringMVC時，不知道是何原因Tomcat無法啟動了，而刪除SpringMVC項目后，tomcat又正常了，但一直提示信息: No Spring WebApplicationInitializer types detected on classpath。

目前還不知打哦是什么原因造成，可能跟tomcat版本為7過高有關，而我用的Spring版本可能不合適。我會后續改進，改好后會寫出解決方案。如果有知道為什么的可以留言評論，謝謝大家。

<!--下面為改好的方案-->詳細的配置SpringMVC過程可以看我的配置SpringMVC的博客。

首先我們分析下，tomcat是在我配置SpringMVC的過程中導致tomcat無法啟動的，而在這其中，我們修改的僅僅是所配項目的wub.xml發生了改變，而錯誤信息顯示我們配置的項目在tomcat上發布了，但發布的項目中web.xml配置錯誤。我們要找到web.xml中的錯誤，其中最為簡單是由於<url-pattern>的錯誤，由於/的存在。

另外要看好自己的classpath，有的默認classpath為web項目下的src，有的為WebContent下的Web-INF。

個人建議將Spring、hibernate等涉及Web的jar包放在Web-INF下的lib文件夾中，因為tomcat運行尋找jar包首先會看此位置的jar包，一些明明添加build path的jar包也許運行時仍提示找不到Class，也就是因為放在java Libraries下，而不是放在Web_INF下的lib中。

相關錯誤信息為：

信息: validateJarFile(E:\project\boce\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\SpringMvcTest\WEB-INF\lib\servlet-api.jar) - jar not loaded. See Servlet Spec 3.0, section 10.7.2. Offending class: javax/servlet/Servlet.class

分析上面的錯誤信息是由於在配置文件web.xml中出現的/*.do出現的問題。這個問題可以通過將/去掉來解決。這是關於配置時最簡單的錯誤。

 <servlet>  
        <servlet-name>springmvc</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
    <servlet-mapping>  
        <servlet-name>springmvc</servlet-name>  
        <url-pattern>/*.do</url-pattern>  
    </servlet-mapping> 

改為：

 <servlet>  
        <servlet-name>springmvc</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
    <servlet-mapping>  
        <servlet-name>springmvc</servlet-name>  
        <url-pattern>*.do</url-pattern>  
    </servlet-mapping>

現對上述問題作出我個人的解決，如果有相似情況可以進行嘗試。

相似情況無法啟動時，有時候會報少包多包等錯誤，再此為了避免在配置SpringMVC過程中出現這種來回下載來回找Jar包的問題，給各位提供一個全面的針對SpringMVC框架的jar包。（本文所引用的jar包來自互聯網，包括Spring的相關jar包，hobernate相關jar包，以及mysql數據庫連接jar包）

下面是jar包詳細目錄：

下面是百度網盤分享SpringJar的文件，有需要進行SpringMVC架構的初學者可以使用。（因為初學者不知道該使用哪些jar包，自己很難調配）
