SSM整合项目Bug&Debug记录_17:34:45,840 debug antpathrequestmatcher:157

本文记录了在SSM整合项目中遇到的Bug，包括登录页面匹配失败的问题，原因是login.jsp和failer.jsp放置位置不正确，应置于webapp根目录下，而非webapp/pages。另外，还提及了SpringMVC配置路径错误导致无法找到applicationContext.xml配置文件，解决办法是检查web.xml中配置的路径拼写。

Bug: .matcher.AntPathRequestMatcher - Checking match of request : ‘/login.jsp’; against ‘/login.jsp’

Debug login.jsp文件和failer.jsp文件位置放错了，应该直接放在webapp目录下，而不是放在webapp/pages文件夹下。

Bug:

Type Exception Report

Message Servlet.init() for servlet [springmvc] threw exception

Debug：
一般都是springmvc的配置路径不对导致找不到applicationContext.xml配置文件
在web.xml中，查看路径拼写是否正确，我当时的错误是由于Location单词出错

<servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
    </servlet>
