xml配置的问题会引起各种组合错误，少一项就会错。

Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/applicationContext.xml]

这种错误的时候可能就是因为少了

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/spring/spring-sevlet.xml</param-value>
</context-param>

，因为我把它注释掉了，就会出现以上错误。

org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from ServletContext resource [/WEB-INF/springmvc-servlet.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/springmvc-servlet.xml]

出现这种错误可能就是因为找不到spring-sevlet.xml配置，因为会默认去resources文件夹下面去找

<servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--<init-param>-->
        <!--<param-name>contextConfigLocation</param-name>-->
        <!--<param-value>WEB-INF/spring/spring-sevlet.xml</param-value>-->
    <!--</init-param>-->
    <load-on-startup>1</load-on-startup>
</servlet>

由于我把init-param注释掉了，只能去默认路径下面去找了。现在我将它放开以后，就能在init的时候指定配置文件路径

spring-sevlet全部配置如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/spring/spring-sevlet.xml</param-value>
</context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>WEB-INF/spring/spring-sevlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

比较疑惑的是，我context-parm也指定过了，还需要在servlet的init-param里面去指定。
