ssm项目中springmvc报Context initialization failed错误
今天自己搭了一个ssm的项目，启动tomcat的时候报了Context initialization failed（上下文初始化失败），错误信息如下：

omitted刚开始我以为web.xml中的配置springmvc的控制器写错了，就赶紧去检查了一遍，看看标签的名字是否和springmvc.xml文件名是否一致，经检查是保持一致，又看了下导入的包名和其他的一些配置，没有发现错误。于是就去看了下springmvc.xml文件，也没有发现错误。以下是springmvc.xml中的信息：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!--自动扫描注解--> <context:component-scan base-package="com.lyb.controller"></context:component-scan> <!--开启Aspects生成代理对象--> <aop:aspectj-autoproxy /> <!--配置springmvc的注解驱动--> <mvc:annotation-driven /> <!--配置springmvc的制图解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property> <property name="prefix" value="/"/> <property name="suffix" value=".jsp"/> </bean> <!--文件上传的视图解析器--> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!--文件的最大上传大小，单位为字节，此处设置为100M--> <property name="maxUploadSize" value="104857600"></property> </bean> <!--配置拦截器--> <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/**"/> <bean class="com.lyb.interceptor.MyInterceptor"></bean> </mvc:interceptor> </mvc:interceptors> <!-- 异常处理器 --> <bean id="handlerExceptionResolver" class="com.lyb.exception.CustomExceptionResolver"/> </beans>于是我就想着先来简单的配置一下springmvc，先把可以省略的配置先注释掉，当我把配置拦截器注释掉的时候，发现竟然不报错了，原来我只是简单写了一个拦截器，而没有实现HandlerInterceptor接口。之前只是想着先配出来，让springmvc.xml文件不报错。 这次错误也让我明白了不需要什么功能的时候，先别配置相关功能的，等需要的时候在配置也不迟。 以上只是个人遇见的问题，本人也是新手一枚，若有不足或错误，还请指出，我也会虚心接受，学习。
