注意xml头部问题
比如在xx-servlet中注意:

    <mvc:annotation-driven/>    <context:component-scan base-package="cn.itcast.ssm.controller"></context:component-scan>

要用

<beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"       xmlns:context="http://www.springframework.org/schema/context"       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"       xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.2.xsd        http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd        http://www.springframework.org/schema/tx        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

注意是否拦截了url
扫描时抛异常

原因:java8和spring3的结合会有很多诡异的BUG,切记
