可以看出错误：java.lang.IllegalStateException: Failed to load ApplicationContext
1、解决方法：
主方法加上@ContextConfiguration(locations = {“classpath*:spring/spring.xml”,”classpath*:spring/spring-mybatis.xml”})

(1).spring.xml文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans"    xmlns:context="http://www.springframework.org/schema/context"    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       ">    <!-- spring执行顺序，导致部分先执行的容器没有注入bean，使用该配置，先扫描在进行注入 -->    <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />    <!-- 引入属性文件 -->    <context:property-placeholder location="classpath:config.properties" />    <!-- 扫描包com.vision.edu.dao,com.vision.edu.service 注解为Service和Repository的类 -->    <context:component-scan base-package="com.ssm.pengcheng.mapper,com.ssm.pengcheng.service">        <context:include-filter type="annotation" expression="org.springframework.stereotype.Service" />        <context:include-filter type="annotation" expression="org.springframework.stereotype.Repository" />    </context:component-scan>    <!-- <import resource="classpath:spring/spring-mybatis.xml" /> --></beans>
