Spring无法获取ApplicationContext上下文对象怎么解决？

涉及到的类包括：
1. ITestService.java
2. TestServiceImp.java
3. autoWiringService.java
以及Spring配置文件：
4.autoWiring.xml

对应的源码为：
1. ITestService.java

 package com.z.test.annotation;

/**
 * Created by Z on 2016/11/16.
 */
public interface ITestService {
    public void annoTest();
}

2.TestServiceImp.java

 package com.z.test.annotation;
import org.springframework.stereotype.Service;

/**
 * Created by Z on 2016/11/16.
 * 如何引入注解
 */
@Service("testServiceImp")
public class TestServiceImp implements ITestService {
    public void annoTest(){
        System.out.println("注解调用");
    }
}

3.autoWiringService.java

 package com.z.test.annotation;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import javax.annotation.Resource;

/**
 * Created by Z on 2016/11/16.
 */
public class AutoWiringService {

    @Resource(name ="testServiceImp")
    public  ITestService iTestService;

    public void autoTest(){
        iTestService.annoTest();
    }


    public static void main(String[] args){

        ApplicationContext context =new ClassPathXmlApplicationContext("autowiring.xml");
        AutoWiringService autoW=(AutoWiringService)context.getBean("autoWiringService");
        autoW.autoTest();

    }
}

使用了@Service 和 @Resource注解。目录结构：

在AutoWiringService运行主方法进行测试时，总是有错误如下：

猜测是否是无法读取xml文件？还是哪里没有配置好？

autoWiring.xml文件是这样配置的：

 <?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:cotent="http://www.springframework.org/schema/cache"
       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/cache http://www.springframework.org/schema/cache/spring-cache.xsd http://www.springframework.org/schema/context
        ">
    <!--Bean的自动装配-->
    <!--<bean id="autoWiringDAO" class="com.z.autowiring.AutoWiringDAO" />-->

    <bean id="autoWiringService" class="com.z.test.annotation.AutoWiringService" />

    <!-- 扫描 哪些包或者类 需要用到注解 -->
    <context:component-scan base-package="com.z.test.annotation" />
    <!-- 使用注解 -->
    <cotent:annotation-driven/>

</beans>

你在web.xml中配置了吗，检查一下，那边很重要

spring的配置文件是什么样的呢，有没有配置注解扫描的包？
