Spring spring框架对配置文件找不到的处理

问题复述

在一次使用ssm开发的时候，发现了此bug

public class TestGetBeanProductTypeServiceImpl {

    /**
     *  用于测试：
     */
    @Test
    public void test() {
        ClassPathXmlApplicationContext classPathXmlApplicationContext = new ClassPathXmlApplicationContext("spring/application-*.xml");

        String[] beanDefinitionNames = classPathXmlApplicationContext.getBeanDefinitionNames();
        for (String beanDefinitionName : beanDefinitionNames) {
            System.out.println("beanDefinitionName = " + beanDefinitionName);
        }

        ProductTypeService productTypeServiceImpl = (ProductTypeService) classPathXmlApplicationContext.getBean("ProductTypeServiceImpl");

        List<ProductType> all = productTypeServiceImpl.getAll();
        all.forEach(type -> System.out.println(type.toString()));
    }

}

代码如上所示：

我的配置文件：

在获取productTypeServiceImpl的时候，第一次出现了异常

第一次出现之后，我认为是bean id的问题，定义了bean id之后，同样是此问题，后来对比了配置文件之后，发现问题所在

正确代码：

ClassPathXmlApplicationContext classPathXmlApplicationContext = new ClassPathXmlApplicationContext("spring/applicationContex-*.xml");

问题分析

debug展开对问题的分析：

配置文件错误应该报出的是FileNotFoundException异常，为什么会No bean name异常？

经过分析，在深入了spring的源码之后

在上下文环境配置的源码中org.springframework.context.support.AbstractApplicationContext

发现问题

此代码缺少对parent为空的处理，我认为此处应该报出一个FileNotFoundException异常， 而不是直接执行下一步。
