org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [applicationContext.xml]; nested exception is java.io.FileNotFoundException: class path resource [applicationContext.xml] cannot be opened because it does not exist

想在本地启动Spring,然后从框架中获得一个bean,于是就有了下面的故事,对于一个程序猿来说这样的异常是不能容忍的,为什么?因为特么介个异常是异常界的屌丝,一个词:低级!忠告:不过,你最好表这样子!千万不要瞧不起!

此异常问题很明显,就是在classpath下找不到applicationContext.xml文件。

下面我们就来看一下,几种加载方式,以及路径说明:

private static String path = "D:\\workspaceSpark\\src\\main\\resources\\applicationContext.xml";
private static String classpath = "applicationContext.xml";

//通过XmlBeanFactory获取bean,通过ClassPathResource类加载applicationContext,从类名知道applicationContext.xml必须位于classpath下
XmlBeanFactory factory = new XmlBeanFactory(new ClassPathResource(classpath));
ConnectionManager connectionManager = (ConnectionManager) factory.getBean("connectionManager");

//通过ApplicationContext上下文获取bean,通过FileSystemXmlApplicationContext类加载applicationContext,可同时加载多个xml文件,从类名知道只要路劲正确就可以将applicationContext.xml加载
ApplicationContext context =
        new FileSystemXmlApplicationContext(new String[] {path});
ConnectionManager connectionManager = (ConnectionManager) context.getBean("connectionManager");

//通过ApplicationContext上下文获取bean,通过ClassPathXmlApplicationContext类加载applicationContext,可同时加载多个xml文件,从类名知道applicationContext.xml必须位于classpath下
ApplicationContext context =
        new ClassPathXmlApplicationContext("applicationContext.xml");
ConnectionManager connectionManager = (ConnectionManager) context.getBean("connectionManager");

注:很多人总搞不清楚classpath到底是哪里,Java Project项目其实就是指的src目录,如果是maven项目就是指的resources
