SSH读取applicationContext.xml配置文件测试hibernate方法

如果你的applicationContext.xml文件是放在WEB-INF下：

使用ClassPathXmlApplicationContext类！

ApplicationContext context = new ClassPathXmlApplicationContext("/WEB-INF/applicationContext.xml");

而ClassPathXmlApplicationContext这个类他最终会在WEB-INF/classes/目录下寻找，你项目最终部署后src下的东西都会部署在WEB-INF/classes/目录下，所以木找到！

使用ClassPathXmlApplicationContext这样读取：则出现以下异常，找不到指定文件神马的！

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from file [E:\mycodes\shop2\WEB-INF\applicationContext.xml]; nested exception is java.io.FileNotFoundException: WEB-INF\applicationContext.xml (系统找不到指定的路径。)

没办法，就是读不到，你写绝得路径都没用！

好吧，读取文件所在的绝对路径吧，使用FileSystemXmlApplicationContext类！

 ApplicationContext context=new FileSystemXmlApplicationContext("E:\\mycodes\\shop2\\WebRoot\\WEB-INF\\applicationContext.xml");

-----------------------------------------------------------------------------------------------------

	public static void main(String[] args) {
		
	 ApplicationContext context=new FileSystemXmlApplicationContext("E:\\mycodes\\shop2\\WebRoot\\WEB-INF\\applicationContext.xml");
	 
	 ProductDAO dao =(ProductDAO) context.getBean("ProductDAO");
	 
	 List<Product> list =dao.findAll();
		
		for (Product product : list) {
			
			System.out.println(product);
			
			System.out.println(product.getCode());
 			
		}

	}
