SSH讀取applicationContext.xml配置文件測試hibernate方法

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

使用ClassPathXmlApplicationContext類！

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

而ClassPathXmlApplicationContext這個類他最終會在WEB-INF/classes/目錄下尋找，你項目最終部署後src下的東西都會部署在WEB-INF/classes/目錄下，所以木找到！

使用ClassPathXmlApplicationContext這樣讀取：則出現以下異常，找不到指定文件神馬的！

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 (系統找不到指定的路徑。)

沒辦法，就是讀不到，你寫絕得路徑都沒用！

好吧，讀取文件所在的絕對路徑吧，使用FileSystemXmlApplicationContext類！

 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());
 			
		}

	}
