JAVA本地程序使用FileSystemXmlApplicationContext读取applicationdatasorce.xml进行数据库操作

使用绝对路径读取,就绝对不会出错

程序代码如下,这个类是BookDaoTest

　　　　　　　String appContextPath = BookDaoTest.class.getClassLoader().getResource("").getPath() + "../";
            File file = new File(appContextPath);
            String abPath = null;
            try {
                abPath = file.getCanonicalPath();
            } catch (IOException e) {
                e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
            }
            String[] ctxConfig = {"file:" + abPath + "/applicationContext-beans.xml", "file:" + abPath + "/applicationContext-datasource.xml", "file:" + abPath + "/applicationContext-security.xml"};
            ApplicationContext context = new FileSystemXmlApplicationContext(ctxConfig);

            BookDao bookDao = (BookDao) context.getBean("bookDao");
