两行代码轻便搞定XML和对象间相互转换. XStream 简单示例

两行代码轻松搞定XML和对象间相互转换. XStream 简单示例.

很方便,很容易,很快,心情很愉快:)

对象转String,String转对象.对象转文件,文件转对象.

 

 /**
	 * 对象转文件,文件转回对象
	 */
	@Test
	public void testFromFile() throws IOException {

		String fileName = "d:/personBObj.xml";
		OutputStream out = null;
		InputStream input = null;
		File file = new File(fileName);
		XStream xstream = initXStream();
		PersonBObj personBObj = personBObjInit();

		try {
			// 对象生成XML文件
			out = new FileOutputStream(fileName);
			xstream.toXML(personBObj, out);
			Assert.assertTrue(file.exists());

			// XML文件转对象
			input = new FileInputStream(fileName);
			PersonBObj fromFileBObj = (PersonBObj) xstream.fromXML(input);
			Assert.assertEquals("1", fromFileBObj.getContId());

		} finally {
			out.close();
			input.close();
		}

		if (file.exists()) {
			file.delete();
		}
	}
