Spring读取配置文件的几种方式

// 加载配置文件
ClassPathResource classPathResource = new ClassPathResource("template/books.xml");
InputStream inputStream =classPathResource.getInputStream();

// 加载配置文件
InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("template/books.xml");

InputStream inputStream = this.getClass().getResourceAsStream("template/books.xml");

File file = ResourceUtils.getFile("classpath:template/books.xml");
InputStream inputStream = new FileInputStream(file);

File directory = new File("src/main/resources");
String courseFile = directory.getCanonicalPath();//这种方式也能获取到一样的结果

// 获得路径在target下
String path = BookController.class.getClass().getResource("/com/scba/modules/book/books.xml").getPath();
// 获得路径在源码src下
String path = ResourceUtils.getFile("src/main/java/com/scba/modules/book/books.xml").getAbsolutePath();
