尝试下一个：
ClassLoader classloader = Thread.currentThread().getContextClassLoader();
InputStream is = classloader.getResourceAsStream("test.csv");
如果上述方法不起作用，则已在以下类中添加了各种项目：1（代码在此处）。2ClassLoaderUtil
以下是有关如何使用该类的一些示例：
src \ main \ java \ com \ company \ test \ YourCallingClass.java
src \ main \ java \ com \ opensymphony \ xwork2 \ util \ ClassLoaderUtil.java
src \ main \ resources \ test.csv
// java.net.URL
URL url = ClassLoaderUtil.getResource("test.csv", YourCallingClass.class);
Path path = Paths.get(url.toURI());
List<String> lines = Files.readAllLines(path, StandardCharsets.UTF_8);
// java.io.InputStream
InputStream inputStream = ClassLoaderUtil.getResourceAsStream("test.csv", YourCallingClass.class);
InputStreamReader streamReader = new InputStreamReader(inputStream, StandardCharsets.UTF_8);
BufferedReader reader = new BufferedReader(streamReader);
for (String line; (line = reader.readLine()) != null;) {
// Process line
}
