```java
// 读取路径
File file = new File(KeyWordExtract.class.getResource("/").getPath() + classpath);
if (file.exists()) {
    return Files.readAllLines(file.toPath());
}
// 高效的类加载器方式获取文件
InputStream in = Thread.currentThread().getContextClassLoader().getResourceAsStream(classpath);
BufferedReader buffer = new BufferedReader(new InputStreamReader(in));
return buffer.lines().collect(Collectors.toList());
```
