反射获取application.properties内容

public class ABCD{

private String HDFS_HOST;
private String FILE_LOCAL;
private String HDFS_USER;
private String HDFS_FILE_PATH;

{
    Properties properties = new Properties();
    ClassLoader classLoader = ABCD.class.getClassLoader();
    InputStream inputStream = classLoader.getResourceAsStream("./application.properties");
    try {
        properties.load(inputStream);
    } catch (IOException e) {
        e.printStackTrace();
    }
    HDFS_HOST = properties.getProperty("file.hdfs.host");
    FILE_LOCAL = properties.getProperty("file.local");
    HDFS_USER = properties.getProperty("hdfs.user");
    HDFS_FILE_PATH = properties.getProperty("hdfs.file.path");
}

}

以下为application.properties 文件内容
