Java 读取 .properties 配置文件的几种方式

 @Test
    void get_properties() throws IOException {
        //config为属性文件名，放在包com.test.config下，如果是放在src下，直接用config即可
        ResourceBundle resource = ResourceBundle.getBundle("xml/myconfig");
        String key = resource.getString("flag");
        System.out.println(key);
    }
