java更新属性文件运行时 [英] java update properties file run time

问题描述

我正在为生产监控编写独立的Java应用程序。一旦开始运行，api就会配置为在.properties文件中设置的默认值。在运行状态下，可以更改api的配置，并相应地更新.properties文件。有没有办法实现这个目标？或者有没有其他方法来实现这个？

i am writing standalone java app for production monitoring. once it starts running the api is configured for default values which is set in .properties file. in running state the api's configuration can be changed and the .properties file should be updated accordingly. is there a way to achieve this ? or are there any other approaches to implement this ?

推荐答案

Java Properties类（ api here ）指定load和store方法，它们应该完全相同。使用FileInputStream和FileOutputStream指定要将其保存到的文件。

The Java Properties class (api here) specifies "load" and "store" methods which should do exactly that. Use FileInputStream and FileOutputStream to specify the file to save it into.
