properties文件
什么是properties文件:
后缀为properties文件,是一种属性文件。
文件信息存储特点
以<key,value>格式存储内容。
文件读取
Java中使用Properties类读取这类文件。
文件作用
往往程序中有很多信息,与程序本身无关,但是运行时候需要用到这些信息,因此就起个名字独立出来,待用时,程序通过代码把信息进行加载。由于加载的信息都是引用,因此日后想改变其中一个参数,只需在文件中改动相关信息就可。(便于代码重构,方便维护)
文件内容注释
properties文件中增加或者取消#注释,可以通过 Ctrl + / 实现。
可选中一行或多行内容进行操作,即可实现单行或多行内容的注释或取消注释。
