无法写入：在属性文件中

Question

In my application user can change the propery file.. But that text contains : colon. While using obj.setProperty("key","value") it passes \\:

Please find the below example code and do needful.

String url="http://google.co.in";
Properties p=new Properties();
FileOutputStream o=new FileOutputStream("abc.properties");
p.setProperties("testurl",url);
p.store(o,null);
o.close();

Thank you Praveenkumar V

Answer 1

Refer the Properties class's store method API. It says the characters #, !, =, and : are saved with escaping backslash.

The key and element characters #, !, =, and : are written with a preceding backslash to ensure that they are properly loaded.

If you read the saved file back with load method in Properties class, there is no problem. If not, you'll have to write your own custom code to escape these characters while loading.

Answer 2

That's the normal behavior of the class. Read the javadocs for that: Properties

It says:

Characters that cannot be directly represented in this encoding can be written using Unicode escapes

The colon is one of these characters.
