Set empty string as the value of a key in properties file
提问by Susie
jdbc.password=
How can I assign jdbc.passwordkey in my application.properties file an empty string?
如何jdbc.password在我的 application.properties 文件中指定一个空字符串？
I understand I can do this programmatically as follows, but I would like to set this in properties file.
我知道我可以按如下方式以编程方式执行此操作，但我想在属性文件中进行设置。
Properties props = new Properties();
props.put("password", "");

Just leaving the value empty on the RHS should be fine:
只需将 RHS 上的值留空就可以了：
password=
Sample code:
示例代码：
import java.io.*;
import java.util.*;
class Test{
public static void main(String [] args) throws Exception {
Properties props = new Properties();
props.load(new StringReader("password="));
System.out.println(props.size()); // 1
System.out.println(props.getProperty("password").length()); // 0
}
}
