Could not read properties if it contains dollar symbol (${var})

Question

I have property file with following content:

INVALID_ARGUMENT=Field ${fieldName} is invalid or missing.

I read this using spring configuration:

@PropertySource("error_messages_en.properties")
@Configuration
public static class ErrorMessagesEn {
     @Value("${INVALID_ARGUMENT}")
    private String invalidArgument;
}

But after application start I see:

Could not resolve placeholder 'fieldName' in value "Ïîëå ${fieldName} íåêîððåêòíî çàïîëíåíî èëè ïðîïóùåíî."

I need ${fieldName} because I want to use repacer: https://stackoverflow.com/a/3655963/2674303

How to avoid this error?

Is not clear to me where you change the placeholder. I think you miss to explain this part. — Mario Santini, Apr 19 '17 at 11:05

I want to read value to string with content **Field ${fieldName} is invalid or missing.** and then replace **${fieldName}** with value from runtime — gstackoverflow, Apr 19 '17 at 11:11

You should escape ${fieldName} as it is not defined as a Spring property.

You could have a look at this question: Escape property reference in spring property file and the associated answer.

You should write this instead:

INVALID_ARGUMENT=Field #{'$'}{fieldName} is invalid or missing.

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'INVALID_ARGUMENT' in value "${INVALID_ARGUMENT}" – gstackoverflow Apr 19 '17 at 11:21
I have tested and I do not produce this issue. Are you sure it is linked? If you set `INVALID_ARGUMENT=foo` are you getting the issue too? – Nicolas Labrot Apr 19 '17 at 11:38
looks like encoding issue, but I am not sure – gstackoverflow Apr 19 '17 at 12:13

If you are using a yaml file you need to surround the value with quotes

argument: "Field #{'$'}{fieldName} is invalid or missing."
