Is there any way to achieve this?

presently I have configured all properties

Answer 1

Create customized PropertyPlaceHolderConfigurer extending Spring PropertyPlaceHolderConfigurer

public class PropertyPlaceholderConfigurer extends
        org.springframework.beans.factory.config.PropertyPlaceholderConfigurer {

    @Override
    protected String convertPropertyValue(final String originalValue) {
        if (originalValue.startwith("SomeText:")) {
            //Apply the decryption logic
            ...
        }
    }
}

You can encrypt the properties and append SomeText:. Use this customized PropertyPlaceHolderConfigurer to load the properties
