Spring Boot default properties encoding change?
Apparently properties loaded by Spring Boot's ConfigFileApplicationListener
are encoded in ISO 8859-1 character encoding, which is by design and according to format specification.
On the other hand, the .yaml format supports UTF-8 out of the box. A simple extension change fixes the problem for me.

I am trying to find a way to set UTF-8 encoding for properties accessed via
@Value
annotation from application.property files in Spring boot. So far I have been successfully set encoding to my own properties sources by creating a bean:@Bean @Primary public PropertySourcesPlaceholderConfigurer placeholderConfigurer(){ PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer(); configurer.setLocation(new ClassPathResource("app.properties"); configurer.setFileEncoding("UTF-8"); return configurer; }
Such solution presents two problems. For once, it does NOT work with "application.properties" locations used by default by Spring Boot (http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html#boot-features-external-config), and I am forced to use different file names.
And the other problem is, with it I am left with manually defining and ordering supported locations for multiple sources (eg. in jar vs outside jar properties file, etc) thus redoing a job well done already.
How would I obtain a reference to already configured PropertySourcesPlaceholderConfigurer and change it's file encoding at just the right time of application initialization?
Edit: Perhaps I am doing a mistake somewhere else? This is what causes actual problem for me: When I use application.properties to allow users to apply personal name to emails sent from an application:
@Value("${mail.mailerAddress}") private String mailerAddress; @Value("${mail.mailerName}") private String mailerName; // Actual property is Święty Mikołaj private InternetAddress getSender(){ InternetAddress sender = new InternetAddress(); sender.setAddress(mailerAddress); try { sender.setPersonal(mailerName, "UTF-8"); // Result is ÅšwiÄ™ty MikoÅ‚aj // OR: sender.setPersonal(mailerName); // Result is ??wiÄ?ty Miko??aj } catch (UnsupportedEncodingException e) { logger.error("Unsupported encoding used in sender name", e); } return sender; }
When I have
placeholderConfigurer
bean as shown above added, and place my property inside 'app.properties' it is resoved just fine. Just renaming the file to 'application.properties' breaks it. -
