I am trying to create a web application using Spring Boot and Thymeleaf and am having trouble getting the template to use the messages defined in a properties file. Instead of the message defined in the properties file, it is instead showing ??form.welcome_en_GB?? The console isn't logging any errors.
The project structure is like this
──┬ 🗁 src
│ └─── 🗁 main
│ ├─── 🗁 java
│ │ └─── 🗁 com
│ │ └─── 🗁 package
│ │ ├─── 🗁 controller
│ │ │ └─── FormController.java
│ │ ├─── Application.java
│ │ └─── ServletInitializer.java
│ └─── 🗁 resources
│ ├─── 🗁 static
│ │ └─── home.html
│ ├─── 🗁 templates
│ │ ├─── form.html
│ │ └─── form.properties
│ └─── application.properties
└─── pom.xml
Application.java
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
ServletInitializer.java
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
FormController.java
@Controller
@RequestMapping("/form")
public class FormController {
private static final Logger log = LoggerFactory.getLogger(FormController.class);
@RequestMapping(value = "/new", method = RequestMethod.GET)
public ModelAndView getNewReportForm() {
log.info("New form requested");
ModelAndView mav = new ModelAndView("form");
return mav;
}
}
form.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
<head>
<title>Form</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<link rel="stylesheet" type="text/css" media="all"/>
</head>
<body>
<p th:text="#{form.welcome}">Welcome!</p>
</body>
</html>
form.properties
form.welcome=Hello there!

I believe that changing the name of form.properties to messages.properties and locating it in the root of your resources folder should allow spring boot to pick it up automagically.
When I have multiple message files I explicitly list them in a MessageSource bean so that the MVC auto-configuration picks them up, e.g.:
@Bean
public MessageSource messageSource() {
final ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setBasenames("classpath:/some-mvc-messages", "classpath:/some-other-mvc-messages", "classpath:/another-projects/mvc-messages");
messageSource.setUseCodeAsDefaultMessage(true);
messageSource.setDefaultEncoding("UTF-8");
messageSource.setCacheSeconds(5);
return messageSource;
}
I Have the same Issue while using messages.properties file The issue was @EnableAutoConfiguration not added in my Spring boot file
@SpringBootApplication
@EnableAutoConfiguration
public class Run {
public static void main(String[] args) {
SpringApplication.run(Run.class, args);
System.out.println("Run");
}
}
After added its work
