Custom Messages in Bean Validation using Spring’s Validator interface
<p>I'm using Spring Boot 1.3.5 with Rest Controllers and everything is working fine.</p>

<p>I am also using Spring's validation sample techniques from the official documentation (JSR-303 Bean Validation API and Spring's validator interface, i tried both and faced the same problem) and the validations are working, but I am not able to configure custom messages.</p>

<p>I have configured a messages.properties file, and I can access the messages on this file just fine. However this validation seems not to be capable of reading or accessing my messages source (messages.properties) configured automatically via spring boot.</p>

<p>I can access the messages directly from the messages source object injected in controller via @Autowired (there's a comment in the code). However, the binding result of the Spring's validator interface or the JSR-303 Bean Validation seems to not be capable of accessing the messages.properties loaded in MessageSource. The result I have is that my errors have codes but don't have default messages.</p>

<p>Here is my Application class:</p>

<pre><code>@SpringBootApplication
@ImportResource({ "classpath:security/cas-context.xml", "classpath:security/cas-integration.xml",
    "classpath:security/security.xml" })
@EnableAutoConfiguration(exclude = VelocityAutoConfiguration.class) // http://stackoverflow.com/questions/32067759/spring-boot-starter-cache-velocity-is-missing

public class Application extends SpringBootServletInitializer {

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(Application.class);
}

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}

@Bean
public ServletRegistrationBean cxfServlet() {
    return new ServletRegistrationBean(new CXFServlet(), "/services/*");
}

@Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
    return new SpringBus();
}

@Bean
public Nfse nfseService() {
    return new NfseImpl();
}

@Bean
public Endpoint endpoint() {
    EndpointImpl endpoint = new EndpointImpl(springBus(), nfseService());
    endpoint.publish("/nfseSOAP");
    return endpoint;
}
</code></pre>

<p>}</p>

<p>Here is my Bean:</p>

<pre><code>public class Protocolo {

private Long id;

@NotNull
@Min(1)
@Max(1)
private String protocolo;

private StatusProtocoloEnum status;

public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public String getProtocolo() {
    return protocolo;
}

public void setProtocolo(String protocolo) {
    this.protocolo = protocolo;
}

public StatusProtocoloEnum getStatus() {
    return status;
}

public void setStatus(StatusProtocoloEnum status) {
    this.status = status;
}

}
</code></pre>

<p>Here is My rest controller:</p>

<pre><code>@RestController
public class ProtocoloController {

@Autowired
private MessageSource messageSource;

@Autowired
private ProtocoloDAO protocoloDAO;

@RequestMapping(value = "/prot", method = RequestMethod.POST)
public void testar(@Valid @RequestBody Protocolo p) {
    Authentication auth = SecurityContextHolder.getContext().getAuthentication();
    System.out.println(auth.getAuthorities());
    System.out.println(messageSource.getMessage("protocolo.tamanho", null, null)); 
// IN THIS PART I'M ABLE TO PRINT THE MESSAGE IF VALIDATION IS DISABLED
    System.out.println(p.getProtocolo());
}
</code></pre>

<p>}</p>

<p>So, this code works fine and the method is not called since i'm calling the method with a invalid Protocolo. However, my angularJS client receives the response with the errors codes populated but with all the default messages empty since the validation is not seeing my loaded messages.properties. </p>

<p>Is there a way to make my Spring validation Interfaces or JSR-303 validation incorporate the loaded message.properties (messagesource) in spring boot ? How can i correct this ? If it's necessary i can paste my code sample of Spring Validation interfaces also.</p>

<p>Thank's a lot,</p>

<p>Tarcísio.</p>

<p>TEST CODE:</p>

<pre><code>@RestController
public class ProtocoloController {

@Autowired
private MessageSource messageSource;

@Autowired
private ProtocoloDAO protocoloDAO;

@RequestMapping(value = "/prot", method = RequestMethod.POST)
public void testar(@Valid @RequestBody Protocolo p, BindingResult bindingResult) {
    System.out.println(messageSource.getMessage("Min.protocolo.protocolo", null, null));
    if (bindingResult.hasErrors()) {
               System.out.println(bindingResult.getFieldError().getDefaultMessage());
System.out.println(bindingResult.getFieldError().getCode());
    }
    System.out.println(p.getProtocolo());
}
</code></pre>
