GraalVM: DependencyInjectionException in native Micronaut application with Micronaut Email #8038
-
|
Hi 👋🏻 I have a pretty simple Micronaut application containing one controller that forwards a http request to MailJet (using Micronaut Email). @Controller("/api/v1/message")
@Validated
@Slf4j
@RequiredArgsConstructor
public class MailController {
private final EmailSender<?, ?> emailSender;
private final MailConfiguration mailConfiguration;
@Post
public HttpStatus sendMessage(@Valid @Body MessageRequest request) {
log.info("Received message {}", request);
final String mailBody =
"Neue Nachricht von "
+ request.name()
+ " «"
+ request.email()
+ "»."
+ "\n\n"
+ "Betreff: "
+ request.subject()
+ "\n\n"
+ request.message();
emailSender.send(
io.micronaut.email.Email.builder()
.from(mailConfiguration.getFrom())
.to(mailConfiguration.getTo())
.subject("Neue Anfrage auf Webseite von " + request.name())
.body(mailBody));
return HttpStatus.ACCEPTED;
}
@Serdeable
@Introspected
public record MessageRequest(
@NotBlank String name,
@Email String email,
@NotBlank String subject,
@NotBlank String message) {}
}Furthermore I have an immutable configuration instance @ConfigurationProperties(value = MailConfiguration.PREFIX)
public interface MailConfiguration {
String PREFIX = WebsiteConfiguration.PREFIX + ".mail";
@Email
String getTo();
@Email
String getFrom();
}When I run the application as a FatJar everything works as expected. But when I run the native compiled application Micronaut has trouble to inject the I'm pretty new to native images and due to that I bit stuck with this error. Can you maybe give me some hints how to analyse (and fix) this problem? Btw. I have set the Micronaut context logger to <configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<withJansi>true</withJansi>
<!-- encoders are assigned the type
ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->

Just curious, have you tried without Lombok? |

@graemerocher good point. I tried w/o Lombok and updated the controller and removed the dependencies. @Controller("/api/v1/message")
@Validated
public class MailController {
private final EmailSender<?, ?> emailSender;
private final MailConfiguration mailConfiguration;
private static final Logger log = getLogger(MailController.class);
public MailController(EmailSender<?, ?> emailSender, MailConfiguration mailConfiguration) {
this.emailSender = emailSender;
this.mailConfiguration = mailConfiguration;
}
@Post
public HttpStatus sendMessage(@Valid @Body MessageRequest request) {
log.info("Received message {}", request);
final String mailBody =
"Neue Nachricht von "
+ request.name()
+ " «"
+ request.email()
+ "»."
+ "\n\n"
+ "Betreff: "
+ request.subject()
+ "\n\n"
+ request.message();
emailSender.send(
io.micronaut.email.Email.builder()
.from(mailConfiguration.getFrom())
.to(mailConfiguration.getTo())
.subject("Neue Anfrage auf Webseite von " + request.name())
.body(mailBody));
return HttpStatus.ACCEPTED;
}
@Serdeable
@Introspected

}
version = "0.1"

I finally found the issue. It's not Micronaut related. Initially I omitted the Spotless Gradle Plugin I use in the project. I have now added it the I worked around it by excluding the spotless tasks in my GitHub Actions workflow. ./gradlew -s check buildNativeLayersTask dockerPrepareContext -x spotlessInternalRegisterDependencies -x spotlessJava -x spotlessJavaCheck -x spotlessCheckSo it's not a Lombok issue but rather a problem with the interaction of the Spotless plugin and the Micronaut plugin. |
