Micronaut controller error Page Not Found

I created a new micronaut app using
mn create-app example.micronaut.complete

After that I opened the project using intellij and added a new class as TestController to the project with code below:

package example.micronaut;

import io.micronaut.http.MediaType;

import io.micronaut.http.annotation.Controller;

import io.micronaut.http.annotation.Get;





@Controller("/hello")

public class TestController {



TestController(){}



@Get(value = "/", produces = MediaType.TEXT_PLAIN)

String getTest(){

    return "some string";

   }

}

But I am getting

{"_links":{"self":{"href":"/","templated":false}},"message":"Page Not Found"}

whenever I try to access the /hello end point

My application.yml looks like this:

micronaut:

    application:

        name: complete

    server:

        port: 8080

Without seeing more of your project it is hard to say what is wrong. I have pasted your code directly into a project and it works as expected. See the project at https://github.com/jeffbrown/khwaja404. The controller at https://github.com/jeffbrown/khwaja404/blob/a3e57623ed5b30e28eb95bfe0f4a4a5c9d123fd8/src/main/java/example/micronaut/TestController.java works fine...

package example.micronaut;



import io.micronaut.http.MediaType;

import io.micronaut.http.annotation.Controller;

import io.micronaut.http.annotation.Get;





@Controller("/hello")

public class TestController {



    // this empty constructor is not

    // needed, but isn't a problem...

    TestController() {

    }



    @Get(value = "/", produces = MediaType.TEXT_PLAIN)

    String getTest() {

        return "some string";

    }

}

The endpoint responds:

$ curl http://localhost:8080/hello

some string

One thing to look for is you may be missing the micronaut-inject-java and/or micronaut-inject dependency as expressed at https://github.com/jeffbrown/khwaja404/blob/a3e57623ed5b30e28eb95bfe0f4a4a5c9d123fd8/build.gradle#L27-L29.

Another is if you are running the app from the IDE (like IntelliJ IDEA), make sure you have annotation processors enabled in the build.

It is impossible to tell from your code sample if you are using Java or Groovy. The sample I linked is using Java. If you are using Groovy, of course you need the micronaut-inject-groovy dependency.

Thanks for the quick response. My bad I keep on forgetting to enable annotation processor. Thanks for pointing it out. I would like to know if there is a way to enable console debug logging in IDE for micronaut similar to spring boot.

If you don't know how to enable compile time annotation processors in Eclipse, you should post that as a separate question.

If you checkout the project I linked and run ./gradlew run (or gradlew run if you are using the basic Windows shell), you will see that the Micronaut endpoint works fine.
