javajbossjax-rswildflyresteasy

WildFly always returns the 404 Not Found

Whatever I do, WildFly returns the 404 code to me

I'm using Java 22.0.1, Intellij Idea and WildFly 32.0.1.Final.

I also tried to run similar and working projects with GitHub on this configuration, but I ran into the same problem

I have created a simple Maven project with the following files:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>ru.sosnilosm.manager</groupId>
    <artifactId>task-manager</artifactId>

    <packaging>war</packaging>
    <version>1.0-SNAPSHOT</version>
    <name>task-manager REST-API</name>

    <dependencies>
        <dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-jaxrs</artifactId>
            <version>3.15.6.Final</version>
            <scope>provided</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.3.2</version>
                <configuration>
                    <!-- So maven doesn't require web.xml.tmp -->
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

package ru.sosnilosm.manager.controller;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/api")
public class JaxRsApplication extends Application {
}

package ru.sosnilosm.manager.controller;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path("/test")
public class TestController {
    @GET
    @Produces("text/plain")
    public String test() {
        return "test";
    }
}

Nevertheless, when making a request via Postman at the URL http://localhost:8080/task-manager-1.0-SNAPSHOT/api/test, I always get a 404 Not Found Postman results

where did I go wrong?

Solution

    Package

    mvn clean package

    Wildfly web console install

    target/task-manager.war

    Test

    Note that wildfly 32 supports jakarta ee 10, so the related package names are changed to jakarta.xxx.
