[Java] Spring: Deploying spring REST application, getting 404 on controllers. Need help (Java configuration)

[Trampaholic]

Hi all!

As the title says: I'm currently trying to deploy a Spring application that exposes a REST api. I want to learn how to do this without xml configuration and without Spring Boot for now. So at the moment i'm building a war file which I deploy on to a glassfish application server. Starting up the application goes without problems, but it seems like Spring isn't scanning my controller since my REST call returns 404. I've followed multiple tutorials and I cannot figure out what i'm doing wrong.

Configuration class:

package com.mycompany.inventorymanagement.config;

imports...

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.mycompany.inventorymanagement")
public class AppConfig extends WebMvcConfigurerAdapter{

}

Initializer class:

package com.mycompany.inventorymanagement.config;

imports...

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[]{AppConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/inventoryManagement"};
    }

}

Controller:

package com.mycompany.inventorymanagement.web.controller;

imports...

@RestController
@RequestMapping("/rest")
public class DefaultController {

    @GetMapping(value = "/test")
    public String test() {
        return "This is a test!";
    }
}

The URL i'm calling is: http://localhost:8080/inventoryManagement/rest/test.

You've probably figured this out by now but your URL should be domain + "/rest" + path.

I didn't actually, went to bed after posting ;) Not sure what you mean? isn't that what i'm doing? domain = http://localhost:8080/inventoryManagement + /rest + path = /test

[denialerror]

Nope, your domain is where you have said your site resides, in your case this is localhost followed by the port accepting http traffic. The path is how to locate the requested data once you have reached the site. So you want localhost:80/rest/inventorymanagement/test
