Configuring Jersey with Spring boot

Question

I am trying to configure the spring boot with jersey but it seems jersey annotations are not working with spring boot. can you please help me out.

I have tried @RestController instead of @Component and @RequestMapping instead of @Path in service class.

Spring Boot Application Xml

package org.hotel;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ReservationApplication {

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

}

service class with jersey annotations

package org.hotel.webservices;
import org.springframework.stereotype.Component;
import javax.ws.rs.GET;
import javax.ws.rs.Path;

@Component
@Path("/rooms")
public class AddRoomService {

    @GET
    public String addRoomService(){
        return "success";
    }
}

Nice tutorial online about this: Spring Boot Jersey Example July 14, 2017 by Lokesh Gupta. This seems to be the part you're missing.

Jersey Configuration

1: Now we have a JAX-RS resource and we want to access it from spring boot application which include Jersey dependency. Let’s register this resource as Jersey resource.

package com.howtodoinjava.jerseydemo;

import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.stereotype.Component;

@Component
public class JerseyConfig extends ResourceConfig 
{
    public JerseyConfig() 
    {
        register(UserResource.class);
    }
}

Look at the @Component annotation. It enables this class to be registered while spring boot auto scans the java classes in source folder.

2: ResourceConfig provides advanced capabilities to simplify registration of JAX-RS components. 3: Extend spring boot application with SpringBootServletInitializer.

package com.howtodoinjava.jerseydemo;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class JerseydemoApplication extends SpringBootServletInitializer 
{
    public static void main(String[] args) 
    {
        new JerseydemoApplication().configure(new SpringApplicationBuilder    (JerseydemoApplication.class)).run(args);
    }
}
