For Jersey 2 to work along with Spring MVC endpoints in a Spring Boot application, I would suggest to make sure your application.yml (or .properties makes such distinction, something like:
...
# Spring MVC dispatcher servlet path. Needs to be different than Jersey's to enable/disable Actuator endpoints access (/info, /health, ...)
server.servlet-path: /
# Jersey dispatcher servlet
spring.jersey.application-path: /api
...

If you are integrating Jersey 1 with Spring MVC endpoints in a Spring Boot app, Spring Boot doesn't provide a jersey 1 starter so everything needs to be "manually" configured, but basically if your Jersey servlet is mapped to "/", you would need to configure it to let pass 404 to the servlet container for further handling (maybe a Spring MVC or plain servlet endpoint). Something like:
Jersey 1 resources configuration:
@ApplicationPath("/")
public class DemoResourcesConfig extends PackagesResourceConfig {
private static final Map<String, Object> properties() {
Map<String, Object> result = new HashMap<>();
result.put(PackagesResourceConfig.PROPERTY_PACKAGES, "com.sun.jersey;com.asimio.api.demo1.rest");
// To forward non-Jersey paths to servlet container for Spring Boot actuator endpoints to work.
result.put("com.sun.jersey.config.feature.FilterForwardOn404", "true");
result.put(JSONConfiguration.FEATURE_POJO_MAPPING, "true");
return result;
}
public DemoResourcesConfig() {
super(properties());
}
...
}
Jersey 1 resource implementation:
package com.asimio.api.demo1.rest;
...
@Component
@Path("/actors")
@Produces(MediaType.APPLICATION_JSON)
public class ActorResource {
@GET
public List<Actor> findActors() {
...
}
@GET
@Path("{id}")
public Actor getActor(@PathParam("id") String id) {
...
}
...
}
ServletContextInitializer bean
@Bean
public ServletContextInitializer servletInitializer() {
return new ServletContextInitializer() {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
final ServletRegistration.Dynamic appServlet = servletContext.addServlet("jersey-servlet", new SpringServlet());
Map<String, String> filterParameters = new HashMap<>();
// Set filter parameters
filterParameters.put("javax.ws.rs.Application", "com.asimio.api.demo1.config.DemoResourcesConfig");
appServlet.setInitParameters(filterParameters);
appServlet.setLoadOnStartup(2);
appServlet.addMapping("/*");
}
};
}
application.yml
...
# For Spring MVC to enable Endpoints access (/admin/info, /admin/health, ...) along with Jersey
server.servlet-path: /admin
...
