Doesnt have enough information to help. Kindly add some code(versions used), configuration/setup to get help. Explain a bit about the flow — Barath, Feb 14 '19 at 08:22
where you have used HttpSessionEvent ? share that piece of code. share the listener code — Barath, Feb 14 '19 at 09:33

This one is quite tricky

The interface is simple:

public interface HttpSessionListener extends EventListener {

    public default void sessionCreated(HttpSessionEvent se);

    public default void sessionDestroyed(HttpSessionEvent se);
}

But if we look at Apache Tomcat's implementation of WsSessionListener, we can see that it is missing the sessionCreated method, thus the JVM assumes the class is abstract

public class WsSessionListener implements HttpSessionListener{

    private final WsServerContainer wsServerContainer;


    public WsSessionListener(WsServerContainer wsServerContainer) {
        this.wsServerContainer = wsServerContainer;
    }


    @Override
    public void sessionDestroyed(HttpSessionEvent se) {
        wsServerContainer.closeAuthenticatedSession(se.getSession().getId());
    }
}

So how does Apache Tomcat compile their own code? In the Apache Tomcat implementation of the same interface, they have declared these methods as default thus implementing classes do not have to declare these methods.

    public default void sessionCreated(HttpSessionEvent se) {
    }

    public default void sessionDestroyed(HttpSessionEvent se) {
    }

The solution to your problem would be to remove the Servlet API dependency from your build script.

provided "javax.servlet:javax.servlet-api:3.1.0"

if you still need that API, replace it with Apache Tomcat's

provided "org.apache.tomcat:tomcat-servlet-api:9.0.19"

@RestController

@RequestMapping("/rest/hello") public class HelloResource {

private static final Logger LOGGER = LoggerFactory.getLogger(HelloResource.class);

@GetMapping(value = "/server")
public String hello() {
    LOGGER.info("Reached Server");
    return "HelloWorld";
}

@PostMapping(path = "/members", consumes = "application/json", produces = "application/json")
public void addMember(@RequestBody SendSmsRequestDto sendSmsRequestDto,HttpSession session) {
    LOGGER.info("sending SMS to contacts--" + sendSmsRequestDto);
}

}

In above hello() controller method is showing sleuth span Id and Trace Id. whereas addMember() controller method is throwing exception java.lang.AbstractMethodError: org.apache.tomcat.websocket.server.WsSessionListener.sessionCreated(Ljavax/servlet/http/HttpSessionEvent;)
