Controller mappings to some functions are not working in the deployed spring boot application

Question

I have deployed the spring boot application in a vm in tomcat server. When I load the page, I get to see only the static part, none of the uri mapping to the ajax functions in the controller seem to work here. But the same works fine in my local application. Can anyone please help. I am attching the code of my rest controller class below.

import org.springframework.data.rest.webmvc.RepositoryRestController;

        System.out.println("last week"+lastWeekInMonth);
        model.addAttribute("lastweek", lastWeekInMonth);

        return submitList.toString();
    }   
}

out of this, only those that returns model and view woorks and all other mappings to functions called from angular js ajax calls are not invoked, it shows in the console that

angular.js:8611 GET http://172.16.77.83:8083/getCurrentWeek 404 (Not Found)

Similarly for other calls as well. Because of which, the data in my html pages are not populated properly. The same application works fine in my local machine. Only in this external vm, it shows this problem.

Adding the ajax call code of the js file.

function getCurrentWeek(){
        console.log("in ajax");

        $http({
            method : "GET",
            url : "/getCurrentWeek"
        }).then(function mySucces(response) {
            $scope.currentWeek=response.data;
              var j=parseInt($scope.currentWeek)-1;


              $('table.ui-datepicker-calendar tr:eq('+$scope.currentWeek+')').css({"border":"3px solid #e1e1e1"});
              var weekVal=$('#weekvalues a')[j];
             weekVal.style.border="3px solid #50a8e5";
              weekVal.style.paddingRight="2px";
              weekVal.style.paddingLeft="2px";
              weekVal.style.paddingTop="1px";

        }, function myError(response) {
            //$scope.dateRange = response.statusText;
        });

    }

Thanks, Poorna.

I do not see any error in server logs. And, I am able to see all these classes deployed in webapps. — Eli Johnes, Mar 23 '16 at 06:53
in my opinion the problem hear is in your js could post the your js? becoause for example if in your ajzx request you are coupled with localhost it is clear that in your machin work an in vm no — Valerio Vaudi, Mar 23 '16 at 07:48

It appears to me that you're using a different context path when you're deploying on the Tomcat container (inside the VM). If you ran the application locally using mvn spring-boot:run, or by launching the JAR without setting the server.contextPath property, you probably ran it on the root context within the embedded container.

The URL http://172.16.77.83:8083/getCurrentWeek operates on that root context, while on Tomcat you probably have to go to http://172.16.77.83:8083/MyApplicationNam/getCurrentWeek.

To solve this issue there are a few solutions:

1. Deploying the application on the root context:

Rename the WAR to ROOT.war before deploying it on Tomcat
Changing the context path in server.xml

Check this answer for more information about it: Deploying my application at the root in Tomcat

2. Using relative URLs (probably the best solution):

By using relative URLs you will always work relative based on your HTML page. If the HTML page is within the same application, the context path will also be applied to the HTML page, so relatively towards the HTML page REST API should always stay the same.

$http({
    method : "GET",
    url : "./getCurrentWeek"
})

For more information about this topic check these answers: Absolute vs relative URLs

Your application which is a RESTful service is deployed on tomcat server. And your trying to access these services in AngularJS which is deployed on different server.

And you will have to add the CORS filtering(CROSS Domain origin access), to give access to the HTTP verbs for cross services.(Domain to Domain access) Add the following Bean in your class path, it will work fine.

@Component
public class CORSFilter implements Filter {

    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
        chain.doFilter(req, res);
    }

    public void init(FilterConfig filterConfig) {}

    public void destroy() {}

}

Why do you think the OP, Poorna, is running the AngularJS code on a different server? Considering that she has issues to show her views (= HTML) and her REST API in the same controller, I would rather consider that both are running on the same application. Also, even if it was a CORS issue, in Spring it's a lot easier using the `@CrossOrigin` annotation: http://docs.spring.io/spring-framework/docs/current/spring-framework-reference/html/cors.html – g00glen00b Mar 23 '16 at 12:23
@g00glen00b Why should n't I consider it? I just considered that both are on different server, with that approach I suggested my answer. But your consideration was correct and gave good answer I accept it, that doesnt mean that you discourage other answer. – Hareesh Mar 24 '16 at 05:20
because she has multiple `ModelAndView`'s on her controller, which means she is serving HTML's as well on her application. And even if the answer was correct, then it would have been a lot easier to use `@CrossOrigin`, rather than adding a CORS filter like in regular Java applications. – g00glen00b Mar 24 '16 at 06:39
