rest - setting up MockMVC for Spring Restful Web Service -

so don't think there lot of questions on here on mockmvc spring testing springmvc controllers read through spring tutorial https://spring.io/guides/tutorials/rest/2/ there lot there trying simple on web service single id parameter. controller looked this:

@restcontroller @requestmapping("/demandrest") public class demandservicescontroller {      @autowired     demandservice demandservice;       @requestmapping(value = "/demand/{$id}", method = requestmethod.get, headers= "accept-application/jsson")     public demand readdemand(@requestparam(value="id", required=true) string id){         return demandservice.readdemand(new long(id));     } 

and wrote unit test uses org.springframework.test.web.servlet.mockmvc , attempt mock out (really stub) service call , assert on status code , getting status code 404. test looks this

import static org.mockito.mockito.when; import static org.springframework.test.web.servlet.request.mockmvcrequestbuilders.get; import static org.springframework.test.web.servlet.result.mockmvcresultmatchers.status; import static org.springframework.test.web.servlet.setup.mockmvcbuilders.standalonesetup;  import org.junit.after; import org.junit.before; import org.junit.test; import org.mockito.injectmocks; import org.mockito.mock; import org.mockito.mockitoannotations; import org.springframework.http.mediatype; import org.springframework.http.converter.json.mappingjackson2httpmessageconverter; import org.springframework.test.web.servlet.mockmvc;  public class demandservicescontrollertest {      mockmvc mockmvc;      @injectmocks     demandservicescontroller demandservicescontroller = new demandservicescontroller();      @mock     demandservice demandservice;      @before     public void setupunittest() throws exception {         mockitoannotations.initmocks(this);         this.mockmvc = standalonesetup(demandservicescontroller).                 setmessageconverters(new mappingjackson2httpmessageconverter()).build();     }      @after     public void teardown() throws exception {     }      @test     public void testreaddemandstate() throws exception {         long id = new long(99);     demand demand = new demand();         demand.setdescription("description");         when(demandservice.readdemand(id)).thenreturn(demand );         this.mockmvc.perform(get("/demandrest/demand/{id}",id.tostring()).                 accept(mediatype.application_json)).andexpect(status().isok());     }  } 

i couple other things i'll mention before hit post. looking @ example tutorial tried pick stuff use isn't exact copy. 1 big difference had do, , suspect has how in pom testing plugin configured, had instantiate controller example smart enough know create instance. also, example relies on gradle project set , have pom file project. not sure if makes difference. seems new stuff pretty simple example. in advance help.

you should fix requestmapping from

@requestmapping(value = "/demand/{$id}", method = requestmethod.get, headers= "accept-application/jsson") 

to

@requestmapping(value = "/demand/{id}", method = requestmethod.get, headers= "accept=application/json") 

{$id} should {id} , headers have typo , incorrect syntax. perhaps should consider using produces , consumes instead of headers param also.

this should fix 404 status.
