code have written is:

controller class:

@enablewebmvc @controller public class controller {  @requestmapping(value = "/app/data", method = requestmethod.post, produces = mediatype.application_json_value, consumes = mediatype.application_json_value)     public responseentity<responsedata> datainquiry(             @requestbody requestdata requestdata,             @requestheader(value = constants.id, required = false) string transactionid) {         //do action         return new responseentity<responsedata>(responsedata, headers, httpstatus.ok); } 

controllertest class:

@runwith(springjunit4classrunner.class) @contextconfiguration({"classpath*:spring/beanrefcontext.xml"}) @webappconfiguration public class controllertest{      public static final mediatype application_json_utf8 = new mediatype(mediatype.application_json.gettype(),             mediatype.application_json.getsubtype(),             charset.forname("utf8"));  private mockmvc mockmvc;      @autowired      webapplicationcontext wac;   objectmapper mapper;     annotationmethodhandleradapter adapter;     mockhttpservletrequest request;     mockhttpservletresponse response;  @before     public void setup() {         system.out.println("before method execution in commoninquirycontrollertest class ");         //this.mockmvc = mockmvcbuilders.webappcontextsetup(this.wac).build();         mockitoannotations.initmocks(this);         this.mockmvc = mockmvcbuilders.webappcontextsetup(this.wac).dispatchoptions(true).build();          adapter = new annotationmethodhandleradapter();         request = new mockhttpservletrequest();         response = new mockhttpservletresponse();         mapper = new objectmapper();     }  @test     public void inquirydatatest() throws exception, jsonprocessingexception     {         requestdata anobject = new requestdata();          anobject.setid("1234");         anobject.setqualifier("somedata");               mapper = new objectmapper();         mapper.configure(serializationfeature.wrap_root_value, false);         objectwriter ow = mapper.writer().withdefaultprettyprinter();         string requestjson=ow.writevalueasstring(anobject );          assertnotnull(anobject.getid());         assertnotnull(anobject.getqualifier());          resultactions resultactions = mockmvc                 .perform(post("/app/data")                 .contenttype(mediatype.application_json)                 .accept(mediatype.application_json)                 .content(mapper.writevalueasbytes(requestjson)));              resultactions.andexpect(status().isok());              //this print response json string             resultactions.anddo(mockmvcresulthandlers.print());          assert.assertequals(200, response.getstatus()); }

even though enable webmvc, need scan controller auto register controller & url mappings.component-scan scans packages find , register beans within application context.

<context:component-scan base-package="com.mycompany.xyz" /> 

i doubt component scanning missing in context xml.if add statement in beanrefcontext.xml.
