java - null URL in testing with spring -

i testing method in spring controller , getting null pointer url when hits sendrequest method. test method follows:

@test public void testshowform() {     map<string, object> params = new hashmap<string, object>();     params.put("email", "testemail");     params.put("accesscode", keygenerator.getkey64());     string result = sendrequest("/userinfo.htm", get, usercontroller, params);     assertnotnull(result); } 

my helper class:

public class junitcontrollerhelper extends junithelper {  @autowired protected junitdatahelper junitdatahelper;  @autowired protected junitservicehelper junitservicehelper;  @autowired protected applicationcontext applicationcontext;  protected final string = "get"; protected final string post = "post";  protected mockhttpservletrequest request; protected mockhttpservletresponse response; protected handleradapter handleradapter;  @before public void setup() {    request = new mockhttpservletrequest();    response = new mockhttpservletresponse();    handleradapter = applicationcontext.getbean(handleradapter.class); }   public string sendrequest(string url, string method, object controller, map<string, object> params) throws exception {     request.setrequesturi(url);     request.setparameters(params);     request.setmethod(method);     request.setcontenttype("application/json");     handleradapter.handle(request, response, controller);     return response.getcontentasstring(); }  public static void assertsubmitsuccess(string json) {     if(!json.contains("\"success\":true"))         fail("submit returned unexpected errors"); }  public static void assertsubmiterror(string field, string json) {     if(!json.contains("\"success\":false") || !json.contains("\"errors\"") || !json.contains("\""+field+"\""))          fail("submit did not return expected errors"); } } 

the request reference variable of mockhttpservletrequest class , in controller labeled @requestmapping(method = requestmethod.get, value = "/userinfo"), appreciated.

applicationcontext.xml:

<import resource="classpath:springconfig/dao.xml"/> <import resource="classpath:springconfig/database.xml"/> <import resource="classpath:springconfig/service.xml"/> <import resource="classpath:springconfig/validator.xml"/> <import resource="data.xml"/> <import resource="controller.xml"/> <import resource="junit.xml"/> </beans>` 

i have tests in test directory, in controller.xml have:

<bean id="userinfocontroller" class="com.ck.web.controller.usercontroller"/> <bean class="org.springframework.web.servlet.mvc.annotation.defaultannotationhandlermapping"/> <bean id="jacksonmessageconverter" class="org.springframework.http.converter.json.mappingjacksonhttpmessageconverter"/></bean>   <bean class="org.springframework.web.servlet.mvc.annotationmethodhandleradapter"/></bean>` 

if once execution flow reaches sendrequest method, throws nullpointerexception, request or handleradapter object null because objects accessing , throw nullpointerexception.

if want check, try log 2 object state:

public string sendrequest(string url, string method, object controller, map<string, object> params) throws exception {      // log object state here or give print in console (as prefer)      request.setrequesturi(url);     request.setparameters(params);     request.setmethod(method);     request.setcontenttype("application/json");     handleradapter.handle(request, response, controller);     return response.getcontentasstring(); } 

can post complete class in order yo supply more detailed help?
