I am getting error in my controller Saying Null Pointer Exception while When I don't perform the testing. Everything works fine.
Controller :
@RequestMapping(value = "/studentinsection/{sectionId}", method = RequestMethod.GET)
public ModelAndView studentInSectionForm(@ModelAttribute("studentInSectionFormData") StudentInSectionForm studentInSectionFormData,
@PathVariable Integer sectionId,
ModelMap model) {
ArrayList<StudentInSections> studentInSectionList = (ArrayList<StudentInSections>)
studentInSectionsService.retrieveAllStudentInSections(sectionId, 1);
StudentSection studentSection = studentSectionService.retrieveStudentSection(sectionId);
logger.info("section Name is:" + studentSection.getSectionName());
ArrayList<User> userList = new ArrayList<User>();
for (StudentInSections studentInSections : studentInSectionList) {
String studentName =
(userService.retrieveUserName(studentInSections.getStudentId(), 1));
User users = userService.retrieveUser(studentName);
userList.add(users);
}
logger.info("sectionId is " + sectionId);
ArrayList<User> allStudents = (ArrayList<User>)
userService.retrieveAllStudents();
studentInSectionFormData.setStudentInSectionList(studentInSectionList);
model.addAttribute("studentList", allStudents);
model.addAttribute("userList", userList);
model.addAttribute("studentSectionName", studentSection.getSectionName());
model.addAttribute("studentSectionId", studentSection.getSectionId());
return new ModelAndView("studentinsection", "studentInSectionFormData", studentInSectionFormData);
}
Testing is as follow:
@Test
public void testStudentInSectionForm() throws Exception {
mockMvc.perform(get("/studentinsection/1"))
.andExpect(status().isFound())
.andExpect(redirectedUrl("studentinsection"));
}
this is passing everything into the controller fine even sectionId is getting printed 1 in logger than also studentin sectionList returns nullMointerException. help me to resolve my problem.. Thanx
