Хорошо, поэтому я кратко объясню. Я создал API с Maven, Eclipse и Spring MVC, и он отлично работает при работе с «tomcat7: run». (Порт 9090)
Проблема возникает при запуске сервера и развертывании там API. Сервер работает как шарм, http //: localhost: 8080 работает отлично, проблема возникает, когда я пытаюсь сделать запросы к API, потому что кажется, что он не существует, так как он не отвечает ни на один запрос ( 404 каждый раз).
Проект развернут, если я смотрю его из manager / html, я вижу, что он запущен, поэтому я не имею ни малейшего представления, в чем может быть проблема.
Я пытался найти и найти ошибку, но достиг своего предела. Заранее спасибо!
Если вы хотите увидеть какой-либо код, просто спросите, потому что я не знаю, какой код загрузить в этом случае.
Это один из классов контроллеров:

import com.autentia.spring.model.Course;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@CrossOrigin("*")
@RestController
public class CourseController {
@Autowired
private CourseService courseService;
@RequestMapping(value = "/", method = RequestMethod.GET, headers = "Accept=application/json") //This method was a get, post is just for testing
public ResponseEntity<String> welcome(@RequestBody String body) {
System.out.println("In the UserController::index");
return new ResponseEntity<>("It works!", HttpStatus.OK);
}
@RequestMapping(value = "/courses", method = RequestMethod.GET)
public ResponseEntity<List<Course>> users() {
System.out.println("Getting all courses");
List<Course> list = courseService.getAllCourses();
System.out.println("List: " + list);
return ResponseEntity.ok().body(list);
}
@RequestMapping(value = "/courses", method = RequestMethod.POST, headers = "Accept=application/json")
public ResponseEntity<String> insertCourse(@RequestBody Course course) {
System.out.println("Inserting course: " + course);
course.setId((long)0);
// boolean teacherSaved = teacherService.insertTeacher(teacher);
courseService.insertCourse(course);
return new ResponseEntity(course.getId(), HttpStatus.OK);
}
}
