Newbie learning a first REST API example in Springboot. I have this snippet in my implementation class giving the error ""cannot make a static reference to a the non-static method getId() from the type Course". The getId() method is not static but the invocation appears to be from a static method leading to this error...im confused. Appreciate any help.
@Override
public Course getCourse(long courseId) {
Course c=null;
for (Course course:list)
{
if(Course.getId()==courseId)
{
c=course;
break;
}
}
return c;
}
My controller class:
@GetMapping("/courses/{courseId}")
public Course getCourse(@PathVariable String courseId)
{
return this.courseService.getCourse(Long.parseLong(courseId));
}
My service class:
public interface CourseService {
public List<Course> getCourses();
public Course getCourse(long courseId);
}
My entity class:
public class Course {
private long id;
private String title;
private String description;
public Course(long id, String title, String description) {
super();
this.id = id;
this.title = title;
this.description = description;
}
public long getId() {
return id;
}
Was expecting this will compile.
