Lets see a practical example-
POJO:
public class Student{
private String firstName;
private String lastName;
public Student(String firstName,String lastName){
this.firstName = firstName;
this.lastName = lastName;
}
public void setFirstName(String firstName){
this.firstName = firstName;
}
public String getFirstName(){
return firstName;
}
public void setLastName(String lastName){
this.lastName= lastName;
}
public String getLastName(){
return lastName;
}
}
RestController:
@RestController
@RequestMapping("/api")
public class StudentRestController{
@GetMapping("/students")
public List<Student> getStudents(){
List<Student> students = new ArrayList<Student>();
students.add(new Student("lokman","hossain"));
students.add(new Student("sadia","muna"));
return students;
}
}
If we hit to that given end point (/api/students/) it will send a json array with two json object . So how it convert into json .
jackson convert the java pojo into json and sends back to the client .
