Spring JDBC Unable to insert - mysql

Question

I am new to SpringBoot and I am using SpringBoot with JDBC for making an API. The INSERT is not working properly, I had made ID Unique and AutoIncremeneted it. Before I was inserting the ID and it was causing no problems.I am using MySql as the database.
The JSON I am using in POST is:
{
"name":"Name",
"email":"namegmail.com",
"dob":"2000-04-09",
"age":21
}
I am getting this Error.
{
"timestamp": "2021-06-20T13:10:16.925+00:00",
"status": 415,
"error": "Unsupported Media Type",
"message": "Content type 'application/octet-stream' not supported",
"path": "/api/v1/NewStudent"
}
Controller

#GetMapping("/AllStudents")
public List<StudentClass> getAllStudents(){

}
StudentDao
public class StudentDaoClass implements StudentDao{

I think your rest call is not even reaching the jdbc part as there is problem in your rest request. I believe you are not setting the content-type properly. Try making below changes and see.
When sending the request please set 'Content-Type' header property to 'application/json'
and enhance your below handler method what is consumes.
#PostMapping(path="/NewStudent", consumes="application/json")
public void registerNewStudent(#RequestBody StudentClass studentClass){
studentService.addNewStudent(studentClass);
}
Try debugging your application. Your rest call should reach your above handler method.
