Student Entity in the Model

  package com.example.demo.model;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;



@Entity
@Table(name="student")
public class Student implements Serializable{
 
 private static final long serialVersionUID = -6899110682583120414L;

 @Id
 
    @Column(name="Stid")
 private int Stid;
 
    @Column(name="Name")
 private String Name;
    
    @Column(name="Programme")
 private String Programme;
 
 public Student() {
  //super();
 }

 
 public Student(int stid, String name, String programme) {
  super();
  Stid = stid;
  Name = name;
  Programme = programme;
 }

 

 @Override
 public String toString() {
  return "Student [Stid=" + Stid + ", Name=" + Name + ", Programme=" + Programme + "]";
 }
 
    
}

  

Student Repository

package com.example.demo.repository;

import org.springframework.data.repository.CrudRepository;

import com.example.demo.model.Student;

public interface StudentRepository extends CrudRepository {
   
}
  

Student Controller

   package com.example.demo.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

import com.example.demo.model.Student;
import com.example.demo.repository.StudentRepository;

@RestController
public class StudentController {

 @Autowired
 StudentRepository repository;
 
 @RequestMapping("/findall")
  @ResponseBody
 public String findall(){
  String result = "";
          for(Student student:repository.findAll()){
        result += " --- " +student.toString();
       }
 return result  ;
 }
 
 @RequestMapping("/findbystid")
  @ResponseBody
 public String findByStid(@RequestParam("stid") int stid){
  String result="";
           result=repository.findOne(stid).toString();
 return result  ;
 }
 
 @RequestMapping("/register")
 String register(Student student) {
  repository.save(new Student(10,"JPA","JPA Tut"));
  return "Student Registered";
 }

 
 
}
  

Main Class

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HelloJpaMySql1Application {

 public static void main(String[] args) {
  SpringApplication.run(HelloJpaMySql1Application.class, args);
 }
}

  

This is just a trick, hope it paved your way out.
