This  tutorial will teach you how to do the full stack development application using Spring boot React Tailwind CSS. that are CREATE, RETIEVE, UPDATE and DELETE and SEARCH using mysql Database. The INSERT, SELECT, UPDATE and DELETE statements can be used in any database system, because this is support by all relational database systems.

Crud function how to perform the RESTful Web Service let discuss with following annotations.

@PostMapping:  annotation which used to create new record.
@GetMapping:   annotation which used to reads a record.
@RequestMapping: annotation which used to search the record.
@PutMapping:   annotation which used to update the existing record.
@DeleteMapping:  annotation which used to delete the record.

Create the Package Student Controller

Inside the Package create the class StudentController.java

StudentController.java

package com.studentapp.studentapplication.controller;

import com.studentapp.studentapplication.dto.StudentDTO;
import com.studentapp.studentapplication.dto.StudentSaveDTO;
import com.studentapp.studentapplication.dto.StudentUpdateDTO;
import com.studentapp.studentapplication.entity.Student;
import com.studentapp.studentapplication.service.StudentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
@CrossOrigin
@RequestMapping("api/v1/student")
public class StudentController {


    @Autowired
    private StudentService studentService;

    @PostMapping(path = "/save")
    public String saveStudent(@RequestBody StudentSaveDTO studentSaveDTO)
    {
        String id = studentService.addStudent(studentSaveDTO);
        return id;
    }

    @GetMapping(path = "/getAllStudents")
    public List<StudentDTO> getAllStudent()
    {
        List<StudentDTO> allStudents = studentService.getAllStudents();
        return allStudents;
    }


    @PutMapping(path = "/update")
    public String updateStudent(@RequestBody StudentUpdateDTO studentUpdateDTO)
    {
        String id = studentService.updateStudent(studentUpdateDTO);
        return id;
    }


    @DeleteMapping(path = "/deletestudentid/{id}")
    public String deleteStudent(@PathVariable(value = "id")int id)
    {
        boolean deletestudent = studentService.deleteStudent(id);
        return "deleteddd!!!!!";
    }

}

@Entity
@Table(name="student")
public class Student {

    @Id
    @Column(name="student_id",length = 50)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int studentid;

    @Column(name="student_name",length = 50)
    private String studentname;


    @Column(name="address",length = 100)
    private String address;

    @Column(name="mobile",length = 100)
    private int  mobile;


    @Column(name="active",columnDefinition = "TINYINT default 1")
    private boolean  active;


    public Student(int studentid, String studentname, String address, int mobile, boolean active) {
        this.studentid = studentid;
        this.studentname = studentname;
        this.address = address;
        this.mobile = mobile;
        this.active = active;
