While running the code getting whitelabel page error as shown in Postman Kindly help with what is going wrong: Note: All classes are below main class as per few checked solution. Issue remain same with @ComonentScan too.
Postman error: { "timestamp": "2022-08-05T12:08:42.938+00:00", "status": 404, "error": "Not Found", "path": "/dept/" }
Json given: { "deptName":"XYZ", "address": "XYZ" }
Code:

package com.microservice.Entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
//import javax.persistence.Table;
import lombok.AllArgsConstructor;
import lombok.Data;

@Entity
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Department {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int departmentId;
private String deptName;
private String address;
}
Service:
package com.microservice.Service;
import com.microservice.Entity.Department;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.microservice.Repository.DepartmentRepository;
@Service
public class DepartmentService {
@Autowired
private DepartmentRepository departmentRepository;
public Department getByID(int departmentId)
{
return departmentRepository.findByDepartmentId(departmentId);
}
public Department saveDepartment(Department department) {
return departmentRepository.save(department);
}
}
Controller:
package com.microservice.FController;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import com.microservice.Entity.Department;
import com.microservice.Service.DepartmentService;
@RestController
@RequestMapping("/dept")
public class DepartmentController {
@Autowired
private DepartmentService departmentservice;
@PostMapping("/")
public Department saveDepartment(@RequestBody Department department){
return departmentservice.saveDepartment(department);
}
@GetMapping("/{id}")
public Department getByID(@PathVariable("id") Integer departmentId ) {
System.out.println("Inside get id controller method");
return departmentservice.getByID(departmentId);
}
}
Repository:
package com.microservice.Repository;
import org.springframework.data.jpa.repository.JpaRepository;
import com.microservice.Entity.Department;
public interface DepartmentRepository extends JpaRepository<Department,Integer> {
Department findByDepartmentId(int departmentId);
}
Main Class:
package com.microservice.Departmentservice;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
public class DepartmentServiceApplication {
public static void main(String[] args) {
SpringApplication.run(DepartmentServiceApplication.class, args);
}
}
I've tried your code and seams to be correct. Just two check you must done this the URL that you request in Postman :
POST
request to the URL not GET
/
in @PostMapping("/")
on top of saveDepartment
method. So, you have to make your post request as:http://localhost:9009/dept/
Notice the trailing slash at the end of the request.
Otherwise you get 404 not found error if you missed this character /
Another way is just simply remove /
from @PostMapping("")
on top of saveDepartment
method:
@PostMapping("")
public Department saveDepartment(@RequestBody Department department){
return departmentservice.saveDepartment(department);
}
