Validate Bean in Spring boot

Is there a way in spring boot to validate properties in a bean? For Example, consider an Employee Bean consisting of following properties -

  1. id - must start with 01,02,22
  2. Department - Should be any of the one - D1, D2, D3
  3. Name - Must not contain any digits and max length of 10 characters.

I can have a separate method and validate the bean every time but looking for some better way to implement this using spring boot.

You could use spring boot validation to validate your patterns. Add this dependency to your gradle file implementation('org.springframework.boot:spring-boot-starter-validation') https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-validation checkout the latest version

class Employee {

  @Pattern(regexp = "^(01|02|22).+$")
  private String id;

  @Size(max = 10)
  @Pattern(regexp = "^[^0-9]+$")
  private String name;

  @Pattern(regexp = "^D[1-3]$")
  private String department;
  
}

And in your request

@RestController
class EmployeeRequest {

  @PostMapping("/registerEmployee")
  ResponseEntity<String> registerEmployee(@Valid @RequestBody Employee employee) {
    return ResponseEntity.ok("valid");
  }
}

Note: I am not sure about syntax of regex but you should define your regex for your business requirements.
