Test case: @Test public void testPutMethod() { HttpEntity entity = new HttpEntity(new Student("15", "John", 99),headers); ResponseEntity response = testRestTemplate.exchange( createURLWithPort("/students"), HttpMethod.PUT, entity, Student.class); System.out.println(response.getBody()); assertEquals(HttpStatus.ACCEPTED, response.getStatusCode()); }

Controller put method changes : Note : This put method will update ID and AGE. @PutMapping(value ="/students", consumes=MediaType.APPLICATION_JSON_VALUE)

public ResponseEntity<Student> updateStudent(@RequestBody Student student) {
	System.out.println(student.getName());
	if(userRepo.findByName(student.getName()).isEmpty()) {

	}else {
