[FIXED] PUT request wont go through unless I provide ID in body

Issue

I am using path variable in url in order to update my object. How can I modify my code for it to work without needing to provide an id in the post body if I already got it in the url?

    public class Person {
        
        private String name;
        private UUID id;
        
        public(UUID id, String name) {
            this.id = id;
            this.name = name;
        }
        ...getters
    } 

Service class

public int updatePerson(UUID id, Person person) {
        String sql = "UPDATE person SET name = ? WHERE id = ?";
        return jdbcTemplate.update(sql, person.getName(), person.getId());
    }

Controller

 @PutMapping("/{id}")
    public int updatePerson(@PathVariable UUID id, @RequestBody Person person) {
        return personService.updatePerson(id, person);
    }

Solution

Just change your Service class to use id instead of person.getId():

public int updatePerson(UUID id, Person person) {
    String sql = "UPDATE person SET name = ? WHERE id = ?";
    return jdbcTemplate.update(sql, person.getName(), id);
}
