从 PUT 获取请求

  • 772

我创建了一个方法PUT，创建了一个控制器并尝试更正数据库中的数据，但PUT我收到了一个请求Bad Request, Required request body is missing。帮我找出问题所在

@PutMapping(value = "api/names/{username}")
public ResponseEntity<?> updatePerson(@RequestBody Person person, @PathVariable String username){
    Optional<Person> currentPerson = personRepository.findById(username);
    person.setOld(person.getOld());
    person.setEmail(person.getEmail());
    person.setPassword(person.getPassword());
    personRepository.save(person);
    return new ResponseEntity<Person>(person, HttpStatus.OK);
}
java

    它说你有一个空的请求正文。检查你是否正在发送它，它应该是这样的

    {old:10, email:xxx@zz.ru, password:1234}

    而且您的代码将无法正常工作，因为不会编辑现有人员，而是会创建一个新人员

    @PutMapping(value = "api/names/{username}")
public ResponseEntity<?> updatePerson(@RequestBody Person person, @PathVariable String username){
    Person currentPerson = personRepository.findById(username).orElseThrow(()->new NotFoundException("Person not found"));
    currentPerson.setOld(person.getOld());
    currentPerson.setEmail(person.getEmail());
    currentPerson.setPassword(person.getPassword());
    return new ResponseEntity<Person>(personRepository.save(currentPerson), HttpStatus.OK);
}

    那会更好
