我正在使用 Spring Framework 4.0.7，以及 MVC 和 Rest

我可以安心地工作：

• @Controller
• ResponseEntity<T>

例如：

@Controller
@RequestMapping("/person")
@Profile("responseentity")
public class PersonRestResponseEntityController {

用方法（只是为了创建）

@RequestMapping(value="/", method=RequestMethod.POST)
public ResponseEntity<Void> createPerson(@RequestBody Person person, UriComponentsBuilder ucb){
    logger.info("PersonRestResponseEntityController  - createPerson");
    if(person==null)
        logger.error("person is null!!!");
    else
        logger.info("{}", person.toString());

    personMapRepository.savePerson(person);
    HttpHeaders headers = new HttpHeaders();
    headers.add("1", "uno");
    //http://localhost:8080/spring-utility/person/1
    headers.setLocation(ucb.path("/person/{id}").buildAndExpand(person.getId()).toUri());

    return new ResponseEntity<>(headers, HttpStatus.CREATED);
}

归还某物

@RequestMapping(value="/{id}", method=RequestMethod.GET)
public ResponseEntity<Person> getPerson(@PathVariable Integer id){
    logger.info("PersonRestResponseEntityController  - getPerson - id: {}", id);
    Person person = personMapRepository.findPerson(id);
    return new ResponseEntity<>(person, HttpStatus.FOUND);
}

工作正常

我可以这样做 ：

• @RestController（我知道它与@Controller+相同@ResponseBody）
• @ResponseStatus

例如：

@RestController
@RequestMapping("/person")
@Profile("restcontroller")
public class PersonRestController {

用方法（只是为了创建）

@RequestMapping(value="/", method=RequestMethod.POST)
@ResponseStatus(HttpStatus.CREATED)
public void createPerson(@RequestBody Person person, HttpServletRequest request, HttpServletResponse response){
    logger.info("PersonRestController  - createPerson");
    if(person==null)
        logger.error("person is null!!!");
    else
        logger.info("{}", person.toString());

    personMapRepository.savePerson(person);
    response.setHeader("1", "uno");

    //http://localhost:8080/spring-utility/person/1
    response.setHeader("Location", request.getRequestURL().append(person.getId()).toString());
}

归还某物

@RequestMapping(value="/{id}", method=RequestMethod.GET)
@ResponseStatus(HttpStatus.FOUND)
public Person getPerson(@PathVariable Integer id){
    logger.info("PersonRestController  - getPerson - id: {}", id);
    Person person = personMapRepository.findPerson(id);
    return person;
}

我的问题是：

1. 当 出于充分的理由 或 特定情况 时，必须强制使用一个选项而不是另一个选项
2. 如果（1）无关紧要，建议采用什么方法以及为什么。
