Question

我想执行JSON消息的POST，并希望转换为Employee Object。 JSON消息是{"employee":{"id":2231,"name":"jeffarry2231","niNumber":"SN10KTL"}} 。

员工对象

public class Employee {
    private Long id;
    private String name;
    private String niNumber;
    ...
}

EmployeeController

@Controller
public class EmployeeController {

   @RequestMapping(value = "/employee/add/", method = RequestMethod.POST)
    public void addEmployee(Employee employee){
       System.out.println(employee.getName());
    }
}

发布请求的RestTemplate是

@Test
public void postMethod() {
    RestTemplate restTemplate = new RestTemplate();
    String jsonEmployee = "{'id':2231,'name':'jeffarry2231','niNumber':'SN10KTL'}}";

    HttpHeaders headers = new HttpHeaders();
    headers.setAccept(newArrayList(MediaType.APPLICATION_JSON));
    HttpEntity<String> requestEntity = new HttpEntity<String>(jsonEmployee, headers);
    restTemplate.exchange("http://localhost:8080/employee/add/", POST, requestEntity, String.class);
}

applicationContext.xml有

<mvc:annotation-driven/>

我希望在默认情况下使用MappingJacksonHttpMessageConverter，但它似乎没有转换，不知道我在这里缺少什么！

尝试添加@RequestBody注释：

@RequestMapping(value = "/employee/add/", method = RequestMethod.POST)
public void addEmployee(@RequestBody Employee employee){
   System.out.println(employee.getName());
}

默认JSON到对象映射不起作用
