缺少必需的请求正文内容:org.springframework.web.method.HandlerMethod $ HandlerMethodParameter

ajax

将JSON数据从JSP传递到ResponseBody中的控制器时出错。

Ajax电话:

$.ajax({ 
                        url: "/BusinessReimbursment/addDepartment", 
                        method: 'POST', 
                        dataType: 'json', 
                        data: "{\"message\":\"abc\",\"success\":true}",
                        contentType: 'application/json',
                        mimeType: 'application/json',
                        success: function(data) { 
                            alert(data.id + " " + data.name);
                            commit(true);
                        },
                        error:function(data,status,er) { 
                            alert("error: "+data+" status: "+status+" er:"+er);
                        }
                    });

控制器:

@RestController
public class DepartmentController {

    @Autowired 
    @Qualifier("departmentService")
    private DepartmentService departmentService;

    @RequestMapping(value="/addDepartment", method={RequestMethod.POST})
    public @ResponseBody AjaxResponse addDepartment(@RequestBody AjaxResponse  departmentDTO){
        AjaxResponse response=new AjaxResponse();
        return response;
    }

AppConfig.java

@豆

public RequestMappingHandlerAdapter  annotationMethodHandlerAdapter()
{
    final RequestMappingHandlerAdapter annotationMethodHandlerAdapter = new RequestMappingHandlerAdapter();
    final MappingJackson2HttpMessageConverter mappingJacksonHttpMessageConverter = new MappingJackson2HttpMessageConverter();

    List<HttpMessageConverter<?>> httpMessageConverter = new ArrayList<HttpMessageConverter<?>>();
    httpMessageConverter.add(mappingJacksonHttpMessageConverter);

    String[] supportedHttpMethods = { "POST", "GET", "HEAD" };

    annotationMethodHandlerAdapter.setMessageConverters(httpMessageConverter);
    annotationMethodHandlerAdapter.setSupportedMethods(supportedHttpMethods);

    return annotationMethodHandlerAdapter;
}

请帮助我摆脱困境。我正在使用Spring 4,Jakson 2.3.0

如果我尝试POST请求,它将给出:org.springframework.web.HttpRequestMethodNotSupportedException:请求方法’POST’不支持

抱歉,..实际上是因为需要一个csrf令牌,所以我遇到了这个问题。我已经实现了spring安全性,并且启用了csrf。通过ajax调用,我需要传递csrf令牌。
