我正在尝试使用以下 jQuery 1.6通过 AJAX 在 Spring ( 3.2.0 ) 中调用一个方法。

function updateRoleEnabled(id)
{
    $.ajax({
            datatype:"json",                        
            type: "PUT",
            url: "/wagafashion/ajax/UpdateUserRole.htm",
            data: "id="+id+"&t="+new Date().getTime(),
            success: function(response)
            {
            },
            error: function(e)
            {
                alert('Error: ' + e);
            }
    });
}

它尝试在 Spring 中调用以下方法。

@RequestMapping(value=("ajax/UpdateUserRole"), method=RequestMethod.PUT)
public @ResponseBody void updateUserRole(@RequestParam(value=("id")) String id)
{
    System.out.println("id = "+id);
}

FireFox 响应以下错误。

HTTP 状态 405 - 不支持请求方法“GET”

类型状态报告

不支持消息请求方法“GET”

描述 请求的资源不允许指定的 HTTP 方法（不支持请求方法“GET”）。

Apache Tomcat/6.0.26

它与GETandPOST方法一起使用，JSON（与 Jackson-2.1.1 一起）在应用程序的其他部分也可以正常工作。

如需查看dispatcher-servlet.xml文件，完整内容如下。

如何制作除 Spring 3.2 之外的 HTTP 方法GET并POST在 Spring 3.2 中工作？

除非只使用路径参数，否则处理常规 HTTP PUT 需要更多工作。

从Spring 3.1 开始，HttpPutFormContentFilter可用于@RequestParam为application/x-www-form-urlencoded数据工作：

ServletRequest.getParameter*()在 HTTP PUT 请求期间通过一系列方法使表单编码数据可用的过滤器。

Servlet 规范要求表单数据可用于 HTTP POST，但不能用于 HTTP PUT 请求。此过滤器拦截内容类型为“ application/x-www-form-urlencoded”的 HTTP PUT 请求，从请求正文中读取表单编码的内容，并包装 ServletRequest 以使表单数据可用作请求参数，就像它用于 HTTP POST 请求一样。

然而：这个过滤器消耗了请求的输入流，使得它对转换器不可用，比如FormHttpMessageConverter, like used for @RequestBody MultiValueMap<String, String>or HttpEntity<MultiValueMap<String, String>>。因此，一旦您在应用程序中配置了上述过滤器，当调用使用其他转换器的方法时，您将收到“IOException：流已关闭”，这些转换器也需要原始application/x-www-form-urlencodedPUT 数据。


或者，可以使用or手动完成所有操作：@RequestBodyHttpEntity<?>

@RequestMapping(value="ajax/UpdateUserRole", method=RequestMethod.PUT,
    produces = MediaType.TEXT_PLAIN_VALUE)
public @ResponseBody String updateUserRole(
    @RequestBody final MultiValueMap<String, String> data,
    final HttpServletResponse response) {
  Map<String, String> params = data.toSingleValueMap();
  String id = params.get("id");
  String a = params.get("a");
  String b = params.get("b");
  if(id == null || a == null || b == null) {
    response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
    return null;
  }
  return "id = " + id;
}

另请参阅使用或使用的示例：WebDataBinder

public ResponseEntity<String> updateUserRole(
    final HttpEntity<MultiValueMap<String, String>> entity) {
  Map<String, String> params = entity.getBody().toSingleValueMap();
  String id = params.get("id");
  ...

请注意，对于测试，使用MockMvc mockMvc.perform(put(url).param(name, value))实际上也可以处理问题中的代码，即使它在 servlet 容器中会失败。但是 MockMvc 并没有在这样的 servlet 容器中运行，因此有点愚弄你。

MockMvc.param(name, value)也可以很好地与HttpPutFormContentFilter. 但是在使用 MockMvc 测试@RequestBodyor时HttpEntity<?>，还需要application/x-www-form-urlencoded手动创建任何 PUT 内容。喜欢：

mockMvc.perform(put(url).content("id=" + URLEncoder.encode(id, "UTF-8")
  + "&a=" + URLEncoder.encode(a, "UTF-8") + "&b=" + ...)

为了能够简单地使用.param(name, value)，就像 GET 和 POST 一样，可以定义：

public static RequestPostProcessor convertParameters() {
  return new RequestPostProcessor() {
    @Override
    public MockHttpServletRequest postProcessRequest(
        final MockHttpServletRequest request) {
      if ("PUT".equalsIgnoreCase(request.getMethod()) {
        Map<String, String[]> params = request.getParameterMap();
        if (params != null) {
          StringBuilder content = new StringBuilder();
          for (Entry<String, String[]> es : params.entrySet()) {
            for (String value : es.getValue()) {
              try {
                content.append(URLEncoder.encode(es.getKey(), "UTF-8"))
                  .append("=")
                  .append(URLEncoder.encode(value, "UTF-8"))
                  .append("&");
              }
              catch (UnsupportedEncodingException e) {
                throw new IllegalArgumentException("UTF-8 not supported");
              }
            }
          }
          request.setParameters(new HashMap<String, String[]>());
          request.setContent(content.toString().getBytes());
          request.setContentType(MediaType.APPLICATION_FORM_URLENCODED_VALUE);
        }
      }
      return request;
    }
  };
}

...然后.with(convertParameters())在旁边使用.param(name, value)：

mockMvc.perform(put(url)
    .with(convertParameters())
    .param("id", id).param("a", a).param("b", b) ...)

综上所述，简单地使用HttpPutFormContentFilter数据application/x-www-form-urlencoded确实让生活更轻松。

当浏览器发送的不是application/x-www-form-urlencoded数据，而是 JSON 等数据时，尝试映射到MultiValueMap将产生 415 Unsupported Media Type。相反，使用类似@RequestBody MyDTO data或HttpEntity<MyDTO> entity如Parsing JSON in Spring MVC using Jackson JSON中所述的内容。
