更新数据时报错500

Question

我想更新 table 名称广告中的属性 ad_stat，但出现错误：

  500 Could not parse multipart servlet request; nested exception is javax.servlet.ServletException:org.apache.tomcat.util.http.fileupload.FileUploadBase$InvalidContentTypeException: the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is null"

这里是更新数据的代码

@ApiOperation(value = "deactiveAd", nickname = "deactive Ad")
@RequestMapping(method = RequestMethod.GET, path = "ads/deactive", produces 
= "application/json")
@ApiResponses(value = {
            @ApiResponse(code = 200, message = "Success"),
            @ApiResponse(code = 401, message = "Unauthorized"),
            @ApiResponse(code = 403, message = "Forbidden"),
            @ApiResponse(code = 404, message = "Not Found"),
            @ApiResponse(code = 500, message = "Failure")
    })
    public Response deactiveAd(@RequestPart(name = "adsId", required = true) 
int ad_id){
            Response response = new Response();
            DbHandler db = new DbHandler();
            if(db.getResult() == 0){
                    try{
                            String sql = "UPDATE advert SET ad_stat = false 
WHERE ad_id = "+ad_id+";";
                            if(!db.execute(sql)) {
                            response.setStatus("0");
                    }else{
                            response.setStatus("3");
                    }
                            db.closeStatement();
                            db.closeConnection();
                    }catch(SQLException e) {
                            response.setStatus("1");
                    try{
                            db.closeConnection();
                            db.closeStatement();
                    }catch(SQLException e1) {

                    }
                    }
            }else{
            response.setStatus(String.valueOf(db.getResult()));
    }
    return response;
}

ad_stat 的数据类型是布尔值，我试图伪造它

Answer 1

改变

@RequestMapping(method = RequestMethod.GET, path = "ads/deactive", produces = "application/json")

至

@RequestMapping(method = RequestMethod.POST, path = "ads/deactive", produces = "application/json",Content-Type="multipart/formdata")

Answer 2

将 enctype 添加到您的表单。

<form enctype=”multipart/form-data”></form>
