使用 AJAX 和 Spring Boot 从磁盘中删除文件

Question

我正在尝试使用 Ajax 和 Spring 引导技术从磁盘（本地或服务器）中删除文件。

到目前为止，我已经尝试过：

Ajax/jquery：

            $(".ct-color-specs").on("click",".color-spec-file-delete",function() {
                    var deletedFileName = $(this).parents(".ct-attached-color-spec-files").find("a").text();
                    $.ajax({

                        url : "/Application/removeFile/"+deletedFileName",
                        type: 'DELETE',  
                        success: function (res) {  
                            console.log(data);
                        } 
                    });
                });

控制器：

 @RequestMapping(value = "/removeFile",produces="text/html", method = RequestMethod.DELETE)
    public String removeFileHandler(@PathVariable("deletedFileName") String filepath, Model model) {
        String removeFileCheck = "false";
        try{

            System.out.println("Delete filepath from AJX");
            File file = new File(filepath);

            if(file.delete()){
                System.out.println(file.getName() + " is deleted!");
                removeFileCheck="true";
            }else{
                System.out.println("Delete operation is failed.");
            }

        }catch(Exception e){

            e.printStackTrace();

        }
        model.addAttribute("checkList", removeFileCheck);
        return "p/view";
    }

错误：

“未找到”消息：“没有可用消息”路径： “/Application/removeFile/File.pdf”状态：404

Answer 1

您以错误的格式编写了@RequestMapping(value = "/removeFile" ...)

spring 中的路径变量如下所示

@RequestMapping(value="/user/{userId}/roles/{roleId}",method = RequestMethod.GET)
     public String getLogin(@PathVariable("userId") String userId,
         @PathVariable("roleId") String roleId){
         System.out.println("User Id : " + userId);
         System.out.println("Role Id : " + roleId);
         return "hello";
     }

Answer 2

我将在这里写答案，因为我已经用下面的代码解决了。

控制器：

@RequestMapping(value = "/removeFile/{deletedFileName}", method = RequestMethod.GET)
public String removeFileHandler(@PathVariable("deletedFileName") String filepath, Model model) {
       .....
    }

AJAX/jquery：

            $(".ct-color-specs").on("click",".color-spec-file-delete",function() {
                    var deletedFileName = $(this).parents(".ct-attached-color-spec-files").find("a").text().split('/').pop().split('\\').pop();;
                    alert("deletedFileName--->" + deletedFileName);
                     $.ajax({
                        url : "/Application/removeFile/"+deletedFileName,
                        type: 'GET',  
                        success: function (res) {  
                            console.log(data);
                        } 
                    });
                });
