SpringBoot实现单文件上传
人气:0SpringBoot实现单文件上传功能,供大家参考,具体内容如下
架构为springboot+thymeleaf,采用ajax方式提交
1. 页面testFile.html
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>测试文件上传</title> <script src="../static/jquery/jquery-2.1.1.min.js" th:src="@{/jquery/jquery-2.1.1.min.js}"></script> <script type="text/javascript"> $(function () { $("#upload1").click(function () { var formData = new FormData(); formData.append("file", document.getElementById("file").files[0]); $.ajax({ url: "/file/upload1", type: "POST", data: formData, //必须false才会自动加上正确的Content-Type contentType: false, //必须false才会避开jquery对 formdata 的默认处理 //XMLHttpRequest会对 formdata 进行正确的处理 processData: false, success: function (data) { if (data.status == "true") { alert("上传成功!"); } if (data.status == "error") { alert(data.msg); } }, error: function () { alert("上传失败!"); } }); }); }); </script> </head> <body> <form method="POST" enctype="multipart/form-data" action="/file/upload1"> <fieldset> <legend>单一文件上传实例:</legend> 文件1:<input type="file" name="file" id="file"/><br/> <input type="button" id="upload1" value="上传"/><br/> </fieldset> </form> </body> </html>
2. FileController.java
package com.stormkai.controller; import java.io.File; import java.io.IOException; import java.util.HashMap; import java.util.Map; import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.multipart.MultipartFile; import lombok.extern.slf4j.Slf4j; @Controller @RequestMapping("/file") @Slf4j public class FileController { @GetMapping("/index") public String index() { return "testFile"; } @PostMapping("/upload1") @ResponseBody public Map<String, Object> upload1(@RequestParam("file") MultipartFile file, HttpServletRequest request) throws IOException { log.info("系统路径={}",request.getSession().getServletContext().getRealPath("")); String path = "F:\\uploadfile\\"; if(!new File(path).exists()){ new File(path).mkdirs(); } file.transferTo(new File(path + file.getOriginalFilename())); Map<String, Object> result = new HashMap<>(); result.put("status", "true"); result.put("data", null); return result; } }
