springboot 上传文件 thymeleaf

本文主要说的是springboot使用thymeleaf上传文件

pom.xml依赖

  <!--web项目-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

	    <!--引入thymeleaf的依赖-->
	    <dependency>
		    <groupId>org.springframework.boot</groupId>
		    <artifactId>spring-boot-starter-thymeleaf</artifactId>
	    </dependency>

application.properties配置

#默认路径
spring.thymeleaf.prefix=classpath:/templates/thymeleaf/
#后缀
spring.thymeleaf.suffix=.html
#模板格式
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
spring.thymeleaf.cache=false

前端代码编写

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>上传文件</title>
</head>
<body>
<form method="POST" enctype="multipart/form-data" action="/upload">
	<p>
		文件：<input type="file" name="file">
	</p>
	<p>
		<input type="submit" value="上传">
	</p>
</form>
</body>
</html>

文件需要在resources下面的templates文件夹下
在这里插入图片描述
4. controller编写

package com.study.cdmy.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;

import java.io.File;
import java.io.IOException;

@Controller
public class UploadController {

	private static final Logger LOGGER = LoggerFactory.getLogger(UploadController.class);

	@RequestMapping("/goUpload")
	public String upload() {
		return "upload";
	}

	@RequestMapping("/upload")
	@ResponseBody
	public String upload(@RequestParam("file") MultipartFile file) {
		if (file.isEmpty()) {
			return "上传失败，请选择文件";
		}

		String fileName = file.getOriginalFilename();
		String filePath = "D:\\photos\\";
		File dest = new File(filePath + fileName);
		try {
			if (!dest.exists()){
				dest.createNewFile();
			}
			file.transferTo(dest);
			LOGGER.info("上传成功");
			return "上传成功";
		} catch (IOException e) {
			LOGGER.error(e.toString(), e);
		}
		return "上传失败！";
	}
}

启动程序，然后访问 http://127.0.0.1:8080/goUpload

选择文件，进行上传

以上就是上传图片的过程
