二.application.yml
#fastdfs 配置
fdfs:
so-timeout: 150000
connect-timeout: 150000 #超时时间
thumb-image:
width: 150
height: 150
tracker-list:
- 111.111.111.111:22122 #ip:端口号
spring:
thymeleaf:
prefix: classpath:/templates/
servlet:
multipart:
max-file-size: 50MB #单次单个文件最大大小
max-request-size: 50MB #单次上传所有文件的总大小<br> #注意,这里springboot默认配置的大小是1MB和10MB,可能不够用,具体参考MultipartProperties.java
三.FastUtil.java 前提先将Nginx和FastDFS整合
@Component public class FastUtil { private final Logger logger = LoggerFactory.getLogger(FastUtil.class); @Autowired private FastFileStorageClient fastFileStorageClient; /** * 文件上传 * 最后返回fastDFS中的文件名称; * * @param bytes 文件字节 * @param fileSize 文件大小 * @param extension 文件扩展名 * @return fastDfs路径 */ public String uploadFile(byte[] bytes, long fileSize, String extension) { ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes); StorePath storePath = fastFileStorageClient.uploadFile(byteArrayInputStream, fileSize, extension, null); return "http://111.111.111.111/"+storePath.getFullPath(); } public byte[] downloadFile(String group,String path) throws IOException { DownloadByteArray downloadByteArray = new DownloadByteArray(); byte[] bytes = fastFileStorageClient.downloadFile(group, path, downloadByteArray); return bytes; } }
四.配置类 FdfsConfig.java
@Configuration @Import(FdfsClientConfig.class) @EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING) public class FdfsConfig { }
五.Controller
@RestController public class FdfsController { @Autowired private FastUtil fastDFSClientWrapper; private final Logger logger = LoggerFactory.getLogger(FdfsController.class); @PostMapping("/upload") @ResponseBody public String upload(MultipartFile file) throws Exception { byte[] bytes = new byte[0]; try { bytes = file.getBytes(); } catch (IOException e) { logger.error("获取文件错误"); e.printStackTrace(); } //获取源文件名称 String originalFileName = file.getOriginalFilename(); //获取文件后缀--.doc String extension = originalFileName.substring(originalFileName.lastIndexOf(".") + 1); String fileName = file.getName(); //获取文件大小 long fileSize = file.getSize(); System.out.println(originalFileName + "==" + fileName + "==" + fileSize + "==" + extension + "==" + bytes.length); String string = fastDFSClientWrapper.uploadFile(bytes, fileSize, extension); return string; } }
六.前端页面 index.html
<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3"> <head> <meta charset="UTF-8" /> <title>Insert title here</title> </head> <body> <h2 th:inlines="text">文件上传</h2> <form action="upload" method="post" enctype="multipart/form-data"> <p>选择文件: <input type="file" name="file"/></p> <p><input type="submit" value="提交"/></p> </form> </body> </html>
七.开始上传
最后在页面上返回一个URL,可以直接访问
