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> <h1 th:inlines="text">文件上传</h1> <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
