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
　　#注意，这里springboot默认配置的大小是1MB和10Mhttp://B，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

xmlns:sec="http://thymeleaf.org/thymeleaf-extras-saRRMbuOfuPpringsecurity3">

选择文件:

七.开始上传

最后在页面上返回一个URL，可以直接访问
