# 分布式文件系统FDFS配置
fdfs:
  soTimeout: 1500 #socket连接超时时长
  connectTimeout: 600 #连接tracker服务器超时时长
  resHost: 192.168.25.133
  storagePort: 80
  thumbImage: #缩略图生成参数，可选
      width: 150
      height: 150
  trackerList: #TrackerList参数,支持多个，我这里只有一个，如果有多个在下方加- x.x.x.x:port
    - 192.168.25.133:22122
spring:
  http:
    multipart:
      max-file-size: 100MB # 最大支持文件大小
      max-request-size: 100MB # 最大支持请求大小

启动类:

package com.cxy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class FastdfsApplication {

    public static void main(String[] args) {
        SpringApplication.run(FastdfsApplication.class, args);
    }

}

结果类:

package com.cxy.bean;

public class Result<T> {
    public Result(){} ;
     
    public static <T> Result<T> createResult(){
        return new Result<T>() ;
    }
 
 
    private T content;
    private int code;
    private String message ;
 
    public T getContent() {
        return content;
    }
 
    public Result<T> setContent(T content) {
        this.content = content;
        return this ;
    }
 
    public int getCode() {
        return code;
    }
 
    public Result<T> setCode(int code) {
        this.code = code;
        return this ;
    }
 
    public String getMessage() {
        return message;
    }
 
    public Result<T> setMessage(String message) {
        this.message = message;
        return this ;
    }


}

api测试类:

package com.cxy.bean;

import java.util.HashMap;
import java.util.Map;

import javax.annotation.Resource;

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import com.alibaba.fastjson.JSONObject;
import com.alibaba.fastjson.serializer.SerializerFeature;
@RestController
public class TestApi {

    
    @Resource
    private FastDFSClientWrapper fwc;
    
    /**
     * 图片上传
     * @param file
     * @return
     *
     * @author ZHANGJL
     * @dateTime 2018-02-24 15:49:48
     */
    @PostMapping("/uploadPic")
    public @ResponseBody String uploadPic(@RequestParam("file")MultipartFile file){
        Result<Map<String, String>> result = new Result<Map<String,String>>();
        try {
            Map<String, String> map = new HashMap<String, String>();
            //返回FastDFS配置好的图片路径
            String url = fwc.uploadFile(file);//正常上传
            String url1 = fwc.uploadImageAndCrtThumbImage(file);//小图
            map.put("max", url);
            map.put("min", url1);
            result.setCode(200);
            result.setContent(map);
        } catch (Exception e) {
            // TODO: handle exception
            
            result.setCode(400);
        }
        
        return JSONObject.toJSONString(result, SerializerFeature.WriteMapNullValue);
    }

}

postman测试:

将地址拼接:

就可以看如下结果.,

这个也可以为单独的文件上传服务,
