今天在某音熱門視頻中刷到的萨惑，圖片轉(zhuǎn)ASCLL碼的視頻，抱著試試看的態(tài)度我使用Spring Boot做了一個簡易web版的贞滨。修為尚淺入热，請多指教！廢話少說晓铆，上代碼。

第二步 配置文件

server.port=80

## OSS
#OSS配置
oss.endpoint=你的endPoint(見控制臺)
oss.keyid= 你的keyid
oss.keysecre=你的keysecret
oss.bucketname1=你新建的bucket的名字
oss.filehost=你的目錄我做測試的是file(就是一個根目錄)

第三步 編寫配置文件ConsantConfig.java

package com.zuoyang.image2ascll.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

/**
 * @author  左羊

 */
@Component("constantConfig")
public class ConstantConfig {
    @Value("${oss.endpoint}")
    private String LXIMAGE_END_POINT;
    @Value("${oss.keyid}")
    private String LXIMAGE_ACCESS_KEY_ID;
    @Value("${oss.keysecre}")
    private String LXIMAGE_ACCESS_KEY_SECRET;
    @Value("${oss.filehost}")
    private String LXIMAGE_FILE_HOST;
    @Value("${oss.bucketname1}")
    private String LXIMAGE_BUCKET_NAME1;

    public String getLXIMAGE_END_POINT() {
        return LXIMAGE_END_POINT;
    }

    public void setLXIMAGE_END_POINT(String LXIMAGE_END_POINT) {
        this.LXIMAGE_END_POINT = LXIMAGE_END_POINT;
    }

    public String getLXIMAGE_ACCESS_KEY_ID() {
        return LXIMAGE_ACCESS_KEY_ID;
    }

    public void setLXIMAGE_ACCESS_KEY_ID(String LXIMAGE_ACCESS_KEY_ID) {
        this.LXIMAGE_ACCESS_KEY_ID = LXIMAGE_ACCESS_KEY_ID;
    }

    public String getLXIMAGE_ACCESS_KEY_SECRET() {
        return LXIMAGE_ACCESS_KEY_SECRET;
    }

    public void setLXIMAGE_ACCESS_KEY_SECRET(String LXIMAGE_ACCESS_KEY_SECRET) {
        this.LXIMAGE_ACCESS_KEY_SECRET = LXIMAGE_ACCESS_KEY_SECRET;
    }

    public String getLXIMAGE_FILE_HOST() {
        return LXIMAGE_FILE_HOST;
    }

    public void setLXIMAGE_FILE_HOST(String LXIMAGE_FILE_HOST) {
        this.LXIMAGE_FILE_HOST = LXIMAGE_FILE_HOST;
    }

    public String getLXIMAGE_BUCKET_NAME1() {
        return LXIMAGE_BUCKET_NAME1;
    }

    public void setLXIMAGE_BUCKET_NAME1(String LXIMAGE_BUCKET_NAME1) {
        this.LXIMAGE_BUCKET_NAME1 = LXIMAGE_BUCKET_NAME1;
    }
}

            e.printStackTrace();
        }

}

第七步 Service層

接口類

package com.zuoyang.image2ascll.service;

/**
 * @author  左羊
 * @date 2019-07-31 11:53:24
 */
public interface ImageToAscllServie {
    String imageToAscll(String path);
}

實現(xiàn)類

package com.zuoyang.image2ascll.service.imp;

import com.zuoyang.image2ascll.service.ImageToAscllServie;
import com.zuoyang.image2ascll.util.ImageToAscll;
import com.zuoyang.image2ascll.util.ImageHelper;
import org.springframework.stereotype.Service;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;

/**
 * @author  左羊
 * @date 2019-07-31 11:53:24
 */
@Service
public class ImageToAscllServiceImp implements ImageToAscllServie {
    @Override
    public String imageToAscll(String path) {
        InputStream in = null;
        //縮放后需要保存的路徑
        File saveFile = new File("/data/image2ascll/txts/ABC.jpg");
        try {
            //原圖片的路徑
            in = new FileInputStream(new File("/data/image2ascll/txts/"+path));
            if(ImageHelper.compress(in, saveFile, 5)){
                System.out.println("圖片壓縮5倍掌实！");
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                in.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

       return ImageToAscll.createAsciiPic("/data/image2ascll/txts/ABC.jpg");
    }
}

第八步 controller層

IndexController.class

package com.zuoyang.image2ascll.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @author  左羊
 * @date 2019-07-31 11:53:24
 */
@Controller
public class IndexController {

    @RequestMapping("/")
    public String index()
    {
        return "imageToAscll";
    }
}

ImageToAscllController.class

package com.zuoyang.image2ascll.controller;

import com.zuoyang.image2ascll.service.imp.ImageToAscllServiceImp;
import com.zuoyang.image2ascll.util.AliyunOssUtil;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.http.HttpServletRequest;
import java.io.File;
import java.io.FileOutputStream;
/**
 * @author  douxiaofeng

 */

@RestController
public class ImageToAscllController {
    private final org.slf4j.Logger logger = LoggerFactory.getLogger(getClass());
    @Autowired
    private ImageToAscllServiceImp imageToAscllServiceImp;
    @Autowired
    private AliyunOssUtil aliyunOSSUtil;

    @RequestMapping(value = "/uploadimg")
    @PostMapping
    public @ResponseBody
    String imgUploa(@RequestParam("file") MultipartFile file, HttpServletRequest request) {
        logger.info("文件上傳");
        String filename = file.getOriginalFilename();
        logger.info("文件路徑 = {}",filename);

        String uploadUrl = null;
        String uploadTxtUrl = null;
        String txtName = null;
        try {
            if (file != null) {
                if (!"".equals(filename.trim())) {
                    // 圖片
                    File newFile = new File("/data/image2ascll/txts/"+filename);
                    FileOutputStream os = new FileOutputStream(newFile);
                    os.write(file.getBytes());
                    os.close();
                    file.transferTo(newFile);
                    // 圖片上傳到OSS
                    uploadUrl = file.getOriginalFilename();
                    logger.info("圖片地址={}",uploadUrl);
                    // 文字
                     txtName = imageToAscllServiceImp.imageToAscll(uploadUrl);
                    File newTxtFile = new File(txtName);
                    // 上傳到OSS
                    uploadTxtUrl = aliyunOSSUtil.upLoad(newTxtFile);

                }
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return uploadTxtUrl;
    }
}

啟動類

package com.zuoyang.image2ascll;

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

/**
 * @author  左羊
 * @date 2019-07-31 11:53:24
 */
@SpringBootApplication
public class Image2ascllApplication {

    public static void main(String[] args) {
        SpringApplication.run(Image2ascllApplication.class, args);
    }

}
