Jersey 409

Jersey 报409错误 解决方案 ： 在webapp下新建upload文件夹 然后建一个file空文件 像这样：

Controller层：

package com.xiepanpan.ecps.controller;

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.WebResource;
import com.xiepanpan.ecps.utils.ECPSUtils;
import net.sf.json.JSONObject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.MultipartHttpServletRequest;

import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.io.PrintWriter;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Iterator;
import java.util.Random;


/**
 * describe:图片上传

 * @author xiepanpan
 * @date 2018/10/31
 */
@Controller
@RequestMapping("/upload")
public class EbUploadController {

    @RequestMapping("/uploadPic.do")
    public void uploadPic(HttpServletRequest request, PrintWriter printWriter) throws IOException {
        MultipartHttpServletRequest mr = (MultipartHttpServletRequest) request;
        //从表单中获取文件
        Iterator<String> iter = mr.getFileNames();
        String inputName = iter.next();
        // 获取文件
        MultipartFile multipartFile = mr.getFile(inputName);
        byte[] bytes = multipartFile.getBytes();
        //定义上传文件的文件名
        String fileName = new SimpleDateFormat("yyyyMMddHHmmssSSS").format(new Date());
        Random random = new Random();
        //文件名后三位为随机数
        for (int i=0;i<3;i  ){
            fileName=fileName random.nextInt(10);
        }
        //获得后缀名
        String originalFilename = multipartFile.getOriginalFilename();
        String suffix = originalFilename.substring(originalFilename.lastIndexOf("."));
        //相对路径保存到数据库中 绝对路径显示缩略图
        //要上传的绝对路径
        String relativePath="/upload/"   fileName   suffix;
        String realPath = ECPSUtils.readProp("upload_file_path")   relativePath;

        //创建Jersey客户端
        Client client = Client.create();
        //指定上传的绝对路径
        WebResource webResource = client.resource(realPath);
        webResource.put(bytes);
        JSONObject jsonObject = new JSONObject();
        jsonObject.accumulate("realPath",realPath);
        jsonObject.accumulate("relativePath",relativePath);
        String result = jsonObject.toString();
        printWriter.write(result);

    }

}

ECPSUtil工具类：

package com.xiepanpan.ecps.utils;

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

/**
 * describe:

 * @author xiepanpan
 * @date 2018/11/01
 */
public class ECPSUtils {

    /**
     * 读取配置文件
     * @param key
     * @return
     */
    public static String readProp(String key) {
        InputStream inputStream = ECPSUtils.class.getClassLoader()
                .getResourceAsStream("ecps_prop.properties");
        Properties properties = new Properties();
        String value= null;
        try {
            properties.load(inputStream);
            value= properties.getProperty(key);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return value;
    }
}

配置文件：

upload_file_path=http://localhost:8092/ecps-file
