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：
代码语言：javascript复制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;
/**

*/
@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：
代码语言：javascript复制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：
