package com.llh.controller;
import java.io.File;
import java.io.IOException;
import java.util.Date;
import java.util.List;
import java.util.Random;
import javax.annotation.Resource;

import net.sf.json.JSONArray;
@Controller
@Scope("prototype")
public class StudentController {
@Resource
private StudentService studentService;
/**

*
* @param pageCode

* @return
*/
@RequestMapping(value = "selectAll", produces = "text/html;charset=utf-8")
public @ResponseBody String selectAll(int pageCode, int pageSize) {
PageHelper.startPage(pageCode, pageSize);
List<Student> slist = studentService.selectAll();

String path = request.getServletContext().getRealPath("/upload/");// 上传保存的路径
String fileName = changeName(name);
String rappendix = "upload/" + fileName;

}
public static String changeName(String oldName) {
Random r = new Random();
Date d = new Date();

}
/**

*/

System.out.println("编辑");
Student s = studentService.selectByPrimaryKey(stuid);
JSONArray json = JSONArray.fromObject(s);
String js = json.toString();
System.out.println(js);
return js;
}
/**

*
* @param stuid
* @param stuname
* @return
*/
@RequestMapping(value = "updateBystuid", produces = "text/html;charset=utf-8")
public @ResponseBody String updateBystuid(@ModelAttribute Student s) {
System.out.println("修改中");
System.out.println(s.getStuname() + s.getStuid()+s.getUserimage());
int a = studentService.updateByPrimaryKey(s);
if (a != 0) {
return "ok";
}
return "error";
}
/**
* 下载
*
* @param stuid
* @return
* @throws IOException
*/
@RequestMapping(value = "download", produces = "text/html;charset=utf-8")
public ResponseEntity<byte[]> download(Integer stuid,HttpServletRequest request) throws IOException {
Student s = studentService.selectByPrimaryKey(stuid);
String path=request.getServletContext().getRealPath("\\");
String downpath = path+s.getUserimage();
File file1=new File(downpath);
//String downloadFileName=new String(downpath.getBytes("UTF-8"),"iso-8859-1");
HttpHeaders heads=new HttpHeaders();
heads.setContentDispositionFormData("attachment", downpath);
heads.setContentType(MediaType.APPLICATION_OCTET_STREAM);
return new ResponseEntity<byte[]>(FileUtils.readFileToByteArray(file1), heads,HttpStatus.CREATED);
}
}三、dao层和service层实体类就掠过了
这里使用到的有自动生成实体类，Maven的分页
