controller的编写

package com.test.cn.controller; import java.io.File; import java.io.IOException; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import javax.servlet.http.HttpServletRequest; import org.apache.commons.io.FileUtils; import org.springframework.http.HttpHeaders; import org.springframework.http.HttpStatus; import org.springframework.http.MediaType; import org.springframework.http.ResponseEntity; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.multipart.MultipartFile; import com.test.cn.entity.User; @Controller @RequestMapping("/user") public class UserController { private final static Map<String, User> users = new HashMap<String, User>(); // 模拟数据源,构造初始数据 public UserController() { users.put("张起灵", new User("张起灵", "闷油瓶", "02200059", "menyouping@yeah.net")); users.put("李寻欢", new User("李寻欢", "李探花", "08866659", "lixunhuan@gulong.cn")); users.put("拓拔野", new User("拓拔野", "搜神记", "05577759", "tuobaye@manhuang.cc")); users.put("孙悟空", new User("孙悟空", "美猴王", "03311159", "sunhouzi@xiyouji.zh")); } @RequestMapping("/list") public String list(Model model) { model.addAttribute("users", users); return "list"; } @RequestMapping(value = "/add", method = RequestMethod.GET) public String addUser() { return "index"; } @RequestMapping(value = "/add", method = RequestMethod.POST) public String addUser(User user, @RequestParam MultipartFile[] myfiles, HttpServletRequest request) throws IOException { // 如果只是上传一个文件，则只需要MultipartFile类型接收文件即可，而且无需显式指定@RequestParam注解 // 如果想上传多个文件，那么这里就要用MultipartFile[]类型来接收文件，并且还要指定@RequestParam注解 // 并且上传多个文件时，前台表单中的所有<input // type="file"/>的name都应该是myfiles，否则参数里的myfiles无法获取到所有上传的文件 for (MultipartFile myfile : myfiles) { if (myfile.isEmpty()) { System.out.println("文件未上传"); } else { System.out.println("文件长度: " + myfile.getSize()); System.out.println("文件类型: " + myfile.getContentType()); System.out.println("文件名称: " + myfile.getName()); System.out.println("文件原名: " + myfile.getOriginalFilename()); System.out.println("========================================"); // 如果用的是Tomcat服务器，则文件会上传到\\%TOMCAT_HOME%\\webapps\\YourWebProject\\WEB-INF\\upload\\文件夹中 String realPath = request.getSession().getServletContext() .getRealPath("/WEB-INF/upload"); // 这里不必处理IO流关闭的问题，因为FileUtils.copyInputStreamToFile()方法内部会自动把用到的IO流关掉 FileUtils.copyInputStreamToFile(myfile.getInputStream(), new File(realPath, myfile.getOriginalFilename())); } } users.put(user.getUsername(), user); return "redirect:/user/list"; } @RequestMapping("/download") public ResponseEntity<byte[]> download(String filename, File file, HttpServletRequest request) throws IOException { // String filename = "电子商务通讯录.xlsx"; // String realPath = request.getSession().getServletContext() // .getRealPath("/WEB-INF/upload/电子商务通讯录.xlsx"); // File file = new File(realPath); String dfilename = new String(filename.getBytes("gb2312"), "iso-8859-1"); HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_OCTET_STREAM); headers.setContentDispositionFormData("attachment", dfilename); ResponseEntity<byte[]> entity = new ResponseEntity<byte[]>( FileUtils.readFileToByteArray(file), headers, HttpStatus.CREATED); return entity; } @RequestMapping(value = "ajaxTest") @ResponseBody public List<String> ajaxTest(String name, String url) { System.out.println(name + "--" + url); List<String> list = new ArrayList<String>(); list.add(name); list.add(url); return list; } @RequestMapping(value = "ajaxTest1") @ResponseBody public List<String> ajaxTest1(@RequestBody List<User> users) { System.out.println("后台数据---------------------------"); System.out.println(users.get(0).getUsername()+"--"+users.get(0).getPassword()); ArrayList<String> list = new ArrayList<String>(); for (User u : users) { list.add(u.getUsername()); list.add(u.getPassword()); } return list; } }

user.java的编写

package com.test.cn.entity; public class User { private String username; private String nickname; private String password; private String email; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getNickname() { return nickname; } public void setNickname(String nickname) { this.nickname = nickname; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public User() { } public User(String username, String nickname, String password, String email) { this.username = username; this.nickname = nickname; this.password = password; this.email = email; } }
