使用頭像上傳功能完成註冊
Controller層程式碼
public String ZC(String name, String phone, String username, String pwd, MultipartFile file)
throws IllegalStateException, IOException {
// 定義儲存資料庫的路徑
String sqlpath = null;
// 定義檔案儲存的本地路徑
String localPath = "D:\\xxx\\SSMDemo\\WebContent\\images\\" domain實體類
package com.mvaweb.domain;
import org.springframework.web.multipart.MultipartFile;
public class VIP {
public int id;
public String name;
public String phone;
public String username;
public String pwd;
public String tx;//資料庫中的路徑
public MultipartFile file;//實際儲存的檔案
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
public String getTx() {
return tx;
}
public void setTx(String tx) {
this.tx = tx;
}
public MultipartFile getFile() {
return file;
}
public void setFile(MultipartFile file) {
this.file = file;
}
public VIP() {
// TODO Auto-generated constructor stub
}
public VIP(int id, String name, String phone, String username, String pwd, String tx) {
super();
this.id = id;
this.name = name;
this.phone = phone;
this.username = username;
this.pwd = pwd;
this.tx = tx;
}
}
登入功能實現頭像展示
@Autowired
private LoginServiceImpl LoginServiceImpl;
@RequestMapping("/login")
public String login(String username, String pwd, HttpServletRequest req, HttpSession session) {
ModelAndView mav = new ModelAndView();
VIP vip = LoginServiceImpl.login(username);
//System.out.println(vip.getTx());
if (vip == null) {
return "使用者名稱不正確";
} else if (!vip.getPwd().equals(pwd)) {
return "密碼不正確";
} else {
session.setAttribute("username", username);
session.setAttribute("vip", vip.getTx());
return "loginsuccess";
}
}
jsp頁面獲取使用者名稱和頭像資訊
<body>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path;
System.out.println(basePath);
%>
<h3>歡迎使用本系統</h3>
<div class="imgs">
<img src="<%=basePath%>${vip}">
</div>
使用者名稱：${username}
</body>
