ssm项目：找回密码
用的ajax书写的
- Controller层
/**
* 跳转到更新个人密码页面
* Created by gf on 2017年7月19日
*
* @return
*/
@RequestMapping(value="password.do",method=RequestMethod.GET)
public String updatePwdGet(HttpSession session,Model model){
//根据当前用户查询基本信息，然后返回个人中心页面
UserModel user = getCurrentUser(session);
model.addAttribute("user",user);
return "front/user/password";
}
/**
* 提交并更新个人密码
* Created by gf on 2017年7月19日
*
* @return
*/
@RequestMapping(value="password.do",method=RequestMethod.POST)
public @ResponseBody
Object updatePwdPost(UpdatePwdInfo info,Model model,HttpSession session){
UserModel user = getCurrentUser(session);
//判断旧密是否正确，不正确禁止更新
//此处未做数据校验
OperateResult result = userService.updateUserPassword(user.getId(),info);
//判断是否更改成功，根据结果给出不同的提示信息
HashMap map = new HashMap();
if(!result.isSuccess()){
System.out.println(">>>>>重置密码失败："+result.getMessage());
map.put("success", false);
map.put("message", result.getMessage());
return map;
}else{
map.put("success", true);
map.put("message", result.getMessage());
return map;
}
}其中UpdatePwdInfo是封装的一个参数对象，代码如下
/**
* Created By gf on 2017年7月20日
* Descr: 更新密码时提交的信息
*
*/
public class UpdatePwdInfo {
private String oldPassword;
private String newPassword;
private String newPasswordAgain;
public String getOldPassword() {
return oldPassword;
}
public void setOldPassword(String oldPassword) {
this.oldPassword = oldPassword;
}
public String getNewPassword() {
return newPassword;
}
public void setNewPassword(String newPassword) {
this.newPassword = newPassword;
}
public String getNewPasswordAgain() {
return newPasswordAgain;
}
public void setNewPasswordAgain(String newPasswordAgain) {
this.newPasswordAgain = newPasswordAgain;
}
@Override
public String toString() {
return "UpdatePwdInfo [oldPassword=" + oldPassword + ", newPassword=" + newPassword + ", newPasswordAgain="
+ newPasswordAgain + "]";
}
}
OperateResult是封装的结果
/**
* Created By gf on 2017年7月19日
* Descr: 封装操作结果
*
*/
public class OperateResult {
private boolean success;
private String message;
public boolean isSuccess() {
return success;
}
public void setSuccess(boolean success) {
this.success = success;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
@Override
public String toString() {
return "OperateResult [success=" + success + ", message=" + message + "]";
}
}- service层实现类
@Override
public OperateResult updateUserPassword(int id,UpdatePwdInfo info) {
UserModel model = queryUserById(id);
OperateResult result = new OperateResult();
if(model.getPassword().equals(MD5Utils.getMd5Simple(info.getOldPassword()))){
HashMap map = new HashMap();
map.put("id", id);
map.put("pwd", MD5Utils.getMd5Simple(info.getNewPassword()));
mapper.updateUserPwd(map);
result.setSuccess(true);
result.setMessage("更新成功");
}else{
result.setSuccess(false);
result.setMessage("旧密码输入错误");
}
return result;
}- mapper层
public int updateUserPwd(HashMap map);- xml映射文件
<update id="updateUserPwd" parameterType="java.util.HashMap">
update user set password=#{pwd} where id=#{id}
