拦截器：
public class SuperAction extends ActionSupport implements ServletRequestAware,ServletResponseAware,ServletContextAware{
private static final long serialVersionUID = 1L;
protected HttpServletRequest request;
protected HttpServletResponse response;
protected HttpSession session;
protected ServletContext application;
@Override
public void setServletContext(ServletContext application) {
this.application=application;
}
@Override
public void setServletResponse(HttpServletResponse response) {
this.response=response;
}
@Override
public void setServletRequest(HttpServletRequest request) {
this.request=request;
this.session=this.request.getSession();
}
}
模型驱动方式获取user数据
public class UsersAction extends SuperAction implements ModelDriven<Users> {
private static final long serialVersionUID = 1L;
private Users user =new Users();
@Override
public Users getModel() {
return this.user;
}
// 用户登录动作
public String login() {
UsersDao userDao = new UsersDaoImpl();
if(this.user!=null){
if (userDao.userLogin(this.user)) {
return "login_success";
} else {
return "login_failure";
}
}
return "login_failure";
}
}
user:
public class Users {
private int userId;
private String userName;
private String realName;
private String userPwd;
private String tel;
private String mark;
private Date regTime;
private Date updateTime;
.......省略getter和setter
配置
<package name="users" namespace="/" extends="default">
<action name="*_*" class="action.{1}Action" method="{2}">
<result name="login_success">/index.jsp</result>
<result name="login_failure">/login.jsp</result>
<result name="reg_success">/login.jsp</result>
<result name="reg_failure">/reg.jsp</result>
</action>
</package>
jsp页面在根路径：
表单：
<form action="<%=path%>/Users_login.action" method="post" id="login">
<label class="label1"> <span class="lab1"></span> <input
type="text" id="name" name="name" maxlength="20"
placeholder="请输入您的用户名"/>
</label>
<!-- name error tip begin-->
<label class="label2"> <span class="lab2"></span> <input
type="password" name="pwd" id="pwd" maxlength="20"
placeholder="请输入您的密码" />
</label>
<!-- password error tip begin-->
<input type="submit" value="" id="sub" />
</form>
你把jsp中的name换成user.username , pwd换成user.userpwd
