关于struts2从页面取值的问题
我的页面如下：
<html> <body> <center> <h1>注册新用户</h1> <p>带*的，你懂的！</p> <s:form action="registValidate" method="post" name="regist"> <!-- 加入了Token标记 --> <s:token/> <s:textfield name="username" label="姓名" required="true"/> <s:password name="password" label="密码" required="true"/> <s:password name="confirmPassword" label="确认密码" required="true"/> <s:textfield name="userAge" label="年龄" required="true"/> <s:radio name="userSex" list="#{'男':'男','女':'女'}" label="性别" required="true"/> <s:textfield name="tel" label="电话" required="true" required="true"/> <s:doubleselect label="所在城市" labelposition="top" name="address" list="{'江西','浙江'}" doubleName="city" doubleList="top=='江西'?{'南昌','赣州','九江','新余','南康','上饶'}: {'宁波','杭州','建德','富阳','临安','余姚'}" doubleSize="3" required="true"/> <s:submit value="提交"/> <s:reset value="重置"/> </s:form> </center> </body></html>package bank.action;import bank.domain.UserInfo;import bank.service.UserFacade;import bank.service.UserFacadeImpl;import com.opensymphony.xwork2.ActionSupport;public class RegistAction extends ActionSupport{ //private String userNo;//用户账号，系统自动生成 private String username;//用户名 private String password;//密码 private String confirmPassword;//确认密码 private int userAge;//用户年龄 private String userSex;//性别 private String tel;//用户电话号码 private String address;//用户住址 private String city; //private UserInfo userInfo=new UserInfo(); public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getConfirmPassword() { return confirmPassword; } public void setConfirmPassword(String confirmPassword) { this.confirmPassword = confirmPassword; } public int getUserAge() { return userAge; } public void setUserAge(int userAge) { this.userAge = userAge; } public String getUserSex() { return userSex; } public void setUserSex(String userSex) { this.userSex = userSex; } public String getTel() { return tel; } public void setTel(String tel) { this.tel = tel; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public String getCity() { return city; } public void setCity(String city) { this.city = city; } public String regist(){ //注册新用户操作 UserFacade userFacade=new UserFacadeImpl(); UserInfo userInfo=new UserInfo(); //从页面取得对应的值，并且赋给对象userInfo String address=getAddress()+getCity();//从doubleselect标签中获得注册用户的地址，包括父子列表中的 userInfo.setAddress(address); //this.userInfo.setConfirmPassword(getConfirmPassword()); userInfo.setPassword(getPassword());[color=#FF0000]//调试时，可以看到这里也是null[/color] userInfo.setTel(getTel()); userInfo.setUserAge(getUserAge()); userInfo.setUserSex(getUserSex()); userInfo.setUsername(getUsername()); System.out.println(getUsername()+"打盹儿"+password+username+tel);//[color=#FF0000]这里在控制台打出来的都是null[/color] try{ userFacade.registService(userInfo);return "registSuccess";了？ return "registSuccess"; }catch(Exception e){ e.printStackTrace(); return "error"; } } }
<action name="regist" class="bank.action.RegistAction" method="regist"> <result name="registSuccess">/registSuccess.jsp</result> <result name="error">/registError.jsp</result> <interceptor-ref name="tokenSession"></interceptor-ref> <interceptor-ref name="defaultStack"></interceptor-ref></action>
