在这一章节中，我们创建一个web工程为：struts2passwd，演示<s:password>的使用。完整的工程目录结构如下：
在struts2中，可以使用<s:password>来创建html密码字段。例如，可以声明“s:password”键属性或者标签和名称属性。
<s:password key="password" /> //or <s:textfield label="password" name="password" />
<td class="tdlabel"> <label for="registeruser_password" class="label">password:</label> </td> <td> <input type="password" name="password" id="registeruser_password"/> </td>
global.properties
#global messages username = 用名名 password = 密码 confirmpassword = 确认密码 submit = 提交
registeraction.properties
#error message username.required = username is required password.required = password is required cpassword.required = confirm password is required cpassword.notmatch = confirm password is not match
registeraction.java
package com.h3.user.action;
import com.opensymphony.xwork2.actionsupport;
public class registeraction extends actionsupport{
private string username;
private string password;
private string confirmpassword;
public string getpassword() {
return password;
}
public void setpassword(string password) {
this.password = password;
}
public string getconfirmpassword() {

}
public void setconfirmpassword(string confirmpassword) {
this.confirmpassword = confirmpassword;
}
public string getusername() {
return username;
}
public void setusername(string username) {
this.username = username;
}
//business logic
public string execute() {
return "success";
}
//simple validation
public void validate(){
if("".equals(getusername())){
addfielderror("username", gettext("username.required"));
}
if("".equals(getpassword())){
addfielderror("password", gettext("password.required"));
}
