方式一：将VO的东西封装到Action里面
编写Action方法
package action;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport{
private String username;
private String password;
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;
}
@Override
public String execute() throws Exception {
if ("aaa".equalsIgnoreCase(username)&&"aaa".equalsIgnoreCase(password)) {
return "loginSuc";
}else {
return "loginFail";
}
}
}
配置文件
<action name="mylogin" class="action.LoginAction">
<result name="input">/mylogin．ｊｓp</result>
<result name="loginSuc">/ok．ｊｓp</result>
<result name="loginFail">/errok．ｊｓp</result>
</action>
然后编写登录的JSP页面
<s:form action="mylogin.action">
<table width="30%" align="center">
<tr>
<td>
<s:textfield key="username" label="USERNAME" />
</td>
</tr>
<tr>
<td>
<s:password key="password" label="PASSWORD" />
</td>
</tr>
<tr>
<td>
<s:submit value="SUBMIT" />
</td>
</tr>
</table>
</s:form>
注意这里面的JSP里面的表单名称要与Action里面的名称保持一致的1
也可以将其抽出来/
方式二：定义一个VO对象
自定义vo文件名：LoginVO.java
文件内容：
package struts2.login;
public class LoginVO {
private String username;
private String password;
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;
}
}
在Action文件中，要使用这个vo
文件内容：
package struts2.login;
public class LoginAction {
private LoginVO user = null;
public String execute() {
System.out.println (LoginAction.class.hashCode());
if (user.getUsername().equalsIgnoreCase("aaa") &&
user.getPassword().equals("aaaaaa")) {
return "loginSuc";
}
else {
return "loginFail";
}
}
public LoginVO getUser() {
return user;
}
public void setUser(LoginVO user) {
this.user = user;
}
}
登陆成功的文件如下：
<%@ page contentType="text/html; charset=gb2312" %>
<%@ taglib url="/struts-tags" prefix="s"%>
<meta http-equiv="content-type" content="text/html;charset=gb2312">
欢迎您，<s:property name="user.username">登录成功。
注意login文件的部分也要进行修改
文件内容如下：
<meta http-equiv="content-type" content="text/html;charset=gb2312">
<title>login2</title>
<form action="login.action" method="post">
username:<input type="input" name="user.username"><br>
password:<input type="input" name="user.password"><br>
<input type="submit" value="登录">
</form>
