Struts1中实现登录实例_Struts1

添加支持(即jar包)后的步骤为：

(1)创建ActionForm

LoginForm.java

package com.mstf.struts.form;

import org.apache.struts.action.ActionForm;

public class LoginForm extends ActionForm {

String username;

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;
}

}

(2)创建控制器

LoginAction.java

package com.mstf.struts;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

import com.mstf.struts.form.LoginForm;

public class LoginAction extends Action {

public ActionForward execute(ActionMapping mapping,ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {

  //将ActionForm强制类型转换为LoginForm，并获取传过来的表单
LoginForm lgForm=(LoginForm)form;
  //获取表单元素的值
String username=lgForm.getUsername();
String password=lgForm.getPassword();
  //模拟调用javabean进行业务处理
if("scce".equals(username) && "123456".equals(password)){
return mapping.findForward("suc");
}else{
return mapping.findForward("fail");
}

}

(3)创建视图

<body>

</form>

</body>

success.jsp

<body>

<h1>用户名:${lf.username }</h1>

<h1>密码:${lf.password }</h1>

</body>

fail.jsp

<body>
