Struts 1登錄應用程序示例錯誤

我是Struts新手，試圖執行登錄表單。但是它沒有在ACTION類中的默認構造函數之後執行。Struts 1登錄應用程序示例錯誤

LoginForm.java

package struts.login.action; 

import org.apache.struts.action.ActionForm; 

@SuppressWarnings("serial") 
public class LoginForm extends ActionForm { 

public LoginForm() { 

} 

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; 
} 


}

LoginAction.java

package struts.login.action; 

import javax.servlet.ServletRequest; 
import javax.servlet.ServletResponse; 

import org.apache.struts.action.Action; 
import org.apache.struts.action.ActionForm; 
import org.apache.struts.action.ActionForward; 
import org.apache.struts.action.ActionMapping; 

public class LoginAction extends Action { 

private final static String SUCCESS = "success"; 
private final static String FAILURE = "failure"; 
//private final static String FAILURE = "failure"; 

public LoginAction() { 
    System.out.println("default constructor of Login Action"); 
} 

@Override 
public ActionForward execute(ActionMapping mapping, ActionForm form, 
     ServletRequest request, ServletResponse response) throws Exception  { 

    LoginForm loginForm = (LoginForm) form; 
    if(loginForm.getUsername().equals(loginForm.getPassword())){ 
     return mapping.findForward(SUCCESS);  
    } 
    else{ 
     return mapping.findForward(FAILURE);  
    } 

} 
}

的Login.jsp

<%@ taglib uri="/WEB-INF/tld/struts-html.tld" prefix="html"%> 
<html> 
<head> 
<title>Login Page</title> 
</head> 
<body> 
<div style="color:red"> 

</div> 
<html:form action="/Login" method="get"> 
    User Name :<html:text property="username"/><br> 
    Password :<html:password property="password"/> 
    <html:submit value="Login Here" /> 
</html:form> 
</body> 
</html>

的success.jsp

個

<html> 
<head> 
<title>Insert title here</title> 
</head> 
<body> 
Successfully logged in! 
</body> 
</html>

failure.jsp

<html> 
<head> 
<title>Insert title here</title> 
</head> 
<body> 
login failed please try again! 
</body> 
</html>

struts-config.xml中

<?xml version="1.0" encoding="UTF-8"?> 

<!DOCTYPE struts-config PUBLIC

</jsp-config> 
</web-app>

我已經包含在struts-html.tld文件中的WEB-INF/tld文件夾。用戶名和密碼登錄後它不重定向到任何的success.jsp或failure.jsp頁

歡迎來到Stackoverflow，你得到了什麼類型的異常？ –

如果你是struts的新手，並且爲了自己的知識閱讀它，那麼比我的建議是從Struts2開始，而不是struts，因爲它已經宣佈它已經結束了。 –

我沒有在我的控制檯中發現任何異常。所以我認爲它可能與罐子有關。 – Roikka

那是因爲你已經通過的ServletRequest和ServletResponse的行動類而不是HttpServletRequest和HttpServlet的響應在執行方法.. 使用像繼

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

並導入這些東西：

import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse;

希望它會運行
