To add struts to your project:
1: Click on Project Right click to select MyEclipse
2: Select Add Struts capadilities
3: Select 2.1
1. Build a package in SRC, create a new class in the package and inherit the Actionsupport interface, and rewrite the Execute () method inside.
The code is:
Package classwork;
Import Com.opensymphony.xwork2.ActionSupport;
@SuppressWarnings ("Serial")
public class Loginaction extends Actionsupport {
Private String UserID;
Private String passwork;
Public String GetUserID () {
return UserID;
}
public void Setuserid (String userID) {
This.userid = UserID;
}
Public String getpasswork () {
return passwork;
}
public void Setpasswork (String passwork) {
This.passwork = passwork;
}
@Override
Public String Execute () throws Exception {
TODO auto-generated Method Stub
if (Userid.equals ("AAA") &&passwork.equals ("123"))
Return "Success";
else return "error";
}
}
2. Create a new action in Struts.xml (note: The string "Success", "Error" returned in Execute () in class is the same as the value of name in the action)
<package name= "Default" extends= "Struts-default" >
<!--User Login-
<action name= "Userlogin" class= "Classwork.loginaction" >
<result name= "Success" >/main.jsp</result>
<result name= "Error" >/error.jsp</result>
</action>
</package>
3.1 Editing the login interface in the JSP
<body>
<form action= "Userlogin.action" method= "POST" >
User name: <input type= "text" name= "UserID" ><br>
Password: <input type= "text" name= "Passwork" ><br>
<input type= "Submit" value= "Login" >
</form>
</body>
3.2 Edit Login success and Failure page in JSP (note: The Save format changes to UTF-8, the login success and failure page name is the same as "main.jsp" and "error.jsp" in the action.)
