Action.java接口Action
packagecom.bjsxt.servlet.action;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
publicinterfaceAction{
publicStringservice（HttpServletRequestrequest,HttpServletResponseresponse）;
}
AddUserAction.java实现Action接口的添加类
packagecom.bjsxt.servlet.action;
importjava.util.List;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importcom.bjsxt.servlet.UserManager;
publicclassAddUserActionimplementsAction{
@Override
publicStringservice（HttpServletRequestrequest,
HttpServletResponseresponse）{
//取得表单数据
Stringusername=request.getParameter（"username"）;
UserManageruserManager=newUserManager（）;
ListuserList=userManager.addUser（username）;
request.setAttribute（"userlist",userList）;
return"/seccess.jsp";
}
}
ModifyUserAction.java实现Action接口的修改类
packagecom.bjsxt.servlet.action;
importjava.util.List;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importcom.bjsxt.servlet.UserManager;
publicclassModifyUserActionimplementsAction{

UserManageruserManager=newUserManager（）;
ListuserList=userManager.findUserByName（username）;
request.setAttribute（"userlist",userList）;
return"/seccess.jsp";
}
}
UserManameger.java根据页面信息取得数据
packagecom.bjsxt.servlet;
importjava.util.ArrayList;
importjava.util.List;
publicclassUserManager{
//添加用户
publicListaddUser（Stringname）{
ListuserList=newArrayList（）;
userList.add（"添加数据一"）;
userList.add（"添加数据二"）;
returnuserList;
}
//查找用户
publicListfindUserByName（Stringname）{
ListuserList=newArrayList（）;
userList.add（"查找数据一"）;
userList.add（"查找数据二"）;
returnuserList;
