action：
import cn.betel.softwareinstallhelper.model.Admin;
import cn.betel.softwareinstallhelper.service.AdminLoginService;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class AdminLoginAction extends ActionSupport{
/**
*
*/
private static final long serialVersionUID = 1L;
public AdminLoginService als= new AdminLoginService();
public String adminname;
public String adminpassword;
public Admin admin;
public String getAdminpassword() {
return adminpassword;
}
public void setAdminpassword(String adminpassword) {
this.adminpassword = adminpassword;
}
public String getAdminname() {
return adminname;
}
public void setAdminname(String adminname) {
this.adminname = adminname;
}
public Admin getAdmin() {
return admin;
}
public void setAdmin(Admin admin) {
this.admin = admin;
}
public String login(){
System.out.println(adminname);
//登录
admin=new Admin();
admin.setAdminname(adminname);
admin.setAdminpassword(adminpassword);
ActionContext ctx = ActionContext.getContext();
ctx.getSession().put("admin", admin);
return als.dologin(adminname, adminpassword);
}
}
service：
public class AdminLoginService {
//登录
public String dologin(String adminname,String adminpassword){
String issuccess="error";
if (adminname==null||adminpassword==null) {
issuccess="error";
}else {
String sql="select * from admin where adminname=?";
System.out.println(sql);
Map<String, String> map=DBControl.queryOne(sql, adminname);
System.out.println(map);
if (map!=null) {
if (map.get("adminpassword").equals(adminpassword)) {
System.out.println(map.get("adminpassword").equals(adminpassword));
//JOptionPane.showMessageDialog(null,"登录成功" );
issuccess="success";
}
}else {
issuccess="error";
}
}
return issuccess;
}
}
