我正在創建一個struts2應用程序。我希望用戶登錄到他們的 帳戶。如果找到記錄，則應該轉到success.jsp。如果 該帳戶未找到，它應該默認爲error.jsp。他們可以 然後註冊。我遇到的問題是，無論數據庫中的記錄是否爲 ，我都會重定向到我的error.jsp。 我將在這裏得到一些幫助，一些喜歡解釋去用它struts2應用程序默認爲error.jsp
這裏是我的文件：
StudentInfo

//import
public class StudentInfo implements Serializable{
private int studentId;
private String userName;

public void setStudentId(int studentId) {
this.studentId = studentId;
}
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;
}
public String getPassword1() {

}
public void setPassword1(String password1) {
this.password1 = password1;
}
public String getFirstName() {

public void setFirstName(String firstName) {
this.firstName = firstName;
