내 Driver 클래스에 이미 속성 전자 메일이 있지만이 오류가 계속 발생합니다. 이것은 내 드라이버 클래스http 상태가 500입니다. 'pack1.Driver'유형의 bean에서 'email'속성에 대한 정보를 찾을 수 없습니다.
package pack1;
import java.sql.*;
public class Driver {
private String name, email, password, contact;
private char gender;
public Driver()
{
name = "";
email = "";
password = "";
contact = "";
}
public void setDriverName(String name){
this.name = name;
}
public void setDriverGender(char gender){
this.gender=gender;
}
public void setDriverEmail(String email){
this.email = email;
}
public void setDriverPassword(String password){
this.password = password;
}
public void setDriverContact(String contact){
this.contact = contact;
}
public String getDriverName(){
return name;
}
public char getDriverGender(){
return gender;
}
public String getDriverEmail(){
return email;
}
public String getDriverPassword(){
return password;
}
public String getDriverContact(){
return contact;
}
public static boolean LoginDriver(String email, String password){
boolean validate = false;
try{
Connection con = DatabaseConnectionFactory.createConnection();
Statement st = con.createStatement();
PreparedStatement ps1 = con.prepareStatement("select * from driver where Email=? and Password=? ");
ps1.setString(3, email);
ps1.setString(4, password);
ResultSet rs1 = ps1.executeQuery();
validate = rs1.next();
con.close();
}
catch(Exception e){
e.printStackTrace();
}
return validate;
}
}

나는 소문자로 속성 이름을 넣는 해결책을 이미 시도했는데 왜 분명히 거기부터 속성 전자 메일을 찾을 수 없는지 이해할 수 없다. 내가 볼 수없는 뭔가가 있어야합니다. 너의 도움이 정말로 필요해. 사전에 감사합니다
귀하의 속성의 결과로 "driverEmail"라는
자바 당 콩 규칙, 당신의 getter 및 setter는해야 재산과 같은 이름. (즉, setEmail vice setDriverEmail). 이 문제를 해결하는 방법이 있지만 실제로이 문제를 해결할 방법이 없기 때문에 협약을 따라야합니다. – rmlan
@rmlan 오, 세상에 내가 실제로해야만하는 모든 것. 네가 내 목숨을 구해 주셔서 정말 고마워! –
