http 상태가 500입니다. 'pack1.Driver'유형의 bean에서 'email'속성에 대한 정보를 찾을 수 없습니다.

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! –

public void setDriverEmail(String email){ 
    this.email = email; 
} 

public String getDriverEmail(){ 
    return email; 
}

가로 변경합니다 :

public void setEmail(String email){ 
    this.email = email; 
} 

public String getEmail(){ 
    return email; 
}
