ユーザー名とパスワードが検証されると、id、firstName、lastName がアクセスのためにクラス内に設定されるように、DB にアクセスする単純なログイン ページを作成しようとしています。私はこのエラーが発生します:
javax.servlet.ServletException: Unable to create managed bean UserBean. The following problems were found:
- Property firstName for managed bean UserBean does not exist. Check that appropriate getter and/or setter methods exist.
- Property id for managed bean UserBean does not exist. Check that appropriate getter and/or setter methods exist.
- Property lastName for managed bean UserBean does not exist. Check that appropriate getter and/or setter methods exist.
javax.faces.webapp.FacesServlet.service(FacesServlet.java:321)
id、firstName、lastName のゲッターはありますが、検証後に設定されるため、セッターはありません。
ここにクラス UserBean があります
public class UserBean {
private static String password, username, id, firstName, lastName;
public enum DBfields { BLANK, USERNAME, ID, PASSWORD, FIRSTNAME, LASTNAME };
public String getPassword() {
return password;
}
public void setPassword( String value ) {
password = value;
}
public String getUsername() {
return username;
}
public void setUsername( String value ) {
username = value;
}
public static String getId() {
return id;
}
public static String getFirstname() {
return firstName;
}
public static String getLastname() {
return lastName;
}
public String loginUser() throws Exception {
if( loginValidate( username, password ) )
return "success";
else
return "fail";
}
public static boolean loginValidate( String username, String Password ) throws Exception{
String DBuser;
String DBpass = "asdf";
PreparedStatement table = connectToTable( "firstsql", "users");
ResultSet row = table.executeQuery();;
while(row.next()){
DBuser = row.getString(DBfields.USERNAME.name());
if(username.equals(DBuser)){
DBpass = row.getString(DBfields.PASSWORD.name());
break;
}
}
if(password.equals(DBpass)){
id = row.getString(DBfields.ID.name());
firstName = row.getString(DBfields.FIRSTNAME.name());
lastName = row.getString(DBfields.LASTNAME.name());
return true;
} else
return false;
}
そして私のfaces-config
