我有这段代码
@FXML
void search_all(ActionEvent event) throws SQLException {
Connection conn = null;
PreparedStatement stmt = null;
Properties connectionProps = new Properties();
connectionProps.put("user", "root");
connectionProps.put("password", "916626");
String connectionString = "jdbc:mysql://localhost:3306/DBS_projekt";
list_search = FXCollections.observableArrayList();
try {
conn = DriverManager.getConnection(connectionString, connectionProps);
stmt = conn.prepareStatement("SELECT * FROM bycikel");
ResultSet rs = stmt.executeQuery();
// ---- ADD COLUMNS ---
for(int i=0 ; i<rs.getMetaData().getColumnCount(); i++){
final int j = i;
TableColumn mycolumn = new TableColumn(rs.getMetaData().getColumnName(i+1));
mycolumn.setCellValueFactory(new Callback<CellDataFeatures<ObservableList, String>, ObservableValue<String>>()
{
public ObservableValue<String> call (CellDataFeatures < ObservableList, String > param){
return new SimpleStringProperty(param.getValue().get(j).toString());
}
});
tableview1.getColumns().addAll(mycolumn);
}
while(rs.next()){
ObservableList<String> riadok = FXCollections.observableArrayList();
for(int i=1 ; i<rs.getMetaData().getColumnCount(); i++){
riadok.add(rs.getString(i));
}
list_search.add(riadok);
}
tableview1.setItems(list_search);
}catch (SQLException e) {
e.printStackTrace();
} finally {
stmt.close();
}
}
错误是：

你可以帮我解决这个错误吗？ 我无法理解这一部分：
at sample.Controller$1.call(Controller.java:383) ...........is at line .....
public ObservableValue<String> call (CellDataFeatures < ObservableList, String > param){......
