JavaFX TableView：线程“ JavaFX应用程序线程”中的异常java.lang.IndexOutOfBoundsException

• 问答

我试图用来自通过JDBC运行的MySQL查询的一些数据填充JavaFx TableView。我以前在填充表时没有问题，直到更改查询以选择表中除其中之一以外的所有列为止。该查询可以在MySQL Workbench中完美运行。

这是我的代码中负责填充TableView的部分：

ObservableList<ObservableList<String>> data = FXCollections.observableArrayList();
TableView table = new TableView();
// rs is the ResultSet returned by executing the SELECT query that should be filling the table
ResultSetMetaData rsmd = rs.getMetaData();
for(int i = 1; i <= rsmd.getcolumnCount(); i++){
    final int j = i; 
    TableColumn col = new TableColumn(rsmd.getcolumnLabel(i));
    col.setCellValueFactory(new Callback<CellDataFeatures<ObservableList,String>,ObservableValue<String>>(){
        public ObservableValue<String> call(CellDataFeatures<ObservableList,String> param) {
            // The line below is Main.java:194,the problem source according to the stack trace
            return new SimpleStringProperty(param.getvalue().get(j).toString());
        }
    }); 
    table.getcolumns().addAll(col); 
}

while(rs.next()){
    ObservableList<String> row = FXCollections.observableArrayList();
for(int i = 1 ; i <= rsmd.getcolumnCount(); i++){
    row.add(rs.getString(i));
}
data.add(row);
}
table.setItems(data);`

堆栈跟踪表明问题出在代码段指示的行中。这是堆栈跟踪：

请尝试

  • 将SimpleStringProperty（param.getValue（）。get（ j ）。toString（））更改为 SimpleStringProperty（param.getValue（）。get（ j-1 ）。toString（）） 或
    • 最终int j = i;最终int j = i-1;
