JTable列标题的本地化

Question

我有一个javax.swing.table.AbstractTableModel子类，它定义表列标题，如下所示： protected String[] columnNames = new String[] { "Column1", "Column2};如何从资源包中本地化columnNames我想从.properties文件中读取列标题，而不是在代码中对其进行硬编码，是否有更好的方法呢？

Answer 1

You override the getColumnName() in order to return the localized value of the column name.

For example :

private ResourceBundle res = ResourceBundle.getBundle("MyResource");

@Override
public String getColumnName( int column ) {
    return res.getString(columnNames[column]);
}

Answer 2

Easiest way is to modify your assignment of columnNames:

protected String[] columnNames = getColumnNames();
//...
private static String[] getColumnNames() {
  return ResourceBundle.getBundle("AppResources").getString("headings").split(",");
}

Where AppResources (or AppResources_en, AppResources_fr_FR etc.) is a class that extends ResourceBundle and contains a key called "headings" which returns a comma separated list of headings.
