我有一个JavaFX TableView，我使用JPQL Query填充EclipseLink，从Client表中获取数据{ {1}} MySQL。填充表格所需的时间越长，database表中存储的数据就越多，这会给用户带来滞后感。因为加载Client需要4 seconds而变得非常烦人，我在获取记录之前创建了一个1600 records来加载GUI，但它没有任何区别。你们有什么想法来优化我的代码吗？这是：
这是启动线程然后获取的
Thread：
initialize()获取数据：
@Override
public void initialize(URL url, ResourceBundle rb) {
Thread refresh = new Thread(new Runnable() {
@Override
public void run() {
Platform.runLater(new Runnable() {
@Override
public void run() {
//Optilight.echo("showLoadingWindow()");
//FactureTemplateController.showLoadingWindow();
mouseRightClick();
refreshData();
//Optilight.echo("hideLoadingWindow()");
//FactureTemplateController.hideLoadingWindow();
return;
}
});
}
});
refresh.setDaemon(true);
refresh.start();
}
ClientFX.java：
public void refreshData(){
em = Optilight.emf.createEntityManager();
List<Client> lst = em.createQuery("SELECT c FROM Client c JOIN FETCH c.personne p ORDER BY c.codePersonne DESC").getResultList();
data = FXCollections.observableArrayList();
for (Client client : lst) {
data.add(new ClientFX(
client.getCodePersonne(), client.getPersonne().getNom(),

}
em.close();
