我有一个表单，用户应该输入一些值以从 Web 服务获取一些信息。首先，用户填写表单，然后当他单击请求按钮时调用 web 服务。直到这里一切正常。但是随着网络服务返回信息，我必须用新数据重新渲染数据表。这是我的页面：
<h:body>
<h:form id="formCus">
<h:outputLabel value="Müşteri Tipi: *"/>
<p:selectOneMenu id="customerType" value="#{customerService.musteriTipi}" style="width: 39%">
<f:selectItem itemLabel="" itemValue=" " />
<f:selectItem itemLabel="Bireysel" itemValue="BIREYSEL" />
<f:selectItem itemLabel="Tüzel" itemValue="TUZEL" />
<f:selectItem itemLabel="Yabancı" itemValue="YABANCI" />
<p:ajax event="change" update="#{customerService.musteriTipi}"/>

这是我的背豆：
//some getter and setters
List<Customers> customer = new ArrayList<Customers>();
public List<Customers> getCustomer() {
return customer;
}
public void setCustomer(List<Customers> customer) {
this.customer = customer;
}
public String request() {
final RequestContext context = RequestContext.getCurrentInstance();
//System.out.println("Progress...");
//musteriSorgula(musteriSorgulaKriter());
new Thread(new Runnable() {
public void run() {
try {
musteriKodu = String.valueOf(musteriSorgula(musteriSorgulaKriter()).getMusteriBilgisi().getMusteriKodu());
List<TelefonBilgisi> tel_result = telefonSorgula(telefonSorgulaKriter(musteriKodu)).getMusteriTelefonListesi();
//telefon = tel_result.getMusteriTelefonListesi().get(0).getTelefonNo();
if (tel_result.size() > 0) {
for (TelefonBilgisi t : tel_result) {
telefon = t.getTelefonNo();
}
} else {
telefon = "No telephone.";
}
List<UavtAdresBilgisi> uavt_result = uavtAdresSorgula(uavtAdresSorgulaKriter(musteriKodu)).getMusteriUavtAdresListesi();
if (uavt_result.size() > 0) {
for (UavtAdresBilgisi u : uavt_result) {
adres = String.valueOf(u.getSehir()) + ", " + String.valueOf(u.getBucak()) + ", " + String.valueOf(u.getKasaba());
}
} else {
adres = "No address.";
}
Customers cust = new Customers(musteriTipi, BigInteger.valueOf(Long.valueOf(musteriKodu)), adFirmaAdi, soyadUnvan, telefon, adres, mail, projectId);
if (!customer.contains(cust)) {
customer.add(cust);
System.out.println("Customer has been added.");
} else {
System.out.println("Customer is still in the list.");
}
} catch (Exception ex) {
Logger.getLogger(CustomerService.class.getName()).log(Level.SEVERE, null, ex);
context.execute("alert('Try again.')");
}
}
}).start();
context.execute("panelwv.close()");
return "";
}
back bean 可以连接到 web 服务并收集信息，我可以在日志中看到。一开始我的数据表是空的。我想要的是将新数据显示为 Web 服务响应。context.update("personList")当我把它放在下面时不起作用：
customer.add(cust);
如果有人可以帮助我，我将不胜感激。
