如何打印 roo uiModel 中的值？

Question

当我在 jspx 页面中打印 uiModel ${subscribers} 时。我收到以下信息：

"[Code: S0001, FirstName: John, 
               LastName: Smith, 
               Message: New subscriber, 
               Active: 1, 
               RouteID: Code: 1, 
               Name: Route 1, 
               Active: 1, 
               TruckID: 
  Code: t1000, 
               Name: Truck 1, 
               Active: 1, 
               DistrictID: 
  Code: dst1, 
               Name: Colombo 1, 
               Active: 1, 
               LastModifiedDate: 2011-04-02 15:40:25.0, 
               LastModifiedUser: admin, 
               LastModifiedDate: 2011-04-02 00:00:00.0, 
               LastModifiedUser: admin, 
               LastModifiedDate: 2011-04-02 00:00:00.0, 
               LastModifiedUser: admin, 
               PaymentTypeID: 

  Code: 1, 
               Name: Cash, 
               LastModifiedDate: 2011-04-02 00:00:00.0, 
               LastModifiedUser: admin, 
               LastModifiedDate: 2011-04-02 00:00:00.0, 
               LastModifiedUser: admin]"

如何仅打印属性“代码”：

我尝试了以下操作，但它打印空字符串：

${subscribers[Code]}

我还有一个问题。如何发送多个 uiModel 并以表单显示并更新它们？

Answer 1

通常，您推入 Roo 在文件“[Entityname]_Roo:ToString.aj”中生成的 toString 方法并重新实现它，以便它返回您想要的值。
像这样的东西：

public String [Entityname].toString() {
        StringBuilder sb = new StringBuilder();
        sb.append("Code: ").append(getCode());
        return sb.toString();
    }
