Hybris 自定义电子邮件设置自定义属性

Question

我正在创建一个自定义电子邮件，应在填写预约表格后发送给客户。我需要额外的属性，所以我扩展了AbstractEmailContext：public class AppointmentEmailContext extends AbstractEmailContext{   private String myAttribute;   ...}在我开始这个过程之前，我正在我的 EventListener 中设置属性：final AppointmentProcessModel storeFrontCustomerProcessModel = (AppointmentProcessModel) getBusinessProcessService()                .createProcess(                        "appointmentEmailProcess-" + event.getEmail() + "-" + System.currentTimeMillis(),                        "appointmentEmailProcess");storeFrontCustomerProcessModel.setMyAttribute("[e-mail]");getModelService().save(storeFrontCustomerProcessModel);getBusinessProcessService().startProcess(storeFrontCustomerProcessModel);在我无法获取这些参数的init方法中，AppointmentEmailContext我可以正确设置它们并将它们传递给电子邮件模板。另一件事是，在init方法中输入的 ProcessModel不是 的实例AppointmentProcessModel，而是 的实例StoreFrontCustomerProcessModel，即使我AppointmentProcessModel正在扩展它。我也尝试添加AppointmentProcessModel这样的：public class AppointmentEmailContext extends AbstractEmailContext<AppointmentProcessModel>{...}并使用正确的参数调整 init 方法（+ 添加覆盖方法），但随后在创建过程时出现错误：ERROR [hybrisHTTP21] [HybrisApplicationEventMulticaster] java.lang.InstantiationException: mypackage.core.appointment.model.AppointmentProcessModel java.lang.RuntimeException: java.lang.InstantiationException: mypackage.core.appointment.model.AppointmentProcessModel我不知道保留这些属性是否有问题，或者我是否应该以其他方式传递这些属性。更新：我试图添加AppointmentProcess到*-items.xml文件，我做系统更新，但没有改变。我在后台检查了该类型已添加并且它是从StoreFrontCustomerProcess. 定义如下：        <itemtype code="AppointmentProcess" extends="StoreFrontCustomerProcess"                  autocreate="true" generate="true"                  jaloclass="mypackage.jalo.AppointmentProcess">            <attributes>                <attribute qualifier="email" type="java.lang.String">                    <persistence type="property" />                </attribute>            </attributes>        </itemtype>

Answer 1

通过 HMC 交叉验证，您的属性是否保存在 storeFrontCustomerProcessModel 中？

尝试更改AppointmentEmailContext类，如

public class AppointmentEmailContext extends AbstractEmailContext<AppointmentProcessModel>

{

   private String myAttribute;

    @Override

    public void init(final AppointmentProcessModel appointmentProcessModel, final EmailPageModel emailPageModel)

    {

        super.init(appointmentProcessModel, emailPageModel);

        myAttribute = appointmentProcessModel.getMyAttribute();

    }

    public String getMyAttribute() {

        return myAttribute;

    }

    //...

}

用户尚未创建 Item 类型AppointmentProcess，后来他创建了它，正如我在评论中提到的，问题已解决！！
