我有POJO：
class PersonJob {
private PersonAddress address;
//a buch of fields (non Object type)
}
class PersonAddress extends AbstractContact {
//empty fields class
}
class AbstractContact {
private Object contactId;
public Object getContactId() { return this.contactId }
public void setContactId(Object contactId) {this.contactId = contactId}
}
AbstractContact类放置在外部库中。
我正在将PodamFactory与我的DataProvider一起使用，它扩展了AsbractRandomDataProviderStrategy以填充PersonJob。但是当JAXB序列化它时，我会发出这样的错误：

是否有一种方法可以通过扩展AsbractRandomDataProviderStrategy的DataProvider来关闭AbstractContact类的contactId字段的实例化？
最佳答案
首先，可以将contactId更改为实际类型吗？我敢打赌，它不是Object，但正如声明的那样，它会使Podam感到困惑。
如果前者不是一个选择，那么您可以做三件事：
用contactId注释排除@PodamExclude字段
使用类信息策略排除contactId字段
DefaultClassInfoStrategy classInfoStrategy = DefaultClassInfoStrategy.getInstance（）;
classInfoStrategy.addExcludedField（PersonAddress.class，“ contactId”）;
podamFactory.setClassStrategy（classInfoStrategy）;
生产后甚至更好的pojo.setContactId(null);只需致电pojo.setContactId(yourActualAddressObject);
关于java - 在podam中关闭java.langObject初始化，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/39034570/
