以下内容应有所帮助：
JAXB2ValidationEventCollector
ValidationEventCollector来自JAXB
1（JSR-31），并且似乎不太支持我们在JAXB
2（JSR-222）中对验证所做的更改。您可以通过创建
ValidationEventHandler类似于以下内容的子类来解决此问题。
package forum12295028;import javax.xml.bind.ValidationEvent;import javax.xml.bind.util.ValidationEventCollector;class JAXB2ValidationEventCollector extends ValidationEventCollector { @Override public boolean handleEvent(ValidationEvent event) { super.handleEvent(event); return true; }}例
以下示例可用于证明一切正常
顾客
package forum12295028;import java.util.*;import javax.xml.bind.annotation.*;@XmlRootElementpublic class Customer { private String name; private List<PhoneNumber> phoneNumbers = new ArrayList<PhoneNumber>(); public String getName() { return name; } public void setName(String name) { this.name = name; } @XmlElement(name="phone-number") public List<PhoneNumber> getPhoneNumbers() { return phoneNumbers; } public void setPhoneNumbers(List<PhoneNumber> phoneNumbers) { this.phoneNumbers = phoneNumbers; }}电话号码
