当我尝试运行代码时出现此错误。错误：
Exception in thread "main" com.sun.xml.internal.ws.spi.db.DatabindingException: com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
java.util.List is an interface, and JAXB can't handle interfaces.
this problem is related to the following location:

任何人都可以帮我解决这些错误。
答案 0 :(得分：0)
在接口和实现类中将List更改为ArrayList，然后可以解决您的异常
