推荐答案
您正在使用旧版本的JAXB.版本2.2.11具有null检查: PropertyInfoImpl.java#371
You're using an old version of JAXB.Version 2.2.11 has a null check: PropertyInfoImpl.java#371
case QUALIFIED:
QName typeName = parent.getTypeName();
if(typeName!=null) {
uri = typeName.getNamespaceURI();
} else {
uri = xs.namespace();
}
if(uri.length()==0) {
uri = parent.builder.defaultNsUri;
}
break;
2.0版没有null检查: PropertyInfoImpl.java#286
Version 2.0 doesn't have a null check: PropertyInfoImpl.java#286
case QUALIFIED:
uri = parent.getTypeName().getNamespaceURI();
if(uri.length()==0) {
uri = parent.builder.defaultNsUri;
}
break;
