我想将我从ajax请求获得的XMLDocument对象转换为字符串.我试过用

new XMLSerializer()).serializeToString(xmlObject)

我收到以下回复: -

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><ns2:errorList xmlns:ns2="http://www.example.com/api/delivery/V1"><error code="DOMAIN_VALIDATE" path="delivery.shipper"><message>empty</message></error><error code="DOMAIN_VALIDATE" path="delivery.shipperSite"><message>empty</message></error><error code="DOMAIN_VALIDATE" path="delivery.leg"><message>invalid</message></error></ns2:errorList>

表示该方法将整个XMLDocument转换为字符串,包括第一个标记

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

我不想要这部分回复.有没有办法做到这一点.注意:我不想使用"substr"等变通方法.

我在我的应用程序中使用tomcat 7.当我启动服务器时,它会在启动时显示以下警告消息: -

我想使用sling taglib在我的jsp中实例化一个服务对象.在正常情况下,服务类只由一个类实现,它非常简单: -

RegistrationService registrationService = sling.getService(RegistrationService.class);

但是如果服务类有多个实现类,那么我们如何确保为特定类实例化对象.

我的java类是这样的: -
1.接口:RegistrationService
2.实现类1: -

@Properties({@Property(name = "datasource", value = "SBWS"})
   @Service
   public class RegistrationServiceImpl implements RegistrationService{
   }

3.实施类2: -

@Properties({@Property(name = "datasource", value = "SOLR"})
   @Service
   public class RegistrationServiceImpl implements RegistrationService{
   }

我怎样才能确保使用

RegistrationService registrationService = sling.getService(RegistrationService.class);

在jsp中将实例化服务,让我们说实现类1
