Web Service : 無法在 @WebService 中使用 @Autowired

Web Service : 無法在 @WebService 中使用 @Autowired

Solution:

可以使用 springframework  提供的 SpringBeanAutowiringSupport


 import org.springframework.web.context.support.SpringBeanAutowiringSupport;
@WebService()
public class Trade extends SpringBeanAutowiringSupport {// 在 WebService 中使用 Spring @Autowired

  @Resource
  WebServiceContext wsCtxt;

  @Autowired
  private IGameOrderService gameOrderService;

詳見 17.5.5 那一段

Web Service : llegalAnnotationsException: Two classes have the same XML type name

Web Service : com.sun.xml.bind.v2.runtime.IllegalAnnotationsException:
Two classes have the same XML type name

系統環境:

JBoss: JBoss_4.2.2.GA
JDK: JDK1.6.0_14
IDE: NetBeans 6.9

code :

@WebService()
public class Trade {

@WebMethod(operationName = "gameOrder")
public GameOrderResponse gameOrder(
@WebParam(name = "GameOrderId") String gameOrderId,
@WebParam(name = "GameCode") String gameCode) {
GameOrderResponse response = null;
....
return response;
}
}

Error:

java.lang.IllegalStateException: Cannot build JAXB context
......
......
Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
Two classes have the same XML type name "{http://ws.billing.lkt.com/}gameOrderResponse". Use @XmlType.name and @XmlType.namespace to assign different names to them.
this problem is related to the following location:
at com.lkt.billing.ws.type.GameOrderResponse
at private com.lkt.billing.ws.type.GameOrderResponse com.lkt.billing.ws.jaxws.GameOrderResponse._return
at com.lkt.billing.ws.jaxws.GameOrderResponse
this problem is related to the following location:
at com.lkt.billing.ws.jaxws.GameOrderResponse

Solution:

JAX-WS 會為 annotation @WebMethod 的每個方法, 自動生成一個 message element, 名為 methodName + "Response" ; 恰巧 return object 的 class 也命名相同, 因此會有衝突.
方法一 : 不要使用到 methodName + "Response" 來命名 response classes.
方法二 : 使用 @XMLType 指定不同的 namespaces 給 message elements.
