使用带注释的端点时,spring ws 找不到适配器
我正在使用 Java 6 和 spring-ws 创建一个非常简单的 Web 服务,它接收 BusquedaRequest Jaxb 对象形式的 2 个参数并返回相同的对象。
该对象是使用 xjc 编译器创建的,我使用 Jaxb2Marshaller 作为 mashaller 和 GenericMarshallingMethodEndpointAdapter 来转换为传入的 xml 并输出。我在扩展 AbstractMarshallingPayloadEndpoint 类时进行了此操作,但当我切换到使用 Endpoint 和有效负载注释时,它总是失败。
Web 服务启动正常,但当与客户端连接时,我收到此异常。
java.lang.IllegalStateException: No adapter for endpoint [public package.busqueda.ws.BusquedaRequest package.busqueda.ws.BusquedaEndpoint.getResultas(package.busqueda.ws.BusquedaRequest)]: Does your endpoint implement a supported interface like MessageHandler or PayloadEndpoint?

我已经看到对此问题的答复,建议使用我已经完成的 xjc 编译器来编译对象。还有人建议说适配器尚未在 spring-ws-servlet.xml 中定义,我也这样做了。请参阅下面定义的 spring-ws-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="busquedaEndpoint" class="package.BusquedaEndpoint" />
<bean class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter">
<constructor-arg ref="marshaller"/>
</bean>
<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="classesToBeBound">
<list>
<value>package.BusquedaRequest</value>
</list>
</property>
</bean>
<bean id="busqueda"
class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
<property name="schema" ref="schema" />
<property name="portTypeName" value="Busqueda" />
<property name="locationUri" value="/BusquedaService/" />
</bean>
<bean id="schema" class="org.springframework.xml.xsd.SimpleXsdSchema">
<property name="xsd" value="/WEB-INF/busqueda.xsd" />
</bean>
<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping"/>
</beans>
类端点如下:
package package.busqueda.ws;
import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;
@Endpoint
public class BusquedaEndpoint {
@PayloadRoot(localPart = "BusquedaRequest", namespace = "http://busqueda/schemas")
public BusquedaRequest getResultas( BusquedaRequest aRequest ) {
return aRequest;
}
}
我生成的 BusqeudaRequest 对象的 xsd 如下:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
attributeFormDefault="qualified"
xmlns="http://busqueda/schemas"
targetNamespace="http://busqueda/schemas">
<xs:element name="BusquedaRequest">
<xs:complexType>
<xs:all>
<xs:element name="Consulta" type="xs:string" />
<xs:element name="Permisos" type="xs:string" />
</xs:all>
</xs:complexType>
</xs:element>
</xs:schema>
有人有任何想法可以扩展我已经实现的建议吗?
I am using Java 6 and spring-ws to create a very simple web service which receives 2 parameters in the form of a BusquedaRequest Jaxb object and returns the same object.
The object has been created with xjc compiler and I am using Jaxb2Marshaller as the mashaller and GenericMarshallingMethodEndpointAdapter to convert to incoming xml and out going. I had this working when extending the AbstractMarshallingPayloadEndpoint class but when I switch to using the Endpoint and payload annotations it always fails.
The web service starts up fine but when hitting it with a client I recieve this exception.

I have seen response to this question which suggest to compile objects using the xjc compiler which I have done. Also there has been suggestions that the Adaptor hasn't been defined in the spring-ws-servlet.xml, which I have also done. See the spring-ws-servlet.xml defined below:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="busquedaEndpoint" class="package.BusquedaEndpoint" />
<bean class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter">
<constructor-arg ref="marshaller"/>
</bean>
<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="classesToBeBound">
<list>
<value>package.BusquedaRequest</value>
</list>
</property>
</bean>
<bean id="busqueda"
class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
<property name="schema" ref="schema" />
<property name="portTypeName" value="Busqueda" />
<property name="locationUri" value="/BusquedaService/" />
</bean>
<bean id="schema" class="org.springframework.xml.xsd.SimpleXsdSchema">
<property name="xsd" value="/WEB-INF/busqueda.xsd" />
</bean>
<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping"/>
</beans>
The class endpoint is as follows:
package package.busqueda.ws;
import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;
@Endpoint
public class BusquedaEndpoint {
@PayloadRoot(localPart = "BusquedaRequest", namespace = "http://busqueda/schemas")
public BusquedaRequest getResultas( BusquedaRequest aRequest ) {
return aRequest;
}
}
The xsd I generated the BusqeudaRequest object is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
attributeFormDefault="qualified"
xmlns="http://busqueda/schemas"
targetNamespace="http://busqueda/schemas">
<xs:element name="BusquedaRequest">
<xs:complexType>
<xs:all>
<xs:element name="Consulta" type="xs:string" />
<xs:element name="Permisos" type="xs:string" />
</xs:all>
</xs:complexType>
</xs:element>
</xs:schema>
Anyone got any thoughts which extend the suggestions I have already implemented?

当遇到同样的问题时,我发现在 EndPoint 实现中的方法的参数中添加 @RequestPayload 和 @ResponsePayload 注解可以解决问题。
When faced with the same problem, I found that adding @RequestPayload and @ResponsePayload annotations to the parameters of the method in the EndPoint implementation would solve the issue.
@whatsthebeef 也许这是题外话,或者晚了,但我看到问题出在哪里,
从我的角度来看,你使用 Marshaller 的方式很糟糕。
为什么使用classesToBeBound?
如果您使用XJC & JAXB生成过程你真的应该“仅仅”指向包,即
第二件事是,spring上下文应该如何知道你的编组器?我怀念使用适当的 Marshaller 的时光。
这就是我使用当前的 spring-ws 包所做的方式。
顺便说一句,堆栈跟踪告诉您问题出在 *EndpointAdapter 上。
如果对您有帮助,请告诉我。
@whatsthebeef Maybe it's offtopic, or late, but what I see where the problem is,
the way you use Marshaller from my point of view stinks.
Why do you use classesToBeBound?
If you use XJC & JAXB generating process you really should point 'just' to the package i.e.
2nd thing is, how should spring context know about your marshaller? I miss using the appropriate Marshaller.
That's the way i did it with the current spring-ws package.
Btw the stacktrace tells you that the problem is with the *EndpointAdapter.
Please let me know if it helped you.
