Spring Web Services offer another endpoint with which you can aggregate multiple handling into one
controller, thus grouping functionality together. This model is based on annotations, so you can use it only with
Java 5 and higher. Here is an example that uses the same marshalled objects as above:
package samples;
import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;
@Endpoint
public class AnnotationOrderEndpoint {
private final OrderService orderService;
public AnnotationOrderEndpoint(OrderService orderService) {
this.orderService = orderService;
}
@PayloadRoot(localPart = "orderRequest", namespace = "http://samples")
public Order getOrder(OrderRequest orderRequest) {
return orderService.getOrder(orderRequest.getId());
}
@PayloadRoot(localPart = "order", namespace = "http://samples")
public void order(Order order) {
orderService.createOrder(order);
}
}
By annotating the class with @Endpoint, you mark it as a Spring-WS endpoint. Because the endpoint class can
have multiple request handling methods, we need to instruct Spring-WS which method to invoke for which
request. This is done using the @PayloadRoot annotation: the getOrder method will be invoked for requests
with a orderRequest local name and a http://samples namespace URI; the order method for requests with a
order local name. For more information about these annotations, refer to Section 5.4.3,
“MethodEndpointMapping”.

This web application context contains Spring-WS beans. The beans
defined in this context are automatically detected by Spring-WS,
similar to the way Controllers are picked up in Spring Web MVC.

<bean
class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping">
<description>
Detects @PayloadRoot annotations on @Endpoint bean methods.
The MarshallingAirlineEndpoint has such annotations. It uses
two interceptors: one that logs the message payload, and the
other validates it accoring to the 'airline.xsd' schema
file.

<bean id="echo"
class="org.springframework.ws.wsdl.wsdl11.DynamicWsdl11Definition">
<description>
This bean definition represents a WSDL definition that is
generated at runtime, based on the builder defined below. It
can be retrieved by going to /echo/echo.wsdl (i.e. the bean
name corresponds to the filename).
</description>
<property name="builder">
<description>
The builder creates a WSDL from the 'echo.xsd' schema.
It detects all elements that ends with 'Request', finds
corresponding 'Response' messages, and creates an
operation based on that. All operations are put in a
portType with name 'Echo', and binding and service are
created.

也就是說用spring開發webservice需要配置一下文件：
1.EndPoint，如果使用標記的話，就可以不用繼承任何類
2.EndpointMapping，Detects @PayloadRoot annotations on @Endpoint bean methods.
3.DynamicWsdl11Definition。動態生成WSDL
如果使用JAXB作為Object和XML的映射，那么還需要
4.Marshaller一般為Jaxb2Marshaller
5.如果是使用的標記的話，還需要MarshallingMethodEndpointAdapter，一般現在使用
GenericMarshallingMethodEndpointAdapter
