Endpoint (Java EE 5 SDK)

javax.xml.ws Class Endpoint

java.lang.Object
  javax.xml.ws.Endpoint

public abstract class Endpoint

extends Object

A Web service endpoint.

Endpoints are created using the static methods defined in this class. An endpoint is always tied to one Binding and one implementor, both set at endpoint creation time.

An endpoint is either in a published or an unpublished state. The publish methods can be used to start publishing an endpoint, at which point it starts accepting incoming requests. Conversely, the stop method can be used to stop accepting incoming requests and take the endpoint down. Once stopped, an endpoint cannot be published again.

An Executor may be set on the endpoint in order to gain better control over the threads used to dispatch incoming requests. For instance, thread pooling with certain parameters can be enabled by creating a ThreadPoolExecutor and registering it with the endpoint.

Handler chains can be set using the contained Binding.

An endpoint may have a list of metadata documents, such as WSDL and XMLSchema documents, bound to it. At publishing time, the JAX-WS implementation will try to reuse as much of that metadata as possible instead of generating new one based on the annotations present on the implementor.

Endpoint

public Endpoint()

create

public static Endpoint create(Object implementor)

Creates an endpoint with the specified implementor object. If there is a binding specified via a BindingType annotation then it MUST be used else a default of SOAP 1.1 / HTTP binding MUST be used.

The newly created endpoint may be published by calling one of the javax.xml.ws.Endpoint#publish(String) and javax.xml.ws.Endpoint#publish(Object) methods.

参数:

implementor - The endpoint implementor.

返回:

The newly created endpoint.

create

public static Endpoint create(String bindingId,
                              Object implementor)

Creates an endpoint with the specified binding type and implementor object.

The newly created endpoint may be published by calling one of the javax.xml.ws.Endpoint#publish(String) and javax.xml.ws.Endpoint#publish(Object) methods.

参数:

bindingId - A URI specifying the binding to use. If the bindingID is null and no binding is specified via a BindingType annotation then a default SOAP 1.1 / HTTP binding MUST be used.

implementor - The endpoint implementor.

返回:

The newly created endpoint.

getBinding

public abstract Binding getBinding()

Returns the binding for this endpoint.

返回:

The binding for this endpoint

getImplementor

public abstract Object getImplementor()

Returns the implementation object for this endpoint.

返回:

The implementor for this endpoint

publish

public abstract void publish(String address)

Publishes this endpoint at the given address. The necessary server infrastructure will be created and configured by the JAX-WS implementation using some default configuration. In order to get more control over the server configuration, please use the javax.xml.ws.Endpoint#publish(Object) method instead.

参数:

address - A URI specifying the address to use. The address must be compatible with the binding specified at the time the endpoint was created.

抛出异常:

IllegalArgumentException - If the provided address URI is not usable in conjunction with the endpoint's binding.

IllegalStateException - If the endpoint has been published already or it has been stopped.

publish

public static Endpoint publish(String address,
                               Object implementor)

Creates and publishes an endpoint for the specified implementor object at the given address.

The necessary server infrastructure will be created and configured by the JAX-WS implementation using some default configuration. In order to get more control over the server configuration, please use the javax.xml.ws.Endpoint#create(String,Object) and javax.xml.ws.Endpoint#publish(Object) method instead.

参数:

address - A URI specifying the address and transport/protocol to use. A http: URI must result in the SOAP 1.1/HTTP binding being used. Implementations may support other URI schemes.

implementor - The endpoint implementor.

返回:

The newly created endpoint.

publish

public abstract void publish(Object serverContext)

Publishes this endpoint at the provided server context. A server context encapsulates the server infrastructure and addressing information for a particular transport. For a call to this method to succeed, the server context passed as an argument to it must be compatible with the endpoint's binding.

参数:

serverContext - An object representing a server context to be used for publishing the endpoint.

抛出异常:

IllegalArgumentException - If the provided server context is not supported by the implementation or turns out to be unusable in conjunction with the endpoint's binding.

IllegalStateException - If the endpoint has been published already or it has been stopped.

stop

public abstract void stop()

Stops publishing this endpoint. If the endpoint is not in a published state, this method has not effect.

isPublished

public abstract boolean isPublished()

Returns true if the endpoint is in the published state.

返回:

true if the endpoint is in the published state.

getMetadata

public abstract List<Source> getMetadata()

Returns a list of metadata documents for the service.

返回:

List<javax.xml.transform.Source> A list of metadata documents for the service

setMetadata

public abstract void setMetadata(List<Source> metadata)

Sets the metadata for this endpoint.

参数:

metadata - A list of XML document sources containing metadata information for the endpoint (e.g. WSDL or XML Schema documents)

抛出异常:

IllegalStateException - If the endpoint has already been published.

getExecutor

public abstract Executor getExecutor()

Returns the executor for this Endpointinstance. The executor is used to dispatch an incoming request to the implementor object.

返回:

The java.util.concurrent.Executor to be used to dispatch a request.

另请参见:

Executor

setExecutor

public abstract void setExecutor(Executor executor)

Sets the executor for this Endpoint instance. The executor is used to dispatch an incoming request to the implementor object. If this Endpoint is published using the publish(Object) method and the specified server context defines its own threading behavior, the executor may be ignored.

参数:

executor - The java.util.concurrent.Executor to be used to dispatch a request.

抛出异常:

SecurityException - If the instance does not support setting an executor for security reasons (e.g. the necessary permissions are missing).

Executor

getProperties

public abstract Map<String,Object> getProperties()

Returns the property bag for this Endpoint instance.

返回:

Map<String,Object> The property bag associated with this instance.

setProperties

public abstract void setProperties(Map<String,Object> properties)

Sets the property bag for this Endpoint instance.

参数:

properties - The property bag associated with this instance.
