javax.xml.rpc.server Interface ServletEndpointContext

public interface ServletEndpointContext

The ServletEndpointContext provides an endpoint context maintained by the underlying servlet container based JAX-RPC runtime system. For service endpoints deployed on a servlet container based JAX-RPC runtime system, the context parameter in the ServiceLifecycle.init method is required to be of the Java type javax.xml.rpc.server.ServletEndpointContext.

A servlet container based JAX-RPC runtime system implements the ServletEndpointContext interface. The JAX-RPC runtime system is required to provide appropriate session, message context, servlet context and user principal information per method invocation on the endpoint class.

方法摘要
`HttpSession`	`getHttpSession()` The `getHttpSession` method returns the current HTTP session (as a `javax.servlet.http.HTTPSession`).
`MessageContext`	`getMessageContext()` The method `getMessageContext` returns the `MessageContext` targeted for this endpoint instance.
`ServletContext`	`getServletContext()` The method `getServletContext` returns the `ServletContex`t associated with the web application that contain this endpoint.
`Principal`	`getUserPrincipal()` Returns a `java.security.Principal` instance that contains the name of the authenticated user for the current method invocation on the endpoint instance.
`boolean`	`isUserInRole(String role)` Returns a boolean indicating whether the authenticated user for the current method invocation on the endpoint instance is included in the specified logical "role".

方法详细信息

getMessageContext

MessageContext getMessageContext()

The method getMessageContext returns the MessageContext targeted for this endpoint instance. This enables the service endpoint instance to acccess the MessageContext propagated by request HandlerChain (and its contained Handler instances) to the target endpoint instance and to share any SOAP message processing related context. The endpoint instance can access and manipulate the MessageContext and share the SOAP message processing related context with the response HandlerChain.

返回:: MessageContext; If there is no associated MessageContext, this method returns null.
抛出异常:: IllegalStateException - if this method is invoked outside a remote method implementation by a service endpoint instance.
另请参见:: MessageContext, HandlerChain, Handler

getUserPrincipal

Principal getUserPrincipal()

Returns a java.security.Principal instance that contains the name of the authenticated user for the current method invocation on the endpoint instance. This method returns null if there is no associated principal yet. The underlying JAX-RPC runtime system takes the responsibility of providing the appropriate authenticated principal for a remote method invocation on the service endpoint instance.

返回:: A java.security.Principal for the authenticated principal associated with the current invocation on the servlet endpoint instance; Returns null if there no authenticated user associated with a method invocation.
另请参见:: Principal

getHttpSession

HttpSession getHttpSession()

The getHttpSession method returns the current HTTP session (as a javax.servlet.http.HTTPSession). When invoked by the service endpoint within a remote method implementation, the getHttpSession returns the HTTP session associated currently with this method invocation. This method returns null if there is no HTTP session currently active and associated with this service endpoint. An endpoint class should not rely on an active HTTP session being always there; the underlying JAX-RPC runtime system is responsible for managing whether or not there is an active HTTP session.

The getHttpSession method throws JAXRPCException if invoked by an non HTTP bound endpoint.

返回:: The HTTP session associated with the current invocation or null if there is no active session.
抛出异常:: JAXRPCException - If this method invoked by any non-HTTP bound endpoint
另请参见:: HttpSession

getServletContext

ServletContext getServletContext()

The method getServletContext returns the ServletContext associated with the web application that contain this endpoint. According to the Servlet specification, There is one context per web application (installed as a WAR) per JVM . A servlet based service endpoint is deployed as part of a web application.

返回:: ServletContext
另请参见:: ServletContext

isUserInRole

boolean isUserInRole(String role)

Returns a boolean indicating whether the authenticated user for the current method invocation on the endpoint instance is included in the specified logical "role".

参数:: role - a String specifying the name of the role
返回:: a boolean indicating whether the authenticated user associated with the current method invocation belongs to a given role; false if the user has not been authenticated
