public abstract class AbstractLoggingInterceptor
extends TransformerObjectSupport
implements EndpointInterceptor

Abstract base class for EndpointInterceptor instances that log a part of a WebServiceMessage. By default, both request and response messages are logged, but this behaviour can be changed using the logRequest and logResponse properties.

Since:

1.0.0

Field Detail

logger

protected transient org.apache.commons.logging.Log logger

The default Log instance used to write trace messages. This instance is mapped to the implementing Class.

Constructor Detail

AbstractLoggingInterceptor

public AbstractLoggingInterceptor()

Method Detail

setLogRequest

public final void setLogRequest(boolean logRequest)

Indicates whether the request should be logged. Default is true.

setLogResponse

public final void setLogResponse(boolean logResponse)

Indicates whether the response should be logged. Default is true.

setLoggerName

public void setLoggerName(String loggerName)

Set the name of the logger to use. The name will be passed to the underlying logger implementation through Commons Logging, getting interpreted as log category according to the logger's configuration.

This can be specified to not log into the category of a class but rather into a specific named category.

LogFactory.getLog(String), org.apache.log4j.Logger#getLogger(String), Logger

handleRequest

public final boolean handleRequest(MessageContext messageContext,
                                   Object endpoint)
                            throws TransformerException

Logs the request message payload. Logging only occurs if logRequest is set to true, which is the default.

Specified by:

handleRequest in interface EndpointInterceptor

Parameters:

messageContext - the message context

endpoint - chosen endpoint to invoke

Returns:

true

Throws:

TransformerException - when the payload cannot be transformed to a string

See Also:

MessageContext.getRequest()

handleResponse

public boolean handleResponse(MessageContext messageContext,
                              Object endpoint)
                       throws Exception

Logs the response message payload. Logging only occurs if logResponse is set to true, which is the default.

Specified by:

handleResponse in interface EndpointInterceptor

Parameters:

messageContext - the message context

endpoint - chosen endpoint to invoke

Returns:

true

Throws:

TransformerException - when the payload cannot be transformed to a string

Exception - in case of errors

See Also:

MessageContext.getRequest(), MessageContext.hasResponse(), MessageContext.getResponse()

handleFault

public boolean handleFault(MessageContext messageContext,
                           Object endpoint)
                    throws Exception

Does nothing by default. Faults are not logged.

Specified by:

handleFault in interface EndpointInterceptor

Parameters:

messageContext - contains both request and response messages, the response should contains a Fault

endpoint - chosen endpoint to invoke

Returns:

true to continue processing of the response interceptor chain; false to indicate blocking of the response handler chain.

Throws:

Exception

afterCompletion

public void afterCompletion(MessageContext messageContext,
                            Object endpoint,
                            Exception ex)

Does nothing by default

Specified by:

afterCompletion in interface EndpointInterceptor

Parameters:

messageContext - contains both request and response messages, the response should contains a Fault

endpoint - chosen endpoint to invoke

ex - exception thrown on handler execution, if any

isLogEnabled

protected boolean isLogEnabled()

Determine whether the logger field is enabled.

Default is true when the "debug" level is enabled. Subclasses can override this to change the level under which logging occurs.

logMessageSource

protected void logMessageSource(String logMessage,
                                Source source)
                         throws TransformerException

Logs the given source to the logger, using the message as a prefix.

By default, this message creates a string representation of the given source, and delegates to logMessage(String).

Parameters:

logMessage - the log message

source - the source to be logged

Throws:

TransformerException - in case of errors

logMessage

protected void logMessage(String message)

Logs the given string message.

By default, this method uses a "debug" level of logging. Subclasses can override this method to change the level of logging used by the logger.

Parameters:

message - the message

getSource

protected abstract Source getSource(WebServiceMessage message)

Abstract template method that returns the Source for the given WebServiceMessage.

Parameters:

message - the message

Returns:

the source of the message
