 String jsonPathExpression)
                                                    throws ConfigurationException

Compile a JsonPath from the jsonPathExpression parameter, if it's not null. If jsonPathExpression is null, return null.

Parameters:

jsonPathExpression - JSON Path Expression to compile. May be null.

Returns:

JsonPath compiled from the jsonPathExpression, or null if jsonPathExpression was null.

Throws:

ConfigurationException - If there was any exception in trying to compile the jsonPathExpression, throw a ConfigurationException.

                                            throws JsonException

Evaluate given JsonPath against the input Message and return a single scalar value, represented as String.

• If the expression evaluation results in a JsonArray, the first value of the array is returned.
• If the expression evaluation results in a JsonObject, an empty string is returned to indicate a non-scalar value was found.
• If the expression evaluation does not result in any value found, then null is returned to indicate that there was no result.

Parameters:

jsonPath - JsonPath expression to evaluate

message - Message from which to extract data

Returns:

Single scalar value from the message, an empty string if the value could not be reduced to a scalar, or null if there was no result.

Throws:

JsonException - If an exception occurred evaluating the expression a JsonException is thrown.
