Provide an expression to use an ExpressionEvaluatingTransformer for the target handler.

Parameters:

expression - the SpEL expression to use.

Returns:

the TransformerSpec

expression

public TransformerEndpointSpec expression(Expression expression)

Provide an expression to use an ExpressionEvaluatingTransformer for the target handler.

Parameters:

expression - the SpEL expression to use.

Returns:

the TransformerSpec

ref
