This module provides a SpEL function that can be reused and composed in other applications. The function can be used to apply SpEL transformations on data based on a SpEL expression.
The SpelFunctionConfiguration auto-configuration provides the following bean:
spelFunction
You can use spelFunction as a qualifier when injecting.
Once injected, you can use the apply method of the Function to invoke it and get the result.
All configuration properties are prefixed with spel.
For more information on the various options available, please see SpelFunctionProperties.java
See this test suite for examples of how this function is used.
See this README where this function is used to create a Spring Cloud Stream transformer application.
