Example 1 with SpelExpression

use of org.springframework.expression.spel.standard.SpelExpression in project spring-framework by spring-projects.

the class PropertyAccessTests method testAccessingOnNullObject.

/**
	 * The standard reflection resolver cannot find properties on null objects but some
	 * supplied resolver might be able to - so null shouldn't crash the reflection resolver.
