Example 1 with TestPerson

use of org.springframework.integration.json.TestPerson in project spring-integration by spring-projects.

the class ParentContextTests method testSpelBeanReferencesInChildAndParent.

/**
 * Verifies that beans in hierarchical contexts get an evaluation context that has the proper
 * BeanResolver. Verifies that the two Foos in the parent context get an evaluation context
 * with the same bean resolver. Verifies that the one Foo in the child context gets a different
 * bean resolver. Verifies that bean references in SpEL expressions to beans in the child
 * and parent contexts work. Verifies that PropertyAccessors are inherited in the child context
 * and the parent's ones are last in the propertyAccessors list of EvaluationContext.
 * Verifies that SpEL functions are inherited from parent context and overridden with the same 'id'.
 * Verifies that child and parent contexts can have different message builders.
 * <p>
 * Only single test method is allowed for 'ParentContext-context.xml',
 * since it relies on static 'evalContexts' variable.
