Spring Integration 7.0 to 7.1 Migration Guide

TestUtils.getPropertyValue

Spring Integration 7.1 has updated the TestUtils.getPropertyValue() method to use generic type inference instead of requiring an explicit Class parameter.

What Changed

The three-parameter method signature: public static @Nullable T getPropertyValue(Object root, String propertyPath, Class type) has been deprecated in favor of the two-parameter generic method: public static @Nullable T getPropertyValue(Object root, String propertyPath)

Migration Path

Old code (deprecated):

LoadBalancingStrategy strategy = TestUtils.getPropertyValue(channel,     "dispatcher.loadBalancingStrategy", LoadBalancingStrategy.class);Boolean autoStartup = TestUtils.getPropertyValue(adapter,     "autoStartup", Boolean.class);

New code (recommended): Option 1: Type inference with variable assignment (preferred when possible)

LoadBalancingStrategy strategy = TestUtils.getPropertyValue(channel,     "dispatcher.loadBalancingStrategy");Boolean autoStartup = TestUtils.getPropertyValue(adapter, "autoStartup");
Option 2: Explicit generic type parameter (required in some contexts like assertions);
assertThat(TestUtils.<LoadBalancingStrategy>getPropertyValue(channel,     "dispatcher.loadBalancingStrategy"))    .isNotNull();Iterator<BlockingQueueConsumer> iterator =     TestUtils.<Set<BlockingQueueConsumer>>getPropertyValue(this.channel,         "container.consumers")    .iterator();
