Major Description
Hi,
since Spring Boot version 2.0.0.M4 I have the following injection problem (can be reproduced by running the AutorwireBugTest in the attached sample project):
I have a Kotlin class Foo which has a primary constructor that expects a parameter of type Bar
@Aggregate
class Foo(param: Bar)
The class also has a default constructor generated by the kotlin-noarg Gradle plugin because of the following configuration in build.gradle:
noArg {
annotation("com.example.autowirebug.Aggregate")
}
Bar is not a Spring bean i.e. autowiring the primary constructor fails in Spring 2.0.0.RC4 :
java.lang.IllegalStateException: Failed to load ApplicationContext at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:125) at org.springframework.test.context.support.DefaultTestContext.getApplicationContext(DefaultTestContext.java:107) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:117) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.prepareTestInstance(DependencyInjectionTestExecutionListener.java:83) at org.springframework.test.context.TestContextManager.prepareTestInstance(TestContextManager.java:242) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTest(SpringJUnit4ClassRunner.java:227) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner$1.runReflectiveCall(SpringJUnit4ClassRunner.java:289) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.methodBlock(SpringJUnit4ClassRunner.java:291) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:246) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:97) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:190) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'foo' defined in file.../Foo.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.example.autowirebug.bar.Bar' available: expected at least 1 bean which qualifies as autowire candidate.

But the same test works in 2.0.0.RC2 because the default constructor is used instead of the primary constructor. Is this behavior intended? Is there a workaround to prevent Spring from picking the wrong constructor.
The problem originally occured when using AxonFramework (http://www.axonframework.org, version, 3.0.5) in combination with Spring Boot and Kotlin. Axon use the following code to load aggregates:
protected T doCreateAggregate(...) { return (T) applicationContext.getBean(prototypeBeanName); }
which now fails with the error described above.
For me it's major problem because it prevents me from using Axon with the latest Spring Boot version and I don't know any workaround.
Thanks and regards,
Andreas
