Why am I getting "Failed to load ApplicationContext" Spring, jUnit with JavaConfig
java, junit, spring
Solution
The stack trace shows the problem
The log message says that you haven't defined MessageDAO:
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.johnathanmarksmith.hellospring.dao.MessageDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
This bean is autowired in MessageServiceImpl which is defined in HelloConfig.class but is not in your config class
Furthermore, when using SpringJUnit4ClassRunner.class you have no need to create the ApplicationContext in your test, just Autowire HelloWorld into your JUnit
Problem
Why am I getting "Failed to load ApplicationContext" Spring, jUnit with JavaConfig Here is my test class: ``` @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes = HelloWorldConfig.class) public class TestApp { @Test public void testBean() { ApplicationContext context = new AnnotationConfigApplicationContext(HelloWorldConfig.class); HelloWorld helloWorld = context.getBean(HelloWorld.class); helloWorld.setMessage("I am in Staten Island, New York"); Assert.assertEquals(helloWorld.getMessage(), "I am in Staten Island, New York"); } } ``` here is the stack trace. ``` java.lang.IllegalStateException: Failed to load ApplicationContext at org.springframework.test.context.CacheAwareContextLoaderDelegate.loadContext(CacheAwareContextLoaderDelegate.java:99) at org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:122) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:109) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.prepareTestInstance(DependencyInjectionTestExecutionListener.java:75) at org.springframework.test.context.TestContextManager.prepareTestInstance(TestContextManager.java:312) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTest(SpringJUnit4ClassRunner.java:211) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner$1.runReflectiveCall(SpringJUnit4ClassRunner.java:288) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.methodBlock(SpringJUnit4ClassRunner.java:284) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:231) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:88) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:71) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:174) at org.junit.runner.JUnitCore.run(JUnitCore.java:157) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:77) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:195) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:63) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120) Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messageService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.johnathanmarksmith.hellospring.dao.MessageDao com.johnathanmarksmith.hellospring.service.MessageServiceImpl.messageDao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.johnathanmarksmith.hellospring.dao.MessageDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
