Java Project: Failed to load ApplicationContext
Looks like you are using maven ( src/main/java) . In this case put the applicationContext.xml file in the src/main/resources directory. It will be copied in the classpath directory and you should be able to access it with
@ContextConfiguration(“/applicationContext.xml”)
From the Spring-Documentation: A plain path, for example “context.xml”, will be treated as a classpath resource from the same package in which the test class is defined. A path starting with a slash is treated as a fully qualified classpath location, for example “/org/example/config.xml”.
So it’s important that you add the slash when referencing the file in the root directory of the classpath.
If you work with the absolute file path you have to use ‘file:C:…’ (if I understand the documentation correctly).
How to fix `Failed to load ApplicationContext` in Spring (Boot) applications · Jamie Tanna
When building Spring (Boot) applications, it’s almost inevitable to be hit with the reliable Failed to load ApplicationContext exception.
This occurs when the Spring Dependency Injection (DI) framework is unable to wire together beans (dependencies for classes).
As noted in Testing that your Spring Boot Application Context is Correctly Configured, one way of catching this, at least before it hits production, is by making sure that you have a test to cover this.
But even with that test, you will still have cases where dependencies are not wired up correctly, and you need to resolve it.
Unfortunately I can’t solve this exactly for you, as there’s very likely to be some context in your stacktrace that, tied to the way your application works, but we can use a few examples to hopefully provide a bit more of an idea of how to work it out for yourself.
The following stacktraces are examples, and won’t match exactly what you have. I’ve also modified them a bit for brevity and broken long lines down so they’re hopefully more readable.
Example project
These examples have been taken from an example Spring Boot app which has been modified to cause these errors.
You can find the classes of relevance below:
ApiController.java import java.util.Set ; import java.util.stream.Collectors ; import me.jvt.hacking.domain.service.ApiService ; import me.jvt.hacking.infrastructure.models.Api ; import me.jvt.hacking.infrastructure.models.ApiResponseContainer ; import org.springframework.web.bind.annotation.GetMapping ; import org.springframework.web.bind.annotation.RequestMapping ; import org.springframework.web.bind.annotation.RestController ; @RestController @RequestMapping ( “/apis” ) public class ApiController { private final ApiService service ; public ApiController ( ApiService service ) { this . service = service ; } @GetMapping public ApiResponseContainer getAll () { Set < Api > apis = service . findAll (). stream () . map ( ApiController :: toApiResponseObject ) . collect ( Collectors . toSet ()); return new ApiResponseContainer ( apis ); } private static Api toApiResponseObject ( me . jvt . hacking . domain . model . Api a ) { return new Api ( a . name (), a . url ()); } }
SpringConfiguration.java import me.jvt.hacking.domain.service.ApiService ; import me.jvt.hacking.domain.service.NoopApiService ; import org.springframework.context.annotation.Bean ; import org.springframework.context.annotation.Configuration ; @Configuration public class SpringConfiguration { @Bean public ApiService apiService () { return new NoopApiService (); } }
NoopApiService.java import java.util.Collections ; import java.util.Set ; import me.jvt.hacking.domain.model.Api ; public class NoopApiService implements ApiService { @Override public Set < Api > findAll () { return Collections . emptySet (); } }
Missing bean definition
One common issue is where we have a Spring bean that hasn’t been defined, but needs to be because another class depends on it.
Stacktrace
Failed to load ApplicationContext java.lang.IllegalStateException: Failed to load ApplicationContext Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘apiController’ defined in file […/build/classes/java/main/me/jvt/hacking/infrastructure/controller/ApiController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘me.jvt.hacking.domain.service.ApiService’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {} … 85 more Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘me.jvt.hacking.domain.service.ApiService’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {} … 103 more
Cause
This was created by the following in the SpringConfiguration class:
@Configuration public class SpringConfiguration {}
In this case, we need to make sure an ApiService is configured, either by adding the Bean configuration to a @Configuration class (which is the current state of the SpringConfiguration , shown at the top of the post), or by using Component Scanning on the NoopApiService :
import java.util.Collections; import java.util.Set; import me.jvt.hacking.domain.model.Api; +import org.springframework.stereotype.Component; +@Component public class NoopApiService implements ApiService { @Override
Too many beans defined
Another common issue is when we’ve got multiple beans defined, and Spring can’t work out how to inject them.
Stacktrace
Failed to load ApplicationContext java.lang.IllegalStateException: Failed to load ApplicationContext Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘apiController’ defined in file […/build/classes/java/main/me/jvt/hacking/infrastructure/controller/ApiController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type ‘me.jvt.hacking.domain.service.ApiService’ available: expected single matching bean but found 2: noopApiService,apiService … 85 more Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type ‘me.jvt.hacking.domain.service.ApiService’ available: expected single matching bean but found 2: noopApiService,apiService … 103 more
Cause
This can be caused by us either having two beans defined like so, or i.e. a mix of @Component s and @Bean s.
import me.jvt.hacking.domain.service.ApiService ; import me.jvt.hacking.domain.service.NoopApiService ; import me.jvt.hacking.domain.service.RealApiService ; import org.springframework.context.annotation.Bean ; import org.springframework.context.annotation.Configuration ; @Configuration public class SpringConfiguration { @Bean public ApiService apiService () { return new NoopApiService (); } @Bean public ApiService another () { return new RealApiService (); } }
Sometimes, this is an indicator of an error in the application, and not needing two of the same thing.
However, this could also be a case of using two classes in the same inheritance hierarchy, such as Jackson’s ObjectMapper and YAMLMapper , in which case we do need two of these.
For instance, we would modify our bean definition in this case like so:
@Configuration public class SpringConfiguration { // … /* this uses the bean with name `apiService`, which in our case is the `NoopApiService` */ @Bean public ApiController apiController ( ApiService apiService ) { return new ApiController ( apiService ); } }
Alternatively, we can be explicit if we don’t want to let it rely on the variable name:
import org.springframework.beans.factory.annotation.Qualifier ; @Configuration public class SpringConfiguration { // … @Bean public ApiController apiController ( @Qualifier ( “apiService” ) ApiService service ) { return new ApiController ( service ); } }
Or we could make it clear that a single bean is the default (and allow consumers who want a specific bean to use one of the other options above):
import org.springframework.beans.factory.annotation.Primary ; @Configuration public class SpringConfiguration { @Bean @Primary public ApiService another () { return new RealApiService (); } // … @Bean public ApiController apiController ( ApiService service ) { return new ApiController ( service ); } }
Missing default value for a property
Another common issue is referencing a Spring property in your bean definition, but then forgetting to add a default value.
Stacktrace
Failed to load ApplicationContext java.lang.IllegalStateException: Failed to load ApplicationContext Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘apiController’ defined in file […/build/classes/java/main/me/jvt/hacking/infrastructure/controller/ApiController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘apiService’ defined in class path resource [me/jvt/hacking/application/SpringConfiguration.class]: Unexpected exception during bean creation; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder ‘example.property’ in value “${example.property}” … Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘apiService’ defined in class path resource [me/jvt/hacking/application/SpringConfiguration.class]: Unexpected exception during bean creation; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder ‘example.property’ in value “${example.property}” … Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder ‘example.property’ in value “${example.property}” …
Cause
In this case, we’ve got the following class:
import me.jvt.hacking.domain.service.ApiService ; import me.jvt.hacking.domain.service.NoopApiService ; import org.springframework.beans.factory.annotation.Value ; import org.springframework.context.annotation.Bean ; import org.springframework.context.annotation.Configuration ; @Configuration public class SpringConfiguration { @Bean public ApiService apiService ( @Value ( “${example.property}” ) String property ) { return new NoopApiService ( property ); } }
But we won’t have provided a default anywhere, whether that’s in an application.properties , application-production.properties , application.yml , environment variable, or on the command-line when running the JAR.
The first solution is to make sure that anywhere that sets configuration, as mentioned above, has the default set.
Alternatively, if this is something we can reasonably default, we could make the following change:
