I'm using Spring Boot to bootstrap a spring-data-neo4j application. My unit tests (with no dependencies injected) run fine, but when I try to run an integration test with an @Autowired
dependency on a @Service
-annotated class, it's failing on a NoSuchBeanDefinitionException
.
It seems like the context isn't being loaded in the unit test for some reason, but I've annotated the test with @SpringApplicationConfiguration(classes = AppConfig.class)
- is there something else I need to do here?
Configuration class
@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = "net.foo.bar")
@EnableNeo4jRepositories(basePackages = "net.foo.bar.repo")
public class AppConfig extends Neo4jConfiguration {
public AppConfig() {
setBasePackage("net.foo.bar");
}
@Bean(destroyMethod = "shutdown")
@Scope(BeanDefinition.SCOPE_SINGLETON)
public GraphDatabaseService graphDatabaseService() {
return new GraphDatabaseFactory().newEmbeddedDatabase(filePath);
}
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(AppConfig.class, args);
}
}
Service class:
package net.foo.bar.core.service
@Service
public class PostService implements EntityService<PostDAO,Post> {
@Autowired
Neo4jTemplate template;
//...
//don't think anything else here is relevant
}
Test class:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = AppConfig.class)
public class PostTests {
@Autowired
PostService postService;
@Test
public void someTest(){
postService.doSomething();
//...
}
}
Stack trace:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'net.foo.bar.PostTests': ....
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [net.foo.bar.core.service.PostService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Update:
As a workaround, rather than autowiring my service directly, I tried autowiring a reference to the ApplicationContext
and instantiating my service through a call to getBeanOfType()
in my setUp()
method:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Epublic.class)
public class PostTests {
@Autowired
ApplicationContext ctx;
PostService service;
@Before
public void setUp() {
service = ctx.getBean("postServiceImpl", PostService.class);
}
}
This is working, but I feel like I'm hitting the target but missing the point here...
You don't have basePackages
for @ComponentScan
. You have only for NeojConfiguration
@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = { "net.foo.bar" })
@EnableNeo4jRepositories(basePackages = "net.foo.bar.repo")
public class AppConfig extends Neo4jConfiguration {
public AppConfig() {
setBasePackage("net.foo.bar");
}
@Bean(destroyMethod = "shutdown")
@Scope(BeanDefinition.SCOPE_SINGLETON)
public GraphDatabaseService graphDatabaseService() {
return new GraphDatabaseFactory().newEmbeddedDatabase(filePath);
}
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(AppConfig.class, args);
}
}
