UnsatisfiedDependencyException in SpringMVC and MongoDB project - mongodb

Question

I'm working on a Spring MVC and MongoDB backed application.
My api is working fine,but i would like to create an integration test with Fongo in order to test saving a file and after getting this file by my services.
I have already tried, but when i added #Autowired in my Service class, it returned an UnsatisfiedDependencyException. My test fixture class is the following:
#ActiveProfiles({"test"})
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(
locations = {
"classpath*:config/servlet-config.xml",
"classpath*:config/SpringConfig.xml"})
#WebAppConfiguration
public class IntegrationTest {
#Autowired // returns UnsatisfiedDependencyException
private FileService fileService;
#Before
#Test
public void setUp() throws IOException {
Fongo fongo = new Fongo("dbTest");
DB db = fongo.getDB("myDb");
}
#Test
public void testInsertAndGetFile() throws IOException{
//create a file document in order to save
File file = new File();
file.setId("1");
file.setFileName("test1");
file.setVersionId("1");
//save the file
String id = fileService.storeFile(file);
//get the file
File fileDocument= fileService.getFileById("1");
//check if id is the file id which is expected
assertEquals(fileDocument.getId(), "1");
}
}
and i am receiving this log message:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.ots.openonefilesystem.integration.IntegrationTest': Unsatisfied dependency expressed through field 'fileService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean found for dependency [com.myproject.service.FileService]: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean found for dependency [com.myproject.service.FileService]: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
I'm using xml configuration.
How can i solve my testing error? In my service class FileService i have put #Service, however it seems that Spring expected at least 1 bean which qualifies as autowire candidate.
Also if i remove the #Autowired, the log returns NullpointerException when saving of getting the file,as it was expected.
PS: I use springFramework 4.3.3.RELEASE, spring-data-mongodb 1.9.5.RELEASE
Thank you in advance!

I had to configure Mock Database (Fongo), in order to #Autowired FileService. This, I made it via #ContextConfiguration(classes = {MockDatasourceConfig.class})
So, the correct test fixture class is the following:
#ActiveProfiles({"test"})
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = {MockDatasourceConfig.class})
#WebAppConfiguration
public class IntegrationTest{
#Autowired
private FileService fileService;
#Test
public void testInsertAndGetFile() throws IOException{
//create a file document in order to save
File file = new File();
file.setId("1");
file.setFileName("test1");
file.setVersionId("1");
//save the file and return his id
String id = fileService.storeFileGeneral(file);
//get the file
FileDocument fileDocument= fileService.getFileById(id);
//check that the file isn't null
assertNotNull(fileDocument);
//check if id is the file id which is expected
assertEquals(fileDocument.getId(), id);
assertEquals(fileDocument.getFileName(), "test1");
}
}
and the MockDatasourceConfig class is the following:
#Profile({"test"})
#Configuration
#PropertySource("classpath:mongo.properties")
#ComponentScan(basePackageClasses = {File.class})
#EnableMongoRepositories(basePackageClasses = RepositoryPackageMarker.class)
public class MockDatasourceConfig extends AbstractMongoConfiguration {
#Autowired
Environment env;
#Override
protected String getDatabaseName() {
return env.getProperty("mongo.dbname", "myDb");
}
#Override
public Mongo mongo() throws Exception {
return new Fongo(getDatabaseName()).getMongo();
}
#Bean
public GridFsTemplate gridFsTemplate() throws Exception {
return new GridFsTemplate( mongoDbFactory(),mappingMongoConverter());
}
}
P.S: With helpful advice of #M.Deinum
