I use Spring-Boot for my app, and I want to Autowired jobService of Spring Batch Admin to manage batch job myself.
But when i use this
#Autowied
Jobservice jobService;
It throws exception
No qualifying bean of type [org.springframework.batch.admin.service.JobService] 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)}
How can I fix this exception. Am I need to configure any thing about jobService.
I researched and try this
#Bean
public JobService jobService() throws Exception {
SimpleJobServiceFactoryBean factory = new SimpleJobServiceFactoryBean();
return factory.getObject();
}
But seem like not work and it throws another exception. Do I configure wrong in something?
SimpleJobServiceFactoryBean needs to be populated with other mandatory properties to create a Jobservice.
#Bean
public JobService jobService() throws Exception {
SimpleJobServiceFactoryBean factoryBean = new SimpleJobServiceFactoryBean();
factoryBean.setDataSource(new EmbeddedDatabaseBuilder().build());
factoryBean.setJobRepository((JobRepository) new MapJobRepositoryFactoryBean(
new ResourcelessTransactionManager()).getObject());
factoryBean.setJobLocator(new MapJobRegistry());
factoryBean.setJobLauncher(new SimpleJobLauncher());
factoryBean.afterPropertiesSet();
return factoryBean.getObject();
}

#DataJpaTest
class DataJpaVerificationTest {
#Autowired
private JdbcTemplate template;
#Test
public void testTemplate() {
assertThat(template).isNotNull();
}
}
When I run this test I get the following error:
java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by:
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'kafkaConfig' defined in file
[***\config\KafkaConfig.class]:

nested exception is
org.springframework.beans.factory.NoSuchBeanDefinitionException: No
qualifying bean of type
'org.springframework.boot.autoconfigure.kafka.KafkaProperties'
available: expected at least 1 bean which qualifies as autowire
candidate. Dependency annotations: {}
where KafkaConfig class is a part of my application (app read data from Kafka and saves data to DB) and looks like:
#Configuration
#RequiredArgsConstructor
public class KafkaConfig {
private final KafkaProperties kafkaProperties;
#Bean
public Properties consumerProperties() {
Properties props = new Properties();
props.putAll(this.kafkaProperties.buildConsumerProperties());
return props;
}
}
Based on information that I googled about DataJpaTest annotation:
created application context will not contain the whole context needed
for our Spring Boot application, but instead only a “slice” of it
containing the components needed to initialize any JPA-related
components like our Spring Data repository.
So the question is: why Spring tries to load to the context Kafka specific bean for DataJpaTest?
I created a custom OAuth2AuthorizationRequestResolver that is initialized with a ClientRegistrationRepository and String authorizationRequestBaseUri. It is based on this implementation here https://www.baeldung.com/spring-security-custom-oauth-requests.
I initialize my custom resolver in my WebSecurityConfig.
#Autowired
private InMemoryClientRegistrationRepository inMemoryClientRegistrationRepository;
#Override
protected void configure(HttpSecurity http) throws Exception {
http.
// ...
.oauth2Login(oAuth2LoginConfigurer -> oAuth2LoginConfigurer
.authorizationEndpoint()
.authorizationRequestResolver(new CustomtAuthorizationRequestResolver(inMemoryClientRegistrationRepository, "/oauth2/authorization"))
)
// ...
}
When I run the app, the InMemoryClientRegistrationRepository is correctly autowired and loads my clients from my application.yml.
In my test, I want to have the same InMemoryClientRegistrationRepository with the clients loaded from my application.yml. However, I cannot find a way to inject / autowire the InMemoryClientRegistrationRepository.
#SpringBootTest
#ContextConfiguration(classes = { TestConfiguration.class, InMemoryClientRegistrationRepository.class },
initializers = ConfigFileApplicationContextInitializer.class)
#ActiveProfiles("test")
public class CustomAuthorizationRequestResolverTests {
#Autowired
private InMemoryClientRegistrationRepository inMemoryClientRegistrationRepository;
#Test
public void firstTest() {
HttpServletRequest request = new MockHttpServletRequest();
OAuth2AuthorizationRequestResolver resolver = new CustomAuthorizationRequestResolver(inMemoryClientRegistrationRepository, "/oauth2/authorization");
resolver.resolve(request, "client");
// ...
}
}
With this code I get
Unsatisfied dependency expressed through field 'inMemoryClientRegistrationRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.security.oauth2.client.registration.InMemoryClientRegistrationRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
I can only find tests that use InMemoryClientRegistrationRepository by building it separately in the test and I cannot find any tests that load the clients from the application.yml. What do I have to do so that I can use my InMemoryClientRegistrationRepository with the values from my application.yml in my tests?
Update
I use the default TestConfiguration here and ConfigFileApplicationContextInitializer here classes from spring-boot-test-2.3.1.
I have some java objects coming from external library which I need to inject in my spring project. Problem is the classes from library is not aware of any spring api's
If I inject the beans from library to Service using #Autowired I am getting org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type
Following is my service class
#Path("/test")
public class TestService {
#Autowired
SomeOtherClass service;
#GET
public Response get(){
return Response.ok(service.someMethod()).build();
}
}
and following is my class from library which is not aware of spring
public class SomeOtherClass {
public String someMethod(){
return "Data from library";
}
}
When I invoke my service I get exception as
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.example.SomeOtherClass' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
Is there are way in spring to inject a plain Java Object similar to that of injection in **CDI**?
There is one option to define applicationcontext.xml and define SomeOtherClass in xml and use getBean, but I don't want to do that. Is there any other option?
Note:
Following options cannot be considered because I have100's of classes coming from library
Cannot use applicationcontext.xml
Cannot #Configuration #Bean to produce beans.
You could use the #Configuration and #Bean annotations as follows -
Create a new class:
#Configuration
public class AppConfig {
#Bean
SomeOtherClass someOtherClassBean(){ return new SomeOtherClass();}
}
Now the auto wiring shall work.
What it does, is actually creating a bean and letting Spring know about it.
Maybe try adding the beans programatically to the IoC container:
Add Bean Programmatically to Spring Web App Context
You need to find all the classes you want to instantiate and use one of the methods in the linked question.
You can use reflection to add Bean definitions programatically.
#Override
public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry registry) throws BeansException {
Reflections ref = new Reflections(new ConfigurationBuilder()
.setScanners(new SubTypesScanner(false /* don't exclude Object.class */), new ResourcesScanner())
.setUrls(ClasspathHelper.forPackage(PACKAGE_NAME))
.filterInputsBy(new FilterBuilder().include(FilterBuilder.prefix(PACKAGE_NAME))));
ref.getSubTypesOf(Object.class).stream()
.forEach(clazz -> {
logger.info("Defining pojo bean: {} -> {}", Introspector.decapitalize(clazz.getSimpleName()), clazz.getCanonicalName());
registry.registerBeanDefinition(Introspector.decapitalize(clazz.getSimpleName()),
BeanDefinitionBuilder.genericBeanDefinition(clazz).getBeanDefinition());
});
}
Subsequently, these beans can be #Autowired elsewhere. See Gist: https://gist.github.com/ftahmed/a7dcdbadb8bb7dba31ade463746afd04
I have a Spring Boot Batch application that I'm writing integration tests against. However, I'm getting the following error about the EntityManagerFactoryBuilder bean missing when running a test:
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'entityManagerFactory' defined in com.example.DatabaseConfig: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder]: :
No qualifying bean of type [org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
Dependency annotations: {}; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:

at org.springframework.beans.factory.support.ConstructorResolver.createArgumentArray(ConstructorResolver.java:749) ~[spring-beans-4.2.4.RELEASE.jar:4.2.4.RELEASE]
My understanding is that Spring Boot provides the EntityManagerFactoryBuilder bean on application startup. How can I have the EntityManagerFactoryBuilder provided when running tests?
Here's my test code:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = {DatabaseConfig.class, BatchConfiguration.class})
#TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
StepScopeTestExecutionListener.class })
public class StepScopeTestExecutionListenerIntegrationTests {
#Autowired
private FlatFileItemReader<Foo> reader;
#Rule
public TemporaryFolder testFolder = new TemporaryFolder();
public StepExecution getStepExection() {
StepExecution execution = MetaDataInstanceFactory.createStepExecution();
return execution;
}
#Test
public void testGoodData() throws Exception {
//some test code
}
Here's the DatabaseConfig class:
#Configuration
#EnableJpaRepositories(basePackages={"com.example.repository"},
entityManagerFactoryRef="testEntityManagerFactory",
transactionManagerRef = "testTransactionManager")
public class DatabaseConfig {
#Bean
public LocalContainerEntityManagerFactoryBean testEntityManagerFactory(EntityManagerFactoryBuilder builder) {
return builder
.dataSource(dataSource())
.packages("com.example.domain")
.persistenceUnit("testLoad")
.build();
}
#Bean
#ConfigurationProperties(prefix="spring.datasource")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
#Bean
public PlatformTransactionManager testTransactionManager(EntityManagerFactory testEntityManagerFactory) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(testEntityManagerFactory);
return transactionManager;
}
}
When (integration) testing a Spring Boot application that is what you should do. The #SpringApplicationConfiguration is intended to take your application class (the one with the #SpringBootApplication annotation) as it will then be triggered to do much of the same auto configuration as a regular Spring Boot application.
You are only including 2 configuration classes and as such no auto configuration will be done.
I'd like to create an autowired bean in a Dao class in order to do logging opperations. My way was hitherto static final statement like this:
private static final Log log = LogFactory.getLog(LoggedClass.class);
But now I'm trying to use IoC to turn classes decoupled.
If just add configuration in pom.xml and try to do sth like
#Autowired
Log log;
I receive an error message:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'funciDaoImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.apache.commons.logging.Log br.com.bb.dirco.dao.impl.FunciDaoImpl.log; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'log' defined in class path resource [com/company/project/util/PersistenceConfig.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [java.lang.Class]: : No qualifying bean of type [java.lang.Class] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

In order to get a logger, I had to provide a class to getLog method on LogFactory class and attribute it to Log instance. There's a way to do it using #Autowired Spring IoC? Thanks!
You can inject only those objects which are managed/created by Spring container. You have to register your bean (or factory method creating the bean) with container (with annotations like #Component/#Singleton/... or directly in xml)
In your case it's not very applicable since you have to have many different types (for every class) of logger objects provided by Spring and then when you inject they would have to be identified by different name/type for every class.
P.S. I don't see any problem using it the way you use it now
Where I work we have implemented support for #Autowired SLF4J Loggers using Springs BeanPostProcessor.
First you need to define an Logger placeholder bean in your application context. This bean is going to be injected by Spring into all bean with a #Autowired Logger field.
#Configuration
public class LoggerConfig {
#Bean
public Logger placeHolderLogger() {
return PlaceHolder.LOGGER;
}
#Bean
public AutowiredLoggerBeanPostProcessor loggerPostProcessor() {
return new AutowiredLoggerBeanPostProcessor();
}
}
Then you an AutowiredLoggerBeanPostProcessor which inspects all beans, indetify bean that contain Logger fields annotated with #Autowired (at this point should contain a reference to the Logger placeholder bean), create a new Logger for the partilcar bean an assigned it to the fields.
#Component
public class AutowiredLoggerBeanPostProcessor implements BeanPostProcessor, PriorityOrdered {
#Override
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
attachLogger(bean);
return bean;
}
#Override
public Object postProcessBeforeInitialization(final Object bean, String beanName) throws BeansException {
attachLogger(bean);
return bean;
}
private void attachLogger(final Object bean) {
ReflectionUtils.doWithFields(bean.getClass(), new FieldCallback() {
public void doWith(Field field) throws IllegalArgumentException, IllegalAccessException {
if (Logger.class.isAssignableFrom(field.getType()) &&
(field.isAnnotationPresent(Autowired.class) ||
field.isAnnotationPresent(Inject.class))) {
ReflectionUtils.makeAccessible(field);
if (field.get(bean) == PlaceHolder.LOGGER) {
field.set(bean, LoggerFactory.getLogger(bean.getClass()));
}
}
}
});
}
