"A Task Scheduler" is Required when using Spring Integration with MQTT

I have a project where I am using Spring Integration where I am connecting to a broker and then publish-subscribe the messages issued to the broker.
When using #EnableAutoConfiguration and #ComponentScan and #Configuration the application runs fine that is using #SpringBootApplication as a whole. But I don't want to use #EnableAutoConfiguration, this is just a POC project to be integrated into a bigger chunk project. Where, if #EnableAutoConfiguration is used may cause issues for other components which are not needed.
So, how can I resolve this issue?
This is just an excerpt from the project and when done should run normally:
#Configuration
#ComponentScan
public class TestMQTTApp {
public static void main(String[] args) {
SpringApplication.run(TestMQTTApp.class,args);
}
#Bean
public MessageChannel mqttInputChannel() {
return new DirectChannel();
}
#Bean
public MqttPahoMessageDrivenChannelAdapter inbound() {
String clientId = "uuid-" + UUID.randomUUID().toString();
MqttPahoMessageDrivenChannelAdapter adapter =
new MqttPahoMessageDrivenChannelAdapter("tcp://localhost:1883", clientId, "topic1" );
adapter.setCompletionTimeout(5000);
adapter.setConverter(new DefaultPahoMessageConverter());
adapter.setQos(1);
adapter.setOutputChannel(mqttInputChannel());
return adapter;
}
#Bean
public EmbeddedServletContainerFactory servletContainer() {
TomcatEmbeddedServletContainerFactory factory =
new TomcatEmbeddedServletContainerFactory();
return factory;
}
}
Error is as follows:
org.springframework.context.ApplicationContextException: Failed to start bean 'inbound'; nested exception is java.lang.IllegalStateException: A 'taskScheduler' is required

I am having trouble scanning the packages for the task scheduler although nowhere in the code have I mentioned this.
Additional Information for POM:
Spring Boot - 1.5.1.RELEASE
Spring Framework Version - 4.3.20.RELEASE
Spring Integration - 4.3.20.RELEASE

You are missing #EnableIntegration. That one adds a broader Spring Integration infrastructure , included a required TaskScheduler. See docs foer more info: https://docs.spring.io/spring-integration/docs/current/reference/html/overview.html#configuration-enable-integration

#Autowire JpaRepository interface class error qualifying bean

I am configuring my Spring MVC project with deploying on Tomcat Local Server (tomcat 9) on Intellij Idea.Please look at the code and help me identify what I am missing. I cant fing any mistakes.
Error happens because of trying to create an interface object. But in Spring boot all is OK.
public class AppInit extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {return new Class<?>[]{WebConfig.class};
}
#Override
protected Class<?>[] getServletConfigClasses() {return new Class<?>[]{WebConfig.class};
}
#Override
protected String[] getServletMappings() {return new String[]{"/"};}
}
configs
#Configuration
#ComponentScan("BeNi")
public class WebConfig extends WebMvcConfigurerAdapter {
}
#Controller
#RequestMapping("/test")
controller
public class MainController extends HttpServlet {
#Autowired private PersonServiceImpl test;
#RequestMapping(method = RequestMethod.GET)
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("tested");
test.addPerson(new Person());
}
}
my entity
#Entity
public class Person {
#Id
#GeneratedValue(generator = "increment")
#GenericGenerator(name= "increment", strategy= "increment")
private Long id;
private String name;
public Person(String name) {this.name = name;}
public Person(){}
public String getName() {return name;}
public void setName(String name) {this.name = name;}
public Long getId() {return id;}
public void setId(Long id) {this.id = id;}
}
my repository
#Repository
public interface PersonRepository extends JpaRepository<Person,Long> {
}
service
#Service
public interface PersonService {
void addPerson(Person person);
}
service implementation
#Service
public class PersonServiceImpl implements PersonService {

Compilation is always success, but deploying crashes with an error

According to a stacktrace info the initial exception is:
Caused by:

qualifying bean of type 'BeNi.repository.PersonRepository' available:
expected at least 1 bean which qualifies as autowire candidate.
Dependency annotations:
{#org.springframework.beans.factory.annotation.Autowired(required=true)}
It means that Spring can not find a repository location, so I suppose you should enable repository discovering for a package where repositories are:
#Configuration
#ComponentScan("BeNi")
#EnableJpaRepositories("BeNi.repository")
public class WebConfig extends WebMvcConfigurerAdapter {
}
UPD
You also must configure a DataSource bean to allow Spring configure an EntityManagerFactory. Please follow the link below for more details. Spring doc

Dont use #Service annotation in interfaces, this annotation is for classes, remove from interface PersonService , and #Repository is not needed for PersonRepositoryas you are already extending JpaRepository.

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured. SPRING

I've already checked all the similar questions and every answer says that I need to specify a driverClassName which I already do. Here is my application.yml:
spring:
application:
name: cibus-backend
datasource:
driverClassName: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/Cibus?useSSL=true
username: root
password: 1234567890

Am I missing something? The weird thing is that a classmate of mine who has the same code can start the app perfectly well. This is why I think it has something to do with the path. Maybe spring isn't accessing the yml file. I included it in src.main.resources which is the default place where Spring looks for it.

To Fix the
Cannot determine embedded database error
Try Excluding the auto configuration of DataSource in the Spring Boot application class. You can do this using EnableAutoConfiguration
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
#SpringBootApplication
public class {...}

Also worth mentioning is what this looks like in Kotlin:
#SpringBootApplication(
exclude = [DataSourceAutoConfiguration::class]
)
class Launcher
...
... for those of us who write kotlin but who came here with the same error.

The solution that worked for me is the following
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
#SpringBootApplication
public class ApiApplication {
public static void main(String[] args) {
SpringApplication.run(ApiApplication.class, args);
}
}

you need to enable autoconfig to jdbc in spring boot
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
add these lines and import below libraries
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
this works fine.

Adding below annotation worked for me:
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
#SpringBootApplication
public class ApiApplication {
public static void main(String[] args) {
SpringApplication.run(ApiApplication.class, args);
}
}

Make sure your packaging attribute in pom.xml is war. It worked perfectly for me.
<packaging>war</packaging>

Getting a SessionFactory in Spring Boot 2.0 / Hibernate 5

I was using HibernateJpaSessionFactoryBean in Spring Boot 1.5.x to get a session factory bean for my sessions. Since that's deprecated now, I'm trying to use the session factory by unwrapping in an EntityManagerFactory. But, I can't get EntityManagerFactory to be autowired. There's no bean defining it.
What do I need to do to wire in an EntityManagerFactory? entityManagerFactory remains null.
/**
* A class to hold necessary data access beans.
*/
#Configuration
#EnableTransactionManagement
public class DataBeans {
#Autowired
private EntityManagerFactory entityManagerFactory;
/**
* This bean needs to be wired in so that a SessionFactory can be wired in to other data access beans.
*
* #return a session factory bean
*/
#Bean
public SessionFactory sessionFactoryProvider() {
return entityManagerFactory.unwrap(SessionFactory.class);
}
}
#SpringBootApplication
public class AppBootMain {
public static void main(String[] args) {
SpringApplication.run(AppBootMain.class, args);
}
}
application.properties:
spring.datasource.driverClassName=org.hsqldb.jdbc.JDBCDriver
spring.datasource.url=jdbc:hsqldb:mem:student_db
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.database-platform=org.hibernate.dialect.HSQLDialect
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=create-drop
# this ensures that a session factory bean is available
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate5.SpringSessionContext
Note: i tried changing the current_session_context_class to specify hibernate5 in the package, but no success.

I tried putting EntityManagerFactory as a paraemter to the bean method that creatrs teh session factory, but it failed due to circular dependency.
#Bean
public SessionFactory sessionFactoryProvider(EntityManagerFactory entityManagerFactory) {
return entityManagerFactory.unwrap(SessionFactory.class);
}

I encountered the same problem when upgrade from 1.5 to 2.1.3 and resolved by getting the Session / SessionFactory in the Dao class instead of autowire when spring init.
Following is an example:
Remove the DataBeans in you example
In the Dao classes use following to get the Session:
#Repository
#Transactional
public class XXXDao {
#Autowired
private EntityManager entityManager;
private Session getSession() {
return entityManager.unwrap(Session.class);
}
...
}
If you really need the SessionFactory, use following coding and beware that the you might need to handle the transaction manually.
#Repository
public class XXXDao {
#Autowired
private EntityManagerFactory entityManagerFactory;
private SessionFactory getSessionFactory() {
return entityManagerFactory.unwrap(SessionFactory.class);
}
...
}
I would suggest you check also the
Spring boot hibernate no transaction is in progress for the transaction issue

I did the same as you but without #EnableTransactionManagement.
Here my class and properties.
#Configuration
public class SessionFactoryConfiguration {
#Autowired
private EntityManagerFactory entityManagerFactory;
#Bean
public SessionFactory getSessionFactory() {
return entityManagerFactory.unwrap(SessionFactory.class);
}
}
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.format_sql=false
spring.jpa.properties.hibernate.jdbc.batch_size=10
spring.jpa.properties.hibernate.id.new_generator_mappings=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate5.SpringSessionContext
Adding #EnableTransactionManagement means Transaction will be enabled but you have to configure it via PlatformTransactionManager. Spring autoconfiguration will do it so you don't have to declare it.

CDI Logger Injection error in Junit test but not on Wildfly server

I come across a strange behavior. I looked for a possible explanation but I did not find (always the same types of answers).
My implementation is perfectly deployed under WildFly 10.x and the Logger works perfectly. I created very classic elements of CDI encapsulation of a Logger production bean. As shown it works well in deployed mode. I deleted the logging subsystem provided by Wildfly to use as logback and the configuration contained in the war file.
The worry is during a unit test. It tells me that the injected logger is null. It seems to me both normal but odd.
The CDI Logger Producer:
public class LoggerProducer {
#Produces
public Logger createLogger(InjectionPoint injectionPoint) {
return LoggerFactory.getLogger(injectionPoint.getBean().getBeanClass());
}
}
The implementation of a specific interceptor :
#Interceptor
#RestOperation
public class RestOperationInterceptor {
#Inject
private Logger logger;
#AroundInvoke
public Object interceptRestOperation(InvocationContext context) throws Exception {
Preconditions.checkNotNull(context);
logger.info("Context parameters : {}", MoreObjects.toStringHelper(context.getParameters()).toString());
return context.proceed();
}

This code works well on my Wildfly Server.
The bean discovery (beans.xml), only for this interceptor and to avoid #Dependent annotation on LoggerProducer.class :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/beans_1_0.xsd"
bean-discovery-mode="all">
<interceptors>
<class>fr.hoag.interceptors.RestOperationInterceptor</class>
</interceptors>
</beans>
But this unit test...
#RunWith(CdiRunner.class)
public class RestInterceptorTest {
#Produces /* #Mock/#Inject etc. */
Logger logger;
#Test
public void should_intercept_rest_request() throws Exception {
InvocationContext context = mock(InvocationContext.class);
when(context.getParameters()).thenReturn(new Object[]{1,2,3});
when(context.proceed()).thenReturn("test");
RestOperationInterceptor interceptor = new RestOperationInterceptor();
assertThat(interceptor.interceptRestOperation(context)).isEqualTo("test");
}
}
The result is (Line 27 of RestOperationInterceptor is about the logger, context and context.getParameters() are not null):
java.lang.NullPointerException

The WELD stacktrace : Logger seems to be well produced.
11:18:38.388 [main] DEBUG org.jboss.weld.Bootstrap - WELD-000106: Bean: Producer Field [Logger] with qualifiers [#Any #Default] declared as [[UnbackedAnnotatedField] #Produces RestInterceptorTest.logger]
I think something is missing in bean discovery for the LoggerProducer in CDIUnit. What could i forget ?
Thanks you in advance.
