For some reason, Spring isn't able to auto wire the Repo into the Service Class. I've gone through every SO thread that deals with similar problems and I couldn't solve my problem,
here is my code.
public interface WProcessItemDetailsRepo extends PagingAndSortingRepository<WProcessItemDetail, Long>, JpaSpecificationExecutor<WProcessItemDetail>{
}
and the service class is
#Service("processItemDetailsService")
#Transactional
public class WProcessItemDetailsService implements Serializable{
/**
*
*/
private static final long serialVersionUID = 2395733723021028217L;
#Autowired
WProcessItemDetailsRepo detailsRepo;
public WProcessItemDetail save(WProcessItemDetail detail){
return detailsRepo.save(detail);
}
public List<WProcessItemDetail> save(List<WProcessItemDetail> details){
return (List<WProcessItemDetail>) detailsRepo.save(details);
}
}
When I try to run the program, it fails with the following stack trace
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

Here is my EventPublisher
#Component
public class EventPublisher {
#Autowired
private ApplicationEventPublisher applicationEventPublisher;
public void publishEvent(String message, Integer eventId) {
applicationEventPublisher.publishEvent(

}
}
Service:
#Service

#Autowired
EventPublisher eventPublisher;
If #Components (incl #Services) are in are not in the same package (or a sub-package) as the class annotated with #SpringBootApplication then the #SpringBootApplication needs a scanBasePackages, eg
#SpringBootApplication(scanBasePackages = {"basepackage1", "basepackage2"}
The error I get is NoSuchBeanDefinitionException,
I have a web app that I am currently working on to integrate some DB functionality.
My structure is below
domain.mainpackage
+ControllerClass

domain.DAOpackage
+someDAOClass
+someDAOimpl
domain.service
+MainService
+MainServiceImpl
The issue I am having is that Controller when building the app cannot find the bean for the MainServiceClass (see error below)

I have annotated my Implementation class as #Service
#Service
public class MainServiceImpl implements someDAOClass{
#Autowired
private someDAOClass someDAOClass1;
#Transactional
public list<someDAOClass> getSomeDAOClass(){
//return statement here
}
}
Additionally, my DAO class is annotated as #Repository, non-transactional. Yesterday I achieved the desired result with just using a DAO but now I made changes I am not sure why it is not all working together.
I have tried using #ComponentScan on my controller, just in case but that was futile.
As I am using STS(Eclipse), it appears I cannot create a root package and keep controller there as suggested as a solution in another SO post. Therefore, I am looking for other solutions apart from changing architecture in system explorer.
Your service implementation class should implements Service and not DAO
#Service
public class MainServiceImpl implements MainService {
You should define your bean for example:
#Bean
public MainService mainService(){
return new MainServiceImpl ();
}
The error says,
No qualifying bean of type 'domain.service.MainService' available
MainServiceImpl is a someDAOClass, not a MainService. So you should implement MainService.
I am developing a solution to implements several providers in a SmsService. I need a way to inject the strategy class from my Context. The problem is the selection depends on an external property. When I try to deploy this code I get
org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type
Here I show you my code:
Provider Interface
public interface SmsProvider {
public Integer send(String user, String password,List<Sms> list);
}
Context class
#Component
public class ContextProvider {
private #Inject
MessageDAO messageDAO;
private #Inject
SmsProvider strategy;
public Integer send(String user,String password) {
List<Sms> list = extractSmsList();
return strategy.send(user,password, list);
}
public void setStrategy(SmsProvider strategy) {
this.strategy = strategy;
}
Strategy A
#Component("provider1")
public class Provider1 implements SmsProvider {
private #Inject
MessageDAO messageDAO;
public Integer send(String user, String password, List<Sms> list) {
Status serviceErrorStatus = messageDAO.find(Status.class, 400);
...
}
Strategy B
#Component("provider2")
public class Provider2 implements SmsProvider{
private #Inject
MessageDAO messageDAO;
#Override
public Integer send(String user, String password, List<Sms> list) {
Status serviceErrorStatus = messageDAO.find(Status.class, 400);
...
}
Using the strategy.
In this class I get the property and choose the strategy in a switch clause.
#Component
public class SmsServiceImpl implements SmsService{
#Value("${net.mycompany.sms.service.smsProvider}")
private int smsProvider;
private #Inject
MessageDAO messageDAO;
private #Inject
ContextProvider context;
....
public Integer send(String user,String password) {
LOG.debug("Sms provider property setted at: '{}'",smsProvider);
switch (smsProvider) {
case 1:
context.setStrategy(new Provider1());
return context.send(user, password);
case 2:
context.setStrategy(new Provider2());
return context.send(user, password);
}
}
I have also try to delete the #Component in the strategies classes and #Inject in the declaration of smsProvider in Context class and I get a NullPointerException in Dao class and I really need this daos.
I am using Spring 3.2.16-RELEASE and Java 7.0.15
Please a help. Any pointers would be helpful
Thanks in advance

I would take advantage of the FactoryBean interface provided by Spring and encapsulate the creation of SmsProvider in proper place.
As you are using annotation configuration then based on your class definitions, the FactoryBean configuration would look like this:
First: we encapsulate the selection of the strategy based on the injected external property:
#Component
public class SmsProviderFactoryBean implements FactoryBean<SmsProvider>{
#Inject
private ApplicationContext applicationContext;
#Value("${net.mycompany.sms.service.smsProvider}")
private int smsProvider;
#Override
public SmsProvider getObject() throws Exception {
SmsProvider smsProvider = null;
switch (smsProvider) {
case 1:
smsProvider = (SmsProvider) applicationContext.getBean("provider1");
case 2:
smsProvider = (SmsProvider) applicationContext.getBean("provider2");
}
return smsProvider;
}
}
Second: Define the configuration bean which getSmsProvder() method will be used when the 'smsProvider' bean would be injected into other beans:
#Component
public class Configuration {
#Inject
private ApplicationContext applicationContext;
#Bean(name = "smsProvider")
public SmsProvider getSmsProvider() throws Exception {
return applicationContext.getBean(SmsProviderFactoryBean.class)
.getObject();
}
}
Thirdly: Add #Qualifer when you are injecting the 'smsProvider' (this may not be necessary depending on which spring version you are using):
#Component
public class ContextProvider {
#Inject
#Qualifier("smsProvider")
private SmsProvider strategy;
Give it a try.
You can use spring profiles for this.
Annotate each implementation with a profile :
#Component("provider1")
#Profile("provider1")
public class Provider1 implements SmsProvider {...}
#Component("provider2")
#Profile("provider2")
public class Provider2 implements SmsProvider {...}
When you start the application, activate one of the profiles. With spring boot you can do this by setting the property 'spring.profiles.active' on the commandline or in a properties file, for example
spring.profiles.active=profile1
you can name the profiles however you like, I used the same name as the component only for simplicity
annotating the component class with #Profile only works if you are using ComponentScan, if you use Java config, you need to annotate the #Bean method
You can find more about profiles with spring-boot in the spring doc
You can use profiles also without spring-boot, see this tutorial
I have created a sample Spring Boot application that runs perfectly fine when service classes are all in one package , but if a Service class refers to another service class in a different package then I get the BeanCreationException
The Code for the Application is given below
Main.java
#SpringBootApplication
public class Main {
public static void main(String[] args) {
SpringApplication.run(Main.class, args);
}
}
MyRunner
#Component
#ComponentScan(basePackages ="com.springboot.helloworld")
public class MyRunner implements CommandLineRunner {
#Autowired
private GreeterService greeterService;
#Override
public void run(String... args) throws Exception {
System.out.println(greeterService.greetGuest("John Doe"));
}
}
GreeterService and GreeterServiceImpl are in com.springboot.helloworld.Greeter
#Service
public class GreeterServiceImpl implements GreeterService {
#Autowired
Sample service;
#Override
public String greetGuest(String greeter) {
if (greeter == null) {
return "Looged in as Guest";
}
return "Hello " + greeter + " How are you?";
}
}
Sample and SampleImpl are in different Package com.springboot.helloworld.Sampler
Error Recieved is

You have to use the #Component annotation something like below:
#ComponentScan({"com.springboot.helloworld","service"})
Your application is clearly expecting a command line argument and you're not supplying any.
I had this issue after switching to spring 5. The problem was that an annotation processor was being run at build time to generate some helper classes, a side effect of this was that a file, spring.properties was generated. This got deployed to META-INF. When spring 5 scans for components, it checks to see if this file exists (as a resource loaded by the class loader), if it exists then it only considers the classes listed in the file when looking for components. In my case the annotation processor that generated the file wasn't looking for components, so the component classes weren't in the file. The fix was to delete the file. Without the file, then the component scanning works as expected.
I'm trying to run simple mailsender service:
#Service
public class MailService {
#Autowired
private MailSender mailSender;
#Autowired
private SimpleMailMessage templateMessage;
#Autowired
private AuthenticationService authenticationService;
public void sendMessage(SaveSurveyDTO saveSurvey) {
title += "title2";
templateMessage.setSubject(title);
// templateMessage.setTo(email.toString());
templateMessage.setTo("my#mail.com");
mailSender.send(templateMessage);
}
}
#Configuration
public class MailConfig {
#Bean
public JavaMailSenderImpl mailSender() {
JavaMailSenderImpl sender = new JavaMailSenderImpl();
Properties props = new Properties();
props.put("mail.smtp.auth", true);
props.put("mail.debug", "true");
props.put("mail.smtp.host", "adres");
props.put("mail.smtp.port", "25");
props.put("mail.smtp.auth.mechanisms", "NTLM");
props.put("mail.smtp.auth.ntlm.domain", "DOMAIN");
sender.setHost("host");
sender.setPort(25);
sender.setJavaMailProperties(props);
sender.setUsername("username");
sender.setPassword("pass");
return sender;
}
}
When I'm trying to run this, I recieve the following error:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.mail.SimpleMailMessage] 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)}
The main issue is the fact you are having field in your service of the type SimpleMailMessage which you have annotated with #Autowired. However there is no such bean in your #Configuration class.
Either add that bean definition to your configuration (which I wouldn't recommend) or simply create the SimpleMailMessage inside your method.
public void sendMessage(SaveSurveyDTO saveSurvey) {
SimpleMailMessage message = new SimpleMailMessage();
title += "title2";
message.setSubject(title);
// templateMessage.setTo(email.toString());
message.setTo("my#mail.com");
mailSender.send(message);
}
Pro Tip
You are using Spring Boot then use it... Remove your#Configuration class and just put the configuration in application.properties. Spring Boot already has mail support (as of Spring Boot 1.2 that is!).
spring.mail.host=adres
spring.mail.port=25
spring.mail.username=username
spring.mail.password=password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.auth.mechanisms=NTLM
spring.mail.properties.mail.smtp.auth.ntlm.domain=DOMAIN
spring.mail.properties.mail.debug=true
The problem you are getting is that Spring cannot inject an instance of SimpleMailMessage:
#Autowired
private SimpleMailMessage templateMessage;
This is completely normal and you should not construct a SimpleMailMessage this way, it is not a Spring Bean. Rather, use the default constructor:
SimpleMailMessage templateMessage = new SimpleMailMessage();
and set the properties from, to, etc. according to your needs.
Please add the Qualifier like this
#Autowired
#Qualifier("mailSender")
private MailSender mailSender;
