Injection of autowired dependencies failed with Spring MVC

I'm trying to make a simple application with SPing but I keep getting this error and I dont understand why.
I have tried everything, even wre-wrote the whole app. Dont even know what the problem could be.
This is the error I get:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'blogPostController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.vst.blog.service.BlogService com.vst.blog.controller.BlogPostController.blogServiceImpl; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.vst.blog.service.BlogService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

This is the class interface.
package com.vst.blog.service;
import java.sql.SQLException;
import java.util.List;
import org.springframework.stereotype.Repository;
import com.vst.blog.model.BlogPost;
public interface BlogService {
public void insertBlogPost(BlogPost post) throws SQLException;
public BlogPost selectBlogPostById(int id);
public List<BlogPost> selectBlogPostS();
public void deleteBlogPost(int id) throws SQLException;
public void updateBlogPost(BlogPost post) throws SQLException;
}
And here is the implementation of it:
package com.vst.blog.service;
import java.sql.SQLException;
import java.util.List;
import javax.transaction.Transactional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

public class BlogServiceImpl implements BlogService {
#Autowired
private BlogPostDao postDao;
public BlogServiceImpl () {
//postDao = new BlogPostDaoImpl();
}
public void insertBlogPost(BlogPost post) throws SQLException {
postDao.insertBlogPost(post);
}
public BlogPost selectBlogPostById(int id) {
return postDao.selectBlogPostById(id);
}
public List<BlogPost> selectBlogPostS() {

}
public void deleteBlogPost(int id) throws SQLException {
postDao.deleteBlogPost(id);
}
public void updateBlogPost(BlogPost post) throws SQLException{
postDao.updateBlogPost(post);
}
}
This is DaoImpl
package com.vst.blog.dao;
import java.util.List;
import javax.transaction.Transactional;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import com.vst.blog.model.BlogPost;
#Service
#Transactional
public class BlogPostDaoImpl implements BlogPostDao {
public BlogPostDaoImpl () {}
#Autowired
private SessionFactory sessionFactory;
public void insertBlogPost(BlogPost post) {
sessionFactory.getCurrentSession().saveOrUpdate(post);
}
public BlogPost selectBlogPostById(int id) {
return (BlogPost) sessionFactory.getCurrentSession().get(
BlogPost.class, id);
}
#SuppressWarnings("unchecked")
public List<BlogPost> selectBlogPostS() {
return sessionFactory.getCurrentSession().createQuery("from blog")
.list();
}
public void deleteBlogPost(int id) {
BlogPost post = (BlogPost) sessionFactory.getCurrentSession().load(
BlogPost.class, id);
if (null != post) {
this.sessionFactory.getCurrentSession().delete(post);
}
}
public BlogPost updateBlogPost(BlogPost post) {
sessionFactory.getCurrentSession().update(post);
return post;
}
}
And here is its interface
package com.vst.blog.dao;
import java.sql.SQLException;
import java.util.List;
import org.springframework.stereotype.Repository;
import com.vst.blog.model.*;
#Repository
public interface BlogPostDao {

Here some tips to detect this rare errors related to:
Injection of autowired dependencies failed
Use just one scan:
<context:component-scan base-package="com.VST" />
Instead
<context:component-scan base-package="com.VST.blog.service" />
<context:component-scan base-package="com.VST.blog.controller" />
<context:component-scan base-package="com.VST.blog.dao" />
validate that all your spring beans are in this package or child of it:
com.VST
create an empty class with some method inside of your base package com.vst and try to autowire it. This could reveal that not even a simple empty autowire works!!
Remove "impl" from autowired clases. In your example, change this
BlogService blogServiceImpl;
to
BlogService blogService;
in your BlogPostControllerImpl
Another tips
don't use uppercase in packages
use spring boot :D

Spring - trouble with injecting validator bean

i couldn't find solution for my problem anywhere.
I'm trying to make validation working in spring web flow form. I need to
set validator in configuration, however it's located in another config file
and it seems spring can't find proper bean. How can I achieve successful injection here?
As far as I know, Autowiring should inject bean into validator reference.
Maybe it has something to do with order of loading configuration classes?
WebConfig.java:
#Configuration
#Import(godziszewski.patryk.ElectronicsStore.config.FlowConfiguration.class)
#EnableWebMvc
#ComponentScan(basePackages = "godziszewski.patryk")
public class WebConfig extends WebMvcConfigurerAdapter {
....
#Bean
public LocalValidatorFactoryBean validator()
{
LocalValidatorFactoryBean lv = new LocalValidatorFactoryBean();
lv.setValidationMessageSource(messageSource());
return lv;
}
}
FlowConfiguration.java:
#Configuration
public class FlowConfiguration extends AbstractFlowConfiguration {
#Autowired
Validator validator;
....
#Bean
public FlowBuilderServices flowBuilderServices()
{
FlowBuilderServices fbs = new FlowBuilderServices();
fbs.setValidator(validator);
return fbs;
}
}
The error i'm getting:
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'flowConfiguration':
Unsatisfied dependency expressed through field 'validator':
No qualifying bean of type [org.springframework.validation.Validator] found for dependency [org.springframework.validation.Validator]:
expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)};
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:

expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
Im using spring 4.3.2.RELEASE
However, when I delete Validator dependency from FlowAdapter.class I get error :
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flowBuilderServices' defined in class path resource [godziszewski/patryk/ElectronicsStore/config/FlowConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: The ViewFactoryCreator is required

public FlowExecutor flowExecutor() {
return getFlowExecutorBuilder(flowRegistry()).build();
}
#Bean
public FlowHandlerMapping flowHandlerMapping()
{
System.out.println("flowconfig");
FlowHandlerMapping fh = new FlowHandlerMapping();
fh.setFlowRegistry(flowRegistry());
return fh;
}
#Bean
public FlowHandlerAdapter flowHandlerAdapter()
{
FlowHandlerAdapter fh = new FlowHandlerAdapter();
fh.setFlowExecutor(flowExecutor());
return fh;
}
#Bean
public FlowBuilderServices flowBuilderServices()
{
FlowBuilderServices fbs = new FlowBuilderServices();
//fbs.setValidator(validator);
return fbs;
}
}
If i delete .setFlowBuilderServices(flowBuilderServices()) method, everything works fine
EDIT: I managed to get this working by deleting #Configuration annotation form flow config class, now it looks like this:
//#Configuration
public class FlowConfiguration extends AbstractFlowConfiguration {
#Autowired
Validator validator;
...
#Bean
public FlowBuilderServices flowBuilderServices()
{
System.out.println(validator.toString());
FlowBuilderServices fbs = new FlowBuilderServices();
fbs.setValidator(validator);
return fbs;
}
And now I can use injected LocalValidatorBean in this class.

I interpret that eventually you need a FlowBuilderServices which has a reference to Validator bean.
This can be achieved by using the Autowired tag inside FlowBuilderServices
public class FlowBuilderServices{
#Autowired
Validator validator
...
}
And then in FlowConfiguration you just need to define the bean
#Bean
public class FlowBuilderServices flowBuilderServices()
{
FlowBuilderServices fbs = new FlowBuilderServices();
return fbs;
}

Constructor injection and arrays with Spring

I would like to understand whether there is a clean way to use constructor injection with arrays in spring-boot (1.3.5.RELEASE).
I've created this simple app that better explains my question:
package com.stackoverflow;
import java.util.Arrays;
import java.util.stream.IntStream;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;
#SpringBootApplication
public class Application {
private static class Car { }
#Bean
public Car[] cars() {
return IntStream.range(0, 10).mapToObj(i -> new Car()).toArray(Car[]::new);
}
#Component
private static class Road implements CommandLineRunner {
private final Car[] cars;
#Autowired
public Road(Car[] cars) {
this.cars = cars;
}
// #Resource
// private Car[] cars;
#Override
public void run(String... args) throws Exception {
System.out.println(Arrays.toString(cars));
}
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
I understand that #Autowired works by type, so the reason why the previous application does not work is because when the Car[] has to be injected, Spring first tries to find all Car beans but, since there is no Car bean, the following exception is thrown:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'application.Road' defined in file [/spring-array-injection/target/classes/com/stackoverflow/Application$Road.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [com.stackoverflow.Application$Car[]]: No qualifying bean of type [com.stackoverflow.Application$Car] found for dependency [array of com.stackoverflow.Application$Car]: expected at least 1 bean which qualifies as autowire candidate for this dependency.

I also understand that if I replace the constructor injection with field injection + #Resource everything works because the array is injected by name instead of type.
So, am I missing something or is it a real spring limitation (i.e. it is currently not possible to use constructor injection with arrays/lists of object in spring)?
UPDATE 1
Wow, I thought this question had a shorter life but the case is not solved yet. I will post the two (ugly) workarounds I've tested so far:
A wrapper around the array is injected instead of the plain array:
package com.stackoverflow.workaround.arrayholder;
import java.util.Arrays;
import java.util.stream.IntStream;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;
#SpringBootApplication
public class Application {
private static class ArrayHolder<T> {
private final T array;
public ArrayHolder(T array) {
this.array = array;
}
public T getArray() {
return array;
}
}
private static class Car { }
#Bean
public ArrayHolder<Car[]> cars() {
return new ArrayHolder<>(IntStream.range(0, 10).mapToObj(i -> new Car()).toArray(Car[]::new));
}
#Component
private static class Road implements CommandLineRunner {
private final Car[] cars;
#Autowired
public Road(ArrayHolder<Car[]> cars) {
this.cars = cars.getArray();
}
#Override
public void run(String... args) throws Exception {
System.out.println(Arrays.toString(cars));
}
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
The beans are dynamically created and registered using the BeanFactoryPostProcessor:
package com.stackoverflow.workaround.dynamicregistration;
import java.util.Arrays;
import java.util.concurrent.atomic.AtomicInteger;
import java.util.stream.IntStream;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.BeanFactoryPostProcessor;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Component;
#SpringBootApplication
public class Application implements BeanFactoryPostProcessor {
private static class Car { }
#Override
public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
AtomicInteger atomicInteger = new AtomicInteger();
IntStream.range(0, 10)
.mapToObj(i -> new Car())
.forEach(car -> beanFactory.registerSingleton(String.valueOf(atomicInteger.getAndIncrement()), car));
}
#Component
private static class Road implements CommandLineRunner {
private final Car[] cars;
#Autowired
public Road(Car[] cars) {
this.cars = cars;
}
#Override
public void run(String... args) throws Exception {
System.out.println(Arrays.toString(cars));
}
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Update 2
It turns out that constructor injection of arrays, collections and maps will be possible starting from Spring 4.3 (see issue).

As stated in the docs:
6.9.4 Fine-tuning annotation-based autowiring with qualifiers
If you intend to express annotation-driven injection by name, do not primarily use #Autowired, even if is technically capable of referring to a bean name through #Qualifier values. Instead, use the JSR-250 #Resource annotation, which is semantically defined to identify a specific target component by its unique name, with the declared type being irrelevant for the matching process.
As a specific consequence of this semantic difference, beans that are themselves defined as a collection or map type cannot be injected through #Autowired, because type matching is not properly applicable to them. Use #Resource for such beans, referring to the specific collection or map bean by unique name.
#Autowired applies to fields, constructors, and multi-argument methods, allowing for narrowing through qualifier annotations at the parameter level. By contrast, #Resource is supported only for fields and bean property setter methods with a single argument. As a consequence, stick with qualifiers if your injection target is a constructor or a multi-argument method.
And arrays are treated the same way as collections:
6.4.5 Autowiring collaborators
With byType or constructor autowiring mode, you can wire arrays and typed-collections. In such cases all autowire candidates within the container that match the expected type are provided to satisfy the dependency. You can autowire strongly-typed Maps if the expected key type is String. An autowired Maps values will consist of all bean instances that match the expected type, and the Maps keys will contain the corresponding bean names.
6.9.2 #Autowired
It is also possible to provide all beans of a particular type from the ApplicationContext by adding the annotation to a field or method that expects an array of that type: [...]
The same applies for typed collections: [...]
Even typed Maps can be autowired as long as the expected key type is String. The Map values will contain all beans of the expected type, and the keys will contain the corresponding bean names: [...]

I try to query a record from mongo collections use org.springframework.data.mongodb.core.MongoOperations. I define a method like this "List find(List industries, Pageable pageable)" in CompanyTemplRepoImpl class. The run error messages show as below. When I change the method name to "findByIndustry", The error messages is gone, but I always get a list "[]" as the result.
I have already defined a method named "findByIndustry" in "public interface CompanyRepo extends MongoRepository, CompanyTemplRepo".

The PropertyMatches.forField used by org.springframework.data.mapping.PropertyReferenceException.detectPotentialMatches on spring data, uses two methods that were added on version 4.1.7 of spring-beans. Make sure you are using 4.1.7 or above

Also got this problem from the wrong version of org.springframwork.data.spring-data-mongodb. I went from 1.8.4 to 1.9.3 to get rid of the problem.

You should mark your ExporterServiceImpl with #Service, by the docs
The Resource annotation marks a resource that is needed by the
application.
and
If the annotation is applied to the component class, the annotation
declares a resource that the application will look up at runtime.
so when used on a class-level it doesn't specify the class to be a Spring bean (hence your error), rather just defers the look-up of a target resource to runtime
UPDATE with respect to the comment
This is surely the issue with the code you've posted in the question. For what concerns not working after the changes, wouldn't know, but, will give you some pointers that are at least confusing.
You can consider to use #Autowire, you might check out the #Resource vs #Autowired, in short #Resource is not suppose to inject a dependency by type, but Spring enables this as a fallback. I would still advise to give #Autowired a try.
I also notice that you don't have the <mvc:annotation-driven/> in your mvc-dispatcher-servlet.xml, this is not causing your issue directly, but the handlers for controller mappings won't be created without it.
Finally, a suspicious, but not an important change is, you access your beans with a fully qualified name, e.g. services.ExporterService, and you initialize it to null. This should also not pose any problem, but its unconventional, you should simply add an import declaration and omit setting to null.

Try using #Autowired and enabling .
But besides that, just so you know by Spring's best practice, there are 3 layers:
#Controller, #Service, #Repository.
#Controller is obviously the controller,
#Repository would be your DAO classes, in this instance you name your class "Service", but in reality you're using it as a DAO class, so it should actually get a #Repository annotation.
#Service layer is where you'll do your conversions, business logic, caching, etc.
