Consider defining a bean of type 'package' in your configuration [Spring-Boot]

I am getting the following error:

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of method setApplicant in webService.controller.RequestController required a bean of type 'com.service.applicant.Applicant' that could not be found.


Action:

Consider defining a bean of type 'com.service.applicant.Applicant' in your configuration.

I have never seen this error before but it's odd that the @Autowire is not working. Here is the project structure:

Applicant Interface

public interface Applicant {
    
    TApplicant findBySSN(String ssn) throws ServletException;
    
    void deleteByssn(String ssn) throws ServletException;
    
    void createApplicant(TApplicant tApplicant) throws ServletException;
    
    void updateApplicant(TApplicant tApplicant) throws ServletException;
    
    List<TApplicant> getAllApplicants() throws ServletException;
}

ApplicantImpl

@Service
@Transactional
public class ApplicantImpl implements Applicant {

private static Log log = LogFactory.getLog(ApplicantImpl.class);
    
    private TApplicantRepository applicantRepo;

@Override
    public List<TApplicant> getAllApplicants() throws ServletException {
        
        List<TApplicant> applicantList = applicantRepo.findAll();
        
        return applicantList;
    }
}

Now I should be able to just Autowire Applicant and be able to access, however in this case it is not working when I call it in my @RestController:

@RestController
public class RequestController extends LoggingAware {
    
    private Applicant applicant;
    
    @Autowired
    public void setApplicant(Applicant applicant){
        this.applicant = applicant;
    }
    
    @RequestMapping(value="/", method = RequestMethod.GET)
    public String helloWorld() {
        
        try {
            List<TApplicant> applicantList = applicant.getAllApplicants();
            
            for (TApplicant tApplicant : applicantList){
                System.out.println("Name: "+tApplicant.getIndivName()+" SSN "+tApplicant.getIndSsn());
            }
            
            return "home";
        }
        catch (ServletException e) {
            e.printStackTrace();
        }
        
        return "error";
    }
    
}

------------------------UPDATE 1-----------------------

I added

@SpringBootApplication
@ComponentScan("module-service")
public class WebServiceApplication extends SpringBootServletInitializer {

    @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(WebServiceApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(WebServiceApplication.class, args);
    }

}

and the error went away but nothing happened. However when I commented out everything dealing with Applicant in the RestController prior to adding @ComponentScan() I was able to return a string the UI, thus meaning my RestController was working, now it is being skipped. I got an ugly Whitelabel Error Page now.

---------------------UPDATE 2------------------------------

I added the base package of the bean it was complaining about. Error reads:

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of method setApplicantRepo in com.service.applicant.ApplicantImpl required a bean of type 'com.delivery.service.request.repository.TApplicantRepository' that could not be found.


Action:

Consider defining a bean of type 'com.delivery.request.request.repository.TApplicantRepository' in your configuration.

I added @ComponentScan

@SpringBootApplication
@ComponentScan({"com.delivery.service","com.delivery.request"})
public class WebServiceApplication extends SpringBootServletInitializer {

    @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(WebServiceApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(WebServiceApplication.class, args);
    }

}

----------------------------Update 3----------------------

adding:

@SpringBootApplication
@ComponentScan("com")
public class WebServiceApplication extends SpringBootServletInitializer {

still is complaining about my ApplicantImpl class which @Autowires my repo TApplicantRepository into it.

It was working for me after replacing with jakarta.persistence.Entity instead of javax.persistence and also added @ComponentScan({"com.myapp.service","com.myapp.repo"}) then solved my problem

It might be because the project has been broken down into different modules:

@SpringBootApplication
@ComponentScan({"com.delivery.request"})
@EntityScan("com.delivery.domain")
@EnableJpaRepositories("com.delivery.repository")
public class WebServiceApplication extends SpringBootServletInitializer {

Try to remove

@ComponentScan({"com.delivery.service","com.delivery.request"})

File WebServiceApplication.java at folder where the most outter of all files/packages.

@SpringBootApplication
public class WebServiceApplication extends SpringBootServletInitializer {

    @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(WebServiceApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(WebServiceApplication.class, args);
    }

}

i had the "Action: Consider defining a bean of type 'blabla.blabla.blabla.repository' in your configuration." error and this is how i fixed it;

I was work with a MongoDB. that so, my "EmployeeRepo.java interface" had to contains as like this;

**public interface EmployeeRepo extends MongoRepository<Employee, Long> **

Firstly, the area with the MongoRepository part was like this "JPARepository". Then i changed with the MongoRepository. And the problem fixed

Use @Component for the Class where the Bean is not found. And Use

@ComponentScan("<Use_The_Root_Directory_Of_Main_Class>")

. This can happen when the Components are spread over many directories.

@Configuration
@SpringBootApplication
@ComponentScan({"com.example.demo"})
public class Application {
}

This can also happen if you have two beans with the same name.

For example if you have factory method monkey creating Monkey and you mistakenly name another factory method (creating Car) also monkey.

Problematic code:

    @Bean
    public Car monkey() {
        return new Car();
    }

Should be:

    @Bean
    public Car car() {
        return new Car();
    }

Reference:

By default, the bean name will be the same as the method name...

Spring doc 1

Autowiring by property name. Spring looks for a bean with the same name as the property that needs to be autowired. For example, if a bean definition is set to autowire by name and it contains a master property (that is, it has a setMaster(..) method), Spring looks for a bean definition named master and uses it to set the property.

I also received a similar error:

Consider defining a bean of type 'A_REPOSITORY_INTERFACE' in your configuration.

Then, according to Akashe's solution, I added @EnableJpaRepositories to my main class. After that, I received the following error instead:

Consider defining a bean of type 'entityManagerFactory' in your configuration.

Next, I went through all the responses here, googled a lot and read a lot of other resources, which didn't worked out.

Finally, I was lucky to have found the solution on a blog/website (javatute.com). I just followed its examples.

Like suggested by many here, I added @ComponentScan("YOUR_BASE_PACKAGE.*") and @EntityScan("YOUR_BASE_PACKAGE.*") to my main app class, followed by adding a config package and creating a JpaConfig class like:

package YOUR_BASE_PACKAGE.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@Configuration
@EnableJpaRepositories(basePackages = "YOUR_BASE_PACKAGE")
public class JpaConfig {

}

The blog I followed:

Consider defining a bean of type in your configuration

which lead me to:

Error creating bean with name entityManagerFactory defined in class path resource : Invocation of init method failed

and finally to:

@Service should be imported from org.springframework.stereotype.Service

you might be importing it from org.jvnet.hk2.annotations.Service

In CrudRepository, check if the Entity class @Id using import javax.persistence.Id;, not import org.springframework.data.annotation.Id;

I had the same problem, i was get this error for redis repository like this:

@Repository
public interface AppTokenRepository extends CrudRepository<AppToken, String> {
}


@RedisHash("APP_TOKEN")
public class AppToken implements Serializable {
    private String id;
    private String accessToken;
}

I solved my issue by adding @EnableRedisRepositories over spring boot application class.

Had the same error, transpired it was an issue with the application properties with incorrect username, password and driver and completely unrelated to Bean.

For me, it was because of using @Value in class that use lombok @RequiredArgsConstructor annotation. Just changed it to constructor injection.

There is a chance...
You might be missing @Service, @Repository or @Component annotation on your respective implementation classes.

In my case, this problem was caused by an errant spring.autoconfigure.exclude property value. I had this property because my Spring Boot project initially didn't connect to a database, but then I added my first JpaRepository class and tried to declare an instance of it with the @Autowired annotation in a @RestController class.

The line in application.properties that caused the problem:

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

Once I deleted or commented out that line, my Spring Boot service ran just fine.

In my case, I have just added @Component annotations to some classes (to make sure every Classes have configuration).

@Component, @Service or @Repository are almost familiar. Baeldung link reference

I had a similar issue, exact same error message. But my error only happened when I tried to install and run on my local docker.

Turns out the issue was profile dependant.

I had two classes that implemented the interface, one with a production Profile @Profile("prod") and the second with the "Test Environment" profiles. @Profile("!local & !prod")

However, there was no active profile for when I tried to run locally (on Docker).

I created a 3rd class that implemented the interface for a local profile @Profile("local") and this fixed my issue

I had the same issue while using MongoDB due to incorrect basePackages name of the @Repository class

If you are using Eclipse and tried all possibilities and you still have errors, then try to update the project using Maven. You can to this like this: Right click on your project-> Maven -> Update Project.

It helped me to solve my errors. Sometimes Eclipse shows this error if a project is not updated with all repos which you declared in the pom file.

This error message also pops up when you fail to annotate the Entity classes associated with your bean with the @Entity Annotation.

My ComponentScan worked fine but this popped up for the @repository interface:

@Repository
public interface ExpenseReportAuditRepository extends 
     PagingAndSortingRepository<ExpenseReportAudit, Integer> {

because I failed to add the @Entity annotation to ExpenseReportAudit

@Entity // <--- Adding this fixed the issue.
public class ExpenseReportAudit {
  .....

I think you can make it simplified by annotating your repository with @Repository, then it will be enabled automatically by Spring Framework.

In my case, our project has a Configuration class, so I just added mine like this

@Configuration
public class DependencyConfiguration {

    @Bean
    public ActivityService activityService(
            @Value("${send.money.ms.activity.url}") final String activityHistoryUrl,
            final HttpRestService httpRestService
    ) {
        return new ActivityServiceImpl(activityHistoryUrl, httpRestService);
    }

.......................

Then the microservice started alright.

PS: I encountered this issue even though the library I need is imported properly and could be seen on External Libraries imported.

For me - using Spring Boot with MongoDB, the following was the Problem:

In my POM.xml I had:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-starter-data-mongodb</artifactId>
</dependency>

but I needed the following:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
    </dependency>

(Short: Add "spring-boot-..." instead of only "spring-...")

To fix errors like:

Consider defining a bean of type 'package' in your configuration
Not a managed type

It happened to me that the LocalContainerEntityManagerFactoryBean class did not have the setPackagesToScan method. Then I proceeded to use the @EntityScan annotation which doesn't work correctly.

Later I could find the method setPackagesToScan() but in another module, so the problem came from the dependency which did not have this method because it was an old version.

This method can be found in the spring-data-jpa or spring-orm dependency of updated versions:

From:

implementation("org.springframework", "spring-orm", "2.5.1")

To:

implementation("org.springframework", "spring-orm", "5.2.9.RELEASE")

Or to:

implementation("org.springframework.data", "spring-data-jpa", "2.3.4.RELEASE")

In addition, it was not necessary to add other annotations other than that of @SprintBootApplication.

@SpringBootApplication
open class MoebiusApplication : SpringBootServletInitializer()

@Bean
open fun entityManagerFactory() : LocalContainerEntityManagerFactoryBean {
    val em = LocalContainerEntityManagerFactoryBean()
    em.dataSource = dataSource()
    em.setPackagesToScan("app.mobius.domain.entity")
    ... 
}

Important:

For anybody who was brought here by googling the generic bean error message, but who is actually trying to add a feign client to their Spring Boot application via the @FeignClient annotation on your client interface, none of the above solutions will work for you.

To fix the problem, you need to add the @EnableFeignClients annotation to your Application class, like so:

@SpringBootApplication
// ... (other pre-existing annotations) ...
@EnableFeignClients // <------- THE IMPORTANT ONE
public class Application {

Side note: adding a @ComponentScan(...) beneath @SpringBootApplication is redundant, and your IDE should flag it as such (IntelliJ IDEA does, at least).

Moving the Springbootapplication(application.java) file to another package resolved the issue for me. Keep it separate from the controllers and repositories.

reminder that spring doesn't scan the world , it uses targeted scanning wich means everything under the package where springbootapplication is stored. therefore this error "Consider defining a bean of type 'package' in your configuration [Spring-Boot]" may appear because you have services interfaces in a different springbootapplication package .

Try configuring the project structure as given below:

Put all the repo, service, packages in the child package of the main package:

package com.leisure.moviemax;  //Parent package
        
@SpringBootApplication
@PropertySource(value={"classpath:conf.properties"})
    
public class MoviemaxApplication implements CommandLineRunner {
        
package com.leisure.moviemax.repo; //child package

@Repository
public interface UsrRepository extends JpaRepository<UserEntity,String> {
