I'm going through the JPA starter tutorial for spring boot am struggling.
I know the question has been asked sometimes here ('Field required a bean of type that could not be found.' error spring restful API using mongodb)
But those problems are a bit different from what I have.
Structure
java
|
helloWorld
|
web/ -- HelloWorldController
Application
Customer
CustomerRepository
ServletInitializer
As you can see all my packages related to JPA are on the same level as my Application file . According to the tutorial (https://spring.io/guides/gs/accessing-data-jpa/) this should work
My Application class
package helloWorld;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Autowired
CustomerRepository customerRepository;
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
CustomerRepository
package helloWorld;
import org.springframework.data.repository.CrudRepository;
import java.util.List;
public interface CustomerRepository extends CrudRepository<Customer, Long> {
List<Customer> findByLastName(String lastName);
}
When trying to use #Autowired I receive
***************************
APPLICATION FAILED TO START
***************************
Description:
Field customerRepository in helloWorld.Application required a bean of type 'helloWorld.CustomerRepository' that could not be found.
Action:
Consider defining a bean of type 'helloWorld.CustomerRepository' in your configuration.
Also, adding scanBasePackages={"helloWorld"}) to #SpringBootApplication does not help and from what I read it should also not be needed.

You are excluding the autoconfiguration of JPA repositories. Remove the line from application.properties to let Spring make CustomerRepository a bean and configure it.
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
In my case, I just forgot to add #Component to Impl class of interface!
These errors may be due to absence of one or more stereotype annotations.
I changed this Class Level Annotation from my Application Class.
From:
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
To:
#SpringBootApplication
Try Adding the #ComponentScan("package.path.to.your.repository") annotation above Application class.
- Just make sure your repository is in the the same package path that is written in #ComponentScan
#SpringBootApplication
#ComponentScan("helloworld")
public class Application extends SpringBootServletInitializer {
//your stuff
}
I had the same issue and everything was good except adding the below dependecies.
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>2.4.2</version>
And, It worked for me
you need to add #Repository in repository

I'm new to spring boot and trying to learn how to implement graphql. #GetMapping and #PostMapping work as normal but when I try to use #QueryMapping or #SchemaMapping, following the Spring documentation I get the whitelabel error page. Playing around I'm able to guess that it's not recognizing these two as mapping. I've checked my dependencies but I'll include them below in case, I've verified the project structure, and I've also tried changing from #Controller to #RestController to no avail.
Controller file
package com.example.GraphQLBooks.controller;
import com.example.GraphQLBooks.model.Book;
import com.example.GraphQLBooks.repository.BookRepository;
import org.springframework.graphql.data.method.annotation.QueryMapping;
import org.springframework.graphql.data.method.annotation.SchemaMapping;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
#RestController
public class BookController {
private final BookRepository bookRepository;
public BookController(BookRepository bookRepository) {
this.bookRepository = bookRepository;
}
//This works with #RestController but breaks with #Controller
#GetMapping("/test")
public String controllerTest(){
return "Hello";
}
//#SchemaMapping(typeName = "Query",value = "allBooks")
#QueryMapping
public List<Book> findAll() {
return bookRepository.findAll();
}
}

I tested the repositories using #GetMapping and they output as expected and when I got to my "/test" mapping it outputs Hello as expected. Any insight and tips are appreciated, and let me know if more info is needed.
Figured it out. My schema had a typo had schema.graphql instead of schema.graphqls and it should be localhost:8080/graphiql not localhost:8080/graphql dumb mistakes I know. And you can't use #RestController with graphql has to be #Controller which makes sense because we're not using a Rest Api.
Had similar issue. The problem was graphqls file wasn't placed in the right folder.
Spring boot graphQL looks for the graphqls file in the following directory by default: ~/src/main/resources/graphql/schema.graphqls
I'm going through this online course about Spring MVC.
During the course the instructor is adding a simple controller, and a simple jsp page.
In addition the application class is extending SpringBootServletInitializer.
my index.html file is found in src/main/webapp and my jsp file is found in src/main/webapp/WEB-INF/jsp
I've also added spring.mvc.view.prefix/suffix accordingly.
for some reason when i get to this point at the course, extending the SpringBootServletInitializer is causing whitelabel error to my main view (index.html) but the path to jsp file is working just fine.
I've tried some suggestions as changing #Controller to #RestController or removing the SpringBootServletInitializer but it didn't work (removing the SpringBootServletInitializer caused 404 when looking for the jsp page).

*Ehcache3 not working with spring boot - I tried out with approach given below. Spring boot never caches the value mentioned in the component.It is getting called n - no of times no matter the cache is enable or not. In the logs it shows cache is added to cache manager but thats not the case here

<ehcache:config>
<ehcache:cache-template name="myDefaultTemplate">

Application.java which starts spring boot app
#SpringBootApplication
#ComponentScan(basePackages = {"com.service"})
#EnableCaching
public class TestApplication {
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
}
Component class for caching -
#Component
public class CustomerService {
#Cacheable(cacheNames = "customer",key="#id")
public Customer getCustomer(final Long id){
System.out.println("Returning customer information for customer id
{}
"+id);
Customer customer = new Customer();
customer.setCustomerId(id);
customer.setFirstName("Test");
customer.setEmail("contact-us#test.com");
return customer;
}
}
I tried with couple of approaches by adding component scan in the application
but didn't worked out.
Spring boot starts and it shows cache has been added to cache manager.
I got it working by changing from #Component to #Service. I don't understand why caching is not working under component and works in service layer
If you want to add Caching annotation at the Repository layer then just remove #Repository Annotation, If you want to add Caching at Service Layer then use #Service Annotation instead of #Component Annotation.
I have some project trying to build a microservices architecture. Some of the projects are used producing jar files (I refer these projects as "library projects".) for the callable microservices. One of these microservices are responsible for user/customer registration and lookup. All the data is persisted in a Cassandra cluster. One of the library projects are responsible for providing various Cassandra based services/value objects, etc...
In the microservice pom file, I include the jar produced by the library
project. It compiles, but when I start the customer service the classes from that jar are not found.

UPDATE (SOME EXTRA INFO ADDED):
Here is the main class containing the component scan.
#SpringBootApplication
#EnableEurekaClient
#ComponentScan(basePackages = {"com.besztercekk.tao.customer", "com.besztercekk.tao.cassandra"})
public class CustomerBackendApplication {
public static void main(String[] args) {
SpringApplication.run(CustomerBackendApplication.class, args);
}
}
Here is the repository class:
package com.besztercekk.tao.cassandra.repository;
import java.util.UUID;
import org.springframework.data.cassandra.repository.ReactiveCassandraRepository;
import org.springframework.stereotype.Component;
import com.besztercekk.tao.cassandra.model.User;
import reactor.core.publisher.Mono;
/**
* This interface provides reactive {#link User} services.
*/
public interface ReactiveUserRepository extends ReactiveCassandraRepository<User, UUID> {
Mono<User> findByUsername(String username);
Mono<User> findByEmail(String email);
}
Also tried to add #Component and #Repository annotations to this interface, just to see its effect. :-)
My other idea was add the bean programatically to the context after restart. But this is just an interface, so not sure if it works out at all.
The third idea was wrap this interface into a service class and that is easy to add programatically.
But I really want it to be added automatically, without writing code.
Try adding the following annotation to any of the #Configuration classes:
#EnableReactiveCassandraRepositories
#Configuration
class MyConfiguration() {
//code
}
The above code enables spring to automatically scan and create the default implementation bean for your interface ReactiveUserRepository .
Also annotate the interface like :
#Repository
public interface ReactiveUserRepository extends ReactiveCassandraRepository<User, UUID> {
Mono<User> findByUsername(String username);
Mono<User> findByEmail(String email);
}
For more details read :
https://dzone.com/articles/reactive-streams-with-spring-data-cassandra
Also, if you would like more details on the annotations read a similar post :
how annotation #Repository in java spring work?
I am trying to configure the spring boot with jersey but it seems jersey annotations are not working with spring boot.
can you please help me out.
I have tried #RestController instead of #Component and #RequestMapping instead of #Path in service class.

Spring Boot Jersey Example July 14, 2017 by Lokesh Gupta. This seems to be the part you're missing.
Jersey Configuration
1: Now we have a JAX-RS resource and we want to access it from spring boot application which include Jersey dependency. Let’s register this resource as Jersey resource.
package com.howtodoinjava.jerseydemo;
import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.stereotype.Component;
#Component
public class JerseyConfig extends ResourceConfig
{
public JerseyConfig()
{
register(UserResource.class);
}
}
Look at the #Component annotation. It enables this class to be registered while spring boot auto scans the java classes in source folder.
2: ResourceConfig provides advanced capabilities to simplify registration of JAX-RS components.
3: Extend spring boot application with SpringBootServletInitializer.
package com.howtodoinjava.jerseydemo;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
#SpringBootApplication
public class JerseydemoApplication extends SpringBootServletInitializer
{
public static void main(String[] args)
{
new JerseydemoApplication().configure(new SpringApplicationBuilder (JerseydemoApplication.class)).run(args);
}
}
Just to add to the answer from Nicholas agreed its an excellent tutorial but if you wish to restructure the project (for example create multiple packages for your resources, models etc) you must ensure that the JerseyConfig class and JerseydemoApplication class are in the same package, otherwise the registration wont work. This is not explicitly mentioned in the tutorial.
I found this while working in intellij ultimate edition and following same tutorial provided by Nicholas above
