I have to fix the following error. Anyone can help

If we look above exception, we will find that spring container is unable to create or instantiate the bean of type com.website.dev.service.RecordingService.
It is because POJO class is not managed by spring container.
#Autowire annotation will work only those objects which are managed by spring (ie created by the spring container).
you should annotate the RecordingServiceImpl class as Service
#Service
public class RecordingServiceImpl implements RecordingService
and remove #Service("recordingService") from
public interface RecordingService {
//methods
}
RecordingServiceImpl would be managed by Spring container and spring would be able to create the bean.

With a configuration class you could initialize your beans manually, specially if they need custom names.
#Configuration
public class MyCustomConfiguration {
#Bean(name ="headerProcessor")
public ItemProcessor<FileHeader, FileHeader> headerProcessorBean() {
ItemProcessor<FileHeader, FileHeader> myBean = new HeaderProcessor<>();
//Do whaterever you need to initilize your bean

public ItemProcessor<FileDetail, FileDetail> detailProcessorBean() {
ItemProcessor<FileDetail, FileDetail> myBean = new ItemProcessor<>();
//Do whaterever you need to initilize your bean
return myBean;
}
}
In this way these beans will be available for autowiring.
My component is defined as below
#Component("myBo")
public class MyBO {
#Autowired
JpaRepository<MyData, Long> repository;
Spring Data Interface:
public interface MyDataRepository extends JpaRepository<MyData, Long> {

public LocalContainerEntityManagerFactoryBean entityManagerFactory( EntityManagerFactoryBuilder builder, #Qualifier("dmDs") final DataSource dmDs) {
LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean = builder.dataSource(dmDs).packages(new String[]{"my.packages"}).build();
return localContainerEntityManagerFactoryBean;
}
and my test fails with this error

Thanks
You should not autowire JpaRepository<MyData, Long> as is. You should extend it and create your own interface as follows.
public interface MyRepository extends JpaRepository<MyData, Long> {
}
The reason you won't be able to autowire JpaRepository directly is because it is annotated with NoRepositoryBean annotation and that prevents creating an instance of it. It is always recommended to extend the base repo classes and create your own interfaces.
P.S: Do not forget to enable Jpa Repositories on these repo interfaces you are going to create. Otherwise you won't be able to autowire them.
Similar to this in your xml config.
<jpa:repositories base-package="com.acme.repositories"/>
I have some troubles testing my application, whereas it works well in normal execution.
I think it comes from JNDI resources which are not found, but I don't understand why and how to fix it.

Here is my configuration:

public class MyDAOImplTest
{

{
dao = new MyDAOImpl();
}
#Test
public void testTotalUser()
{

Assert.assertEquals(0, result);
}
}
Thanks
You are running in a test case so everything in your Context.xml isn't available as that is only available on tomcat. Why do you need a jndi lookup in your test case anyway? If you want to test your dao use an in-memory database like hsql, h2 or derby and use that instead. Spring has some nice tags to make it easy for you.
<jdbc:embedded-database id="myDataSource" type="H2">
// Add some init scripts here.
</jdbc:embedded-database>
If you really need to do a JNDI lookup you are almost there in your test case. However you have to register a DataSource not a String. So you still will need to construct some (in-memory) datasource and bind that to the mock jndi location
#BeforeClass
public static void initJndi() throws IllegalStateException, NamingException
{
//some test, but doesn't work
// Construct in-memory database
SimpleNamingContextBuilder builder = SimpleNamingContextBuilder.emptyActivatedContextBuilder();
builder.bind("java:comp/env/jdbc/myDatasource", myDatasource); //Actual datasource not a String!
builder.activate();
}
And finally your test is also flawed, you are loading your context but aren't doing anything with it. You are constructing a MyDAOImpl in your #Before method. Why even bother loading the context as you are doing nothing with.
I am using Spring Data JPA (1.3.0.RELEASE) with Spring (3.2.2.RELEASE ) in one project and facing a weird problem. I am using xml based configuration as mentioned below.
<context:annotation-config/>
<context:component-scan base-package="x.y.z.services"/>
Using this configuration to scan the classes decorated with #Component, #Service and #Named annotations.
<jpa:repositories base-package="x.y.z.repo"/>
Using this configuration to scan all interfaces extending JpaRepository. These interfaces are injected in Service classes in the following way.
#Service
public class UserServiceImpl implements UserService {
private UserRepository userRepository;
#Inject
public void setUserRepository(UserRepository userRepository) {
this.userRepository = userRepository;
}
#Override
public List<User> listUsers() {
return userRepository.findAll();
}
}
This configuration works as expected without any issue. But when I add the following configuration I get the BeanCreationException for UserRepository.
<bean id="securityRealm" class="x.y.z.Realm">
<property name="userService">
<bean class="x.y.z.services.UserServiceImpl"/>
</property>
</bean>
And, here is the Java code for Realm and UserRepository.
public class Realm extends AuthorizingRealm implements IRealm {
private UserService userService;
#Inject
public void setUserService(UserService userService) {
this.userService = userService;
}
#Override
protected AuthenticationInfo doGetAuthenticationInfo(
AuthenticationToken token) throws AuthenticationException {
return null;
}
}
public interface UserRepository extends JpaRepository<User, String> {
}
As per above configuration, Spring is able to create the bean for userService but not able to create the UserRepository bean.
I can get this error away by scanning x.y.z.Realm and decorating it with #Service annotation. But it will be a very big constraint and design issue to my application.
AFAICT, Spring is not able to create the bean for UserRepository as it's implementation class is not available and has to be provided by jpa:repositories configuration. I can see that Spring and Spring Data JPA are not working in conjunction.
Can somebody please help me to solve this problem. Below is stacktrace of the exeception.

This was the bug in Spring Data JPA and has been fixed. Please have a look at JIRA issue for resolution.
https://jira.springsource.org/browse/DATAJPA-335
I need to execute a task at 7.05am but I am getting an error.
This is the Controller I created.
#Service("myCtr")
public class MyController {
#Autowired
private TaskScheduler scheduler;
#Async
public void executeTaskT() {
scheduler.schedule(new MyWorker(),
new CronTrigger("5 7 * * *"));
}
}
MyWorker is implementing Runnable simply this way:
[...]
#Override
public void run() {
doWork();
}
private void doWork() { [...]
My scheduler configuration file is imported by the web-application-config.xml:

It appears that Spring can't find your TaskScheduler bean.
With INFO logging, you should be able to find your bean definition in the log during initialization. If not, make sure your configuration file is effectively read by doing further tests.
For your precise need, you can also use the following:
#Service
public class MyService {
#Scheduled(cron = "0 5 7 * * *")
public void myMethod() { ... }
}
With this configuration:
<task:annotation-driven scheduler="myScheduler"/>
<task:scheduler id="myScheduler" pool-size="1000"/>
And assuming MyService is properly seen as a bean, using e.g. Component Scan.
