Adding common methods to MongoRepositories - spring

I'm trying to add a set of common methods to all MongoRepositories in my project without any success thus far.
I have tried to approach this problem by adding a custom MongoRepositoryFactoryBean but I can't get this to work. Here is the complete code of my very basic test project:
(I've also dumped the project on GitHub over at https://github.com/tentelemed/mongo-demo)
DemoApplication.java
#SpringBootApplication
#EnableMongoRepositories(repositoryFactoryBeanClass = BaseRepositoryFactoryBean.class)
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
Client.java
#Document(collection = "clients")
public class Client {
#Id
private String id;
private String name;
public Client(String id, String name) {
this.id = id;
this.name = name;
}
// Getters & Setters
}
BaseRepository.java
#NoRepositoryBean
public interface BaseRepository<T, ID extends Serializable> extends MongoRepository<T, ID> {
Page<T> mySearch(Query query, Pageable pageable);
}
BaseRepositoryImpl.java
public class BaseRepositoryImpl<T, ID extends Serializable> extends SimpleMongoRepository<T, ID>
implements BaseRepository<T, ID> {
private MongoOperations mongoOperations;
private MongoEntityInformation<T, ID> metadata;
public BaseRepositoryImpl(MongoEntityInformation<T, ID> metadata, MongoOperations mongoOperations) {
super(metadata, mongoOperations);
}
#Override
public Page<T> mySearch(Query query, Pageable pageable) {
long total = mongoOperations.count(query, metadata.getJavaType() );
return new PageImpl<T>(mongoOperations.find(query.with(pageable), metadata.getJavaType()), pageable, total);
}
}
ClientsRepository.java
public interface ClientsRepository extends MongoRepository<Client, String>, BaseRepository<Client, String> {
}
BaseRepositoryFactoryBean.java
public class BaseRepositoryFactoryBean<R extends MongoRepository<T, I>, T, I extends Serializable>
extends MongoRepositoryFactoryBean<R, T, I> {
public BaseRepositoryFactoryBean(Class<? extends R> repositoryInterface) {
super(repositoryInterface);
}
#Override
protected RepositoryFactorySupport getFactoryInstance(MongoOperations operations) {
return new BaseRepositoryFactory<T,I>(operations);
}
private static class BaseRepositoryFactory<T, ID extends Serializable> extends MongoRepositoryFactory {
private MongoOperations mongo;
public BaseRepositoryFactory(MongoOperations mongoOperations) {
super(mongoOperations);
this.mongo = mongoOperations;
}
#SuppressWarnings("unchecked")
protected Object getTargetRepository(RepositoryMetadata metadata) {
TypeInformation<T> information = ClassTypeInformation.from((Class<T>)metadata.getDomainType());
MongoPersistentEntity<T> pe = new BasicMongoPersistentEntity<T>(information);
MongoEntityInformation<T,ID> mongometa = new MappingMongoEntityInformation<T, ID>(pe);
return new BaseRepositoryImpl<T, ID>( mongometa, mongo);
}
protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) {
return BaseRepository.class;
}
}
}
This code produces the following exception upon launch :

Any ideas what I'm doing wrong ?
Thanks!

how to map generics collection with hibernate

i have a wrapper class with a list of generics
#Entity
public class Rubrique<T> {
...
#OneToMany(cascade = CascadeType.ALL, mappedBy = "declaration", fetch = FetchType.LAZY, orphanRemoval = true)
List<T> items = new ArrayList<T>();
...
i use it like that :
#Entity
public class Declar {
Rubrique<ActivConsultant> activConsultant = new Rubrique<ActivConsultant>();
public Rubrique<ActivConsultant> getActivConsultant() {
return activConsultant;
}
and here my Class ActivConsultant :
#Entity
public class ActivConsultant {
#ManyToOne
private Rubrique<?> rubrique;
...
but i can't map these entites with hibernate i have this error :

You cannot use Generics with Hibernate how should Hibernate know which database table the List items should be mapped?
That's also exactly what the error message says:
Property fr.hatvp.parsatorApp.model.Rubrique.items has an unbound type

an explicit target attribute (eg #OneToMany(target=) or use an

Sorry becaue my english is bad.
This is happening because setEnvironment is not getting called.
To fix this either
Option 1: Move Constants.java to com.spring package
OR
Option 2: Add #ComponentScan(basePackages = { "com.spring.util" }) in BootApplication

How to implement ehcache for apache shiro in spring boot correctly and working with ehcache for spring together?

I'm using apache shiro 1.4.0 in Spring Boot 2.1.0 for security management. In both of shiro and spring, I need use the ehCache.
For shiro, I want to use the feature of locking account when error input times of password.
I have a CacheConfig class to integrate the cache manager;
Then I integrated CacheManager into ShiroConfig;
Then I implement the RetryLimitHashedCredentialsMatcher;
At last, run application, Spring Boot start failed.

How can I fix the NPE...I dont't know why it takes out...can any one help me to fix it out, Thanks very much?
I found the crux of which causes exception is in my custom ShrioRealm, where I reference RetryLimitHashedCredentialsMatcher, I can't use it.
At a quick glance, it seems like you need to inject a RetryLimitHashedCredentialsMatcher instead of managing the object outside of Spring, as you are autowiring objects inside of it.

Unsatisfied depedency in spring boot

My model class
package com.darshan.spring.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
#Entity
public class UserInfo {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Integer id;
private String firstName;
private String lastName;
public UserInfo() {
}
public Integer getId() {

}
public void setId(Integer id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
And User Repository class is
package com.darshan.spring.repository;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import com.darshan.spring.model.UserInfo;
#Repository
public interface UserRepository extends JpaRepository<UserInfo, Integer> {

And My Controller class is
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import com.darshan.spring.model.UserInfo;

#RestController
public class UserController {
#Autowired
UserRepository userRepository;
#GetMapping("/allUsers")
public ResponseEntity<List<UserInfo>> getUsers(){
return new ResponseEntity<>(userRepository.findAll(),HttpStatus.OK);

am trying to get the users from UserRepository, The problem here is while starting the spring boot application am getting the following Error

I googled for solution and tried for many ways hower it didn't helped me
i tried #JpaRepositoryConfigaration annotation something like that
You need to check whether you are scanning the package com.darshan.spring.model where your UserInfo resides as part of the application's #ComponentScan and #EntityScan
In your main class or a config class you add #EntityScann("com.darshan.spring.model"), because it tell you that it can not manage your entity UserInfo.
#RishikeshDhokare thanks for that headsup on #EntityScan("com.darshan.*") it worked for me . #ComponentScan would also scan for the beans right ? Why we need to again mentioning #EntityScan
