Multiple MongoDB Connectors with SpringBoot REST api - mongodb

I have three databases and I used MongoTemplate to have possibility connect to these databases from my application.
but when I use for example POST Method in Postman, I have error 404, not found.
In the console anything is fine and when I try http://localhost:8080/, also I have this error There was an unexpected error (type=Not Found, status=404).
No message available.
I searched too much and read so many things for example like https://dzone.com/articles/multiple-mongodb-connectors-with-spring-boot, but I could not undesrtood how can I define multiple MongoDB Connectors and fix this problem.

Supporting Multiple data sources of Mongo using Spring data

I am trying to configure two different mongo data sources using spring data.According to my requirement I need to change my scanning of base package dynamically at run time. The user can select the data source for a particular entity via property file by providing datasource and entity mapping.
Eg: entity1:dataSource1, entity2:dataSource2. Depending on this mapping I need to package names and need to replace in the #EnableMongoRepositories(basePackages="xxx.xxx.xxxx") at run time. I tired a lot using both Xml configuration and java configuration.But I could not find a possible way.Could some one please provide a solution for the problem if it is there.I am pasting the Entity classes ,Repositories and Configuration both XML and Java Config

Why #Autowired not working all the time?

Im trying to setup mongodb with SpringBoot and im not using context.xml but trying to configure with configuration class and annotations.
package com.configuration;
import com.mongodb.Mongo;
import com.mongodb.MongoClient;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
#Configuration
#EnableMongoRepositories(basePackages = "com.mongo")
public class MongoConfig extends AbstractMongoConfiguration {
#Override
protected String getDatabaseName() {
return "mongodbname";
}
#Override
public Mongo mongo() throws Exception {
return new MongoClient("127.0.0.1", 27017);
}
#Override
protected String getMappingBasePackage() {
return "com.mongo";
}
}
My repository looks like this :
package com.mongo.repositories;
import com.mongo.documents.Sequence;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.stereotype.Repository;
import java.util.List;
#Repository("sequenceRepository")
public class SequenceRepository{
#Autowired
private MongoTemplate mongoTemplate;
public Sequence findOne(Query query){
return this.mongoTemplate.findOne(query,Sequence.class);
}
public List<Sequence> find(Query query){
return this.mongoTemplate.find(query,Sequence.class);
}
public void save(Sequence object){
this.mongoTemplate.save(object);
}
public void delete(Sequence object){
this.mongoTemplate.remove(object);
}
}
If i use like this in the rest controller it is working properly :
package com.controllers;
import com.mongo.documents.Sequence;
import com.mongo.repositories.SequenceRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class IndexController {
#Autowired
private SequenceRepository sequenceRepository;
#RequestMapping("/")
public String index(){
Sequence sequence = new Sequence();
sequence.setClassName("class.Test");
sequence.setActual(1);
sequenceRepository.save(sequence);
return "index";
}
}
But if i want to use the SequenceRepository inside the Sequence document like this :
package com.mongo.documents;
import com.mongo.repositories.SequenceRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
#Document
public class Sequence {
#Autowired
private SequenceRepository sequenceRepository;
#Id
private String id;
private String className;
private int actual;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getClassName() {
return className;
}
public void setClassName(String className) {
this.className = className;
}
public int getActual() {
return actual;
}
public void setActual(int actual) {
this.actual = actual;
}
public void save(){
this.sequenceRepository.save(this);
}
public void delete(){
this.sequenceRepository.delete(this);
}
}
After that I change the code in the controller to :
package com.controllers;
import com.mongo.documents.Sequence;
import com.mongo.repositories.SequenceRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class IndexController {
#Autowired
private SequenceRepository sequenceRepository;
#RequestMapping("/")
public String index(){
Sequence sequence = new Sequence();
sequence.setClassName("class.Test");
sequence.setActual(1);
sequence.save();
return "index";
}
}
I got a nullPointerExceeption at this point in the save() method.
There is no need to inject your Repository inside your Domain object Sequence as it is really bad design to have a dependency between the domain objects and your repository classes.
To follow some good practices, your Service classes or if you don't need a Service layer, your Controller classes should inject your Repository beans.
In your last code snippet your are already doing it, but the .save() method should be called on your repository SequenceRepository and not on the domain object Sequence.
An example could be the following:
#RestController
public class IndexController {
#Autowired
private SequenceRepository sequenceRepository;
#RequestMapping("/")
public String index(){
Sequence sequence = new Sequence();
sequence.setClassName("class.Test");
sequence.setActual(1);
// now let's save it
sequenceRepository.save(sequence);
return "index";
}
}
You can only autowire Spring-managed components into other Spring-managed components. Your sequence object is not a component (not annotated with #Component, #Service, #Repository or #Controller etc.)
I suggest you follow rieckpil's advice.

Property access of the returned object throws ODatabaseException: Database not set in current thread

I'm using orientdb-object-2.1.9 and trying to setup a basic repository to save and find objects.
But when accessing any property of the returned object from the database, it throws an ODatabaseException, that Database is not set in current thread.
Here is a failing test, showing my usage of the API.
import javax.persistence.Id;
import javax.persistence.Version;
import com.orientechnologies.orient.core.db.OPartitionedDatabasePool;
import com.orientechnologies.orient.object.db.OObjectDatabaseTx;
import org.junit.After;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
public class ObjectDatabaseTest {
private MyObjectAuthorRepository repository;
#Before
public void setUp() {
repository = new MyObjectAuthorRepository();
}
#After
public void tearDown() {
repository.close();
}
#Test
public void testAuthor() {
Author savedAuthor = repository.saveAuthor(new Author("Author Name"));
// a detached object also fails when accessing the property
// Assert.assertEquals("Author Name", savedAuthor.getAuthorName());
Author author = repository.findAuthor();
Assert.assertEquals("Author Name", author.getAuthorName());
}
class MyObjectAuthorRepository {
private final OPartitionedDatabasePool pool;
public MyObjectAuthorRepository() {
pool = new OPartitionedDatabasePool("memory:test", "admin", "admin");
pool.setAutoCreate(true);
try (OObjectDatabaseTx db = new OObjectDatabaseTx(pool.acquire())) {
db.setAutomaticSchemaGeneration(true);
db.getEntityManager().registerEntityClass(Author.class);
}
}
private Author saveAuthor(Author author) {
OObjectDatabaseTx db = new OObjectDatabaseTx(pool.acquire());
try {
db.begin();
Author savedAuthor = db.save(author);
db.commit();
return db.detach(savedAuthor);
} catch (Exception ex) {
db.rollback();
throw ex;
} finally {
db.close();
}
}
public Author findAuthor() {
try (OObjectDatabaseTx db = new OObjectDatabaseTx(pool.acquire())) {
return db.browseClass(Author.class).next();
}
}
public void close() {
pool.close();
}
}
#javax.persistence.Entity
public class Author {
#Id
private String id;
#Version
private Long version;
private String authorName;
public Author() {
}
public Author(String authorName) {
this.authorName = authorName;
}
public String getId() {
return id;
}
public Long getVersion() {
return version;
}
public String getAuthorName() {
return authorName;
}
public void setAuthorName(String authorName) {
this.authorName = authorName;
}
}
}
Please let me know, if the API should be used in a different way or if any other configuration I'm missing here above. It'll be really helpful. Thanks.
