NPE in MySQLAdapter only in deployed jar

I am having issue when I deploy the jar in AWS ubuntu server,I have 2 packages in Spring Boot.
#1)core package
#2)Process package
The first package(core) is not containing spring boot dependency and generate the jar using maven package,When I run the code the below code works fine in Intellij. But when I deploy in AWS Ubuntu machine I get Null Pointer Exception for MySQLAdapter Class used in the Process PackageController.
Below is the code
//Code in Process
#SpringBootApplication
public class ProcessApplication
{
#Bean
MySQLAdapter mySQLAdapter() {
MySQLAdapter mySQLAdapter = new MySQLAdapter();
return mySQLAdapter;
}
public static void main(String[] args) {
SpringApplication.run(com.test.ProcessApplication.class, args);
}
}
// Core package jar
public class MySQLAdapter {
private String hostName;
private int port;
private String DBName;
private String username;
private String pwd;
private String secretPwdKey;
private com.test.Util.CryptoUtil cryptoUtil;
public MySQLAdapter() {
hostName = "localhost";
port = 3306;
username = "test";
pwd = "test";
DBName = "test";
secretPwdKey = "test";
cryptoUtil = new com.test.Util.CryptoUtil();
}
}
Is this Null Pointer Exception because of cryptoUtil not getting injected or instantiated?
How can this be solved?
// Controller inside Process package
#RestController
class MyRestController{
#Autowired
MySQLAdapter mySQLAdapter;
#RequestMapping(value = {"/register"}, method = {RequestMethod.POST}, produces = {"application/json"})
#ResponseBody
public RegistrationResponse register(#Valid #RequestBody UserPojo userPojo) {
if (!this.mySQLAdapter.checkClientID(userPojo.getClientID())) { //Null Pointer thrown here
}
}
}

Apache Ignite Cache Store + HikariCP DataSource

I am trying to set up Apache Ignite cache store using PostgreSQL as an external storage.
public class MyCacheStore extends CacheStoreAdapter<String, MyCache> {
private static final String GET_QUERY= "SELECT * FROM ..";
private static final String UPDATE_QUERY = "UPDATE ...";
private static final String DELETE_QUERY = "DELETE FROM ..";
#CacheStoreSessionResource
private CacheStoreSession session;
#Override
public MyCache load(String key) throws CacheLoaderException {
Connection connection = session.attachment();
try (PreparedStatement preparedStatement = connection.prepareStatement(GET_QUERY)) {
// some stuff
}
}
#Override
public void loadCache(IgniteBiInClosure<String, MyCache> clo, Object... args) {
super.loadCache(clo, args);
}
#Override
public void write(Cache.Entry<? extends String, ? extends MyCache> entry) throws CacheWriterException {
Connection connection = session.attachment();
try (PreparedStatement preparedStatement = connection.prepareStatement(UPDATE_QUERY)) {
// some stuff
}
}
#Override
public void delete(Object key) throws CacheWriterException {
Connection connection = session.attachment();
try (PreparedStatement preparedStatement = connection.prepareStatement(DELETE_QUERY)) {
// some stuff
}
}
}
MyCache is a standard class:
public class MyCache implements Serializable {
#QuerySqlField(index = true, name = "id")
private String id;
public MyCache() {
}
public MyCache(String id) {
this.id = id;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
Here is a configuration class
import javax.cache.configuration.Factory;
import javax.cache.configuration.FactoryBuilder;
#Configuration
public class ServiceConfig {
// no problems here
#Bean
#ConfigurationProperties(prefix = "postgre")
DataSource dataSource() {
return DataSourceBuilder
.create()
.build();
}
#Bean
public Ignite igniteInstance(IgniteConfiguration igniteConfiguration) {
return Ignition.start(igniteConfiguration);
}
#Bean
public IgniteConfiguration igniteCfg () {
// some other stuff here
IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setClientMode(true);
CacheConfiguration myCacheConfiguration = new CacheConfiguration("MY_CACHE")
.setIndexedTypes(String.class, MyCache.class)
.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL)
.setReadThrough(true)
.setReadThrough(true)
.setCacheStoreSessionListenerFactories(new MyCacheStoreSessionListenerFactory(dataSource))
.setCacheStoreFactory(FactoryBuilder.factoryOf(MyCacheStore.class));
cfg.setCacheConfiguration(myCacheConfiguration);
return cfg;
}
private static class MyCacheStoreSessionListenerFactory implements Factory {
DataSource dataSource;
MyCacheStoreSessionListenerFactory(DataSource dataSource) {
this.dataSource = dataSource;
}
#Override
public CacheStoreSessionListener create() {
// Data Source
CacheJdbcStoreSessionListener listener = new CacheJdbcStoreSessionListener();
listener.setDataSource(dataSource);
return listener;
}
}
}
And this is what I get in logs:

I have read all official documentation about it and examined many other examples, but can't make it run.
HikariCP is the most popular connection pool library, I can't understand why Ignite throws an exception about not being able to serialize DataSource.
Any advice or idea would be appreciated, thank you!

Since your Cache Store is not serializable, you should not use Factory.factoryOf (which is a no-op wrapper) but instead supply a real serializable factory implementation which will acquire local HikariCP on node and then construct the Cache Store.

Exception in combination of #DirtiesContext and FlywayConfig bean in integration test

I am struggling since yesterday's and you might find duplicate but I tried to add the more details today. please guide me here.

you must add the configuration for flyway

Override Ribbon Server List to get a list of host names from consul

I am trying to override Ribbon Server List to get a list of host names from consul. I have the consul piece working properly(when testing with hardcode values) to get the hostname and port for a service. The issue I am having is when I try to autowire in IClientConfig. I get an exception that IClientConfig bean could not be found. How do I override the ribbon configurations and autowire IClientConfig in the ribbonServerList method.
I have tried following the instructions here at http://projects.spring.io/spring-cloud/spring-cloud.html#_customizing_the_ribbon_client on how to customize ribbon client configuration. I keep getting the following error:
Description:
Parameter 0 of method ribbonServerList in com.intradiem.enterprise.keycloak.config.ConsulRibbonSSLConfig required a bean of type 'com.netflix.client.config.IClientConfig' that could not be found.
Which is causing spring-boot to fail.
Bellow are the classes that I am trying to use to create

#ConditionalOnMissingBean
public ServerList<?> ribbonServerList(IClientConfig clientConfig) {
ConsulSSLServerList serverList = new ConsulSSLServerList(client);
serverList.initWithNiwsConfig(clientConfig);
return serverList;
}
}
ServerList Code:
public class ConsulSSLServerList extends AbstractServerList<Server>

private final ConsulClient client;
private String serviceId = "client";
public ConsulSSLServerList(ConsulClient client) {
this.client = client;
}

It seems like it's not considering #Transactional annotation maybe? But I used #EnableTransactionManagement. Can you see something wrong in my configuration?

SOLVED BUT DON'T KNOW WHY:
I just merge parent and subclass of the JpaConfiguration in JpaBookConfiguration. Now it's working. Don't know why. Can you explain?
