I'm following Getting Started Guide|Creating a Batch Service.
It uses HyperSQL database as given in the guide.
I have followed the guide as is, but getting the following error:

I'm a beginner and have tried searching for related questions regarding BadSQLGrammarException, but haven't been able to find a solution to my problem.
There is nothing wrong with your code. If you look at the bottom of the stack trace it points that either the table PEOPLE doesn't exist or your user doesn't have permissions to access it.
org.hsqldb.HsqlException: user lacks privilege or object not found: PEOPLE

I have clustered Redis server with 6 nodes in my local machine. But When I try to save a user with my spring boot application I am getting the above mentioned exception in the http response.
I already checked with redis-cli whether the nodes are up and running.

java.lang.NullPointerException is usually caused when you try to use a reference that points to no location in memory (null) as though it were referencing an object. Calling a method on a null reference or trying to access a field of a null reference will trigger a NullPointerException.(https://stackoverflow.com/questions/218384/what-is-a-nullpointerexception-and-how-do-i-fix-it)
I am doing JUnit5 testing using Mockito and here is the full code please have a look and let me know how to fix this :
package hotel.entities;

#InjectMocks Room room = new Room(roomID, roomtype);
#BeforeEach

//booking = new Booking(guest, room,bookedArrival,stayLength,numberOfOccupants,creditCard);
//booking = new checkout(booking);
}
#AfterEach
void tearDown() throws Exception {

#Test
void roomCheckin() {
room.checkin();
assertTrue(room.isAvailable(null, stayLength));
Executable e = () -> room.checkin();
Throwable t = assertThrows(RuntimeException.class, e);
}
#Test
void roomCheckout() {
bookings.add(booking);
room.checkin();
assertEquals(roomID , bookings.size());
assertTrue(room.isAvailable(null, stayLength));
room.checkout(booking);
verify(bookings).remove(booking);
assertTrue(room.isReady());
assertEquals(0,bookings.size());
}
}
I am getting error on this line while I am doing testing:
bookings.add(booking);
please tell me how can I fix this null pointer exception from the code so that it runs properly and my tests get successful.
Here is the complete error trace please guide me how to fix this issue:

Based on your code snippet, it looks like you have two methods i.e. book the hotel and check-out the same.
The general concept of unit test to test the code written in that particular class. So, your end goal will be to test book and checkout method in the different test case.
You are getting java.lang.NullPointerException because your bookings attribute is null due to wrong use of #Spy annotation.
#Spy
List <Booking> bookings = new ArrayList<>();
You should use #Spy as shown above and it will solve your null pointer exception:
You can refer below link to read how to use #Spy # https://www.baeldung.com/mockito-spy

This then caused the database connection link to fail and it just spirals out of control from there.
When I run:

Here is the actual API call that is trying to be executed:
public Result getTodaysFixturesByCompId(Long compId) throws JSONException, ParseException {
Logger.debug("Get Todays Fixtures by compId: " + compId);
List<Object[]> fixtures = fixturesService.getTodaysFixturesByCompId(compId);
// Loop through fixtures and create JSONObject response
ArrayList<JSONObject> fixList = new ArrayList<JSONObject>();
for (int i = 0; i < fixtures.size(); i++) {
JSONObject fixture = new JSONObject();
fixture.put("id", fixtures.get(i)[0]);
fixture.put("fixture_date", fixtures.get(i)[1]);
String fixtureDate = "" + fixtures.get(i)[1];
String fixtureTime = "" + fixtures.get(i)[2];
Logger.debug("fixtureDateTime: " + fixtureDate + " " + fixtureTime);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("Europe/London"));
Date date = sdf.parse(fixtureDate + " " + fixtureTime);
Logger.debug("Parsed date: " + date);
Time timeValue = new Time(date.getTime());
fixture.put("fixture_time", timeValue);
fixture.put("venue", fixtures.get(i)[3]);
fixture.put("country", fixtures.get(i)[4]);
fixture.put("team_id_1", fixtures.get(i)[5]);
fixture.put("team_id_2", fixtures.get(i)[6]);
fixture.put("competition_id", fixtures.get(i)[7]);
fixture.put("sheets_processed", fixtures.get(i)[8]);
fixture.put("team_name_1", fixtures.get(i)[9]);
fixture.put("team_name_2", fixtures.get(i)[10]);
fixList.add(fixture);
}
setAllowAccessOrigin();
return play.mvc.Controller.ok(fixList.toString());
}
And then my DataConfig class:
public class DataConfig {
#SuppressWarnings("serial")
#Bean
public EntityManagerFactory entityManagerFactory() {
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setShowSql(false);
vendorAdapter.setGenerateDdl(true);
LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
entityManagerFactory.setPackagesToScan("models");
entityManagerFactory.setJpaVendorAdapter(vendorAdapter);
entityManagerFactory.setDataSource(dataSource());
entityManagerFactory.afterPropertiesSet();
return entityManagerFactory.getObject();
}
#Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager(entityManagerFactory());
return transactionManager;
}
#Bean
public DataSource dataSource() {
final DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(Play.application().configuration().getString("db.default.driver"));
dataSource.setUrl(Play.application().configuration().getString("db.default.url"));
dataSource.setUsername(Play.application().configuration().getString("db.default.user"));
dataSource.setPassword(Play.application().configuration().getString("db.default.password"));
return dataSource;
}
}
The error seems to be on this line in my controller:
List<Object[]> fixtures = fixturesService.getTodaysFixturesByCompId(compId);
The fixturesService method:
public List<Object[]> getTodaysFixturesByCompId(Long compId) {
String jpql = "select *,(SELECT name FROM teams WHERE id=team_id_1) AS teamname1,(SELECT name FROM teams WHERE id=team_id_2) AS teamname2 from fixtures WHERE (DATE(fixture_date)=DATE(NOW()) AND (competition_id='" + compId + "')) ORDER BY fixture_date,fixture_time";
javax.persistence.Query query = em.createNativeQuery(jpql);
List<Object[]> results = query.getResultList();
return results;
}
Please help?
You leak DB connections. It's not in the code that you describe, try to look where you open connection to the DB and where you close it.
public void onMessage(String msg) {
System.out.printf("Got msg: %s%n", msg);
if(msg.charAt(0)=='a'){
JsonParserFactory factory=JsonParserFactory.getInstance();
JSONParser parser=factory.newJsonParser();
//Map jsonMap=parser.parseJson(msg); uncommenting this line will give the Exception
}
}
this is the code, when I uncomment the commented line, I get this Exception
