Wir verwenden das Spiel! Framework 2.3 mit Java. Wir haben ein großes Problem in der Produktion, das unsere Anwendungen daran hindert, Daten an Clients zu senden und auszuführen.Play Framework Zu viele offene Dateien
Wir bekommen den gefürchteten "zu viele offene Dateien" -Fehler und haben gegoogelt, aber haben keine Ahnung, wie das zu beheben ist! Es passiert alle paar Tage, hier ist der Fehler:

Dies ist dann die Datenbankverbindung Link verursacht scheitern und es Spiralen nur außer Kontrolle von dort.
Wenn ich laufen:

ich eine ganze Menge von diesen erhalten:

Hier ist die eigentliche API-Aufruf, die ausgeführt werden versucht:
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());
}
Und dann meine DataConfig-Klasse:
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;
}
}
Der Fehler scheint auf dieser Linie in meinem Controller zu sein:
List<Object[]> fixtures = fixturesService.getTodaysFixturesByCompId(compId);
Die fixturesService Methode:
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;
}
Bitte helfen?
Sie haben einen Teil des Stack-Trace ausgelassen, den Teil, der angibt, woher in Ihrem Code die Ausnahme stammt. Bitte poste den COMPLETE Stack Trace sowie den Code. Ohne weiteres würde ich sagen, dass Sie irgendwo Datenbankverbindungen verlieren. I.e. Sie öffnen Verbindungen wiederholt und schließen sie nicht. Mussten Sie irgendwann die Anzahl der Verbindungen, die von der Datenbank unterstützt werden, stark erhöhen? –
Ist dies Ihr Code: 'controllers.APIController.getTojaysFixturesByCompId (APIController.java:1295)'? –
Hallo, ja, es ist diese Zeile: Liste Fixtures = FixturesService.getTodaysFixturesByCompId (compId); - Siehe Bearbeiten oben in Frage –
