У меня есть приложение загрузки весны, где он слушает очередь RabbitMQ. Проблема в том, что когда я запускаю мое приложение, оно зависает на определенном шаге в спящем режиме, и для продолжения требуется около 10 минут.
Ниже, где он висит

мы сталкиваемся с большой проблемой при разработке нашего приложения, каждый раз, когда мы вносим некоторые изменения, мы должны ждать 8 минут, чтобы проверить наши изменения.
Если вы запускаете приложение в Linux, попробуйте добавить это свойство в командную строку java:
-Djava.security.egd=file:/dev/./urandom
Например:
/usr/bin/java -Xmx75m -Djava.security.egd=file:/dev/./urandom -jar app.jar
У меня была аналогичная проблема, хотя для запуска приложения не потребовалось 8 минут, а всего около 3, и это решило это для меня.
Я думаю, что столкнулся с подобной проблемой. В моем случае время начала было пропорционально размеру базы данных. И вся проблема заключалась в том, что hibernate (мы используем hibernate-core-5.0.2-Final) загружает полные метаданные из БД только для получения значения Dialect.
Теперь мы можем использовать следующее свойство:
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults=false
Но убедитесь, что вы правильно указали значение "spring.jpa.database-platform".
Вот связанная часть файла JdbcEnvironmentInitiator.java:
@Override
public JdbcEnvironment initiateService(Map configurationValues, ServiceRegistryImplementor registry) {
final DialectFactory dialectFactory = registry.getService( DialectFactory.class );
// 'hibernate.temp.use_jdbc_metadata_defaults' is a temporary magic value.
// The need for it is intended to be alleviated with future development, thus it is
// not defined as an Environment constant...
//
// it is used to control whether we should consult the JDBC metadata to determine
// certain Settings default values; it is useful to *not* do this when the database
// may not be available (mainly in tools usage).
boolean useJdbcMetadata = ConfigurationHelper.getBoolean(
"hibernate.temp.use_jdbc_metadata_defaults",
configurationValues,
true
);
if ( useJdbcMetadata ) {
final JdbcConnectionAccess jdbcConnectionAccess = buildJdbcConnectionAccess( configurationValues, registry );
try {
final Connection connection = jdbcConnectionAccess.obtainConnection();
try {
final DatabaseMetaData dbmd = connection.getMetaData();
if ( log.isDebugEnabled() ) {

log.debugf( "JDBC version : %s.%s", dbmd.getJDBCMajorVersion(), dbmd.getJDBCMinorVersion() );
