J'essaie de me connecter à la base de données Firebird en utilisant Spring Data JDBC et Spring Boot. J'ai créé une application simple à l'aide de Spring Tools. Spring Data JDBC ne reconnaît pas le dialecte. Je crois que le problème est que DialectResolver
ne prend pas en charge Firebird.
private static Dialect getDialect(Connection connection) throws SQLException {
DatabaseMetaData metaData = connection.getMetaData();
String name = metaData.getDatabaseProductName().toLowerCase(Locale.ENGLISH);
if (name.contains("hsql")) {
return HsqlDbDialect.INSTANCE;
}
if (name.contains("h2")) {
return H2Dialect.INSTANCE;
}
if (name.contains("mysql")) { // catches also mariadb
return new MySqlDialect(getIdentifierProcessing(metaData));
}
if (name.contains("postgresql")) {
return PostgresDialect.INSTANCE;
}
if (name.contains("Microsoft")) {
return SqlServerDialect.INSTANCE;
}
if (name.contains("db2")) {
return Db2Dialect.INSTANCE;
}
return null;
}
Je suis nouveau sur Java et Spring Boot. Quelqu'un peut-il m'aider à résoudre ce problème?

Je me suis retrouvé face au même problème après la mise à niveau vers SB 2.3.0. L'excellente réponse de Mark (qui btw s'est trouvée dans la documentation sur la migration de Spring Data ), m'a aidé à le résoudre, mais j'ai trouvé que l'ajout de la configuration supplémentaire à META-INF
Était loin d'être idéal.
Ma solution, partant de la réponse originale:
jdbcDialect()
:@Configuration
public class SpringDataJdbcConfiguration extends AbstractJdbcConfiguration {
@Override
public Dialect jdbcDialect(NamedParameterJdbcOperations operations) {
return operations.getJdbcOperations().execute((ConnectionCallback<Dialect>)
connection -> isInformix(connection) ? InformixDialect.INSTANCE : super.jdbcDialect(operations));
}
private boolean isInformix(Connection connection) throws SQLException {
return connection.getMetaData().getDatabaseProductName().toUpperCase().contains("INFORMIX");
}
}
