I believe the problem is that the DialectResolver doesn't support Firebird. private static Dialect getDialect(Connection connection) throws SQLException { DatabaseMetaData metaData = connection.getMetaData(); String name = metaData.getDatabaseProductName().toLowerCase(Locale.ENGLISH); if (name.contains("hsql")) {

问题 I have a database which is using composite keys. Is it possible to utilize spring-data-jdbc? I tried the milestone version 1.1M2 where I mapped my entity in the following way: class History { @ID @Embedded private CompositeHistoryID id; } Then in my repository class, I added HistoryRepository extends Repository<History,CompositeHistoryID >{ History findByhId(CompositeHistoryID id) } I traced the SQL, and it did not work. The embedded part worked, but the where clause was not correct. It was

问题 I want to be able to map a enum declared in java to an enum created in postgres. For example having the following: CREATE TYPE EYE_COLOR AS ENUM ('BROWN', 'BLUE', 'GREEN'); CREATE TABLE PERSON ( ID INT PRIMARY KEY AUTO_INCREMENT, NAME NVARCHAR2(128) NOT NULL, EYE EYE_COLOR ); In java I have something like this: public enum EyeColor { BROWN, BLUE, GREEN } public class Person { @Id Long id; String name; EyeColor eye; } When I try to do save something to the database like this: personRepository

问题 I have a Spring Boot project that uses Spring Data JDBC. The tests use HSQLDB. My repository tests started failing when I attempted an upgrade to Spring Boot 2.3.0. Spring Data JDBC appears to now quote table and column names. The version of Spring Data JDBC included with Spring Boot 2.2.7 did not. The project at https://github.com/mrgrew/boot230bug demonstrates the difference. Spring Boot 2.3.0 generates INSERT INTO "stats.counter" ("COUNTER_NAME") VALUES (?) which fails. Spring Boot 2.2.7
