Question

我的配置与Quarkus guide相同。我现在可以从数据库中查询，但是尝试insert会产生此exception。我在使用Eclipselink的JPA中非常有经验，所以我知道Entity类不是问题，因为我可以使用标准的JPQL语法来查询数据库。在简单的em.persist(entity)上插入失败。

javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not insert
Caused by: org.postgresql.util.PSQLException: Unsupported Types value: 1,426,407,511

我的pom.xml：

    <dependency>
        <groupId>io.quarkus</groupId>
        <artifactId>quarkus-jdbc-postgresql</artifactId>
    </dependency>

好吧，我解决了自己的问题，比预期的要简单。我将PostresUuidConverter的用法更改为@Type(type = "pg-uuid")，现在一切正常。
