【中文标题】尝试使用 Quarkus 从本地 H2 数据库中检索所有行【英文标题】：Trying to retrieve all rows from local H2 database with Quarkus 【发布时间】：2021-06-19 20:09:12 【问题描述】：我正在 Kotlin 中创建一个 Quarkus 项目。我正在尝试在点击“/users”端点的地方实现一个 API，它会返回我在本地数据库中拥有的所有用户。
很遗憾，我遇到了一个错误。堆栈跟踪：

我已经通过将它添加到我的 application.yaml 文件来设置我的本地 H2 数据库连接：
quarkus:
datasource:
db-kind: h2
username: sa
jdbc:
url: "jdbc:h2:mem:default"
flyway:
migrate-at-start: true
此外，我正在使用https://quarkus.io/guides/hibernate-orm-panache，它非常易于使用。我在我的项目中创建了一个用户实体和一个用户存储库。然后我在我的用户资源中使用它们，在那里我定义了 api。
@Path("/users")
class UsersResource
@Inject
lateinit var userRepository: UserRepository
@GET
@Produces(MediaType.APPLICATION_JSON)
fun getAllUsers() : GetAllUsersResponse =
try
GetAllUsersSuccess(userRepository.listAll())
catch (e: NotFoundException)
GetAllUsersFailure(e)
我已经为我的数据库迁移实施了 Flyway。这似乎进展顺利。迁移运行时我也在表中添加一行，可以看到“1行受到影响”，所以我认为Flyway可以访问H2数据库。
你们中有人知道我错过了什么吗？
亲切的问候
【问题讨论】：
你能添加整个堆栈跟踪吗？ 是的，我已经更新了 qn。 【参考方案1】：我发现了问题。我在蛇形大小写中定义了列名，而在驼峰形大小写中定义了我的实体属性。
