我得到没有找到当前的 JDBC 连接。使用 micronaut-data 时出现异常，我指的是https://github.com/tdisanti/micronaut-single-ucp

微航版本

<micronaut.version>2.0.0</micronaut.version>
<micronaut.data.version>1.1.1</micronaut.data.version>

爪哇

@JdbcRepository(dialect = Dialect.ORACLE)
public class BooksDao {
        private final JdbcOperations jdbcOperations;

    @Inject
    public BooksDao (JdbcOperations jdbcOperations) {
        this.jdbcOperations = jdbcOperations;

    }

    @Transactional
public List<Book> get(){
...
}

}

通过在 maven-compiler-plugin 的 annotationProcessorPaths 中添加 micronaut-data-processor 解决了该问题。
