java - 使用@UseStringTemplate3StatementLocator时，JDBI给出错误 "ORA-00900: invalid SQL statement"

Question

我正在尝试创建一个与 dao.sql.stg 字符串模板文件链接的 DAO 接口(interface)。查询很简单，只是通过id进行选择。

MyDao.groovy:

@UseStringTemplate3StatementLocator
@RegisterMapperFactory(BeanMapperFactory.class)
interface MyDao {
  @SqlQuery
  Foo getFooById(@Bind("fooId") long fooId)
}

MyDao.sql.stg:

group MyDao;

getFooById() ::= <<
    SELECT bar, baz
    FROM foos
    WHERE fooid = (:fooId)
>>

我的后端数据库是oracle。我已经在 Oracle SQL Developer 中尝试过这个查询，它工作得很好，但是当我使用应用程序和 sql.stg 文件运行查询时，它给了我:

java.sql.SQLSyntaxErrorException: ORA-00900: invalid SQL statement

我怀疑它在某种程度上找不到要使用的 sql.stg 文件，即使我在 POM 中包含了资源目录。

如何让 JDBI 找到正确的 sql.stg 字符串模板文件？我遵循了此应用中其他 DAO 的示例，它们使用完全相同的设置。

编辑:请注意，如果我将查询字符串硬编码到 DAO 接口(interface)中的 @SqlQuery 注释中，而不是使用 stringtemplate 文件，那么它可以正常工作。所以问题肯定是dao无法正确找到或处理stringtemplate文件。这是完整的堆栈跟踪:

Answer 1

哇。好吧，结果是找不到 stringtemplate 文件，因为它不在与 DAO 的那个包对应的目录中。我以为是的。我的 DAO 在包中:

com.mydomain.mypackage

表示目录

src/main/java/com/mydomain/mypackage

但是，字符串模板文件位于该目录中

src/main/resources/com.mydomain.mypackage

当它应该在目录中时

src/main/resources/com/mydomain/mypackage

它们在 Intellij 中的显示方式相同。
