英文:
Quarkus extension (io.quarkus:quarkus-spring-data-jpa) repository can't return Collection of Strings
问题
我正在将我的服务从SpringBoot堆栈迁移到Quarkus。为什么以下代码在Quarkus中不起作用？这是一个bug吗？
public interface GenericDictionaryRepository extends
JpaRepository<Dictionary, UUID> {
@Query("select distinct(d.type) from Dictionary d order by d.type")
List<String> findAllTypes();
}
错误消息
io.quarkus.builder.BuildException: 构建失败：由于错误而构建失败
[error]: 构建步骤 io.quarkus.spring.data.deployment.SpringDataJPAProcessor#build 抛出异常：java.lang.IllegalStateException: java.lang.String 不是Quarkus索引的一部分
我的Gradle版本属性：
quarkusPluginVersion=1.3.1.Final
quarkusPlatformArtifactId=quarkus-universe-bom
quarkusPlatformGroupId=io.quarkus
quarkusPlatformVersion=1.3.1.Final

I'm migrating my service to Quarkus from SpringBoot stack.
Why the following code doesn't work in Quarkus? Is that a bug?
public interface GenericDictionaryRepository extends
JpaRepository<Dictionary, UUID> {
@Query("select distinct(d.type) from Dictionary d order by d.type")
List<String> findAllTypes();
}
Error message
io.quarkus.builder.BuildException: Build failure: Build failed due to errors
[error]: Build step io.quarkus.spring.data.deployment.SpringDataJPAProcessor#build threw an exception: java.lang.IllegalStateException: java.lang.String was not part of the Quarkus index
My version properties for Gradle:
quarkusPluginVersion=1.3.1.Final
quarkusPlatformArtifactId=quarkus-universe-bom
quarkusPlatformGroupId=io.quarkus
quarkusPlatformVersion=1.3.1.Final

我遇到了相同的问题，这是一个方法命名问题。我不得不在 quarkus 的代码中设置断点，找出哪个方法拼写错误。
在我这里，方法是 findAllOrderByNameAsc，当我使用 findAllByOrderByNameAsc 时，它就起作用了。
要调试应用程序，您需要执行命令 ./mvnw quarkus:dev -Ddebug -Dsuspend=true，然后从您的 IDE 连接到远程。
希望能有所帮助。

I had the same problem and it was a method naming problem. I had to put a break point in the quarkus code to find what method was wrongly spelled.
In my case the method was findAllOrderByNameAsc and when I used findAllByOrderByNameAsc, it worked.
To debug the app you have to execute the command ./mvnw quarkus:dev -Ddebug -Dsuspend=true and connect to remote from your IDE.
Hope it helps.
