Question

我开发了Spring Boot 2.0.0 M3应用程序。一切都很好。但是在更新到Spring Boot 2.0.0 M7（或者最近更新到Spring Boot 2.0.0 M5）之后，SpEL中@Query的{{1}}不再正确编译。例如

@Query("SELECT m FROM com.mypackage.models.Model m WHERE m.status IN 
(:#{T(com.mypackage.utils.Constants).SPECIAL_STATUSES})")
public List<Model> findModelWithSpecialStatuses();

我得到以下异常

org.springframework.dao.InvalidDataAccessApiUsageException: Unknown parameter name : __$synthetic$__1; nested exception is java.lang.IllegalArgumentException: Unknown parameter name : __$synthetic$__1

(:#{T(com.mypackage.utils.Constants).SPECIAL_STATUSES}) - List Object

Answer 1

事实证明，Hibernate的较新版本Spring Boot会优化其查询，因此某些参数不再可见。我发现最快的解决方案就是在not null

中检查@Query的参数

在Spring Boot 2.0.0 M7更新之后，不会在@Query中读取SpEL
