Spring数据查询中子树异常的意外结束

Question

如果“processList”变量为空但抛出错误，则需要获取所有包列表

 @Query(value = "SELECT pd FROM com.nividous.rpa.domain.PackageDeployment pd WHERE (IsEmpty(:processList) or pd.processName in (:processList) )")
 public Page<PackageDeployment> getActiveProcessList(@Param("processList") List<String> 
   processList,Pageable pageable);

Answer 1

您需要添加括号，并且您可能还需要像这样使用 IsEmpty：

@Query(value = "SELECT pd FROM PackageDeployment pd WHERE IsEmpty(:processList) or pd.processName in (:processList)")
public Page<PackageDeployment> getActiveProcessList(@Param("processList") List<String> processList,Pageable pageable);
