当我提到如下的特定项目密钥（例如JRA-621）时，它工作正常..
sql.query=select start_date from date_table where personel like (select reporter from jiraissue where pkey like 'JRA-621' )
但是当我想调用当前项目键值时，如下所示，它不起作用：（
sql.query=select start_date from date_table where personel like (select reporter from jiraissue where pkey like '${jira.project.key}' )
我的表情有什么问题？
id personel start_date end_date
