Java 如何修复OpenJPA查询SQL缓存错误？
我们使用OPENJPA，Tomcat使用Elatic Path软件准备的遗留专有包org.apache.rename.OPENJPA进行操作。我们发现关闭QuerySQLCache对于运行某些查询是必要的。例如，以下非常复杂的查询： 选择t0.CARRIER、t0.CODE、t0.DEFAULT\u COST、t0.ENABLED、t0.GUID、t0.LAST\u MODIFIED\u DATE、t1.UIDPK、t1.TYPE、t2.UIDPK、t2.GUID、t2.NAME、t2.REGION\u STR、t3.UIDPK、t4.CATALOG\u CODE、t4.DEFAULT\u LOCALE、t4.MASTER、t4.NAME、t3.STORECODE、t3.CONTENT\u编码、t3.COUNTRY、t3.CREDIT\u信用卡\u CVV2启用、t3.DEFAULT\u币种、t3.DEFAULT\u LOCALE，t3.DESCRIPTION，t3.DISPLAY\u OUT\u STOCK，t3.EMAIL\u SENDER\u ADDRESS，t3.EMAIL\u SENDER\u NAME，t3.ENABLED，t3.NAME，t3.STORE\u ADMIN\u EMAIL，t3.STORE\u FULL\u CREDIT\u CARDS，t3.STORE\u STATE，t3.STORE\u TYPE，t3.SUB\u COUNTRY，t3.TIMEZONE，t3.URL，t5.OBJECT.UID，t5.UID，t5.UID，t5.UIDPK，t5.PROPERTY\u KEY，t5.VALUE 从TSHIPPINGSERVICELEVEL t0到t0上的左外连接TshippingCostCalculation方法t1.SCCM_UID=t1.UIDPK到t0上的左外连接TSHIPPINGREGION t2.SHIPPING_REGION_UID=t2.UIDPK到t0上的左外连接TSTORE t3.STORE_UID=t3.UIDPK到t0上的左外连接TLOCALIZEDPROPERTIES t5.UIDPK=t5.OBJECT_UID和？=t5.在t3上键入左外连接TCATALOG t4.CATALOG_UID=t4.UIDPK 其中t0.UIDPK= 导致错误的原因：Java 如何修复OpenJPA查询SQL缓存错误？,java,sql,caching,openjpa,Java,Sql,Caching,Openjpa,我们使用OPENJPA，Tomcat使用Elatic Path软件准备的遗留专有包org.apache.rename.OPENJPA进行操作。我们发现关闭QuerySQLCache对于运行某些查询是必要的。例如，以下非常复杂的查询： 选择t0.CARRIER、t0.CODE、t0.DEFAULT\u COST、t0.ENABLED、t0.GUID、t0.LAST\u MODIFIED\u DATE、t1.UIDPK、t1.TYPE、t2.UIDPK、t2.GUID、t2.NAME、t2.REGI
