Question

In my application I am getting below exception in my business flow very frequently.

My Application Technical specifications are SprinBoot, Java8, SAP Hana as DB, Restful

    org.springframework.transaction.TransactionSystemException: Could not roll back JDBC transaction;
    nested exception is java.sql.SQLException: Connection has already been closed. at org.springframework.jdbc.datasource.DataSourceTransactionManager.doRollback(DataSourceTransactionManager.java:331) at

SAPHanaViewDataSource.datasource.validation-query=select 1 from DUMMY 
SAPHanaViewDataSource.datasource.test-on-borrow=true
SAPHanaViewDataSource.datasource.test-while-idle=false
SAPHanaViewDataSource.datasource.test-on-return=false
SAPHanaViewDataSource.datasource.validation-interval=300000
SAPHanaViewDataSource.datasource.time-between-eviction-runs-millis=300000

SAPHanaViewDataSource.datasource.min-idle=40
SAPHanaViewDataSource.datasource.log-abandoned=true
SAPHanaViewDataSource.datasource.remove-abandoned-timeout=600
SAPHanaViewDataSource.datasource.remove-abandoned=true

以上是application.properties中数据源的数据源配置，我是否按照标准进行了错误的配置？

Can anyone please help me to resolve this issue.
