how to get errors(if possible), exceptions,fails,success counts and ids from jdbctemplate batchupdate?

问题

I am using the below code to do the same. Whenever an sql error occurs(eg: number out of range) batch update stops and getting the result(int array) as null. so i added ignore to the update statement.

Now the batch is getting completed ignoring the sqlerror. This time I am getting failureids(ids skipped) and successids(ids processed as well as errors and exceptions). But i want the counts/ids of success,failures,errors,exceptions separately. how do I do that?

Also i added rewriteBatchedStatements=true which helped gain so much time in inserting but updating still has performance issues. Updating 3000 records seems to take around 10 - 20 seconds. How do I overcome this?
