Answer 1

well the below piece of code which I wrote , worked for me --
In you Main class - load your application context in a static variable - APP_CONTEXT
If you are not using XML based approach - then get the dataSource by auto-wiring it and then you can use below code -
Connection conn = null;
PreparedStatement pstmt= null;
try {
DataSource dataSource = (DataSource) Main.APP_CONTEXT
.getBean("dataSource");
conn = dataSource.getConnection();
pstmt = conn.prepareStatement(" your SQL query to insert ");
pstmtMstr.executeQuery();
} catch (Exception e) {
}finally{
if(pstmt!=null){
pstmt.close();
}if(conn!=null){
conn.close();
}
}

Answer 2

The exception message is very clear - you are invoking this code outside of transaction boundaries. You had committed or rolled back your transaction before this code executed or afterJob is executed in a separate thread.
In both cases you need to define transactional context in which afterJob is executed.

Answer 3

You are directly calling traceRepository.update(trace); which could be a Spring #Repository bean but not annotated with #Transactional.
Instead you can call some Service method that is annotated with #Transactional. From that Service method you can invoke traceRepository.update(trace); which will run in transactional context.
