I am currently developing a Spring MVC application.I have configured a JDBC TransactionManager and I am doing declarative transaction management using AOP XML.However, even if I configure the method to run on a read-only=true, it still commits the transaction.

public class EmployeeService implements EmployeeBaseService{

public EmployeeMapperInterface getEmployeeMapper() {

}
public void setEmployeeMapper(EmployeeMapperInterface employeeMapper) {
this.employeeMapper = employeeMapper;
}
@Override
public Employee getEmployeeById(long empId){
//retrieve from database
List empList = employeeMapper.getEmployeeWithId(empId);
if(empList != null && empList.size()>0){
return (Employee) empList.get(0);
}
return null;
}
@Override
public long saveEmployee(Employee employee){
long empId = 0l;
if(employee.getEmpId()==0){
empId = new Long( employeeMapper.insertEmployee(employee));
}else{
employeeMapper.updateEmployee(employee);
empId = employee.getEmpId();
}
try {
System.out.println("gonna sleep");
Thread.sleep(10);
} catch (InterruptedException e) {
e.printStackTrace();
}
return empId;
}
How do I prevent the auto commit?I have also noticed that even if I don't put any transaction management code, the code still commits. Note, the transaction advice is however,invoked as when I put a no-rollback-for for RuntimeException and then do a 1/0, it correctly commits the data and rolls back if I put the same as rollback-for. I have also tried out the query timeout by putting the thread on sleep, even that doesn't work, but I figure that timeout might be for an actual query, so thats fine. Thanks in advance!
The answer is on Spring MVC Mybatis transaction commit
Detailed stack traces are also available. To summarize,
