I am new to Spring and learning the transaction concepts. Unable to get the @Transactional to work.
Use Case:
Data insert of Employee and Employee details should rollback when getEmployee() throws RunTimeException. But the rollback is not happening.
I am using Oracle database 11g and spring 4.3.1.RELEASE. Below is the standalone java code am running.
public static void main( String[] args ) { AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("spring-bean.xml"); ctx.registerShutdownHook();
Employee emp = new Employee("149518", "Mickey", "Mouse", "15 years", "tennis");
IEmployee empIntfc = (IEmployee)ctx.getBean("empService");
try {
empIntfc.createEmployee(emp);
empIntfc.createEmployeeDetails(emp);
//Below will throw RunTime Exception
empIntfc.getEmployee(2);
}catch (Exception e ) {
e.printStackTrace();
} finally {
ctx.close();
}
}
public class EmployeeService implements IEmployee {
private DataSource dataSource;
private JdbcTemplate jdbcTemplate;
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
jdbcTemplate = new JdbcTemplate(this.dataSource);
}
public JdbcTemplate getJdbcTemplate() {
return jdbcTemplate;
}
@Override
@Transactional
public int createEmployee(Employee emp) {
String sql1 = "INSERT INTO TEST_T1(EMP_ID, EMP_FNAME, EMP_LNAME) values
(?,?,?)";
return getJdbcTemplate().update(sql1, emp.getEmpId(),
emp.getEmpFirstName(), emp.getEmpLastName());
}
@Override
@Transactional
public int createEmployeeDetails(Employee emp) {
String sql = "INSERT INTO TEST_T2(EMP_ID, EXP, SKILLS) values (?,?,?)";
return getJdbcTemplate().update(sql, emp.getEmpId(), emp.getExp(),
emp.getSkills());
}
@Override
@Transactional(readOnly = true, noRollbackFor=RuntimeException.class)
public Employee getEmployee(int empId) {
throw new RuntimeException("Intentional runtime exception");
}
}

Your main method is not transactional ... means : entering 'createEmployee' creates a new transaction and commits it, 'createEmployeeDetails' creates a new transaction and commits it .
