Spring not roll back transaction if exception throws in the application - spring

Question

I developed the application using spring transactions and insert records in the table.
I'm explicitly throwing the exception in DAO class but spring is inserting the record into the table rather than roll back the transaction.
I have created the two applications as below . In Case 1 record is inserted into table even though exception is thrown . But In Case 2 no record is inserted and spring roll back the transaction successfully. Can you explain me the difference between these two applications.
Case 1:
Item.java
public class Item {
int itemNo;
String itemName;
String itemType;
String itemSize;
public int getItemNo() {
return itemNo;
}
public void setItemNo(int itemNo) {
this.itemNo = itemNo;
}
public String getItemName() {
return itemName;
}
public void setItemName(String itemName) {
this.itemName = itemName;
}
public String getItemType() {
return itemType;
}
public void setItemType(String itemType) {
this.itemType = itemType;
}
public String getItemSize() {
return itemSize;
}
public void setItemSize(String itemSize) {
this.itemSize = itemSize;
}
}
ItemDao
#Service
public class ItemDao {
#Autowired
JdbcTemplate jdbcTemplate ;
void insert(Item item){
jdbcTemplate.update("insert into item_test(itemno, itemtype,itemsize,itemname) values (?,?,?,?)", new Object[]{item.getItemNo(),item.getItemType(),item.getItemSize(),item.getItemName()});
int a=2/0;
}
}
ItemService.java
#Service
public class ItemService {
#Autowired
ItemDao itemDao;
#Transactional
public void insert(Item item){
try{
itemDao.insert(item);
}
catch(Exception e){
e.printStackTrace();
}
}
}
Test.java
public class Test {
public static void main(String[] args) {
// TODO Auto-generated method stub
ApplicationContext ct = new ClassPathXmlApplicationContext("spring.xml");
ItemService itemService = ct.getBean("itemService", ItemService.class);
Item item = new Item();
item.setItemNo(1234);
item.setItemName("sofa");
item.setItemSize("4");
item.setItemType("furniture");
itemService.insert(item);
}
}

}
}

Answer 1

Annotate you ItemDao as #Repository instead of #Service
You should execute unit test with spring Transactional context instead of main , for example using TestNG:
#ContextConfiguration(classes = {ConfigurationClass.class})
#ActiveProfiles({"test"})
public class TestItemDAO extends AbstractTransactionalTestNGSpringContextTests {
#Autowired
private ItemDao dao;
#Test
public void testItemDao() {
dao.insert(item);
}
}

Answer 2

Remove the try block, you are trying to handle the exception so this is reason why RollbackException is not cutting the transaction stream.
