Mybatic and spring-bound transaction management

Original address: http://czj4451.iteye.com/blog/2037759

MyBatis and spring, transaction management more convenient, here is the way to use transactionnal, the wrong place, I hope you point out.

1. After integration with spring, use Spring's transaction management:

A. @Transactional method:

Create the Beans-da-tx.xml file under the Classpath and join the transaction configuration on the basis of Beans-da.xml (series five):

XML code

1. <!--Configure the transaction manager, note that the DataSource and Sqlsessionfactorybean datasource here are consistent, otherwise the transaction will not function--
   <bean id= "TransactionManager"
   class= "Org.springframework.jdbc.datasource.DataSourceTransactionManager" >
   <property name= "DataSource" ref= "DataSource"/>
   </bean>

2. <tx:annotation-driven transaction-manager= "TransactionManager"/><!--transaction annotations driven, classes and methods labeled @transactional will have transactional -

Service class:

Java code

2. @Service ("UserService")
4. Public class UserService {
8. @Autowired
10. Iusermapper mapper;
14. public int batchupdateuserswhenexception () { //non-transactional
16. User user = new User (9, "before exception");
18. int affectedcount = mapper.updateuser (user); //Successful execution
20. User User2 = new User ("after exception");
22. int i = 1/ 0; //Throw run-time exceptions
24. int affectedCount2 = Mapper.updateuser (user2); //Not implemented
26. if (Affectedcount = = 1 && affectedCount2 = = 1) {
28. return 1;
30. }
32. return 0;
34. }
38. @Transactional
40. public int txupdateuserswhenexception () { //transactional
42. User user = new User (9, "before exception");
44. int affectedcount = mapper.updateuser (user); //Rollback due to subsequent exception
46. User User2 = new User ("after exception");
48. int i = 1/ 0; //Throw run-time exception, transaction rollback
50. int affectedCount2 = Mapper.updateuser (user2); //Not implemented
52. if (Affectedcount = = 1 && affectedCount2 = = 1) {
54. return 1;
56. }
58. return 0;
60. }
62. }
