Spring&Hibernate实现声明式事务

通过Spring整合Hibernate并实现Spring的声明使事物管理

使用Hibernate时需要使用org.springframework.orm.hibernate3.HibernateTransactionManager来作为事务管理器

代码如下：

ORM

1. <?xmlversion="1.0"?>
2. <!DOCTYPEhibernate-mappingPUBLIC"-//Hibernate/HibernateMappingDTD3.0//EN"
3. "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
5. <hibernate-mapping>
6. <classname="com.customer.Customer"table="customer"schema="dbo">
8. <idname="username"type="java.lang.String">
9. <columnname="username"length="50"/>
10. </id>
11. <propertyname="password"type="java.lang.String">
12. <columnname="password"length="20"/>
13. </property>
14. </class>
15. </hibernate-mapping>

1. <?xmlversion="1.0"?>
2. <!DOCTYPEhibernate-mappingPUBLIC"-//Hibernate/HibernateMappingDTD3.0//EN"
3. "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
5. <hibernate-mapping>
6. <classname="com.account.Account"table="account"schema="dbo">
7. <idname="ca_id"type="int">
8. <columnname="ca_id"length="4"/>
9. <generatorclass="identity"/>
10. </id>
11. <propertyname="username"type="java.lang.String">
12. <columnname="username"length="50"/>
13. </property>
14. <propertyname="deposit"type="double">
15. <columnname="deposit"length="20"/>
16. </property>
17. </class>
18. </hibernate-mapping>

1. <?xmlversion="1.0"?>
2. <!DOCTYPEhibernate-mappingPUBLIC"-//Hibernate/HibernateMappingDTD3.0//EN"
3. "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
5. <hibernate-mapping>
6. <classname="com.blackList.BlackList"table="blackList"schema="dbo">
7. <idname="id"type="int">
8. <columnname="id"length="4"/>
9. <generatorclass="identity"/>
10. </id>
11. <propertyname="name"type="java.lang.String">
12. <columnname="name"length="20"/>
13. </property>
14. </class>
15. </hibernate-mapping>

BO:

1. packagecom.base;
3. publicinterfaceIBaseBO{
4. }

1. packagecom.customer;
3. importcom.base.IBaseBO;
5. publicclassCustomerimplementsIBaseBO{
6. privateStringusername;
7. privateStringpassword;
8. publicStringgetUsername(){
9. returnusername;
10. }
11. publicvoidsetUsername(Stringusername){
12. this.username=username;
13. }
14. publicStringgetPassword(){
15. returnpassword;
16. }
17. publicvoidsetPassword(Stringpassword){
18. this.password=password;
19. }
20. }

1. packagecom.account;
3. importcom.base.IBaseBO;
5. publicclassAccountimplementsIBaseBO{
6. privateintca_id;
7. privateStringusername;
8. privatedoubledeposit;
9. publicintgetCa_id(){
10. returnca_id;
11. }
12. publicvoidsetCa_id(intca_id){
13. this.ca_id=ca_id;
14. }
15. publicStringgetUsername(){
16. returnusername;
17. }
18. publicvoidsetUsername(Stringusername){
19. this.username=username;
20. }
21. publicdoublegetDeposit(){
22. returndeposit;
23. }
24. publicvoidsetDeposit(doubledeposit){
25. this.deposit=deposit;
26. }
28. }

1. packagecom.blackList;
3. importcom.base.IBaseBO;
5. publicclassBlackListimplementsIBaseBO{
6. privateintid;
7. privateStringname;
8. publicintgetId(){
9. returnid;
10. }
11. publicvoidsetId(intid){
12. this.id=id;
13. }
14. publicStringgetName(){
15. returnname;
16. }
17. publicvoidsetName(Stringname){
18. this.name=name;
19. }
20. }

DAO:

1. packagecom.base;
4. publicinterfaceIBaseDao{
5. publicvoidinsert(IBaseBObo);
6. }

BaseDao在这里使用HibernateTemplate

1. packagecom.base;
3. importorg.springframework.orm.hibernate3.HibernateTemplate;
5. publicclassBaseDaoextendsHibernateTemplateimplementsIBaseDao{
7. publicvoidinsert(IBaseBObo){
8. }
9. }

Dao的代码变得非常简单...

1. packagecom.customer;
3. importcom.base.BaseDao;
4. importcom.base.IBaseBO;
6. publicclassCustomerDaoextendsBaseDao{
7. publicvoidinsert(IBaseBObo){
8. Customercustomer=(Customer)bo;
9. this.save(customer);
10. }
11. }

1. packagecom.account;
3. importcom.base.BaseDao;
4. importcom.base.IBaseBO;
6. publicclassAccountDaoextendsBaseDao{
7. publicvoidinsert(IBaseBObo){
8. Accountaccount=(Account)bo;
9. this.save(account);
10. }
11. }

1. packagecom.blackList;
3. importjava.util.List;
4. importcom.base.BaseDao;
5. importcom.base.IBaseBO;
7. publicclassBlackListDaoextendsBaseDao{
8. publicListquery(){
9. Listlist=null;
10. list=this.find("fromBlackList");
11. returnlist;
12. }
13. publicvoidinsert(IBaseBObo){
14. }
15. }

ManagerService:

1. packagecom.customer.managerService;
3. importjava.sql.SQLException;
5. importcom.base.IBaseBO;
7. publicinterfaceCustomerManagerService{
8. publicvoidinsertCustomer(IBaseBOcustomer,IBaseBOaccount)throwsException;
9. }

1. packagecom.customer.managerService;
3. importjava.sql.SQLException;
4. importjava.util.LinkedHashMap;
5. importjava.util.List;
7. importorg.springframework.jdbc.support.rowset.SqlRowSet;
9. importcom.account.AccountDao;
10. importcom.base.IBaseBO;
11. importcom.blackList.BlackList;
12. importcom.blackList.BlackListDao;
13. importcom.customer.Customer;
14. importcom.customer.CustomerDao;
16. publicclassCustomerManagerServiceImpimplementsCustomerManagerService{
17. privateCustomerDaocustomerDao;
18. privateAccountDaoaccountDao;
19. privateBlackListDaoblackListDao;
20. publicvoidinsertCustomer(IBaseBO_customer,IBaseBO_account)throwsException{
21. Customercustomer=(Customer)_customer;
22. Listlist=blackListDao.query();
23. for(inti=0;i<list.size();i++){
24. BlackListblackList=(BlackList)list.get(i);
25. if(blackList.getName().equals(customer.getUsername())){
26. thrownewSQLException("注册的用户名被检查出存在于黑名单中。");
27. }
28. }
29. customerDao.insert(_customer);
30. accountDao.insert(_account);
31. }
32. publicvoidsetCustomerDao(CustomerDaocustomerDao){
33. this.customerDao=customerDao;
34. }
35. publicvoidsetAccountDao(AccountDaoaccountDao){
36. this.accountDao=accountDao;
37. }
38. publicvoidsetBlackListDao(BlackListDaoblackListDao){
39. this.blackListDao=blackListDao;
40. }
41. }

调用实例：

1. packagecom;
3. importjava.sql.SQLException;
5. importorg.springframework.context.ApplicationContext;
6. importorg.springframework.context.support.ClassPathXmlApplicationContext;
8. importcom.account.Account;
9. importcom.customer.Customer;
10. importcom.customer.managerService.CustomerManagerService;
12. publicclassMain{
13. publicstaticvoidmain(String[]args){
14. ApplicationContextctx=newClassPathXmlApplicationContext("applicationContext.xml");
15. CustomerManagerServicems=(CustomerManagerService)ctx.getBean("customerServiceManager");
17. Customerc=newCustomer();
18. c.setUsername("DD");
19. c.setPassword("12345");
21. Accounta=newAccount();
22. a.setDeposit(0);
23. a.setUsername("hehua");
25. try{
26. ms.insertCustomer(c,a);
27. }catch(Exceptione){
28. e.printStackTrace();
29. }
30. }
31. }
