我是用的spring集成的
1可以用aop，切面控制事务
2可以用注解控制事务（申明式事务）
3编程式事务

java代码：
申明式事务，关键字@Transactional
@Transactional
public int Save1(String name, String hometown) {
Person person = new Person();
person.setName(name);
person.setHometown(hometown);
int i = personDao.inset(person);
System.out.println("id,getId:" + person.getId());
System.out.println("result:" + i);
System.out.println("person:" + person.toString());
User user = new User();
user.setNickName(name);
user.setLoginName(name);
userDao.save(user);
return 1;
}
编程式事务：
public int hello2(String name, String hometown) {
//编程式事务
// TransactionStatus status = this.getTransactionManager().getTransaction(this.getTxDefinition());
//手动提交
// getTransactionManager().commit(status);
//手动回滚
//getTransactionManager().rollback(status);
TransactionStatus status = this.getTransactionManager().getTransaction(this.getTxDefinition());
try {
Person person = new Person();
person.setName(name);
person.setHometown(hometown);
int i = personDao.inset(person);
System.out.println("id,getId:" + person.getId());
System.out.println("result:" + i);
System.out.println("person:" + person.toString());
User user = new User();
user.setId(46);
user.setNickName(name);
user.setLoginName(name);
userDao.save(user);
getTransactionManager().commit(status);
} catch (Exception e) {
e.printStackTrace();
getTransactionManager().rollback(status);
}
return 1;
}
