利用事务模板TransactionTemplate来手动添加事务
public void addRant(Rant rant) {
transactionTemplate.execute(-?transactionTemplate是注入transactionManager得到的
new TransactionCallback() {-? TransactionCallback()只有一个方法实现doInTransaction,用一个匿名内部类实现
public Object doInTransaction(TransactionStatus ts) { ------?在事务内执行
try {
rantDao.saveRant(rant);
} catch (Exception e) {
ts.setRollbackOnly();------------------?出现异常就回滚
}
return null;
}
}
}
配置文件

class="com.roadrantz.service.RantServiceImpl">

<property name="transactionTemplate ">
