1.仅使用ofbiz的实体引擎，程序如下：
boolean beganTrans = true;
Map<String, Object> resignMap = new HashMap<String, Object>();
resignMap.put("userLoginId", "wwww");
resignMap.put("password", "1321313133");
resignMap.put("signDaySeries","0");
resignMap.put("isValidate", "1");
Date date=new Date();
DateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String buildDate=format.format(date);
resignMap.put("regeTime", buildDate);
GenericDelegator delegator = GenericDelegator.getGenericDelegator("default");
try {
if (beganTrans)
beganTrans = TransactionUtil.begin();
GenericValue value=delegator.create("LotteryUser", resignMap);
GenericValue value1=delegator.create("LotteryUser", resignMap);
TransactionUtil.commit(beganTrans);
} catch (Exception e) {
e.printStackTrace();
try {
TransactionUtil.rollback(beganTrans);
} catch (GenericTransactionException e1) {
e1.printStackTrace();
}
resp.getWriter().write("sorry");
}
实体引擎配置如下：

Par exemple :
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
<context:annotation-config />
<tx:advice id="defaultTxAdvice">
<tx:attributes>
<tx:method name="*" rollback-for="Exception" />
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="ao_bo"
expression="(execution(* *..*BoImpl.*(..))) or ( execution(* *..*AoImpl.*(..)) and ( not execution(* *..*AoImpl.mtx_*(..)) ) )" />
<aop:advisor pointcut-ref="ao_bo" advice-ref="defaultTxAdvice" />
</aop:config>
La transaction est configurée et annulée si une exception est levée.

Je n'ai jamais utilisé ce produit auparavant. J'utilise généralement la configuration des transactions d'annotation de Spring. Il semble que les transactions programmatiques soient rarement utilisées de nos jours.
La méthode de configuration est probablement similaire à celle de @BodhiXuguang.
