Question

我想用于不同的数据源。但我超越了例外这是我的 spring-config.xml

<mvc:default-servlet-handler />
<mvc:annotation-driven />

<!-- Transaction Manager -->
<tx:annotation-driven />


<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="dataSource" ref="dataSource" />
    <property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="transactionManager1"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="dataSource" ref="dataSource1" />
    <property name="sessionFactory" ref="sessionFactory1" />
</bean>

这是我的例外

@Transactional()
public ArrayList<Integer> getDevicePendingAlerts(int userId, String deviceId) {
    String country = "IND";
    Criteria criteria;
    if (country.equalsIgnoreCase("UK")) {
        criteria = getSessionFactory().getCurrentSession().createCriteria(DeviceAlerts.class);
    } else {
        criteria = getSessionFactory1().getCurrentSession().createCriteria(DeviceAlerts.class);
    }
}

参考：@EnableTransactionManagement annotation with 2 transaction managers

@Transactional(value={METHOD,TYPE}) value的文档

指定交易的限定符值。

可用于确定目标事务管理器，匹配   特定的限定符值（或bean名称）    PlatformTransactionManager bean定义。

您需要添加限定符以指出要使用的事务管理器。只需将@Transactional()更改为@Transactional("transactionManager")或@Transactional("transactionManager1")您想要使用的任何交易管理器。

预期单个匹配bean但找到2：transactionManager1，transactionManager
