在 Spring jpa/Hibernate 连接异常时退出程序

Question

我希望我的程序在启动时无法连接到数据库时退出。目前此连接使用以下设置：

申请-context.xml

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName">
        <value>${db.driver}</value>
    </property>
    <property name="url">
        <value>${db.url}</value>
    </property>
    <property name="username">
        <value>${db.username}</value>
    </property>
    <property name="password">
        <value>${db.password}</value>
    </property>
</bean>

<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
    <property name="packagesToScan" value="com.template" />
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">false</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
            <prop key="hibernate.ejb.naming_strategy">${naming_strategy}</prop>
            <prop key="hibernate.connection.autoReconnect">true</prop>
            <prop key="hibernate.connection.autoReconnectForPools">true</prop>
            <prop key="hibernate.connection.check-valid-connection-sql">SELECT 1</prop>
            <prop key="hibernate.connection.failOverReadOnly">false</prop>
            <prop key="hibernate.connection.maxReconnects">${maxreconnects}</prop>
            <prop key="hibernate.connection.initialTimeout">${reconnect.interval}</prop>
        </props>
    </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

存储库：

@Repository
public interface Repository extends CrudRepository<Object, String> {

}

我应该在哪里放置代码来捕获由连接失败产生的运行时异常并不明显。如果数据库不存在，是否有任何其他设置可以用来退出。

Answer 1

通常，如果无法在启动时创建 bean，spring 将停止。如果数据库连接失败，那么它将自动停止。你想捕获那个异常，并在退出之前做点什么吗？
