spring 怎么动态配置 连接不同的数据库。oracle 或是mysql

首先配置数据源datasource.xml

<bean id="dataSource" >
 <bean id="a_dataSource" >
然后application.xml配置sqlManClient

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation" value="" />
    </bean>
<bean id="aSqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
    <property name="a_dataSource" ref="assertDataSource" />
    <property name="configLocation" value="" />
</bean>
然后相应的dao写对于的sqlmaoclient

//sqlMapClient
@Resource(name = "sqlMapClient")
    private SqlMapClient sqlMapClient;
 
    @PostConstruct
    public void injectSqlMapClient() {
        super.setSqlMapClient(sqlMapClient);
    }
//===========================
//aSqlMapClient
@Resource(name = "aSqlMapClient")
    private SqlMapClient sqlMapClient;
 
    @PostConstruct
    public void injectSqlMapClient() {
        super.setSqlMapClient(sqlMapClient);
    }
