方法详细资料

determineCurrentLookupKey

protected Object determineCurrentLookupKey()

每一次执行SQL语句之前都会执行此方法,以确定本次访问数据库所对应的数据源的key 这里将数据源的bean name作为数据源的key 以方便后续调度数据数据源

指定者:

determineCurrentLookupKey 在类中 org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource

setDataSource

public static void setDataSource(String dataSource)

getDataSource

public static String getDataSource()

clearDataSource

public static void clearDataSource()

getTargetSource

public Map<Object,Object> getTargetSource()
                                   throws NoSuchFieldException,
                                          SecurityException,
                                          IllegalArgumentException,
                                          IllegalAccessException

通过反射获取AbstractRoutingDataSource的targetDataSources属性

返回:

targetDataSources的值

抛出:

NoSuchFieldException

SecurityException

IllegalArgumentException

IllegalAccessException

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

指定者:

setApplicationContext 在接口中 org.springframework.context.ApplicationContextAware

抛出:

org.springframework.beans.BeansException
