Spring 加載多個applicationContext
// java 類 MyDataSource 是 .DAO 類
public static void util(){
ClassPathXmlApplicationContext resource = new ClassPathXmlApplicationContext(new String[]{"applicationContext-database.xml","applicationContext-ibatis.xml","applicationContext-beans.xml"});
BeanFactory factory = resource;
MyDataSource myData=(MyDataSource)factory.getBean("myDataSource");
}
// 三個bean文件配置
applicationContext-database.xml
