Spring动态获取已注入的对象的方法

1、根据类获取对象

@Autowired

 ApplicationContext context;

GenericMapper<T,String> dao=(GenericMapper<T,String>)context.getBean(TestDaoImpl.class);

2、根据接口获取实现类的对象

@Autowired

ApplicationContext context;

GenericMapper<T,String> dao=(GenericMapper<T,String>)context.getBean(TestInterface.class);
