8、Flush类
@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface Flush {
}
看其注释:
The maker annotation that invoke a flush statements via Mapper interface.
(1)maker annotation
(2)invoke a flush statements
(3)via Mapper interface
重点在于第二点,先看invoke的用法:
public Object invoke(Object obj,Object... args)throws IllegalAccessException,IllegalArgumentException,InvocationTargetException
这里的obj对象就是Mapper interface实现类,
