AOP 操作日志注解记录

@Retention(RetentionPolicy.RUNTIME)
@Target( { ElementType.METHOD })
public @interface OperationLogAnnotation {
    //操作描述
    String desc() default "";
    //操作表
    String table() default "";
}

1.这里有获取注解参数的方法。 因为用了security，这是这样取了userId。获取用户id的方法有很多。
2.有获取 注解值的方法。
3.因为json格式的post获取参数，这里从request获取不了，基本因为@PostMapping 因为读了一次流了，调试起来麻烦（没有意义），这里是获取方法的 接参对象用作参数。
