该文章是继Java注解解析-基础+运行时注解(RUNTIME)之后,使用注解处理器处理CLASS注解的文章.通过完整的Demo例子介绍整个注解处理器的搭建流程以及注意事项,你将知道如何去搭建自己的注解处理器.前提是你知道如何去写自定义注解,不清楚的可以点击我上面的链接哦- 介绍 顾名思义注解处理器就是javac包中专门用来处理注解的工具.所有的注解处理器都必须继承抽象类AbstractProcessor然后重写它的几个方法.注解处理器是运行在它自己的JVM中.javac启动一个完整Java虚拟机…

依稀记得自己第一次编译*.java文件,第一次运行*.class文件.但是六七年过去了,现在运行java写的程序更多的是用tomcat这种web容器.最近有个小需求,写一个监控zookeeper集群的报警器,当发现集群中节点发生变化时,发出邮件和短信通知运维人员.如果这么一个功能也写成一个web项目放到tomcat里,就有些杀鸡用牛刀了.于是就写了一个jar项目,用 java -jar 运行.占用资源少不说,部署启动很简单,也不占用访问端口.但也遇到了很多问题,才发现自己对java命令还是一知半…

注解的定义格式如下: public @interface 注解名 {定义体} 定义体就是方法的集合,每个方法实则是声明了一个配置参数.方法的名称作为配置参数的名称,方法的返回值类型就是配置参数的类型.和普通的方法不一样,可以通过default关键字来声明配置参数的默认值. 需要注意: (1)此处只能使用public或者默认的defalt两个权限修饰符 (2)配置参数的类型只能使用基本类型(byte,boolean,char,short,int,long,float,double)和String,…

知识点: Java自定义注解.spring aop @aspect的使用 首先我们先介绍Java自定义注解. 在开发过程中,我们实现接口的时候,会出现@Override,有时还会提示写@SuppressWarnings.其实这个就是Java特有的特性,注解. 注解就是某种注解类型的一种实例,我们可以把它用在某个类上进行标注.下面这张图解释注解都是什么? 上图可以看出注解大体分为三种:元注解,标记注解,一般注解: 这一块其他的我就不多做介绍,我们这里主要说一下如何定义自己的注解,在这之前我们必须了…
