(1). 编译时Annotation解析过程 编译时Annotation指@Retention为CLASS 的Annotation,由apt(Annotation Processing Tool) 解析自动解析。 需要做的 a) 自定义类集成自AbstractProcessor b) 重写其中的 process 函数 实际是 apt(Annotation Processing Tool) 在编译时自动查找所有继承自 AbstractProcessor 的类,然后调用他们...
Annotation实战【自定义AbstractProcessor】DerDAD 10年前 前言 在使用Java的过程中,每个开发人员都接触过@Override, @Deprecated等等各式各样的注解,这些东西是java最基础的一些原生定义好的annotation。本文通过一个实例演示如果自定义自己的annotation,使得在编译源码代码阶段进行额外操作。案例源码 预热 简单说一下annotatio...
[JAX-RS API Documentation]( [Java Annotation Tutorial](
Metamodel classes are typically generated by annotation processors either at development time or at runtime. Developers of applications that use Criteria queries may generate static metamodel classes by using the persistence provider’s annotation processor or may obtain the metamodel class by either ca...
JSR 269用Annotation Processor在编译期间而不是运行期间处理Annotation, Annotation Processor相当于编译器的一个插件,所以称为插入式注解处理.如果Annotation Processor处理Annotation时(执行process方法)产生了新的Java代码,编译器会再调用一次Annotation Processor,如果第二次处理还有新代码产生,就会接着调用Annotation Processor...
Writing our first Annotation Processor Let’s start writing our first Annotation Processor. Following the general notes on previous section, we build the following class to process the Complexity annotation introduced in part 1: package sdc.assets.annotations.processors; ...
That is simple and is explained in the tutorial you have read when learning to program in Java the first time. Our sample application will be a bit more complex. We will list the files in a directory, read the lines, and count the number of wtf strings. This way we automate the code...
