MyAnnotationProcessor+boolean process(Set annotations, RoundEnvironment roundEnv) 5. 状态图 接下来,我们使用状态图来表示注解处理器的工作流程: StartProcessingFinished 6. 编译与测试 为了测试我们的注解和注解处理器,我们需要创建一个使用了MyCustomAnnotation注解的类。例如: ...
public @interface CustomAnnotation { String value() default ""; // 注解的一个属性 } 2. 实现注解处理器 注解处理器是一种特殊的工具,它在Java编译器编译代码的过程中运行。你需要创建一个类来实现javax.annotation.processing.Processor接口或者继承javax.annotation.processing.AbstractProcessor类。

You control the apt tool by providing it with an AnnotationProcessorFactory that returns custom AnnotationProcessor instances. Each AnnotationProcessor can use the Mirror classes to review the classes going through the tool and output notes, warnings, errors, support files, or new source files (as ...
