java - 如何在源代码中以编程方式定义 myAnnotationProcessor？

Question

我只是注释的新手。我创建了一个示例 annotationProcessor 来处理我的注释，目前使用命令行脚本“-processor defaultproject.annotations.DefaultProcessor”来使用它。

有什么方法可以从代码内部设置这个处理器吗？

非常感谢萌因

Processor interface说到发现过程:

The tool uses a discovery process to find annotation processors and decide whether or not they should be run. By configuring the tool, the set of potential processors can be controlled. For example, for a JavaCompiler the list of candidate processors to run can be set directly or controlled by a search path used for a service-style lookup. Other tool implementations may have different configuration mechanisms, such as command line options; for details, refer to the particular tool's documentation.

在类路径中定义处理器的最佳选择是提供一个 META-INF/services/javax.annotation.processing.Processor 文件，其中包含文本 defaultproject.annotations.DefaultProcessor.

(假设您的工具链支持此机制。这最终取决于编译器/工具/IDE。)
