Maven 编译器插件的文档中提到了以下内容:
注解处理器:
要运行的注释处理器的名称.仅适用于 JDK 1.6+ 如果不是设置,则应用默认注释处理器发现过程.
Names of annotation processors to run. Only applies to JDK 1.6+ If not set, the default annotation processors discovery process applies.
这里的默认注释处理器发现过程是什么?除了这个配置标签,还有其他方法可以设置注解处理器吗?
What is the default annotation processors discovery process here? Is there any other way to set up annotation processors than this configuration tag?
我发现入门注释处理工具 (apt) 文档提到了一个默认发现过程,但它适用于 工厂类 而不是处理器,不幸的是它使用 tools.jar来自 JDK 的
和 com.sun
包.这是默认的注释处理器发现过程吗?
I've found that the Getting Started with the Annotation Processing Tool (apt) documentation mentions a default discovery procedure, but it works with factory classes not processors and unfortunately it uses the tools.jar
and com.sun
packages from the JDK. Is this the default annotation processors discovery process?
让编译器可以使用注解处理器的默认方法是在 META-INF/services/javax.annotation 的文件中注册它.processing.Processor
.该文件可以包含许多处理器:每个处理器都在其自己的行上是完全限定的类名,最后有一个换行符.如果未指定任何处理器,编译器将默认使用以这种方式找到的处理器.
The default way to make an annotation processor available to the compiler is to register it in a file in META-INF/services/javax.annotation.processing.Processor
. The file can contain a number of processors: each the fully-qualified class name on its own line, with a newline at the end. The compiler will default to using processors found in this way if none are specified.
