APT:使用 Java 进行编译时注释处理

更新.从 Java 1.7 开始:

JSR 269，也称为语言模型 API，有两个基本部分:一个为 Java 编程语言建模的 API，一个用于编写注释处理器的 API.此功能可通过 javac 命令的新选项访问；通过包含 JSR 269 支持，javac 现在的作用类似于 JDK 5 中的 apt 命令.

JSR 269, also known as the Language Model API, has two basic pieces: an API that models the Java programming language, and an API for writing annotation processors. This functionality is accessed through new options to the javac command; by including JSR 269 support, javac now acts analogously to the apt command in JDK 5.
