谁能清楚地解释java.lang.annotation.RetentionPolicy常量SOURCE、CLASS和运行时间？
我也不确定“保留注释”这个短语是什么意思。
最佳答案
RetentionPolicy.SOURCE: Discard during the compile. These annotations don't make any sense after the compile has completed, so they aren't written to the bytecode.
Example:@Override,@SuppressWarnings
RetentionPolicy.CLASS: Discard during class load. Useful when doing bytecode-level post-processing. Somewhat surprisingly, this is the default.
RetentionPolicy.RUNTIME: Do not discard. The annotation should be available for reflection at runtime. Example:@Deprecated
