Java18的新特性JEP 413: Code Snippets in Java API Documentation,引入一个 @snippet 标签到 JavaDoc 的标准文档生成工具,以简化在 API 文档中包含示例源代码的过程。 以前想在JavaDoc中添加一个方法的使用示例,是这么写的: /** * testCodeInPre * * <P>Use Sample:</P> * <pre>{@code * TestSnippet...
在Java 18 之前,已经支持在 Javadoc 中引入代码片段,这样可以在某些场景下更好的展示描述信息,但是之前的支持功能有限,比如我想高亮代码片段中的某一段代码是无能为力的。现在 Java 18 优化了这个问题,增加了@snippet来引入更高级的代码片段。 在Java 18 之前,使用<pre>{@code ...}</pre>来引入代码片段。
