Personally I recommend SerialPort from http://serialio.com- it's not free, but it's well worth the developer (no royalties) licensing fee for any commercial project. Sadly, it is no longer royalty free to deploy, and SerialIO.com seems to have remade themselves as a hardware seller; I had to search for information on SerialPort.
我个人推荐来自http://serialio.com 的SerialPort -它不是免费的，但对于任何商业项目，开发人员（无版税）许可费非常值得。可悲的是，部署不再免版税，SerialIO.com 似乎已经将自己改造成硬件销售商；我不得不搜索有关 SerialPort 的信息。
From personal experience, I strongly recommend againstthe Sun, IBM and RxTx implementations, all of which were unstable in 24/7 use. Refer to my answers on some of the aforementioned questions for details. To be perfectly fair, RxTx may have come a long way since I tried it, though the Sun and IBM implementations were essentially abandoned, even back then.
根据个人经验，我强烈建议不要使用 Sun、IBM 和 RxTx 实现，它们在 24/7 的使用中都不稳定。有关详细信息，请参阅我对上述一些问题的回答。公平地说，自从我尝试 RxTx 以来，它可能已经走了很长一段路，尽管 Sun 和 IBM 实现基本上被放弃了，即使在那时也是如此。
A newer free option that looks promising and may be worth trying is jSSC (Java Simple Serial Connector), as suggested by @Jodes comment.
正如@Jodes 评论所建议的那样，一个看起来很有前景并且可能值得尝试的更新的免费选项是jSSC (Java Simple Serial Connector)。

The Java Communications API (also known as javax.comm) provides applications access to RS-232 hardware (serial ports): http://www.oracle.com/technetwork/java/index-jsp-141752.html
