本文介绍了如何利用Spring、Guava和Commons-lang3库来创建ThreadFactory，便于线程池中的线程命名，提高问题定位效率。通过示例代码展示了它们的使用方法，并指出Guava和Commons-lang3提供了设置未捕获异常处理器的功能，增加了额外的错误处理能力。

创建ThreadFactory的集中常见方法

现在大部分都是手动创建线程池，在线程池初始化参数中有个ThreadFactory参数。使用这个参数的目的是创建一系列有规律名字的Thread。这样在查找Bug、跟踪调用栈等等的时候方便些。

如果手动自己实现一个ThreadFactory接口的实现类那就有点重复造轮子了。今天咱们就说说常见的创造ThreadFactory的方法。

Spring
Guava
commons-lang3

Spring

    public static ThreadFactory spring() {
        return new CustomizableThreadFactory("spring-prefix-");
    }

Guava

    public static ThreadFactory guava() {
        return new ThreadFactoryBuilder()
                .setNameFormat("guava-prefix-%d")
                .setUncaughtExceptionHandler((thread, e) -> {
                    log.error("ThreadPool {} 发生异常", thread, e);
                }).build();
    }

输出日志

Commons-lang3

    public static ThreadFactory commonLang() {
        return new ThreadFactoryBuilder()
                .setNameFormat("commonLang-prefix-%d")
                .setUncaughtExceptionHandler((thread, e) -> {
            log.error("ThreadPool {} 发生异常", thread, e);
        }).build();
    }
