同步锁（锁对象是this），但是出现了一个问题，对于同一个订单的id请求时，在多线程环境下就不应该再进入这段处理代码中， 比如orderId=001时已经进入了 synchronized 中开始执行了，此时又进来一个 orderId=001的请求，因为orderId一致，就不应该再进来。 但实际情况是：因为同步锁对象是 this，而两次请求的对象不同，自然不属于同一个对象，导致 synchronized 并不会起作用。</p></description></item><item><title>Git进阶宝典</title><link>https://hello-github-ui-github-io.onrender.com/posts/git%E8%BF%9B%E9%98%B6%E5%AE%9D%E5%85%B8/</link><pubDate>Thu, 27 Jan

FileInputStream in Java? Answer Even though both FileReader and FileInputStream are used to read data from a file in Java, they are quite different. The main difference between the FileReader and FileInputStream is that one reads data from a character stream while the other reads data from a byte stream. The FileReader automatically converts the raw bytes into characters by using the platform&rsquo;s default character encoding. This means you should use this class if you are reading from a text file that has the same character encoding as the default one.</p></description></item><item><title>Java实现批量重命名文件</title><link>https://hello-github-ui-github-io.onrender.com/posts/java%E5%AE%9E%E7%8E%B0%E6%89%B9%E9%87%8F%E9%87%8D%E5%91%BD%E5%90%8D%E6%96%87%E4%BB%B6/</link><pubDate>Sun,
