我想抓住并忽略以下tomcat ClientAbortException.因为没有必要为我的程序注意这一点.

知道如何以及在哪里可以捕获此异常？以下是例外情况:

您好，我正在使用下面的 SpringBoot cron 表达式每天运行我的预定作业两次。应该在上午 10 点和下午 4 点运行

@Scheduled(cron = "0 0 10,16 * * *")

我在下午 3:30 启动了 Springboot 应用程序，它在下午 4 点触发了预定的作业，但第二天上午 10 点它没有触发作业

我上面的 cron 表达式有什么问题吗？请注意，这不是 unix cron 表达式。根据 SpringBoot 文档，它只需要 6 个参数。

I understand that i need to set the clientId and subscription name when writing the jms topic subscriber for my durable topics.

But Whats the purpose of setting the clientID when publishing the TOPIC ? I have seen people setting the client Id even for publisher / consumer, but no one explained that why it is required.

ConnectionFactory conFactory =  this.getConnectionFactory();
Connection connection = conFactory.createConnection();

connection.setClientID("WHATS_MY_PURPOSE"); // Why do we need clientID while publishing the TOPIC from consumer / publisher …

对于单行IF语句,以下哪种格式是JAVA标准？请提供JAVA参考以支持该论点.谢谢.

语法-01:

if (counter == 10) response.redirect("www.google.com");

语法-02:

if (counter == 10) {
    response.redirect("www.google.com");
}
