本文整理了Java中java.net.URLConnection.setConnectTimeout()方法的一些代码示例，展示了URLConnection.setConnectTimeout()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。URLConnection.setConnectTimeout()方法的具体详情如下：
包路径：java.net.URLConnection
类名称：URLConnection
方法名：setConnectTimeout
[英]Sets the maximum time in milliseconds to wait while connecting. Connecting to a server will fail with a SocketTimeoutException if the timeout elapses before a connection is established. The default value of 0 causes us to do a blocking connect. This does not mean we will never time out, but it probably means you'll get a TCP timeout after several minutes.
Warning: if the hostname resolves to multiple IP addresses, this client will try each in RFC 3484 order. If connecting to each of these addresses fails, multiple timeouts will elapse before the connect attempt throws an exception. Host names that support both IPv6 and IPv4 always have at least 2 IP addresses.
[中]设置连接时等待的最长时间（以毫秒为单位）。如果在建立连接之前超时，连接到服务器将失败，并出现SocketTimeoutException。默认值0导致我们进行阻塞连接。这并不意味着我们永远不会超时，但它可能意味着您将在几分钟后获得TCP超时。
警告：如果主机名解析为多个IP地址，此客户端将按RFC 3484顺序尝试每个IP地址。如果连接到这些地址中的每一个都失败，则在连接尝试引发异常之前，将经过多次超时。同时支持IPv6和IPv4的主机名始终至少有2个IP地址。
