vpc 虚拟私有云, 有多个服务器组成的虚拟机集群,由管理软件控制,可以实现客户自由调度虚拟机资源的服务器集群 vps 虚拟机私有服务器, 云上虚拟机 vpn 跨 AZ AZ 指 同一数据中心内的不同 vpc ,跨 AZ 则是 服务部署横跨了同数据中心的 vpc, 跨 region 跨地区,指服务部署跨越了不同数据中心,与跨 AZ 不同的是,跨 region 更高可用,不怕天灾人祸,但是管理更加麻烦,统一数据中心可以通过 vip 来统一 服务出口,但跨地区只能通过 dns 之类的技术来实现类似的功能,而且切换延迟更长</description></item><item><title/><link>http://example.org/post/%E4%BD%BF%E7%94%A8-xbootclasspath-%E4%B8%BA-java-jar-%E5%8C%85%E6%B7%BB%E5%8A%A0%E8%BF%90%E8%A1%8C%E5%BA%94%E7%94%A8%E6%97%B6classpath/</link><pubDate>Mon, 01 Jan 0001 00:00:00 +0000</pubDate><guid>http://example.org/post/%E4%BD%BF%E7%94%A8-xbootclasspath-%E4%B8%BA-java-jar-%E5%8C%85%E6%B7%BB%E5%8A%A0%E8%BF%90%E8%A1%8C%E5%BA%94%E7%94%A8%E6%97%B6classpath/</guid><description>使用 -Xbootclasspath 为 java -jar 包添加运行应用时classpath -Xbootclasspath/a:/home/chenzebin/.m2/repository/com/microsoft/sqlserver/mssql-jdbc/6.2.0.jre8/mssql-jdbc-6.2.0.jre8.jar
在命令行 使用 java -X 即可查看
-Xbootclasspath:bootclasspathSpecifies a semicolon-separated list of directories, JAR files, and ZIP archives to search for boot class files. These are used in place of the boot class files included in the Java platform JDK.Applications that use this option for the purpose of overriding a class in rt.jar should not be deployed because doing so would contravene the Java Runtime Environment binary code license.</description></item></channel></rss>
