摘要：
官方代理配置和启动方法：https://github.com/apache/skywalking/blob/master/docs/en/setup/service-agent/java-agent/README.md#table-代理配置属性问题1：以jar包的形式启动启动项目：javajavaagent:E:xxagent
官方给出的agent配置以及启动方式:https://github.com/apache/skywalking/blob/master/docs/en/setup/service-agent/java-agent/README.md#table-of-agent-configuration-properties
问题一:以jar包方式启动boot项目:java -javaagent:E:xxagentskywalking-agent.jar -jar sky-0.1.jar SW_AGENT_NAME=skyboot

找不到jar包解决办法将/optional-plugins下的jar添加到/plugins文件夹下。项目依赖jar不同缺失jar不同添加缺失jar
问题二:
jvm内存异常查看日志打印:

这个问题比较奇葩尝试过调整jvm大小调整jvm启动参数，都不好使最后没办法换JDK试试。解决办法，升级JDK8版本由原版本1.8.0_05升级到了1.8.0_281
