1.实现功能
将springBoot打包jar包，放入生产环境中运行
2.打包命令
（1）使用cmd命令进入项目根目录
e:
cd E:\Tools\WorkspaceforMyeclipse\Webproject
（2）运行编译命令
mvn clean package -DskipTests
结果：
[INFO] --- maven-surefire-plugin:2.21.0:test (default-test) @ web ---
[INFO] Tests are skipped.
[INFO]
[INFO] --- maven-jar-plugin:3.0.2:jar (default-jar) @ web ---

web-0.0.1-SNAPSHOT.jar3.拷贝到linux目录
/opt/datas/streamingproject/web-0.0.1-SNAPSHOT.jar4.运行
java -jar web-0.0.1-SNAPSHOT.jar 5.报错分析
（1）报错
Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].TomcatEmbeddedContext[/imooc]]和之前一样，因为jar包冲突
查看报错信息最后，有：
jar:file:/opt/datas/streamingproject/web-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/servlet-api-2.5.jar!/javax/servlet/ServletContext.class
jar:file:/opt/datas/streamingproject/web-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/tomcat-embed-core-8.5.34.jar!/javax/servlet/ServletContext.class原因：jar包冲突
解决：打开web-0.0.1-SNAPSHOT.jar，删除lib下面servlet-api-2.5.jar（注意：重命名servlet-api-2.5.jar为servlet-api-2.5-backup.jar不可行，自己尝试过。）然后保存，然后重新上传
6.测试运行（成功~）
