1.實現功能

將springBoot打包jar包，放入生產環境中執行

2.打包命令

（1）使用cmd命令進入專案根目錄

e:

cd E:\Tools\WorkspaceforMyeclipse\Webproject

（2）執行編譯命令

 mvn clean package -DskipTests
 結果：
[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 ---
[INFO] Building jar: e:\Tools\WorkspaceforMyeclipse\WebSpring\target\web-0.0.1-SNAPSHOT.jar
[INFO]
[INFO] --- spring-boot-maven-plugin:2.0.5.RELEASE:repackage (default) @ web ---

（3）在E:\Tools\WorkspaceforMyeclipse\WebSpring\target目錄下找到

web-0.0.1-SNAPSHOT.jar

3.拷貝到linux目錄

/opt/datas/streamingproject/web-0.0.1-SNAPSHOT.jar

4.執行

java -jar web-0.0.1-SNAPSHOT.jar 

5.報錯分析

（1）報錯

Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].TomcatEmbeddedContext[/imooc]]和之前一樣，因為jar包衝突
	檢視報錯資訊最後，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包衝突

解決：開啟web-0.0.1-SNAPSHOT.jar，刪除lib下面servlet-api-2.5.jar（注意：重新命名servlet-api-2.5.jar為servlet-api-2.5-backup.jar不可行，自己嘗試過。）然後儲存，然後重新上傳

6.測試執行（成功~）
