springboot project deployed linux server

The main point of this article is

  • How to introduce step by step SpringBoot The project is deployed to a remote server .

Deploy the whole process

This article uses the creation of Executable jar Way to start SpringBoot project .

1、 To configure maven plug-in unit

<packaging>jar</packaging> <!-- become involved jar package -->
<!-- become involved jar The name of the package -->
<!-- Eliminate the interference of test class on package -->

2、mvn package or mvn install

mvn package and mvn install The difference between :

  1. package The code will be compiled , And pack , Finally according to maven Stipulated packaging Way to pack , Finally output to the target directory .
  2. install It also compiles , And pack , But then install The package will be installed in the local warehouse , For other projects .
# perform mvn clean, Remove previous target Catalog
mvn clean
# Switch to project path , perform mvn package Instructions
mvn package
# Output log
[INFO] --- maven-jar-plugin:3.2.0:jar (default-jar) @ fireworks ---
[INFO] Building jar: D:\Java_Project\firework2.0\target\fireworks.jar
[INFO] --- spring-boot-maven-plugin:2.3.5.RELEASE:repackage (repackage) @ fireworks ---
[INFO] Replacing main artifact with repackaged archive
[INFO] ------------------------------------------------------------------------

Final jar Package output to D:\Java_Project\firework2.0\target\ Under the table of contents . Enter this directory , You will find that there are two files :fireworks.jar and fireworks.jar.original.

  • fireworks.jar It's what we call executable jar, contain Compiled classes and all that is needed to run jar rely on , If you want to see what's inside , You can use the following command :
$ jar tvf target/fireworks.jar
  • fireworks.jar.original Much smaller than the former , This is a Maven stay Spring Boot Repackage the original created before jar file , By the command above , You can see that there are no dependencies needed to run , It only contains the compiled .class file .

therefore , If we want to start SpringBoot project , Need to use executable jar, Because it has all the jar rely on , The start command is as follows :

$ java -jar fireworks.jar

3、 take jar The package is uploaded to the remote server

Use here winSCP, Whatever tool you use , As long as the file can be uploaded to the remote server .

4、 Execute on a remote server jar package

nohup java -jar fireworks-0.0.1-SNAPSHOT.jar & # Background start jar

notes : If you've started a project before , Remember to shut down the original process :

ps -ef|grep java
kill -9 pid
