SpringBoot项目如何进行打包部署-jar包

springboot的打包方式有很多种。有打成war的，有打成jar的，也有直接提交到github，通过jekins进行打包部署的。这里主要介绍如何打成jar进行部署。不推荐用war，因为springboot适合前后端分离，打成jar进行部署更合适。
首先需要在application.yml当中配置端口

[code]server:
port: 8080

maven配置文件

[code]<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</dependencies>

<build>
<finalName>mblog</finalName>
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/**</include>
</includes>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<jvmArguments>-Dfile.encoding=UTF-8</jvmArguments>
<executable>true</executable>
<mainClass>mblog.BootApplication</mainClass>
<includeSystemScope>true</includeSystemScope>
</configuration>
<executions>
<execution>
<configuration>
<classifier>exec</classifier>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>

注意最下面的build这块一定要配置否则打jar的时候会说找不 到主类

在启动类当中加上extends SpringBootServletInitializer并重写configure方法，这是为了打包springboot项目用的。

然后按照顺序运行clean再build,我是用sts

然后就会出来我们需要的jar

然后到这个jar的根目录下执行java -jar smallsystem-0.0.1-SNAPSHOT.jar
这个执行方式windows和linux上都一样

如果是阿里云上的，需要通过阿里云把你指定的端口开放，如果是虚拟机上的，需要把防火墙什么的关掉，开放端口即可。
