SpringBoot项目如何进行打包部署

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.properties当中配置端口

server.port=8080 # http://localhost:8088/swagger-ui.html 

marven的配置文件

<?xml version="1.0" encoding="UTF-8"?> <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"> <modelVersion>4.0.0</modelVersion> <groupId>com.weixin</groupId> <artifactId>smallsystem</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>smallsystem</name> <description>smallsystem</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.0.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.2.2</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.2.2</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <mainClass>com.weixin.SmallsystemApplication</mainClass> </configuration> </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。

package com.weixin; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; @SpringBootApplication public class SmallsystemApplication extends SpringBootServletInitializer{ public static void main(String[] args) { SpringApplication.run(SmallsystemApplication.class, args); } @Override//为了打包springboot项目 protected SpringApplicationBuilder configure( SpringApplicationBuilder builder) { return builder.sources(this.getClass()); } } 

然后按照顺序运行mvn clean再mvn install,我是用idea执行的

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。
