SpringBoot項目如何進行打包部署

springboot的打包方式有很多種。有打成war的，有打成jar的，也有直接提交到github，通過jekins進行打包部署的。這里主要介紹如何打成jar進行部署。不推薦用war，因為springboot適合前后端分離，打成jar進行部署更合適。
首先需要在application.properties當中配置端口

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這塊一定要配置否則打jar的時候會說找不 到主類

在啟動類當中加上extends SpringBootServletInitializer並重寫configure方法，這是為了打包springboot項目用的。

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//為了打包springboot項目 protected SpringApplicationBuilder configure( SpringApplicationBuilder builder) { return builder.sources(this.getClass()); } } 

然后按照順序運行mvn clean再mvn install,我是用idea執行的

然后就會出來我們需要的jar

然后到這個jar的根目錄下執行java -jar smallsystem-0.0.1-SNAPSHOT.jar
這個執行方式windows和linux上都一樣

如果是阿里雲上的，需要通過阿里雲把你指定的端口開放，如果是虛擬機上的，需要把防火牆什么的關掉，開放端口即可。
