SpringBoot项目如何进行打包部署
前言:
SSM架构下只需要部署多台Tomcat服务器后通过Nginx负载均衡即可解决。而在SpringBoot中并不需要自己部署Tomcat,而是内部已经自带了。所以我们只需要将其打包后启动,然后交给Nginx进行负载均衡即可
前期SSM架构做过的Tomcat集群:Tomcat集群部署流程流程 和 Nginx负载均衡策略:Nginx负载均衡配置、常用策略、场景及特点
那么这里我们要讲的就是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。
(一)首先需要在application.properties当中配置端口以及访问项目名
server.port=8080 : 访问端口8080
server.servlet.context-path=/demo :访问项目名demo 例:http://localhost:8080/demo
#Tomcat server.port=8080 server.servlet.context-path=/demo
(二)marven的pom.xml配置文件(完整版)

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
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>com.imooc.demo.DemoApplication</mainClass>
</configuration>
</plugin>
</plugins>
<build>
(三)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.imooc.demo; 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 DemoApplication extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } @Override//为了打包springboot项目 protected SpringApplicationBuilder configure( SpringApplicationBuilder builder) { return builder.sources(this.getClass()); } }
(四)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
(五)然后到这个jar的根目录下执行java -jar demo-0.0.1-SNAPSHOT.jar
这个执行方式windows和linux上都一样
