SpringBoot如何进行项目打包部署

1. 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

首先需要在application.properties当中配置端口

server.port=8080

2. 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">

<configuration>

</configuration>

</plugins>
</build>

</project>
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。
@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
