springboot has a built-in Tomcat server, which can directly package the project into a jar to run, but sometimes we need to package the project as a war file and deploy it in the web server. The following are the steps to deploy the springboot project as a war project:
1. Modify the packaging tag value in pom.xml to war
2. Create a new subclass that inherits from SpringBootServletInitializer (similar to Spring Boot's startup class), the code is as follows:
package com.aci;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.scheduling.annotation.EnableScheduling;
@SpringBootApplication
@EnableScheduling
@EnableCaching
public class WebApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(WebApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(WebApplication.class);
}
}
3. Modify the value of the start-class child node of the properties node of the pom.xml file to the value of the class created above. The code is as follows:
<properties>
<start-class>com.aci.WebApplication</start-class>
<java.version>1.8</java.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<springboot.version>1.5.9.RELEASE</springboot.version>
<poi.version>3.15</poi.version>
</properties>
