springboot部署web容器SpringBootServletInitializer用途

1.jar包中的打包方式根据自己的需要进行修改

2.若打包成war包,则需要继承 org.springframework.boot.context.web.SpringBootServletInitializer类,覆盖其config(SpringApplicationBuilder)方法

3.打包成war的话,如果打包之后的文件中没有web.xml文件的话自己可以加进去一个最简单的web.xml(只有根节点的定义,而没有子元素)，防止因缺乏web.xml文件而部署失败
 

例子：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;

@SpringBootApplication
//若打包成war包,则需要继承SpringBootServletInitializer类,覆盖其configure(SpringApplicationBuilder)方法
public class JpaThymeleafApplication extends SpringBootServletInitializer {
	
	//添加servlet依赖
	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application){
		return application.sources(JpaThymeleafApplication.class);
	}
	
	public static void main(String[] args) {
		SpringApplication.run(JpaThymeleafApplication.class, args);
	}

}
