Springboot生成war包

1、pom.xnl中添加配置:

<packaging>war</packaging>

2、pom.xml中添加配置：

spring-boot-starter-web中会包含tomcat，单独设置tomcat的scope为provided，打包时则不会将tomcat打入war包。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

3、修改Application文件或者增加servletInitializer

采用web3.0 规范，没有web.xml ，使用此类实现web.xml的的作用。

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 XiaoBoot01Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(XiaoBoot01Application.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(XiaoBoot01Application.class, args);
    }
}

4、打包并完成
