spring boot 部署到tomcat

网上很多文章描述过，当我按步骤做时会抛各种错误，最后记录下我的做法(成功发布到本地 Tomcat9 ):

1.将项目的启动类Application.java继承SpringBootServletInitializer并重写configure方法

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.builder.SpringApplicationBuilder;

import org.springframework.boot.web.servlet.MultipartConfigFactory;

import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

import org.springframework.context.annotation.Bean;

import javax.servlet.MultipartConfigElement;

@SpringBootApplication

public class Application extends SpringBootServletInitializer {

	@Override

	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

		return application.sources(Application.class);

	}

	public static void main(String[] args) {

		SpringApplication.run(Application.class, args);

	}

}

2.在pom.xml文件中，project下面增加package标签

<packaging>war</packaging>

完成以上2步我就可以打包了

1.先进入项目根目录(eg: D:\jhipster_project\demo )，执行 mvn clean package ,将项目打包为war包。

2. 将target 目录中的 demo-0.0.1-SNAPSHOT.war 文件复制到你所安装的tomcat目录中webapps目录中,然后去掉工程后边的后缀，变成 demo.war

需要注意的是这样部署的request url需要在端口后加上项目的名字才能正常访问

eg: http://localhost:8080/demo/***

最后记录下我的pom.xml

</project>

其实也可以在创建 spring boot 项目时选择 Packaging:war
