【Spring Boot】Spring Boot项目部署到外部Tomcat容器

一、修改项目打包方式为war包

修改pom.xml文件中packaging属性项

<packaging>war</packaging>

修改pom.xml文件增加一个依赖

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

修改启动类

public class SpringBootStartApplication extends SpringBootServletInitializer {
  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    // 注意这里要指向原先用main方法执行的Application启动类
    return builder.sources(Application.class);
  }
}

二、打包

执行Maven打包命令打包即可生成war包，然后即可用于部署Tomcat

mvn clean package
