springboot使用war包部署到外部tomcat

Posted 2021-03-15 架构师成长之路

如果是war包部署到外部tomcat，需要增加SpringBootServletInitializer子类，并重写其configure方法，或者将main函数所在的类继承SpringBootServletInitializer子类，并重写configure方法。

@SpringBootApplication
//继承SpringBootServletInitializer子类
public class Demo2Application extends SpringBootServletInitializer {

    //重写configure方法
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Demo2Application.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(Demo2Application.class, args);
    }
}
