SPRINGBOOT项目 在tomcat上运行

pringboot项目要想在tomcat上运行是需要配置启动类的， 之前查阅过几次都忘记了。今天写项目又忘记了。在这里写博客记录一下

 

 

启动类 继承   SpringBootServletInitializer   重载  SpringApplicationBuilder

　　public static void main(String[] args) {

        ApplicationContext applicationContext = SpringApplication.run(AppRun.class, args);
        SpringContextHolder springContextHolder = new SpringContextHolder();
        springContextHolder.setApplicationContext(applicationContext);
    }

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