1.1　　主要内容

springboot应用启动的三种方式

 

2　　　　个人收获

2.1　　不同的启动方式

通过api调用应用行为方式启动

 //第二种方式启动
        SpringApplication springApplication = new SpringApplication(SpringBootStudyApplication.class);
        //关掉打印logo相关日志
        springApplication.setBannerMode(Banner.Mode.OFF);
        //非wub启动，控制台启动后会关闭，不会一直保持开启状态
        springApplication.setWebApplicationType(WebApplicationType.NONE);
        springApplication.run(args);

 

 

spingapplicationbuilder 链式调用

//第三种方式启动 链式调用
        new SpringApplicationBuilder(SpringBootStudyApplication.class)
                .bannerMode(Banner.Mode.OFF)
                .web(WebApplicationType.NONE).run(args);

 

2.2　　启动方式的一些配置

 　　　　//关掉打印logo相关日志
        springApplication.setBannerMode(Banner.Mode.OFF);
        //非wub启动，控制台启动后会关闭，不会一直保持开启状态，此外还可以通过WebApplicationType的其他变量转换不同的启动方式
        springApplication.setWebApplicationType(WebApplicationType.NONE);

        springApplication.setBannerMode(Banner.Mode.OFF);
        //非wub启动，控制台启动后会关闭，不会一直保持开启状态
        springApplication.setWebApplicationType(WebApplicationType.NONE);
