SpringBoot如何使用SpringBootServletInitializer启动呢?

使用外置tomcat启动的实现思路

1.启动类要继承SpringBootServletInitiailzer类，并复写configure()
2.添加本地tomcat并进行配置

默认的启动类要继承SpringBootServletInitiailzer类，并复写configure()方法。

@SpringBootApplication
public class FileuploadApplication extends SpringBootServletInitializer {
 
    public static void main(String[] args) {
        SpringApplication.run(FileuploadApplication.class, args);
    }
 
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return super.configure(builder);
    }
}
 
2.编写SpringBootServletInitializer类子类,并重写configure方法。

public class ServletInitializer extends SpringBootServletInitializer { 
    @Override  
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {  
        return application.sources(SpringBoot04WebJspApplication.class);  
    }  
}

3.启动服务器
