## 步骤1：继承SpringBootServletInitializer ##

外部容器部署的话，就不能依赖于Application的main函数了，而是要以类似于web.xml文件配置的方式来启动Spring应用上下文，此时我们需要在启动类中继承SpringBootServletInitializer并实现configure方法

package com.test.chaosblade;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
    import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration;
    import org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
    
    /**
     * @description:

     */
    @SpringBootApplication(exclude = {  DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, SecurityAutoConfiguration.class })
    public class ChaosbladeApplication extends SpringBootServletInitializer { 
        public static void main(String[] args) { 
            SpringApplication.run(ChaosbladeApplication.class, args);
        }
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { 
            return builder.sources(this.getClass());
            //此处的ChaosbladeApplication是springboot启动类
        }
    }
