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: * @time: 2020-08-28 15:49 */@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    }}
