  按照如下步骤尝试，如果还不行，麻烦发一个邮件到bladejava@qq.com附上帖子地址并说明使用的bladex版本

   1. 添加tomcat依赖

  <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-tomcat</artifactId>
              <scope>provided</scope>
  </dependency>

  


   2. blade-core-boot排除undertow依赖

  <dependency>
              <groupId>org.springblade</groupId>
              <artifactId>blade-core-boot</artifactId>
              <exclusions>
                  <exclusion>
                      <groupId>org.springblade</groupId>
                      <artifactId>blade-core-cloud</artifactId>
                  </exclusion>
                  <exclusion>
                      <groupId>org.springframework.boot</groupId>
                      <artifactId>spring-boot-starter-undertow</artifactId>
                  </exclusion>
              </exclusions>
  </dependency>

    

  3.pom文件修改打包类型为war

  <groupId>org.springblade</groupId>
  <artifactId>BladeX-Boot</artifactId>
  <packaging>war</packaging>
  <version>2.8.2.RELEASE</version>

  


  4.添加war包插件

  <plugin>
                  <groupId>org.apache.maven.plugins</groupId>
                  <artifactId>maven-war-plugin</artifactId>
                  <configuration>
                      <!--如果想在没有web.xml文件的情况下构建WAR，请设置为false。-->
                      <failOnMissingWebXml>false</failOnMissingWebXml>
                  </configuration>
  </plugin>
  

  5.application.yaml添加修改

  #服务器配置

  server:
    port: 80
  spring:
    application:
      name: blade-api
    profiles:
      active: dev
    main:
      allow-bean-definition-overriding: true

    

    6.Application类修改，最重要的一步

  

  
  7.打包

   mvn package -Dmaven.test.skip=true

  


  ======补充说明=====

  打war包的时候，如果工程依赖的是springboot 2.7.x 则需要做额外的一步操作。针对BladeApplication二次开发一下。

  如果是springboot 3.x则无需修改，主要针对以前的版本需要改动。

  比如创建一个BladeXApplication到业务工程，然后拷贝如下代码，之后把启动类的BladeApplication改成BladeXApplication即可：

  package org.springblade.core.launch;

  按照上面的配置结果，tomcat启动获取nacos数据源配置信息时，获取不到值，你们有这个问题吗
