我也很蛋疼这种需求。

1. 部署到JavaEE容器

1. 修改启动类，继承 SpringBootServletInitializer 并重写 configure 方法

   public class SpringBootSampleApplication extends SpringBootServletInitializer{
   
       private static final Logger logger = LoggerFactory.getLogger(SpringBootSampleApplication.class);
   
       @Override
       protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
           return builder.sources(this.getClass());
       }
   
   }

2. 修改pom文件中jar 为 war

   <!-- <packaging>jar</packaging> -->
   <packaging>war</packaging>
   

3. 修改pom，排除tomcat插件

   <dependency>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-web</artifactId>
               <exclusions>
                   <exclusion>
                       <groupId>org.springframework.boot</groupId>
                       <artifactId>spring-boot-starter-tomcat</artifactId>
                   </exclusion>
               </exclusions>
   </dependency>
   
   <!-- 排除Tomcat后，需要引入Servlet -->
   <dependency>
       <groupId>javax.servlet</groupId>
       <artifactId>javax.servlet-api</artifactId>
       <scope>provided</scope>
   </dependency>

2. 注意

1. 特别要注意这个 src/main/resource 目录下的exclude的参数, **的意思代表排除所有！！！！

   

2. 然后就是Maven依赖发布到lib目录下
   

   使用文本编辑器打开项目根目录下的.classpath文件
   
<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
<attributes>
<attribute name="maven.pomderived" value="true"/>
<!--就是下面这句了-->
<attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
</attributes>
</classpathentry>
