springBoot使用外部Tomcat启动项目

实现思路是：

将springBoot项目自带的tomcat在部署的时候不使用。

方法一：将springBoot自带tomcat编辑成只在编译和测试时使用。

1. 将pom文件中jar改成war,内置tomcat要改成provide

   <dependency>
     <groupId>org.apache.tomcat.embed</groupId>
     <artifactId>tomcat-embed-jasper</artifactId>
     <scope>provided</scope>
   </dependency>

2. 项目的启动类改成如下

   @SpringBootApplication
   @Configuration
   @EnableConfigurationProperties
   public class BaseApplication extends SpringBootServletInitializer {
     
     @Override
     protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
       return application.sources(BaseApplication.class);
     }
   
     public static void main(String[] args) {
       SpringApplication.run(BaseApplication.class, args);
     }
   
   }

方法二：将springBoot内置tomcat移除，添加使用外部tomcat的依赖。

1.重写springbootApp初始化方法

@SpringBootApplication
public class KafkaApplication extends SpringBootServletInitializer {

    //继承初始化类，并重写该方法
    public static void main(String[] args) {
        SpringApplication.run(KafkaApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(KafkaApplication.class);
    }
}

2.修改pom.xml打包方式为war

<packaging>war</packaging>

3.增加pom.xml依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>
4.此方法应该添加此项（我没测试）

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
   <!-- 移除嵌入式tomcat插件 -->
          <exclusions>
              <exclusion>
                  <groupId>org.springframework.boot</groupId>
                  <artifactId>spring-boot-starter-tomcat</artifactId>
              </exclusion>
          </exclusions>
</dependency>
