Springboot项目打包war配置详解

1. 排除内置tomcat依赖

<dependency>
     <groupId>org.springframework.bootgroupId>
     <artifactId>spring-boot-starter-webartifactId>
     <exclusions>
         <exclusion>
             <groupId>org.springframework.bootgroupId>
             <artifactId>spring-boot-starter-tomcatartifactId>
         exclusion>
     exclusions>
 dependency>

2. 添加servlet依赖

<dependency>
    <groupId>jakarta.servletgroupId>
    <artifactId>jakarta.servlet-apiartifactId>
dependency>

3. 修改打包方式

<packaging>warpackaging>

4. 修改主启动类

@SpringBootApplication
public class Springboot3Application extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(Springboot3Application.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Springboot3Application.class);
    }
}
