springboot(8)——SpringBoot项目打war包

一、pom.xml中修改成war打包方式

 <packaging>warpackaging>

二、移除嵌入式tomcat插件两种方式

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


<dependency>
    <groupId>org.apache.tomcatgroupId>
    <artifactId>tomcat-servlet-apiartifactId>
    <scope>providedscope>
dependency>

三、添加servlet-api的依赖

<dependency>
    <groupId>javax.servletgroupId>
    <artifactId>javax.servlet-apiartifactId>
    <scope>providedscope>
dependency>

四、修改启动类，重写初始化方法

增加war包的启动类， XXXApplication.class 是原来的启动类

public class WarStartApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(XXXApplication.class);
    }
}

五、执行maven install 打包
