springboot項目打包成war包

一、在pom.xml文件中修改

<packaging>war</packaging>

二、移除springboot自帶的tomcat

<!--移除自帶的tomcat-->
<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>

    <!-- 移除以後會報錯，加入下面的依賴 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
         <scope>provided</scope>
    </dependency>

三、在啓動類上繼承SpringBootServletInitializer

添加如下內容

@SpringBootApplicationbr/>@EnableScheduling
public class JavaSayApplication extends SpringBootServletInitializer {

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

/將springboot項目打包成war/
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
// 注意這裏要指向原先用main方法執行的Application啓動類
return builder.sources(JavaSayApplication.class);
}

}

4.

maven clean
maven package
