1.pom.xml中

        <dependency>  
            <groupId>org.springframework.boot</groupId>  
            <artifactId>spring-boot-starter-web</artifactId>  
            <!-- 排除內建容器，排除內建容器匯出成war包可以讓外部容器執行spring-boot專案-->  
            <exclusions>  
                <exclusion>  
                    <groupId>org.springframework.boot</groupId>  
                    <artifactId>spring-boot-starter-tomcat</artifactId>  
                </exclusion>  
            </exclusions>  
        </dependency>
        <!-- 增加servlet-api依賴 -->
        <dependency>  
            <groupId>javax.servlet</groupId>  
            <artifactId>javax.servlet-api</artifactId>  
        </dependency>  
 

2.實現SpringBootServletInitializer介面

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class Application extends SpringBootServletInitializer{
    
    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }
    
     @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // 注意這裡要指向原先用main方法執行的Application啟動類
        return builder.sources(Application.class);
    }
}
 

完成如上配置後既可以採用widflly或者tomcat啟動springboot專案
