Springboot 採用war包啟動，僅需在啟動類中新增如下所示的程式碼即可：

 1 package com.fanfengping;
 2 
 3 import org.mybatis.spring.annotation.MapperScan;
 4 import org.springframework.boot.SpringApplication;
 5 import org.springframework.boot.autoconfigure.SpringBootApplication;
 6 import org.springframework.boot.builder.SpringApplicationBuilder;
 
 7 import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
 8 
 9 @SpringBootApplication
10 @MapperScan("com.fanfengping.mapper")
11 public class SpringbootAdminApplication extends SpringBootServletInitializer {
12 
13     public static void main(String[] args) {
14         SpringApplication.run(SpringbootAdminApplication.class
 
, args);
15     }
16 
17     @Override
18     public SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
19         return builder.sources(SpringbootAdminApplication.class);
20     }
21 }

　　在工程專案檔案中，修改包輸出方式為 war 包並重命名war包名字為 api.war，如下所示：

 1     <groupId>com.fanfengping</
 
groupId>
 2     <artifactId>springboot-demo</artifactId>
 3     <version>1.0.0</version>
 4     <name>springboot-demo</name>
 5     <description>Springboot WAR 啟動配置</description>
 6     <packaging>war</packaging>
 7 
 8 
 9     <build>
10         <finalName>api</finalName>
11         <plugins>
12             <plugin>
13                 <groupId>org.springframework.boot</groupId>
14                 <artifactId>spring-boot-maven-plugin</artifactId>
15             </plugin>
16         </plugins>
17     </build>

　　執行命令：mvn clean package 將打包後的war包放到tomcat/webapps，啟動tomcat，訪問：http://127.0.0.1:8080/api/ 即可。
