1、專案中新建目錄webapp/WEB-INF/jsp，並配置依賴

2、application.yml中新增mvc配置

spring:
    mvc:
      view:
      prefix: /WEB-INF/jsp/
      suffix: .jsp
    static-path-pattern: /**  (js、css等檔案放到static目錄下即可)

springboot會掃描預設靜態資源路徑：classpath:/META-INF/resources/，classpath:/resources/，classpath:/static/，classpath:/public/。

3、頁面引用：

4、springboot打war包

（1）首部的jar改為war

 <groupId>com.star</groupId>
    <artifactId>yiyong</artifactId>
    <version>0.0.1-SNAPSHOT</version>
 <packaging>war</packaging>
  <!--<packaging>jar</packaging>-->

（2）pom.xml中新增依賴

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-tomcat</artifactId>
   <scope>provided</scope>
</dependency>
 

（3）修改啟動類

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


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

關鍵之處：繼承SpringBootServletInitializer，重寫了configure方法。

（4）打war包：Maven Prohects -> clean -> package，包在target目錄下。

（5）war包放在webapp目錄下，啟動tomcat訪問即可，親測有效！
