Question

在我的Spring Boot Web应用程序的Maven生成war文件（包含JSP，javascript，CSS，静态内容等）之后，当我在tomcat的webapp文件夹中部署war并尝试运行它时，页面显示但我的JSP标签没有工作时，它们像在我的页面上显示为文本一样，例如$ {home}包含在其中，但由于不是可变内容而显示，而在嵌入式tomcat中，一切正常 pom.xml依赖项：

    `<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
     </dependency>

    <dependency>
      <groupId>org.apache.tomcat.embed</groupId>
      <artifactId>tomcat-embed-jasper</artifactId>
      <scope>provided</scope>

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




  <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jstl</artifactId>
      <scope>provided</scope>
    </dependency>`

@SpringBootApplication(scanBasePackages={"com"})

     @Override

            //System.setProperty("spring.devtools.restart.enabled", "false");
            return builder.sources(SpringBootWebAppplication.class);

    public static void main(String[] args) {

        SpringApplication.run(SpringBootWebAppplication.class, args);

@GetMapping("/seeds")
    public String dinkachicka(Model model) {
        try{
        String message = txt.getMeString();
        String arr[]=txt.getMeStringArray();

        model.addAttribute("message", message);
        model.addAttribute("first",arr[0]);
        model.addAttribute("second",arr[1]);
        model.addAttribute("third",arr[2]);
        model.addAttribute("fourth",arr[3]);
        model.addAttribute("fifth",arr[4]);

        }
        catch(Exception e){

        return "seeds";

我知道Spring Boot不是制作Web应用程序的正确选择，但现在还是犯错了。请提出任何建议，为什么外部浏览器将我的jsp视为普通HTML而不是嵌入它正确地进行编译时，我已经设置好了 application.properties文件为

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

server.port=8020

当我在tomcat上部署springboot Web应用程序（war文件）时，jsp标签不起作用，但是在春季启动嵌入式tomcat中，该应用程序运行良好
