springboot集成jsp，访问jsp页面下载问题

1、导入相关依赖     （存在jsp页面下载问题，可能是缺少tomcat-embed-jasper的依赖对jsp的支持）

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<parent>         <groupId>org.springframework.boot</groupId>         <artifactId>spring-boot-starter-parent</artifactId>         <version>2.1.8.RELEASE</version>         <relativePath/> <!-- lookup parent from repository -->     </parent>     <dependencies>     <dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-web</artifactId>         </dependency>         <!--springboot自带的tomcat并没有携带tomcat-embed-jasper的依赖(对jsp的支持的依赖)-->     <dependency>             <groupId>org.apache.tomcat.embed</groupId>             <artifactId>tomcat-embed-jasper</artifactId>         </dependency>      </dependencies>

 2、配置application.properties文件

spring.mvc.view.prefix=/pages
spring.mvc.view.suffix=.jsp

3、controller层及springboot启动类

?

1 2 3 4 5 6 7 8 9 10

@Controller public class IndexController {      @RequestMapping("/index")   public ModelAndView index(){              ModelAndView mv=new ModelAndView();       mv.setViewName("/index");       return mv;   } }

 

?

1 2 3 4 5 6 7

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

 注：如果没有使用springboot自带的tomcat，使用外部tomcat的

添加依赖依赖：

?

1 2 3 4 5

<dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-tomcat</artifactId>    //spring-boot-starter-tomcat里面有tomcat-embed-jasper依赖             <scope>provided</scope>         </dependency>
