springboot集成jsp，訪問jsp頁面下載問題

1、導入相關依賴     （存在jsp頁面下載問題，可能是缺少tomcat-embed-jasper的依賴對jsp的支持）

<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自帶的tomcat並沒有攜帶tomcat-embed-jasper的依賴(對jsp的支持的依賴)-->
    <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層及springboot啟動類

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

 

@SpringBootApplication

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

 注：如果沒有使用springboot自帶的tomcat，使用外部tomcat的

添加依賴依賴：

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