o.s.w.s.r.ResourceHttpRequestHandler：Path with "WEB-INF" or "META-INF": [WEB-INF/jsp/index.jsp]

springboot项目，使用jsp作为前端页面。在application.yml配置了jsp所在位置

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

@Controller
@RequestMapping(value = "/user")
public class UserController {
    @Autowired
    UserService userService;

    @RequestMapping(value = "/getAllUser")

    public String getAllUser(){
        //return userService.getAllUser();
        return "index";
    }

}

项目启动spring boot时报错，访问http://localhost:8080/user/getAllUser报错找不到页面

原因是：spring boot默认不使用jsp，需要在pom中引用jsp的编译程序：

            javax.servlet
            jstl
        

        
            org.apache.tomcat.embed
            tomcat-embed-jasper
            provided
        

访问成功
