执行弹簧启动时出错

Question

我试图使用spring boot执行jsp但是我得到错误而不是显示jsp的主体它正在显示jsp文件名本身。我正在使用的是STS.In STS我选择springstarterproject-> web

我的pom.xml是

这是我的Controller课程

 @Controller
    public class IController {
         @RequestMapping(value="/first")  
            public String bankname(){  
                return "success";  
            } 
    }

启动spring boot应用程序的主程序

@SpringBootApplication
public class SpringbootIndex9Application {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootIndex9Application.class, args);
    }

}

这是我的application.properties

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

而我的success.jsp是

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
welcome
</body>
</html>

我使用的路径是http://localhost:8080/first 项目结构如图所示
