Spring Boot MVC：找不到JSP

我无法WEB-INF/jsp在Spring Boot" title="Spring Boot">Spring Boot Web MVC应用程序下看到自己的视图。

这是我的JSP：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!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=UTF-8">
<title>Insert title here</title>
</head>
<body>
    <ul>
        <%--@elvariable id="users" type="java.util.List"--%>
        <c:forEach items="${utenti}" var="utente">
            <li>
                <c:out value="${utente.getUsername()}"/>
            </li>
        </c:forEach>
    </ul>
</body>
</html>

这是我的控制器：

@Controller
public class UtenteController {
    @Autowired
    private UtenteService utenteService;
    @RequestMapping("/lista_utenti")
    public ModelAndView getListaUtentiView(){
        ModelMap model = new ModelMap();
        model.addAttribute("utenti", this.utenteService.getListaUtenti());
        return new ModelAndView("lista_utenti", model);
    }
}

这是我的application.properties：

# MVC
spring.view.prefix=/WEB-INF/jsp/
spring.view.suffix=.jsp
#Postgres config
spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/DB_Test
spring.datasource.username=postgres
spring.datasource.password=postgres

至少我的主要应用是：

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class SpringWebApplication extends SpringBootServletInitializer{
    public static void main(String[] args) {
        SpringApplication.run(SpringWebApplication.class, args);
    }
    @Override
    protected final SpringApplicationBuilder configure(final SpringApplicationBuilder application) {
        return application.sources(SpringWebApplication.class);
    }
}

如果去，我会得到http://localhost:8080/lista_utenti：

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available

我究竟做错了什么？

回答：

Zio，您确定您已将此pom依赖项包括在内吗？

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

没有这个，我会遇到同样的错误。
