我试图在我的Spring Boot" title="Spring Boot">Spring Boot服务中添加一个jsp页面。我的问题是，每次我尝试转到该页面时，都会显示以下内容：

`Whitelabel Error Page

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

Tue Apr 21 23:16:00 EEST 2015 There was an unexpected error (type=Not Found, status=404). No message available`

我已经在我的application.properties中添加了前缀和sufix：

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

这是我的控制器类：

@Controller
public class MarkerController {
    @RequestMapping(value="/map")
    public String trafficSpy() {
        return "index";
    }
}

我的应用程序类：

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    private static Logger logger = Logger.getLogger(Application.class.getName());
    public static void main(String[] args) {
            logger.info("SPRING VERSION: " + SpringVersion.getVersion());
            SpringApplication.run(Application.class, args);
        }
}

还有index.jsp：

<!DOCTYPE html>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html lang="en">
<body>
    <h1>Hello, World!!!</h1>
    <p>JSTL URL: ${url}</p>
</body>
</html>

这是src文件结构：

├── src
│   ├── main
│   │   ├── java
│   │   │   └── com
│   │   │       └── example
│   │   │           └── internetprogramming
│   │   │               └── myserver
│   │   │                   └── server
│   │   │                       ├── Application.java
│   │   │                       ├── config
│   │   │                       │   └── DatabaseConfig.java
│   │   │                       ├── controller
│   │   │                       │   └── MarkerController.java
│   │   │                       ├── dao
│   │   │                       │   ├── MarkerDaoImplementation.java
│   │   │                       │   └── MarkerDaoInterface.java
│   │   │                       ├── Marker.java
│   │   │                       └── service
│   │   │                           ├── MarkerServiceImplementation.java
│   │   │                           └── MarkerServiceInterface.java
│   │   ├── resources
│   │   │   └── application.properties
│   │   └── webapp
│   │       └── WEB-INF
│   │           └── jsp
│   │               └── index.jsp

回答：

确保依赖项列表中包含jasper和jstl：

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