Spring Boot控制器未返回jsp页面

Question

编辑：下面是LatherupApplication应用程序类：

package latherup.com.latherup;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication(scanBasePackages = "latherup.com")
public class LatherupApplication extends SpringBootServletInitializer{

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(LatherupApplication.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(LatherupApplication.class, args);
    }

}

下面是我家控制器：

package latherup.com.latherup;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/home")
public class HomeController {
    @GetMapping("/home")
    public String navigateToHomePage() {
        return "home.jsp";
    }
}

下面是pom.xml文件：

下面是home.jsp：

    <html>
    <head>
        <title>Welcome</title>
        <link href="webjars/bootstrap/3.3.6/css/bootstrap.min.css"
            rel="stylesheet">
    </head>
    <body>
        <div class="container">
            <table class="table table-striped">
                <caption>Your todos are</caption>
                <thead>
                    <tr>
                        <th>Description</th>
                        <th>Target Date</th>
                        <th>Is it Done?</th>
                        <th>Edit</th>
                        <th>Delete</th>
                    </tr>
                </thead>
                <tbody>
                        <tr>
                            <td>Todo 1</td>
                            <td>10/12/2017</td>
                            <td>No</td>
                            <td><a class="btn btn-warning" href="/edit-todo">Edit Todo</a></td>
                            <td><a class="btn btn-warning" href="/delete-todo">Delete Todo</a></td>
                        </tr>
                </tbody>
            </table>
            <div>
                <a class="btn btn-default" href="/add-todo">Add a Todo</a>
                
            </div>
            <script src="webjars/jquery/1.9.1/jquery.min.js"></script>
            <script src="webjars/bootstrap/3.3.6/js/bootstrap.min.js"></script>
        </div>
    </body>
    </html>

应用程序.属性：

spring.mvc.view.prefix=/LATHER-UP/jsp/
spring.mvc.view.suffix=.jsp
logging.level.org.springframework.web=INFO

您正在使用RestController返回JSP。使用controller注释处理视图部件。
