SpringBoot找不到处理程序方法

我有一个基本的SpringBoot应用程序。使用Spring

Initializer，嵌入式Tomcat，Thymeleaf模板引擎以及作为可执行JAR文件的软件包。

这是主要的课程

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

这是一个控制器

@Controller
public class MockupIndexController {
    @RequestMapping("/mockup/index")
    public String welcome(Map<String, Object> model) {
        return "mockups/index";
    }
}

这是我的 pom.xml

 <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
        <dependency>
             <groupId>com.tdk.iot.core</groupId>
            <artifactId>tdk-core</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
   </dependencies>

但是，当我将其放在URL中时：

http://localhost:8080/mockup/index

我在控制台中获得以下日志

o.s.web.servlet.DispatcherServlet        : Servlet 'dispatcherServlet' configured successfully
o.s.web.servlet.DispatcherServlet        : DispatcherServlet with name 'dispatcherServlet' processing GET request for [/mockup/index]

回答：

我假设在扫描期间未找到您的控制器类，因为它位于默认情况下不会被扫描的软件包中。我猜您的应用程序位于com.tdk.app之类的内容中，而您的控制器位于com.tdk.controller之类的内容中，对吗？如果是，只需将应用程序上移至com.tdk，您的问题就可以解决。
