No mapping for GET /json1/user

I’m working on a SpringMVC project.

my jsonController.java:

@RequestMapping("json1")
@RestController //= @Controller+@ResponseBody
public class jsonController {

    @RequestMapping("user")
    public User data(){
        User user = new User();
        user.setAge(22);
        user.setName("kt");
        return user;
    }
}

my mvcConfig.java:

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = "com.atguigu.json")
public class mvcConfig implements WebMvcConfigurer {
}

my Init.java：

public class Init extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[0];
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{mvcConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

my project structure:

│   ├── java/
│   │   └── com.atguigu/
│   │       ├── json/
│   │       │   ├── jsonController.java

My pom.xml dependency for JSON:

<dependency> 
      <groupId>com.fasterxml.jackson.core</groupId>  
      <artifactId>jackson-databind</artifactId>  
      <version>2.18.0</version> 
    </dependency>

Environment details:

Apache Tomcat/10.1.33
Windows 11
jdk 21.0.4+8-LTS-274
Spring 6.0.2
servlet.api 9.1.0

When I accessed http://localhost:8080/json1/user, I got this error:

[http-nio-8080-exec-7] org.springframework.web.servlet.DispatcherServlet.noHandlerFound No mapping for GET /json1/user

THANK YOU!!!!!!
