如何在Swagger中使用SpringBoot和SpringFox将声明的正文类型从字符串更改为自定义DTO类型

public class UserDTO {
    private String name;
    private int age;
    private String email;

    // Getters and Setters
}

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo"))
                .paths(PathSelectors.any())
                .build();
    }
}

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/users")
@Api(tags = "User Management")
public class UserController {

    @PostMapping
    @ApiOperation(value = "Create a new user")
    public UserDTO createUser(
            @ApiParam(value = "User object to be created", required = true) @RequestBody UserDTO userDTO) {
        // 处理逻辑
        return userDTO;
    }
}
