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

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>

public class CustomDTO {
    private String property1;
    private int property2;

    // 省略构造函数、getter和setter方法
}

@RestController
@Api(tags = "Custom API")
public class CustomController {

    @PostMapping("/custom")
    @ApiOperation(value = "Create custom object", notes = "Create a new custom object")
    public ResponseEntity<CustomDTO> createCustomObject(@RequestBody CustomDTO customDTO) {
        // 处理创建自定义对象的逻辑
        return ResponseEntity.ok(customDTO);
    }
}

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.controller"))
                .paths(PathSelectors.any())
                .build()
                .directModelSubstitute(CustomDTO.class, String.class); // 将CustomDTO类的类型解析器设置为String类型
    }
}
