Spring Fox（Swagger）2.9.2的自动生成的swagger-ui未显示Interactive API

Question

使用Spring Fox 2.9.2和Spring Boot 2.1.5 RELEASE，我无法使用由Swagger生成的交互式UI。

这是未扩展的REST端点：

这是REST端点扩展的（您可以看到没有文本字段可在其中键入id）：

                                   .build();
    }
}

[还注意到，我不需要在RestController内使用任何Swagger特定注释（例如，@ApiOperation & @ApiResponse）（我确实尝试将它们放在getByUsingId(Integer id)方法上方，尽管可见，但我的文档仍然没有id文本字段）：

RestController：

@RequestMapping(value = {"/{id}" }, method = RequestMethod.GET, produces = "APPLICATION/JSON")
public ResponseEntity<Object> getByUsingId(@PathVariable(value = "id", required = true) Integer id) 
throws IOException {
       MyResponse response = myDao.getById(id);
       if (response == null) {
           return new ResponseEntity<Object>(HttpStatus.NOT_FOUND);
       }
       return new ResponseEntity<Object>(response, headers, HttpStatus.OK);
}

与旧的Spring Boot 1.5.6 RELEASE项目进行比较，Spring Fox 2.6.1具有更好的UI，并且是交互式的（请注意，展开时具有更好的颜色和可见文本字段：]

这正是我所需要的。

[当我尝试在Spring Boot 2.1.5.RELEASE项目中使用Spring Fox 2.6.1依赖项时，swagger-ui.html页面甚至没有呈现！

正如人们所注意到的，虽然Spring Fox 2.9.2不需要注释，但生成的swagger-ui.html页面不仅看起来有所不同（在颜色等方面），而且甚至没有像我这样的文本字段。第二个示例，Hierarchy Project，则是。

问题：

1. 这是Spring Fox 2.9.2中的可能错误（非交互式文本字段吗？

2. 为什么swagger-ui显得愚蠢（颜色不一样，看上去又不那么锐利，等等）？

Answer 1

想通了...较早版本的Swagger使用了“ Try it Out”按钮来执行REST调用...

现在，这是一个两步过程，您必须先单击“试用”按钮，在文本字段内输入ID，然后单击水平很长的蓝色“执行”按钮。

[这在美学和UI设计方面是一个可怕的变化，并且不像以前的设计那样直观。

Answer 2

尝试将此添加到您的pom.xml中

            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

也是

@Bean
    public Docket apiDocket() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("myPackage"))
                .paths(PathSelectors.any())
                .build();
    }

其中myPackage是包含Spring boot starter类的软件包。

希望它能解决您的问题。 ：）
