Whitelabel Error Page Problem accessing Swagger
问题
访问Swagger文档时，我遇到了这个错误：
白标签错误页面 此应用程序没有对 /error 的显式映射，因此您正在看到它作为回退。
2020年9月23日 星期三 09:38:17 BRT 发生了意外错误（类型=未找到，状态=404）。没有可用的消息
我不知道可能是什么原因...

When trying to access the Swagger documentation, I face this error:

I don't know what can be...

请添加这些配置：
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
//Swagger UI property
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
这必须在实现的配置中声明为 "WebMvcConfigurer"。
更多信息请参阅：https://springfox.github.io/springfox/docs/current/
英文:
Please add those configs
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
//Swagger UI property
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
This must be declareted in the config of implementation with "WebMvcConfigurer".

对于使用 Spring Boot 和 SpringFox 3，您只需以下内容：
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
并且 /swagger-ui.html 现在是 /swagger-ui/index.html 或 /swagger-ui。来自文档的说明：
swagger-ui 的位置已从 http://host/context-path/swagger-ui.html 移动到 http://host/context-path/swagger-ui/index.html 或 http://host/context-path/swagger-ui/（缩写）
英文:
For Spring Boot with SpringFox 3 all you need is following:
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
and /swagger-ui.html is now /swagger-ui/index.html or /swagger-ui. From doc
> swagger-ui location has moved from http://host/context-path/swagger-ui.html to http://host/context-path/swagger-ui/index.html OR http://host/context-path/swagger-ui/ for short
