Swagger简单使用

Swagger的Controller可以写@Api(tags = “导航名”)，会显示在Swagger网页左侧导航里，下拉可以看到里面的接口。@ApiOperation(“接口名”)。
@ApiVersion({版本号,版本号})。在Swagger网页左侧上面搜索栏里可以搜索版本号。

@Configuration
@EnableSwagger2WebMvc
public class DocConfig implements InitializingBean {
private final OpenApiExtensionResolver openApiExtensionResolver;
    @Autowired
    private ApplicationContext applicationContext;
    @Autowired
    public DocConfig(OpenApiExtensionResolver openApiExtensionResolver) {
        this.openApiExtensionResolver = openApiExtensionResolver;
    }
@Bean
    public Docket createBusinessRestApi() {
        String groupName = "";
        ApiInfo businessApiInfo = new ApiInfoBuilder()
                .title(groupName)
                .description("")
                .contact(new Contact("", "", ""))
                .version("1.0")
                .build();
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName(groupName)
                .apiInfo(businessApiInfo)
                // 设置统一参数，如Header中的参数
                .globalOperationParameters(params())
                .select()
                .apis(RequestHandlerSelectors.basePackage(""))
                .paths(PathSelectors.any())
                .build()
                .extensions(openApiExtensionResolver.buildExtensions(groupName));
    }
    
private List<Parameter> params() {
        ParameterBuilder tokenParam = new ParameterBuilder();
        tokenParam.name("token").description("Token")
                .modelRef(new ModelRef("string")).parameterType("header").required(false).build();
                }
                return Lists.newArrayList(tokenParam.build());
}
