Unable to scan documentation context default java.lang.IllegalStateException: Ambiguous models equality when conditions is empty. at springfox.documentation.spring.web.scanners.ApiModelReader.checkCondition(ApiModelReader.java:618) at springfox.documentation.spring.web.scanners.ApiModelReader.mergeConditions(ApiModelReader.java:385) at springfox.documentation.spring.web.scanners.ApiModelReader.mergeModelBranch(ApiModelReader.java:255)

这个错误通常是由于Springfox的版本不兼容造成的。你可以尝试升级Springfox的版本，或者降级Springfox的版本来解决问题。

另外，你也可以在Springfox中禁用ApiModelReader来解决此问题。你可以在配置类中添加以下代码：

@Bean
public Docket api() {
    return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.any())
            .paths(PathSelectors.any())
            .build()
            .apiInfo(apiInfo())
            .ignoredParameterTypes(YourIgnoredClass.class)
            .directModelSubstitute(YourModel.class, YourModelDto.class)
            .useDefaultResponseMessages(false)
            .enableUrlTemplating(true)
            .alternateTypeRules(
                    newRule(typeResolver.resolve(DeferredResult.class,
                            typeResolver.resolve(ResponseEntity.class, WildcardType.class)),
                            typeResolver.resolve(WildcardType.class)))
            .ignoredParameterTypes(Pageable.class, Slice.class, Sort.class)
            .genericModelSubstitutes(ResponseEntity.class)
            .forCodeGeneration(true)
            .protocols(new HashSet<>(Arrays.asList("http", "https")))
            .tags(new Tag("users", "Operations about users"))
            .additionalModels(typeResolver.resolve(AdditionalModel.class))
            .groupName("test-group")
            .directModelSubstitute(LocalDate.class, Date.class)
            .directModelSubstitute(LocalDateTime.class, Date.class)
            .apiModelReader(null);
}

注意最后一行代码 `apiModelReader(null)` 将禁用ApiModelReader。
