我正在尝试将 springfox-swagger 添加到我的 Spring MVC 项目中。我有以下配置:

@Configuration
@EnableSwagger2
@ComponentScan(basePackageClasses = com.mycompany.MyCtrl.class)
public class SpringFoxConfig {

    @Autowired
    private TypeResolver typeResolver;

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2);
    }
}

@Configuration
@EnableWebMvc
@EnableCaching
@EnableAspectJAutoProxy(proxyTargetClass = true)
@ComponentScan(basePackageClasses = { ApplicationConfig.class, AppConfig.class})
@Import(SpringFoxConfig.class)
public class ApplicationConfig extends WebMvcConfigurerAdapter implements CachingConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}

但部署后我无法访问任何控制器,1-5 分钟后我得到以下堆栈跟踪:

 2015-12-24 18:26:46,297 ERROR [org.springframework.web.context.ContextLoader] (MSC service thread 1-5) Context initialization failed: com.google.common.util.concurrent.ExecutionError: java.lang.StackOverflowError

 at springfox.documentation.spi.schema.contexts.ModelContext.hasSeenBefore(ModelContext.java:156) [springfox-spi-2.3.0.jar:2.3.0]

 at springfox.documentation.spi.schema.contexts.ModelContext.parentHasSeenBefore(ModelContext.java:174) [springfox-spi-2.3.0.jar:2.3.0]
at springfox.documentation.spi.schema.contexts.ModelContext.hasSeenBefore(ModelContext.java:157) [springfox-spi-2.3.0.jar:2.3.0]

没有 springfox,我的控制器运行良好。我做错了什么?

当您有一个具有双向引用的主从 DTO 时,我已经看到了这种行为:

class Master {
    List<Detail> details;
}

class Details {
    Master master;
}

此问题的解决方法是将hidden = true属性添加到@ApiParam此类参数的注释中:

ResponseEnitity<?> controller(@ApiParam(hidden = true) @RequestBody Master master) {
}

我相信这是 Springfox 中的一个错误,但我还没有机会报告它。
