SpringBoot訪問doc.html頁面404

默認情況下并不需要添加此配置即可訪問

很多朋友在使用SpringBoot集成swagger-bootstrap-ui后，都無法訪問doc.html界面，此時，你可能需要實現(xiàn)SpringBoot的WebMvcConfigurer接口，添加相關的ResourceHandler,代碼如下：

@SpringBootApplication
public class SwaggerBootstrapUiDemoApplication  implements WebMvcConfigurer{


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

或者

@SpringBootApplication
public class SwaggerBootstrapUiDemoApplication  implements WebMvcConfigurer{


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

如果你是使用的老的版本SpringBoot,通過繼承WebMvcConfigurationSupport來擴展SpringBoot相關的配置,則把以上配置加在相應的addResourceHandlers方法中即可

推薦使用實現(xiàn)WebMvcConfigurer接口的方式來進行擴展

如果以上方式還是不行,建議開啟Spring的Debug日志來進行跟蹤,一般訪問doc.html頁面會出現(xiàn)如下日志(成功情況下)：

同理，在使用SpringMvc或者shiro等權限框架時，如果頁面無法訪問，配置doc.html屬性即可
