SpringBoot訪問(wèn)doc.html頁(yè)面404

默認(rèn)情況下并不需要添加此配置即可訪問(wèn)

很多朋友在使用SpringBoot集成swagger-bootstrap-ui后，都無(wú)法訪問(wèn)doc.html界面，此時(shí)，你可能需要實(shí)現(xiàn)SpringBoot的WebMvcConfigurer接口，添加相關(guān)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(guò)繼承WebMvcConfigurationSupport來(lái)擴(kuò)展SpringBoot相關(guān)的配置,則把以上配置加在相應(yīng)的addResourceHandlers方法中即可

推薦使用實(shí)現(xiàn)WebMvcConfigurer接口的方式來(lái)進(jìn)行擴(kuò)展

如果以上方式還是不行,建議開(kāi)啟Spring的Debug日志來(lái)進(jìn)行跟蹤,一般訪問(wèn)doc.html頁(yè)面會(huì)出現(xiàn)如下日志(成功情況下)：

同理，在使用SpringMvc或者shiro等權(quán)限框架時(shí)，如果頁(yè)面無(wú)法訪問(wèn)，配置doc.html屬性即可

關(guān)于SpringBoot的代碼示例可參考swagger-bootstrap-ui-demo
