**问题：**

配置druid 访问地址 [http://localhost:8887/druid/index.html][http_localhost_8887_druid_index.html]

报错：This application has no explicit mapping for /error, so you are seeing this as a fallback

druid版本：

<dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>druid-spring-boot-starter</artifactId>
                <version>1.1.21</version>
            </dependency>

将druid版本降低为 1.1.10 启动项目访问[http://localhost:8887/druid/index.html 可以正常访问][http_localhost_8887_druid_index.html]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5waW5nMTk5Mw_size_16_color_FFFFFF_t_70 1][]

再次将druid版本升级为  1.1.13 访问报错 404

**问题分析**：

druid版本1.1.10以上版本配置改变。

查询资料发现，1.1.10版本以上需要配置开启 stat-view-servlet ，不配置情况下为默认不开启 监控页面，其他一些配置 如sql监控也是默认不开启的，若是要开启某个功能要手动开启，配置参考

**总结**：

若是要默认开启druid的配置，选择1.1.10及以下的版本，若是要选择手动开启某些配置，可以选择1.1.10以上的版本。
