‘url‘ attribute is not specified and no embedded datasource could be configured.

记录一次Springboot项目打包后运行出现’url’ attribute is not specified and no embedded datasource could be configured

<build>
		<resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                </includes>
            </resource>
        </resources>
</build>

然后打包jar，运行后又发现，虽然成功运行，但是访问什么页面都是

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

最后发现我的项目下的resources下放着我所有的静态文件static，但是上面代码说的<includes><include>**/*.properties</include></includes>则表示仅打包这个类型的文件，所以访问资源的时候就会出现上图这种的情况

此时我们只需要把这些静态文件打包进去

<resource>
    <directory>src/main/resources</directory>
      	<includes>
             <include>static/**</include>
             <include>**/*.properties</include>
        </includes>
</resource>
或
<resource>
    <directory>src/main/resources</directory>
</resource>
