springboot启动报错  
Failed to configure a DataSource: ‘url’ attribute is not specified and no embedde  
原因分析

DataSourceAutoConfiguration会自动加载.
    	没有配置spring - datasource - url 属性.
    	spring - datasource - url 配置的地址格式有问题.
    	配置 spring - datasource - url的文件没有加载.

解决方案：

1.@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
    2.配置application.yml/application.properties数据库信息
    3.数据库信息没有转义处理，进行转义即可
    4.yml或者properties文件没有被扫描到,需要在pom文件中<build></build>添加如下.来保证文件都能正常被扫描到并且加载成功.
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.yml</include>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.yml</include>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
