Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

最终发现问题出在了没有将配置文件扫描进去，我把它排除了，我的pom.xml中资源的配置如下：

<resources>
    <resource>
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.yml</include>
            <include>**/*.properties</include>
            <include>**/*.xml</include>
        </includes>
        <filtering>false</filtering>
    </resource>
    <resource>
        <directory>${basedir}/src/main/resources</directory>
        <excludes>
                <!-- <exclude>*.properties</exclude> -->
                 <!-- <exclude>application-dev.properties</exclude>  -->
            </excludes>
        <includes>
            <include>**/*.yml</include>
            <include>application.properties</include>
            <include>application-${profile.active}.properties</include>
            <include>**/*.xml</include>
        </includes>
        <filtering>false</filtering>
    </resource>
</resources>

问题出在上面注释掉的exclude的配置上，这里理解过滤不正确，我把它排除在外了,参考https://blog.csdn.net/u014756827/article/details/52510899

<include>与<exclude>是用来圈定和排除某一文件目录下的文件是否是工程资源的。如果<include>与<exclude>划定的范围存在冲突时，以<exclude>划定的范围为准。大多数情况下，人们使用<include>和<exclude>是为了配合<filtering>实现过滤特定文件的需要。例如，在一个工程中，src/main/resources目录下都是工程的资源文件，并不需要<include>和<exclude>再进行划定。但如果我们需要对且仅对其中的jdbc.properties和mail.properties两个文件进行过滤的话，则需要借助<include>和<exclude>进行如下的配置：

    <resources>
        <!-- Filter jdbc.properties & mail.properties. NOTE: We don't filter applicationContext-infrastructure.xml, 
            let it go with spring's resource process mechanism. -->
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <includes>
                <include>jdbc.properties</include>
                <include>mail.properties</include>
            </includes>
        </resource>
        <!-- Include other files as resources files. -->
        <resource>
            <directory>src/main/resources</directory>
            <filtering>false</filtering>
            <excludes>
                <exclude>jdbc.properties</exclude>
                <exclude>mail.properties</exclude>
            </excludes>
        </resource>
    </resources>

其中第一段<resource>配置声明：在src/main/resources目录下，仅jdbc.properties和mail.properties两个文件是资源文件，然后，这两个文件需要被过滤。而第二段<resource>配置声明：同样在src/main/resources目录下，除jdbc.properties和mail.properties两个文件外的其他文件也是资源文件，但是它们不会被过滤。

注释掉以后，可以加载属性文件，就可以启动了
