现象：启动报错

问题排查与处理：

1：根据错误翻译，是datasource没有一些配置属性。不过检查下来写法没有啥问题

2：注意启动端口是不是生效了。发现是配置文件没起作用

3：maven添加resources

<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>**/*.*</include>
                </includes>
            </resource>
        </resources>
