Failed to determine a suitable driver class

启动就报这个谬误：

Description:Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-configured.Reason: Failed to determine a suitable driver classAction: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)

看字面意思是没找到数据源。网上说是在利用中没有用到数据源然而增加了mybatis的依赖：

<dependency>    <groupId>com.baomidou</groupId>    <artifactId>mybatis-plus-boot-starter</artifactId></dependency>

很惋惜我不是这种状况，我的这个模块是服务模块，外面用到mybatis-plus的相干包，而且application.yml文件中也配置了数据源失常：

datasource:  driver-class-name: com.mysql.cj.jdbc.Driver  username: root  password: 123456  url: jdbc:mysql://localhost:3306/seckill?serverTimezone=GMT%2B8

说什么要在启动类下面排除数据源的主动注入：

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)//去掉数据源

而后就报这个错：

Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

而后竟然让写一个根底dao：

可能是为了解决多数据源的问题吧，勾销了主动注入。没用到多数据源，不太关怀这个。

解决方案：因为咱们dao层是继承于一个dao基类，所以只有在这个基类中注入任意一个属性即可。SqlSessionFactory在spring配置文件中曾经配置。

public class CommonDao extends SqlSessionDaoSupport {     @Resource     public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory){         super.setSqlSessionFactory(sqlSessionFactory);     }}

而后我所有的mapper都要继承这个。。。

果决放弃，最终找到如下计划。

解决办法

亲测无效，在pom.xml文件增加如下：

<build>    <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></build>
