Spring Boot报 Action: Consider the following: If you want an embedded database (H2, HSQL or Derby)...

异常：

        Spring Boot项目启动不成功报

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).

首先检查生成的 target 文件中是否包含了你在resources 中编写的的配置文件 application.yml等等，若没有包含，而你的项目中却需要调用就会报此异常，你可以添加以下代码至pom.xml中。里面的.properties可以视你的配置文件后缀名所定。

<build> <!--idea 识别.xml 指定资源的位置--> <resources> <resource> <directory>src/main/java</directory><!--所在目录--> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> <resource> <directory>src/main/resources</directory><!--所在目录--> <includes> <include>**/*.yml</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> </resources> </build>

再者还有可能是因为spring boot 会默认加载org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration这个类，而DataSourceAutoConfiguration类使用了@Configuration注解向spring注入了dataSource bean，又因为项目（eureka-server模块和短信模块）中并没有关于dataSource相关的配置信，所以当spring创建dataSource bean时因缺少相关的信就会报错。

解决方法就是在启动类头上加行代码。

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class) public class SpringBootApplication { public static void main(String[] args) { SpringApplication.run(SpringBootApplication.class, args); } }
