spring boot启动报错，数据库连接相关

Question

报错信息如下
Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

配置文件

pom文件配置如下:

Answer 1

重新搭建了一遍架构后解决了，还没查出原因，谢谢各位了

Answer 2

mysql-connector加到pom.xml里去了吗？

Answer 3

应该是你把pom文件里的tomcat给exclude了，在使用内置tomcat的时候，不要注释掉。

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <!-- 打war包部署到外部tomcat时排除内嵌Tomcat jar包-->
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>

            </exclusions>
        </dependency>

Answer 4

确实感觉像是没有数据库连接驱动，把mysql或者h2database的依赖添加到pom.xml中试一下，题主最好把pom.xml配置也贴出来一下。

Answer 5

Mysql连接驱动没有注册上，应该是找不到相应的类名，请把driver-class-name改成driverClassName，试试！

Answer 6

从Action的信息来看，你是不是配置了多环境，指定一个Profile应该就可以了。
