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

方法一：

建立一個spring boot demo，啓動main方法出現以下錯誤

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).

Process finished with exit code 1

緣由：因爲建立的spring boot的時候在pom.xml上引入了mybatis包的緣由，而在配置文件中沒有涉及，因此以後在pom.xml上刪除mybatis包的引入就行。

方法二：

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)

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