APPLICATION FAILED TO START

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

原因：数据源配置未被激活

解决方案：

在启动类的注解添加如下代码即可：

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
public class SpringbootShiroApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootShiroApplication.class, args);
    }

}
