今天在写Springboot代码的时候遇到了一项错误
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled. 2022-07-02 16:28:00.656 ERROR 5844 --- [ restartedMain] o.s.b.d.LoggingFailureAnalysisReporter : *************************** 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). Disconnected from the target VM, address: '127.0.0.1:49749', transport: 'socket' Process finished with exit code 0
解决方式：
1.在在@SpringBootApplication注解后面加上(exclude ={DataSourceAutoConfiguration.class})，如图：
2.在application.yml或者application.properties中更改端口号
