Spring Boot启动失败：DataSource配置错误及解决方法

2023-07-14 10:27:52.272 ERROR 47640 --- [ restartedMain] o.s.b.d.LoggingFailureAnalysisReporter  : \nAPPLICATION FAILED TO START\n\n\nDescription:\n\nFailed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.\n\nReason: Failed to determine a suitable driver class\n\n\nAction:\n\nConsider the following:\n If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.\n If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).\n\n\n If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).\n\n错误。为什么出现，该怎么解决，请用浅显易懂的话语详细说明。我使用的mysql数据库，如何添加该依赖。\n\t\t\n\t mysql\n\t mysql-connector-java\n\t \n\t \n\t org.mybatis.spring.boot\n\t mybatis-spring-boot-starter\n\t 2.0.1\n\t \n\t \n\t org.springframework.boot\n\t spring-boot-starter-data-jpa\n\t 这写的对嘛内容：根据错误信息，出现了配置数据源的错误。错误原因是未指定"url"属性并且没有配置嵌入式数据源。\n\n解决方法是：\n1. 如果你想使用嵌入式数据库（如H2、HSQL或Derby），请将其添加到类路径中。\n2. 如果你有特定配置文件需要加载数据库设置，可能需要激活该配置文件（当前没有激活的配置文件）。\n\n针对你使用的MySQL数据库，你需要添加以下依赖：\n\n<dependency>\n <groupId>mysql</groupId>\n <artifactId>mysql-connector-java</artifactId>\n</dependency>\n<dependency>\n <groupId>org.mybatis.spring.boot</groupId>\n <artifactId>mybatis-spring-boot-starter</artifactId>\n <version>2.0.1</version>\n</dependency>\n<dependency>\n <groupId>org.springframework.boot</groupId>\n <artifactId>spring-boot-starter-data-jpa</artifactId>\n</dependency>\n\n\n请确保以上依赖已正确添加到你的项目的pom.xml文件中。
