今天重新创建springBoot项目的启动的时候提示：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
    2020-09-10 13:53:04.021 ERROR 9228 --- [           main] 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).

修改方法

第一种：

因为我的项目只是测试，暂时不用连接到数据库。所以需要将pom.xml中的关于连接数据的配置移除：

<dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            
                
                
                
            
    
            
                
                
                
            
        </dependencies>

然后重新加载，就没问题了。

第二种：

如果需要连接到数据库进行操作，pom文件不用修改

<dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.mybatis.spring.boot</groupId>
                <artifactId>mybatis-spring-boot-starter</artifactId>
                <version>2.1.3</version>
            </dependency>
    
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <scope>runtime</scope>
            </dependency>
        </dependencies>

需要在application.properties配置文件中添加对应的数据库的连接

#配置数据源
    spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
    spring.datasource.url=*
    spring.datasource.username=*
    spring.datasource.password=*

在重新启动即可
