当我尝试启动弹簧启动应用程序时,我遇到此异常。我添加了mysql-connector-java和spring-boot-starter-jdbc依赖项,并且不知道什么不起作用。
docker exec -it <redis container ID> redis-cli
编辑1 这是我的maven配置文件。
Description:
Cannot determine embedded database driver class for database type NONE
Action:
If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).
编辑2 这是数据源配置

答案 0 :(得分:0)
您似乎错过了@Configuration
文件上的DatasourceConfig.java
注释。
我尝试使用注释,mvn spring-boot:run
启动正常。如果没有注释,我会得到您指示的文本,然后是一个巨大的堆栈跟踪:
应用程序未能启动&gt; [818分之26]
说明
无法确定数据库类型为NONE的嵌入式数据库驱动程序类
动作:
如果您需要嵌入式数据库,请在类路径中放置一个受支持的数据库。如果您要从特定的配置文件加载数据库设置,则可以使用ne $ d激活它(当前没有配置文件激活)。
这是我的my/DatasourceConfig.java
:
package my.config;
import org.apache.commons.dbcp.BasicDataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.core.JdbcTemplate;
import javax.sql.DataSource;
@Configuration
public class DatasourceConfig {
@Bean
public DataSource getDataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/hcharts");
dataSource.setUsername("root");
dataSource.setPassword("root");
return dataSource;
}
@Bean
public JdbcTemplate jdbcTemplate() {
return new JdbcTemplate(getDataSource());
}
}
如果您向@Configuration
这样的已知嵌入式数据库添加依赖项,则应用程序也将在没有hsqldb
的情况下启动:
<dependencies>
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>runtime</scope>
</dependency>
...
</dependencies>
