SpringBoot數據庫嵌入式數據庫驅動程序異常JAVA

Question

我有這個例外，當我嘗試啓動我的彈簧引導應用程序。我已經添加了mysql-connector-java和spring-boot-starter-jdbc依賴關係，並且不知道什麼不起作用。

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). 

編輯1 這是我Maven的配置文件。

EDIT 2 這這裏是數據源配置

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()); 
    } 

} 

Answer 1

它看起來像你缺少你的DatasourceConfig.java文件@Configuration註解。

我試着用註釋和mvn spring-boot:run啓動罰款。如果沒有註解，我得到你曾表示，隨後由一個巨大的堆棧跟蹤文本：

應用程序未能啓動> [818分之26]

說明：

不能確定嵌入式數據庫驅動程序數據庫類型爲NONE的類

操作：

如果你想要一個嵌入式數據庫，請在classpath中放一個支持的數據庫。如果您的數據庫設置要從特定配置文件加載，您可能需要$ d才能激活它（沒有配置文件當前處於活動狀態）。

這裏是我的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()); 
    } 

} 

該應用程序也將啓動，無需@Configuration，如果你添加一個依賴於已知嵌入式數據庫一樣hsqldb：

<dependencies> 
    <dependency> 
     <groupId>org.hsqldb</groupId> 
     <artifactId>hsqldb</artifactId> 
     <scope>runtime</scope> 
    </dependency> 
    ... 
</dependencies>
