無法與春天開機連接mysql

我使用Spring啓動並要連接到MySQL數據庫無法與春天開機連接mysql

POM文件

項目結構

application.properties

spring.datasource.driver-class-name=com.mysql.jdbc.Driver 
spring.datasource.url=jdbc:mysql://localhost:3306/jinay 
spring.datasource.username=root 
spring.datasource.password= 

spring.jpa.database = MYSQL 
spring.jpa.show-sql = true

在啓動時它提供了以下異常

org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. 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).

我不知道是什麼，似乎是錯誤的。試圖谷歌搜索，但沒有找到任何可行的。

任何幫助非常感謝！

你可以嘗試連接到本地（即使用松鼠或任何其他rool）？另外，你能否檢查一下數據庫是否是MySQL而不是Mariadb或其他變體？ –

@DarshanMehta這是MySql，我可以使用Mysql工作臺連接它，並可以在該實例中訪問模式和表。我不知道有任何其他工具在本地連接它。沒有使用Squirrel –

能否請您檢查是否有MySQL驅動程序相關加入pom.xml，如：

<dependency> 
    <groupId>mysql</groupId> 
    <artifactId>mysql-connector-java</artifactId> 
    <version>5.1.6</version> 
</dependency>

此外，您可能要包括envers depedencies春數據和休眠：

<dependency> 
    <groupId>org.springframework.data</groupId> 
    <artifactId>spring-data-envers</artifactId> 
    <versoion>some version</version> 
</dependency> 

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-envers</artifactId> 
    <versoion>some version</version> 
</dependency>

mysql依賴已經是pom.xml的一部分。添加額外的envers依賴關係，但錯誤仍然存在:( –

你可以嘗試設置一個非空密碼（通過在db中創建一個測試用戶）？ –

定義你的網址如下。我有一個工作的例子，如果我定義我的網址如下。

spring.datasource.url=jdbc:mysql://localhost/testdb

此錯誤是，如果春天開機無法讀取您的application.properties文件，你會想到什麼。確保您的IDE（Eclipse）確實構建了您的項目，並確保應用程序屬性位於類路徑中。

我注意到的另一件事是，你沒有使用spring-boot-maven-plugin。即使你正在構建一個.WAR文件，你也應該使用這個插件，這很可能會導致你的.WAR文件的構建方式不同。

<plugin> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-maven-plugin</artifactId> 
</plugin>
