【问题描述】:
我正在尝试在 tomcat 8.0 中应用程序,但出现错误
org.springframework.jdbc.CannotGetJdbcConnectionException: 无法获得 JDBC 连接;嵌套异常是 java.sql.SQLException: No suitable driver found for jdbc:mysql://ip:3306/DURGA_DEV?characterEncoding=UTF-8

我正在使用
- Tomcat 8.0.21
- 春季 4.1.6
- Mysql 连接器:mysql-connector-java-5.1.27.jar
我的 context.xml 文件如下所示。

【问题讨论】:
-
您能否包含此数据源的 context.xml sn-p 以及您尝试打开数据库连接的代码
-
@jay 我已经附加了 context.xml 和 datasource 属性。如果我降级 tomcat 7.0.6 和 Spring 3.2,我的应用程序可以正常工作
-
我将开始消除查看错误所在的可能性。 1)你可以从运行tomcat的服务器连接吗?尝试在 java 应用程序之外手动连接。 2)是否正确读取了属性文件?尝试在 context.xml 中硬编码连接值。 3)tomcat是否尝试连接?检查数据库日志。等等……
