Question

我在tomcat 8.0中尝试应用程序，但是我收到了错误

org.springframework.jdbc.CannotGetJdbcConnectionException：无法获取JDBC连接;嵌套异常是java.sql.SQLException：没有为jdbc找到合适的驱动程序：mysql：// ip：3306 / DURGA_DEV？characterEncoding = UTF-8

我正在使用

Tomcat 8.0.21
Spring 4.1.6
Mysql Conector：mysql-connector-java-5.1.27.jar

我的context.xml文件如下所示。

Answer 1

这意味着您的mysql驱动程序jar不在类路径中。确保它在“$ CATALINA_HOME / lib”

中

Answer 2

在部署我的应用程序并从Eclipse启动Tomcat时，我遇到了类似的问题。在构建战争并将其手动复制到webapps文件夹后，它正在运行。

我的设置与此问题中描述的非常相似：

java.sql.SQLException: No suitable driver

Driver类位于Tomcat的lib文件夹中，但看起来，从Eclipse部署到wtpwebapps时，我的config.xml未加载。

找不到适合于jdbc的驱动程序：来自tomcat 8.0的mysql
