 使用 maven 玩个小项目,有spring-ds.xml 配置文件内容如下

 问题原因:

mysql-connector-java 的版本过高

<dependency>
       <groupId>mysql</groupId>
       <artifactId>mysql-connector-java</artifactId>
       <version>5.1.30</version>
</dependency>

 修改后

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
        <version>5.1.25</version>
</dependency>
