Question

我正在编写一个Spring + SpringMVC + MyBatis DEMO。当我尝试连接到MySQL时，会发生以下异常：

Servlet.service() for servlet [myServlet] in context with path [/teamMAN]  threw exception [Request processing failed; 
nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; 
nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user 'TMing'@'localhost' (using password: YES))] with root cause
**java.sql.SQLException: Access denied for user 'TMing'@'localhost' (using password: YES)**

完整说明：

通过命令行“mysql -u root -p”连接到本地db没有问题。

在我的属性文件中，db username是'root'。所以我想知道为什么它试图使用'TMing'连接到db。我不知道'TMing'是什么。 'TMing'不是db uesr，也不是我的计算机名。

提前多多感谢。

我可能从这个

看到一个问题

context：property-placeholder location =＆＃34; classpath：/META-INF/properties/jdbc.properties" /＆gt;

META-INF不属于classpath。我不认为Spring正确加载你的属性。您可以通过将配置直接放在spring-mybatis.xml中来测试它。如果它有效，那么将jdbc.properties移动到类路径下的某个位置（如果是Maven，它应该在src/main/resources下）。

java.sql.SQLException：用户'TMing'@'localhost'拒绝访问（使用密码：YES）
