java.sql.SQLException：访问拒绝用户'TMing'@'localhost'（使用密码：是）

我正在编写一个Spring + SpringMVC + MyBatis DEMO。当我尝试连接到MySQL，异常如下情况发生：java.sql.SQLException：访问拒绝用户'TMing'@'localhost'（使用密码：是）

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)**

通过命令行“mysql -u root -p”连接到本地数据库没有问题。

在我的属性文件中，db用户名是'root'。所以我想知道为什么它试图使用'TMing'连接到数据库。我不知道'TMing'是什么。 'TMing'不是数据库，既不是我的电脑名称。

非常感谢。

我将$ {username}更改为另一个名称，例如$ {user}也解决了我的问题。 – Luffy

一个问题，我看到也许从这个

上下文：属性占位符位置= “类路径：/META-INF/properties/jdbc.properties”/>

META-INF没有按不属于classpath。我不认为Spring会正确加载你的属性。您可以通过将配置直接放入spring-mybatis.xml中进行测试。如果它工作，然后将您的jdbc.properties移动到您的类路径下的某个位置（如果Maven，它应该在src/main/resources之下）。

它的工作原理。非常感谢。 :) – Luffy
