Access denied for user 'xxx'@'localhost' 问题的解决方法

使用SpringMvc + Mybatis + Mysql搭建的架构，调试时出现了以下错误：

HTTP Status 500 - Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: Access denied for user 'Lzj'@'localhost' (using password: YES)

网上的一些说法是数据库没有访问权限，当然这是一种情况。

起始还有另一种可能，就是框架没有拿到datasource正确的username，这个和配置有关：

我原先的applicationContext.xml文件配置是这样的：

    <!-- 加载properties -->

    <context:property-placeholder location="classpath:datasource.properties" />

    <!--  配置datasource  -->

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >

        <property name="driverClassName" value="${driverClassName}"/>

        <property name="url" value="${url}"/>

        <property name="username" value="${username}"/>

        <property name="password" value="${password}"/>

    </bean>

datasource.properties文件代码如下：

driverClassName=com.mysql.jdbc.Driver

url=jdbc:mysql://127.0.0.1:3306/test

username=root

password=test

这样框架在构造AbstractDriverBasedDataSource实例时，拿到的username始终是当前机器名。

我也没有找到构造username的代码！

最后将datasource.properties文件的username改为jdbc.username,即：

driverClassName=com.mysql.jdbc.Driver

url=jdbc:mysql://127.0.0.1:3306/test

jdbc.username=root

password=test

applicationContext.xml文件的dataSource的bean配置如下：

    <!--  配置datasource  -->

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >

        <property name="driverClassName" value="${driverClassName}"/>

        <property name="url" value="${url}"/>

        <property name="username" value="${jdbc.username}"/>

        <property name="password" value="${password}"/>

    </bean>

这样就解决了，每次都拿错username的问题。具体是什么原因，我也不知道。还需要在研读源码。

各位如有知道原因的，请留言。

后续如有答案，我会补上。
