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：

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。
