写了个Demo启动项目后,操作数据库时报错errorCode 1045, state 28000。 编写测试类,数据库增删改查ok,排除账号密码,驱动等异常问题。分析数据源配置文件,之前用的是读取jdbc.properties来获取各个属性,现在配置文件里直接写。改后项目ok。经比较,问题出在一下两个地方:

 		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		
<!-- 		<property name="username" value="root" />
		<property name="password" value="root" /> -->

直接指定账号密码值,一切ok,如果通过properties获取就会报错(错误log见最后)。 jdbc.properties具体内容如下:

jdbc.driver=com.mysql.jdbc.Driver  
jdbc.url=jdbc:mysql://127.0.0.1:3306/ssm?useUnicode=true&characterEncoding=utf-8  
jdbc.username=root  
jdbc.password=root 

#pool settings
jdbc.pool.init=1
jdbc.pool.minIdle=3
jdbc.pool.maxActive=20

#jdbc.testSql=SELECT 'x'
jdbc.testSql=SELECT 'x' FROM DUAL

spring-dao.xml配置文件如下:

通过debugger源代码,发现账号密码能获取到,均为root。同时检查了下vpn和代理,均没开。
无意中看待到
Access denied for user 'root  '@'localhost' (using password: YES),发现配置文件"jdbc.username=root  "在root后面多了两个空格,删掉重启一切正常。但是不明白的是com.alibaba.druid.pool.DruidAbstractDataSource.createPhysicalConnection方法能过滤空格获取账号密码,但最后一直死循环报错。

总结下,不管druid能否过滤空格,过滤后怎么处理都要保证字段定义正确。另外网上复制代码后一定要检查。上述空格就是这样产生的。
