各种jar包是否加入

[kangbo818]

数据库也打开了，我装得什么客户端数据库，是不是不行啊？？？

[kangbo818]

jar包肯定加了，不是jar包的问题

[fangpengyu]

知道了，数据库的用户名和密码错了，Caused by: java.sql.SQLException: Access denied for user '1'@'localhost' (using password: YES)

[kangbo818]

配置对吗？mysql是数据库名
就是use mysql；进去得

[yztommyhc]

username或者password不对吧

[kangbo818]

那配置得时候我写的就是用户名和密码都是1啊，那怎么能找到这个用户名密码？

[kangbo818]

我也感觉是那个不对，但我配置时设得那个啊，怎么办，愁

[yztommyhc]

用这个配置文件中的账号和密码应该不能登陆mysql数据库吧。

[yztommyhc]

这个就该查mysql的资料了，和java\hibernate就没什么关系了。

[kangbo818]

刚试了下，我登陆数据库时，密码是1，没错啊

[farfromcross]

数据库没有连接上吧，用户名和密码正确吗？

[kangbo818]

我找找看有没公用用户名密码

[kangbo818]

真愁啊，用户名密码就是用那个啊，都是1，为什么连不上呢，高手快来看看啊
