连接oracle时报错：ORA-28001: the password has expired

调试Web项目的时候出现异常：

java.sql.SQLException: ORA-28001: the password has expired

网上查了一下，是Oracle11g密码过期的原因

连接Oracle，以Oracle用户登陆，输入以下命令

select * from dba_profiles where profile='DEFAULT' and resource_name='PASSWORD_LIFE_TIME';

结果显示：

PROFILE
------------------------------------------------------------
RESOURCE_NAME
------------------------------------------------------------
RESOURCE_TYPE
----------------
LIMIT
------------------------------------------------------------

DEFAULT
PASSWORD_LIFE_TIME
PASSWORD
180

------------------------------------------------------------

结果显示密码有效期是180天

输入命令：

alter profile default  limit password_life_time unlimited;
commit;

再次执行：

select * from dba_profiles where profile='DEFAULT' and resource_name='PASSWORD_LIFE_TIME';

结果显示为：

PROFILE
------------------------------------------------------------
RESOURCE_NAME
------------------------------------------------------------
RESOURCE_TYPE
----------------
LIMIT
------------------------------------------------------------

DEFAULT
PASSWORD_LIFE_TIME
PASSWORD
UNLIMITED
------------------------------------------------------------

进行以上步骤之后需要改变密码，否则还会出现password has expired异常

改变密码的命令

alter user XXXUSER identified by Welcome1;

如果账号被锁住，则需要解锁命令

alter user XXXUSER identified by oracle account unlock;
