I have recently came up with a deployment Exception of my web application (after receiving some changes from the SVN Repository) that said:
我最近提出了我的 Web 应用程序的部署异常（在收到来自 SVN 存储库的一些更改后），它说：
< Error > < Deployer > with ID '1350377960779' for task '1'.

Googling to find an answer was not very helpful. After examining the files received from my SVN repository, i noticed that a jdbc application resource was changed.
谷歌搜索找到答案并不是很有帮助。检查从我的 SVN 存储库收到的文件后，我注意到 jdbc 应用程序资源已更改。
Examining the jdbc resource more closely i found that it was using the password-encryptedproperty which is used only for production environments
更仔细地检查 jdbc 资源，我发现它正在使用password-encrypted仅用于生产环境的属性
<password-encrypted>{AES}some+very+long+encrypted+string</password-encrypted>
So I commented out this property and used the property used for the development environment:
所以我注释掉了这个属性，使用了开发环境使用的属性：
<properties>
<property>
<name>user</name>
<value>MY_USER</value>
</property>
<property>
<name>password</name>
<value>MY_PASS_IN_PLAIN_TEXT</value>
</property>
</properties>
And that worked just fine.
这工作得很好。

I just had this problem, and all I had to do was save the page on the Connection Pool page while the password was blank. Of course then it would fail. Then put in the password and save again. This time no Pad byte error and it conencts without fail.
我刚刚遇到了这个问题，我所要做的就是在密码为空时将页面保存在连接池页面上。当然，那它会失败。然后输入密码并再次保存。这次没有Pad字节错误并且它没有失败地连接。

I clicked MaVRoSCy own response as usefull, because it works. But the downside it's that your password became visible (might not be a problem at development env).
我点击了 MaVRoSCy 自己的响应，认为它很有用，因为它有效。但缺点是您的密码变得可见（在开发环境中可能不是问题）。
This problem with password encryption can be overcome by reencrypting your password at your weblogic instance.
密码加密的这个问题可以通过在您的 weblogic 实例上重新加密您的密码来克服。
To do so, go to your weblogic domain, ex: ORACLE_HOME\user_projects\domains\YOUR_DOMAIN
为此，请转到您的 weblogic 域，例如：ORACLE_HOME\user_projects\domains\YOUR_DOMAIN
And execute this command: java weblogic.security.Encrypt YOUR_PASSWORD
并执行此命令： java weblogic.security.Encrypt YOUR_PASSWORD
This will output something like: {AES}0gcupcB95gtlr6VYnT3TZK5PxiATDuIUe3kRKd3b/Ag=
这将输出如下内容： {AES}0gcupcB95gtlr6VYnT3TZK5PxiATDuIUe3kRKd3b/Ag=
This is your encrypted password for your weblogic instance.
这是您的 weblogic 实例的加密密码。
Then just replace it at your password-encryptedproperty inside datasource xml configuration.
然后只需在数据源 xml 配置中的密码加密属性中替换它。
<password-encrypted>{AES}0gcupcB95gtlr6VYnT3TZK5PxiATDuIUe3kRKd3b/Ag=</password-encrypted>
