javax.net.ssl.SSLKeyException: RSA premaster secret error

错误代码

调用api的时候控制台一直报这个错误

网上查了很多，大部分说是把jre里面的lib/ext/sunjce_provider.jar放入项目中就可以了，
但是我一直没有成功，，

后来才发现，原来是我java环境错了（尴尬），打开环境，重新配一下，运行果然没问题了。

这个问题不禁让我想到我之前的一个很蠢的错误（浪费了大半天的调试）

控制台报错

程序在本机运行都是正常的，发布到服务器上之后运行就报如下的错误

警告: com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@4b76c591 -- Acquisition Attempt Failed!!! Clearing pending acquires.

后来查出的原因让我吐血

url=
username=root
password=root

  <property name="url" value="${url}" />    <property name="username" value="${username}" />    <property name="password" value="${password}" />

发布到unix服务器上因为 value=”${username} 读取了系统主账户，后来改成 jdbc.baidu.username 就没有问题了。
