配置文件不支持空格，如：db.properties
经测试发现db.properties的选项不支持空格。
比如数据库连接
db.username=root
db.password=666666
我用
db.username= root
db.password=666666配置后无法连接到数据库
或是在db.username=root root后面多了一个空格无法连接到数据库
db.password=密码 密码的前面或是后面出现空格都无法连接到数据库
由于在=后面很容易误操作出现空格，但是现在的编辑器很难发现后面有空格，这样导致在配置的时候出现问题，因此建议对相关的配置文件在值的前面或是后面把空格去掉
db.maxActive=100 在100后面打空格也是出现报错的问题

properties文件的等号左右本来就不能有空格的吧
jdk自带的properties处理,是去掉等号两侧的空格和key前面的空格
[空格]ABC[空格]=[空格]123[空格]
得到的是 ABC=123[空格]
提交了个pull request, 考虑合并呢, 还是不合并呢...
