What about the rest? Such as getBoolean 、 getShort、getInt、getLong？

[xingfudeshi]

GetConfig converts the values of all configuration items to strings and returns them. Other methods, such as getShort, do not require such a transformation. And Boolean cannot be cast to String.

[slievrly]

check disableGlobalTransaction and other type configuration item result is ok.
