CRS->DirectEpsgFactory
To hook this up make sure you have one of the gt-epsg plugins on your CLASSPATH. The gt-epsg-hsql plugin is recommended.
DirectEpsgFactory在package org.geotools.referencing.factory.epsg;包下，
然后getConnection就发动了。。
然后就找到了DriverManager了。。
然后就报错了。。
奇怪，如果不安装postgresql，难道就不能用setCRS了吗？
