correct bug: when uploadfile with empty name; refine sprint mvc test case for imagecontroller
rename placeholder with prefix spring and using h2.driver db for testing and write basic test examples
correct hibernate.prop.. -> hibernate-test.properties
correct ImageReaderTest
modify hibernate-test.properties
modify testConvert in ImageControllerTest.java
compelete selector for option and selector for size and add test img resources
change to use ImageConvertDllLibrary.convertImage3 method
add placehoder for log.appender
