Answer 1

The complete stacktrace shows:

Caused by: java.lang.NoSuchMethodError: org.springframework.beans.BeanUtils.findPropertyForMethod(Ljava/lang/reflect/Method;Ljava/lang/Class;)Ljava/beans/PropertyDescriptor;

This issue is caused by the Spring core version used (4.1.1), which has only one parameter for type Method (check here ).

There is dependencies mismatch, try to change Spring version to 4.1.3 or greater.
