Description

I'm trying to declare mappers in some common way.

1. I have declared one common mapper interface to inherit it methods for other mappers:
interface AbstractMapper<T> {
T find(long id);
void update(T t);
void insert(T t);
}

2. Then I have declared child interface:
interfcae UserMapper extends AbstractMapper<User> {
void traceLoginEventIntoLogTable(User u);
//rest of methods should me inherited from AbstractMapper interface. I think so.
}

3. But when I run this code I had exception for statement:
SqlSession.getMapper(UserMapper.class).find(1L);
Exception was something like this:
Exception in thread "main" java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for demo.AbstractMapper.find
at org.apache.ibatis.mapping.Configuration$StrictMap.get(Configuration.java:365)
at org.apache.ibatis.mapping.Configuration.getMappedStatement(Configuration.java:311)
at org.apache.ibatis.binding.MapperMethod.determineCommandType(MapperMethod.java:79)
at org.apache.ibatis.binding.MapperMethod.<init>(MapperMethod.java:33)
at org.apache.ibatis.binding.MapperProxy.invoke(MapperProxy.java:16)
at $Proxy1.find(Unknown Source)
at ibatisdemo.Main.main(Main.java:46)

4. I think it's because method find is declared in "demo.AbstractMapper",
but I have expected to use "demo.UserMapping.find" mapping.

If full demo is needed I can find and attach it in mean time.
