Not configuration problems, so that the printing is correct, because you is a bean object, receives is the screenshots of the Country, and now you can use in the Country to display attribute values, (can understand so, the Country is a data table, do you want to see the inside of the property, have to the Country. The cname, Country. The mids so take), if any problem, can focus on individual "andyqian" public, would be happy to answer for you,
