import com.beetl.performance.lab.User;
public class UserAsmAccessor implements Access {
public Object get(Object o,int index) throws ASMCastException{
User user = null;
try{
user = (User)o;
}catch(Exception ex){
throw new ASMCastException();
}
switch(index){
case 1:return user.getName();
case 2:return user.getId();
}
throw new RuntimeException();
}
}
在模板里${user.name} ,将user对应到UserAsmAccessor ,name对应到index=1，这样获取对象属性，将达到极限性能
