package cn.test.util;import java.lang.reflect.Method;import java.util.List;public class AutoMapper{public static <TSource,TDestination> void mapping(TSource source,TDestination destination){Method[] srcMethods = source.getClass().getMethods();Method[] destMethods = destination.getClass().getMethods();for(Method m :srcMethods){String srcMethodName = m.getName();if(srcMethodName.startsWith("get"))//调用get方法{try{   Object getValue =m.invoke(source);//获取当前方法返回值(获取当前属性值)   for(Method dm : destMethods)   {   String destMethodName  = dm.getName();//目标方法名称   if(destMethodName.startsWith("set") && destMethodName.substring(3, destMethodName.length()).equals(srcMethodName.substring(3, srcMethodName.length())))   {   dm.invoke(destination, getValue);   }   }}catch (Exception e){}}}}public static <S, T> List<T> mappingList(List<S> src, List<T> target, Class<?> targetClass){for(int i = 0; i < src.size(); i++){try{Object object = targetClass.newInstance();target.add((T) object);mapping(src.get(i), object);}catch (Exception e){continue;// 某个方法反射异常}}return target;}}

映射实体：

PersonDto p = personDtoList.get(j);  //DTOPerson personInfo = new Person(); //POJOAutoMapper.mapping(p, qInfo);//将DTO实体类的值映射到POJO上去(字段一致的才会)

映射集合：

List<Person> pList = new ArrayList<Person>(); //POJO ListAutoMapper.mappingList(q.getOptions(), pList, Person.class); //将DTO List 映射到 POJO List    options为List<PersonDto>
