由将SQL查询结果转化为pojo的想到的
今天在网上上看见一篇“将SQL查询结果转化为pojo对象的”博客，博主自定义做了一个类如下：
import java.lang.reflect.Field;
import java.util.List;
import org.hibernate.HibernateException;
import org.hibernate.property.ChainedPropertyAccessor;
import org.hibernate.property.PropertyAccessor;
import org.hibernate.property.PropertyAccessorFactory;
import org.hibernate.property.Setter;
import org.hibernate.transform.ResultTransformer;
/**
* 完成native sql查询数据（数组）到pojo对象的转化

public class PojoTransformer implements ResultTransformer {
private static final long serialVersionUID = 1L;
private Class<? extends BaseModel> resultClass;
private Setter[] setters;
private PropertyAccessor propertyAccessor;
public PojoTransformer(Class<? extends BaseModel> resultClass) {
if(resultClass==null)
throw new IllegalArgumentException("resultClass cannot be null");
this.resultClass = resultClass;
propertyAccessor = new ChainedPropertyAccessor(new PropertyAccessor[] { PropertyAccessorFactory.getPropertyAccessor(resultClass,null), PropertyAccessorFactory.getPropertyAccessor("field")});
}
//结果转换时，HIBERNATE调用此方法

在网上看到SQL字符串转16进制的语句，经过小小添加，现将SQL字符串与16进制互换的方法记录，以供以后查看。
--SQL char->HEX code
