select字句问题
为什么我和老师一样使用了select字句我查询的时候还是查询了其他列的数据，而且是给select字句指定的列名查询了两遍。代码如下
private static void testquery4(Session session) {
String hql = "select s.name,s,tel,s.address,s.star from SellerEntity s";
Query query = session.createQuery(hql);
List<Object[]> list = query.list();
for (Object[] objs:list){
System.out.println("name:"+objs[0]);
System.out.println("tel:"+objs[1]);
System.out.println("address:"+objs[2]);
System.out.println("star:"+objs[3]);
}
}输出如下
Hibernate: select sellerenti0_.name as col_0_0_, sellerenti0_.Id as col_1_0_, sellerenti0_.tel as col_2_0_, sellerenti0_.address as col_3_0_, sellerenti0_.star as col_4_0_, sellerenti0_.Id as Id1_4_, sellerenti0_.name as name2_4_, sellerenti0_.tel as tel3_4_, sellerenti0_.address as address4_4_, sellerenti0_.website as website5_4_, sellerenti0_.star as star6_4_, sellerenti0_.business as business7_4_ from seller sellerenti0_ name:A服装店 tel:yang.entity.SellerEntity@3518e16c address:13000000000 star:中国北京××区 name:B数码店 tel:yang.entity.SellerEntity@6900a87f address:15800000000 star:中国浙江杭州市××区 name:C电器店 tel:yang.entity.SellerEntity@dac41fd3 address:13012341234 star:中国广东深圳市××区 name:D书店 tel:yang.entity.SellerEntity@1096d97d address:18600000000 star:中国陕西西安市××区
也就是按没有用select字句和加上select字句的结果都有
