使用String.split() 方法: 在MyBatis 的映射文件中,可以使用 <foreach> 标签结合 String.split() 方法来实现字符串分割。例如,假设有一个字符串 names,其中包含多个名字,用逗号分隔,可以这样实现分割: <foreach item="name" index="index" collection="list" open="(" separator="," close=")"> #{name}...
方式一:传参ids是用逗号隔开 1 2 3 4 5 6 7 8 9 10 Mapper.java List<> selectByIds(@Param("ids") String ids); Mapper.xml select * from table a where a.id in <foreach item="item"index="index"collection="ids.split(',')" open="("separator=","close=")"> #{item} </foreac...
2.通过myBatis自带功能foreach,直接把逗号分隔的字符串传到mapper.xml即可,后台不用过多操作。 select * from table where ids in <foreach item="item" index="index" collection="ids.split(’,’)" open="(" separator="," close=")"> #{item} </foreach> 注:ids就是传入的参数名称,如果报错请...
if(StringUtils.isNotBlank(ids)){ String[] temp = ids.split(","); for(int i=0;i listIds.add(Integer.valueOf(temp[i])); } } //按照城市查询 if(StringUtils.isNotBlank(cities)){ String[] temp = cities.split(","); for(int i=0;i listCities.add(temp[i]); } } Listlist = jo...
</foreach> 上述collection的值为ids,是传入的参数Map的key,对应的Mapper代码: public List<Blog> dynamicForeach3Test(Map<String, Object> params); 对应测试代码: @Test public void dynamicForeach3Test() { SqlSession session = Util.getSqlSessionFactory().openSession(); BlogMapper ...
String[] temp = ids.split(","); for(int i=0;i listIds.add(Integer.valueOf(temp[i])); } } //按照城市查询 if(StringUtils.isNotBlank(cities)){ String[] temp = cities.split(","); for(int i=0;i listCities.add(temp[i]); ...

String ids = "1,2,3,4,5,6",如ids作为参数传递,查询list返回。mybatis用foreach处理并返回。 SELECT * FROM yp_popup_store_info store WHERE store.store_id in <foreach item="item" index="index" collection="ids.split(',')" open="(" separator="," close=")"> ...
