ids 存储多个用户 id，并添加 getter/setter 方法  mapper.xml collection="ids" open=" and id in(" close=")" item="id" separator="," > #{id}  测试代码： resultType="user"> select * from user collection="list" item="item" open="and id in("separator=","close=")"> #{item.id} resultType="user"> select * from user collection="array" index="index" item="item" open="and id in("separator=","close=")"> #{item.id}

当这些参数属于我们业务 POJO 时，我们直接传递 POJO 5) Map 我们也可以封装多个参数为 map，直接传递 6) Collection/Array 会被 MyBatis 封装成一个 map 传入, Collection 对应的 key 是 collection,Array 对应的 key 是 array. 如果确定是 List 集合，key 还可以是 list. collection ： 复杂类型的集 JAVAEE 课程系列 ————————————————————————————— 21 更多 Java –大数据 –前端 –python 人工智能资料下载，可访问百度：尚硅谷官网 --> 4.7.5 collection 1) POJO 中的属性可能会是一个集合对象,我们可以使用联合查询，并以级联属性的方式封 装对象.使用 collection 标签定义对象的封装规则 public class Department { private Integer id ; private

bigdecimal BigDecimal object Object map Map hashmap HashMap list List arraylist ArrayList collection Collection iterator Iterator typeHandlers 无论是 MyBatis 在预处理语句（PreparedStatement）中设置一个参数时，还是从结果集中取出一个值时， setProperties(properties); } public boolean isCollection(Class type) { return Collection.class.isAssignableFrom(type); }} <collection property="posts" ofType="Post">
