mybtis in 查询传入参数为list

 

1 如果传入参数只有一个且类型是List， 则在使用时，collection属性要必须指定为 list

例：

mapper.java

List<TYzglKhjls> selectWxlsByZyryBh(List<String> yxlsbhList);

mapper.xml

<select >
       select c_bh, c_zyry_bh, c_zyry_dh, c_lsxm, c_zjhm, c_lxdh, n_sfyx, c_ssdw
        from {db.t_yzgl_khjls}
        where n_sfyx = 1 and c_bh not in
            <foreach collection="list"  item="item"  open="(" separator="," close=")">  
                     #{item}  
            </foreach>  
 </select>

 

 

 2，如果传入参数使用了@Param（value="value"）,collection的属性必须为"value"值

例：

mapper.java

List<TYzglKhjls> selectWxlsByZyryBh(@Param("zyrybh")String zyrybh, @Param("yxlsbhList")List<String> yxlsbhList);

mapper.xml

<select >
       select c_bh, c_zyry_bh, c_zyry_dh, c_lsxm, c_zjhm, c_lxdh, n_sfyx, c_ssdw
        from {db.t_yzgl_khjls}
        where c_zyry_bh = #{zyrybh} and n_sfyx = 1
               <if test="yxlsbhList != null and yxlsbhList.size() &gt; 0">
                and c_bh  in
                <foreach collection="yxlsbhList"  item="item"  open="(" separator="," close=")">  
                         #{item}  
                </foreach>  
            </if> 
    </select>
