mybatis傳遞陣列資料---本人瞭解兩種

第一種：直接傳遞陣列資料

mapper中的配置：

<delete id="deleteBrandByIdsArray" parameterType="Integer[]">
	delete from bbs_brand
	<where>
		id
		<foreach  collection="array" item="id" open="in (" close=")" separator=","> 
			#{id}
		</foreach>
	</where>
</delete>
 

service中的配置：

public void deleteBrandById(Integer[] ids) {
		brandMapper.deleteBrandByIdsArray(ids);
	}

第二種：將陣列放在map中傳遞：

mapper中的配置：

<delete id="deleteBrandByIds" parameterType="java.util.Map">
		delete from bbs_brand
		<where>
			id
			<foreach  collection="ids" item="id" open="in (" close=")" separator=","> 
				#{id}
			</foreach>
		</where>
	</delete>
 

service中的配置

public void deleteBrandById(Integer[] ids) {
		Map<String, Object> params = new HashMap<String, Object>();
		params.put("ids", ids);
		params.put("params", params);
		brandMapper.deleteBrandByIds(params);
	}
