mybatis 遍历字段和字段对应的值循环插入

java代码：

/**
* 插入单条数据
* @param request
* @param response
* @param id
* @param str
* @return
* @throws Exception
*/
@RequestMapping(value="insertData")
@ResponseBody
public Map<String,Object> insertData(HttpServletRequest request,
HttpServletResponse response,Integer id,String str) throws Exception{

String tableName=null;
BusinessDesc businessDesc = businessDescService.queryById(id);
//取出所有字段
List<ColumnRule> columnnlist = columnRuleService.findByBusinessId(id);
List<Map<String,Object>> list = new ArrayList<Map<String,Object>>();
List<String> list2 = new ArrayList<String>();
Map<String,Object> maps=new HashMap<String,Object>();
JSONObject jsonObject = new JSONObject(str);
Iterator iterator = jsonObject.keys();
while(iterator.hasNext()){
Map<String,Object> map=new HashMap<String,Object>();
key = (String) iterator.next();
value = jsonObject.getString(key);
for(ColumnRule rule:columnnlist){
if(rule.getName().equals(key)){

if(value!=null && !"".equals(value)){

隐射文件：

<insert id="insertData" parameterType="java.util.Map">
insert into ${table}
(<foreach collection="list" item="item" index="index" separator=",">${item.key}</foreach>)
values
(
<foreach collection="list" item="subitem" index="index" separator=",">
#{subitem.value}
</foreach>
)
</insert>
<update id="updateData" parameterType="java.util.Map">

update
${table}
set
<foreach collection="list" item="item" index="index" separator=",">${item.key}=#{item.value}</foreach>
where id=#{id}
</update>

遍历list

dao类：List<Garage> findRecommendGarageById(List<String> list);

xml隐射文件：

<select id="findRecommendGarageById" resultMap="BaseResultMap" resultType="java.util.List">
select <include refid="Base_Column_List" /> from s_garage
<where>
id in
<foreach collection="list" index="index" item="item" open="(" separator="," close=")">
#{item}
</foreach>
</where>
</select>
