mybatis---遍历map做参数

Map<String, Object> ret = new HashMap<String, Object>();
ret.put("jcContent", jcContent);
ret.put("todadyTime", todadyTime);
ret.put("nextTime", nextTime);

<insert id="addJctx" parameterType="Map">
		insert into examine
		<foreach item="item" index="key" collection="paramsMap.keySet()" separator="," open="(" close=")">
  			${item}
		</foreach>
		values
		<foreach item="item" index="value" collection="paramsMap.entrySet()" separator="," open="(" close=")">
  			#{item}
		</foreach>
</insert>

二：

Map<String, Object> maps = new HashMap<String, Object>();
maps.put("patid", patid);
maps.put("txrq", time);
maps.put("tqtz", weight);

<insert id="yyy" parameterType="Map">
		insert into xxx
		<foreach collection="maps.keys" item="key" open="(" close=")" separator="," >  
            ${
    
    key}  
         </foreach>  
         values   
         <foreach collection="maps.keys"  item="key" open="(" close=")" separator=",">  
            #{
    
    maps[${
    
    key}]}  
         </foreach> 
</insert>
