SpringBoot中@Insert、@Update实现批量新增更新的使用示例

 // 批量新增
 @Insert("<script>" +
            "INSERT INTO userInfo" +
            "        (id,name,money)" +
            "        VALUES" +
            "        <foreach collection ='list' item='userInfo' separator =','>" +
            "            (#{userInfo.id}, #{userInfo.name}, #{userInfo.money})" +
            "        </foreach >" +
            "</script>")
    void insertUsers(@Param("list") List<userInfo> userInfos);

 [ 
    {  "id":4,
       "money":"102.3",
       "name":"XU"
       },
    {  "id":5,
        "money":"289.64",
       "name":"RC"
       }
        ]
