注解批量修改、新增

批量修改：

1.手动添加批量删除方法

/**
 * 批量逻辑删除
 *
 * @param commentsList
 * @return
 */
@Update({
        "<script>",
        "<foreach collection='commentsList' item='item' index='index' separator=';'>",
        "UPDATE t_task_audit SET ",
        "delete_flag=1",
        "WHERE task_id=#{item.taskId}",
        "</foreach>",
        "</script>"
})
int updateBatch(@Param("commentsList") List<CommentsObject> commentsList);

2.使用注解@TableLogic,配合yml配置文件使用mybatis-plus自带的删除方法

// 删除标识
@TableLogic
private String deleteFlag;

mybatis-plus:
  global-config:
    db-config:
      logic-delete-value: 1
      logic-not-delete-value: 0

调用mybatis-plus删除方法，效果就是逻辑删除

 组装idList,批量删除
List<String> idList = new ArrayList<>();
for (CommentsObject comments : commentsList) {
    idList.add(comments.getId());
}
//批量逻辑删除审批记录
int count = commentsObjectMapper.deleteBatchIds(idList);
logger.info("批量删除主表" + record.getTaskId() + "相关的表记录" + count + "条");
