Mybatis批量更新时遇到大坑.md

批量更新代码如下

id="insertMessageReply" parameterType="list">
  collection="list" close="" index="index" item="item" separator=";">
  insert into message_reply(create_time,from_username)
    values
        (
    #{item.CreateTime,jdbcType=BIGINT},
    #{item.FromUserName,jdbcType=VARCHAR},
    
    )

执行时总是报语法错误 1.Mybatis批量插入时必须在连接地址后面加?allowMultiQueries=true

2.另外还需注意分隔符必须是分号; separator=";"
