Mybatis非配置原因，導(dǎo)致SqlSession was not registered for synchronization異常

 更新時(shí)間：2021年04月01日 15:39:40   投稿：lqh  
本文主要介紹Mybatis非配置原因出錯(cuò),這里對(duì)這個(gè)出現(xiàn)的問(wèn)題做了詳細(xì)介紹，及解決辦法，有興趣的小伙伴可以參考下

今天運(yùn)行程序時(shí)報(bào)了

SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@69d4fb43] was not registered for synchronization because synchronization is not active

[11:03:17]-Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@69d4fb43]

由于異常是集中處理的，所以報(bào)了這樣的錯(cuò)誤，查了半天，網(wǎng)上結(jié)果都是說(shuō)配置文件出錯(cuò)的，可是我的項(xiàng)目配置文件肯定是沒(méi)錯(cuò)的，因?yàn)轫?xiàng)目都開(kāi)發(fā)了好長(zhǎng)時(shí)間了，只是我今天寫(xiě)了個(gè)方法才報(bào)的這個(gè)錯(cuò)誤，所以排除配置文件出錯(cuò)，可是我寫(xiě)的方法應(yīng)該沒(méi)問(wèn)題的，以前也這樣寫(xiě)的呀。

      網(wǎng)上查半天沒(méi)找到原因，沒(méi)辦法，只能看看自己的程序了，把自己寫(xiě)的方法異常直接打印出來(lái)，先不集中處理，然后異常出來(lái)了：

根據(jù)這個(gè)異常再查程序，發(fā)現(xiàn)問(wèn)題出現(xiàn)在departid這個(gè)參數(shù)，再查源程序，發(fā)現(xiàn)原來(lái)我寫(xiě)的那個(gè)方法的sql在mapper.xml文件里引用了對(duì)參數(shù)departid進(jìn)行判斷是否為null或空，所以才報(bào) There is no getter for property named ‘departid‘ in ‘class java.lang.String‘異常。

解決方法：一、在方法傳參時(shí)，加param參數(shù)標(biāo)識(shí)，如：countNum(@Param("departid")String departid);

                  二、在方法傳參時(shí)，把參數(shù)換成map或?qū)ο蟆?/strong>
