Il peut y avoir plusieurs raisons ...!

  • -> Syntaxe SQL (peut-être qu'une seule petite requête a un extra, à la fin de la sélection) 

  • -> Problèmes de classpath, impossible de résoudre les dépendances de jar

  • -> Cela peut également être dû à un problème d’encodage de fichier ou à l’incorporation de caractères xml illégaux dans votre fichier '* Mapper.xml'. (alors faites attention à votre éditeur ..!)

Plus important encore, vous devriez utiliser les mêmes noms pour.

  • interface = xxx.yyy.mappers.SettingMapper.class 
  • fichier de mappeur = /xxx/yyy/mappers/SettingMapper.xml 
  • mapper namespace = xxx.yyy.mappers.SettingMapper

Bonjour, ce problème est généralement connecté à des emplacements de mappeur . Essayez donc de définir la propriété mapperLocation dans votre SqlSessionFactory bean:

<property name="mapperLocations" 
value="classpath*:pathWhereYouHaveMapper/*Mapper.xml" />

J'espère que ça aide!

Cela signifie généralement que mybatis ne peut pas trouver le mappage auquel vous faites référence. Peut-être avez-vous oublié d'ajouter le fichier * Mapper.xml à mybatis-config.xml (qui est un fichier de configuration standard pour MyBatis)

<mappers>
  <mapper resource="org/mybatis/builder/AuthorMapper.xml"/>
</mappers>

Voir plus de documentation http://mybatis.github.io/mybatis-3/configuration.html#mappers

En ajoutant aux autres réponses, vous devez également

Rechercher les noms de méthodes en double

Cette erreur vient enfin dans le journal.

IllegalArgumentException: Mapped Statements collection does not contain value

Ignorez le message ci-dessus et remontez simplement vos journaux et recherchez le premier message d'erreur dans les journaux. La première erreur que j'ai eu était, 

ERROR [main] mapper.MapperFactoryBean (MapperFactoryBean.Java:83) - Error while adding the mapper 'interface com.xyz.mappers.UserMapper' to configuration.
Java.lang.IllegalArgumentException: Mapped Statements collection already contains value for com.xyz.mappers.UserMapper.getAllUserDetails

L'erreur indique clairement que la méthode getAllUserDetails existe déjà dans l'interface UserMapper (avec un nombre différent de paramètres). La duplication des noms de méthodes lève également cette erreur. (La pénalité pour copier-coller des codes): P

Dans mon cas, ce qui s’est passé est qu’il y avait un TYPO dans mon nom de méthode dans le fichier XML de mapping . Quand j'ai changé le nom DAO, j'ai oublié de changer le xml, cela pourrait aider quelqu'un d'autre.

Vins

J'ai aussi rencontré ce problème. En plus de la possibilité de la réponse ci-dessus, j'essaie d'utiliser cette méthode qui résout le problème:

Le nom de la méthode doit être identique dans dao et mapper.xml, dans mon cas, le nom de la méthode n'est pas identique. Donc, vous devez être sûr qu'ils sont les mêmes.

Bonne chance!

Dupliqué id dans mapper.xml lève également cette exception . J'espère que cela vous aidera.

Vérifiez si vous avez mappé mybatis.config dans le fichier de propriétés. 

ajoutez cette ligne dans le fichier application.properties.

mybatis.config=classpath:mybatis-config.xml

J'utilise mybatis de la même manière que vous. Votre code a l'air bien. Même si je ne suis pas sûr s'il y a un problème avec les mappages de types. Essayez deux astuces suivantes pour résoudre votre problème:

  1. changez le type de Java en alias mybtis a) "Java.lang.Long" -> "long", b) "com.aieap.model.Comuni" -> "comuni"

  2. essayez d'ajouter un alias au lieu d'un mappage XML @ org.Apache.ibatis.type.Alias ​​("comuni") dans com.aieap.model.Comuni, supprimez xml typeAlias, ajoutez une configuration de ressort à votre org.mybatis.spring. SqlSessionFactoryBean: 

Bonne chance, Martin

Je suis tombé sur cette exception aussi. Dans mon cas, le fichier XML mappeur était présent dans un fichier JAR inclus dans le chemin d'accès aux classes, mais il n'a pas pu être trouvé par le MapperScannerConfigurer. J'ai appris cela en lisant les journaux. Vous devriez lire les journaux et vérifier la ligne du format suivant pour savoir si des mappeurs ont été trouvés. Je devais lui donner le chemin racine, après quoi il trouva mon mappeur. 

PathMatchingResourcePatternResolver:423 - Resolved location pattern [classpath*:*.xml] to resources [URL [jar:file:/home/user/src/Tomcat8/webapps/example/WEB-INF/lib/ExampleDao-1.0.0-SNAPSHOT.jar!/TestMapper.xml]]

J'ai eu le même problème. Ensuite, j'ai trouvé que toutes les demandes pour lesquelles les mappages de requêtes étaient définis sur ce fichier mapper.xml avaient la même erreur. 

Cela est peut-être dû à une construction incorrecte de WAR ou à un déploiement incorrect sur le serveur . Quoi qu'il en soit, j'ai supprimé ce fichier WAR, puis je l'ai redéployé et cela a fonctionné!
