Answer 1

我使用的MyBatis一样你。你的代码看起来很好。即使我不确定类型映射是否存在问题。试试以下两个技巧来解决你的问题：

1. 变化的Java类型mybtis别名 一） “java.lang.Long中的” - > “长”，B） “com.aieap.model.Comuni” - > “COMUNI”

2. 尝试添加别名，而不是XML映射 @ org.apache.ibatis.type.Alias（ “COMUNI”）以com.aieap.model.Comuni，删除XML typeAlias，加弹簧配置，以您org.mybatis.spring.SqlSessionFactoryBean：

祝你好运， 马丁

Answer 2

嗨，这个问题通常是连接到映射器的位置。 所以尝试设置mapperLocation属性在bean：

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

希望它能帮助！

Answer 3

可能有几个原因......！

• - > SQL语法（也许一个小的查询有一个额外的 “” 在选择结束）

• - >类路径的问题，解决不了依赖的JAR

• - >这也可能是由于文件编码问题或非法XML文件嵌入在您的'* Mapper.xml'文件中。 （所以小心你的编辑器！！）

最重要的是你应该使用相同的名字。

• 接口= xxx.yyy.mappers.SettingMapper.class
• 映射文件= /xxx/yyy/mappers/SettingMapper.xml
• 映射器命名空间= xxx.yyy.mappers.SettingMapper

Answer 4

这通常意味着mybatis无法找到您引用的映射。也许你忘记了* Mapper.xml文件添加到的MyBatis-config.xml中（这是MyBatis的一个标准配置文件）

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

见多文档http://mybatis.github.io/mybatis-3/configuration.html#mappers

Answer 5

在我的情况下发生了什么是否在我的方法名称中映射xml文件中有一个TYPO。 当我更改了DAO名称时，我忘了在xml中进行更改，它可能会帮助其他人。

Answer 6

mapper.xml中重复的id也会引发此类异常。 希望这有助于。

Answer 7

我有类似的问题。然后我发现所有具有在mapper.xml中定义的查询映射的请求具有相同的错误。

可能是因为WAR的构建不当或者对服务器的部署不当。 无论如何，我删除了这个WAR文件，并重新部署，它的工作！

Answer 8

我也遇到过这个例外。在我的情况下，mapper xml文件出现在类路径中包含的JAR中，但不知何故，MapperScannerConfigurer找不到它。我通过阅读日志来了解这一点。您应该阅读日志并检查以下格式的行，以确定是否找到任何映射器。我不得不给它的根路径，之后它找到了我的映射器。

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]] 

Answer 9

添加到其他的答案，你还必须

Check for duplicate method names

时的误差，最后谈到在日志中。

IllegalArgumentException: Mapped Statements collection does not contain value 

忽略上面的消息，并简单地向上移动日志并查找日志中的第一条错误消息。我得到的第一个错误是，

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 

错误明确指出，该方法getAllUserDetails在UserMapper接口已经存在（有不同数量的参数）。复制方法名称也会引发此错误。 （复制粘贴代码的惩罚）：P

Answer 10

我也遇到过这个问题。除了上述答案的可能性，我尝试用这种方式解决该问题：

的方法名称应该为dao和mapper.xml一样，在我的情况的方法名称不一样。所以你必须确定它们是一样的。

祝你好运！
