多mapper注入时，该项目会报BeanCurrentlyInCreationException，Is there an unresolvable circular reference?警告

[leimbag]

hi，abel533，我下载了本demo项目，在使用单个mapper时没有报这个警告错误，但是当把mapper增加为2个以上时，就会报该异常信息，不知具体的原因。

跟踪代码，看到会优先执行MyBatisMapperScannerConfig扫描，虽然设置了AutoConfigureAfter，MyBatisMapperScannerConfig修改definition.setBeanClass(MapperFactoryBean.class)后，spring在做dataSourceInitializerPostProcessor处理时，会抛出该异常，不知道哪里出了问题。而且会重复出现2，3边同样的WARN，百分百重现。

WARN 43180 --- [ main] o.s.b.f.s.DefaultListableBeanFactory : Bean creation exception on FactoryBean type check: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'subCountryMapper' defined in file [/tt/fsm/target/classes/com/lmtest/fsm/mapper/SubCountryMapper.class]: Cannot resolve reference to bean 'sqlSessionFactory' while setting bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'sqlSessionFactory': Requested bean is currently in creation: Is there an unresolvable circular reference?

[abel533]

包含两个吗？我测试过两个没问题。。

[leimbag]

包含2个，我是在原基础上增加了一个实体类，一个mapper和一个mapper.xml文件，就会出现上述问题，增加方式有不一样的地方吗？或者是否能提供该项目为多个mapper的情况

[abel533]

我会增加多个mapper.

[leimbag]

期待您的多mapper模式

[abel533]

我在项目中又新增了2个表和对应的实体、Mapper，你可以下载最新代码试试这个问题。

赞，赶紧更新做了尝试，发现问题依旧，启动后会出现WARN，并且每个mapper重复3遍。

本次完全重新pull，仅修改了数据库连接地址和端口，感觉问题很诡异，附加本次相关的环境信息及日志，希望有所帮助。pom文件没有动过。另求一下您的编译环境。感觉这个问题很诡异，使用IDEA和mvn编译结果都一样。相关信息如下：

原来同有，我一开始想解决这个WARN，跟踪spring代码跟的晕了，对于会重复加载固定的3遍比较困惑，跟踪发现主要是在sqlSessionFactory加载时报错。不过在换为官方的spring-mybatis时，却没有该警告，不知道是不是和tk包里的MapperScannerConfigurer实现有关系。

我找时间和mybatis-starter对比看看。

这个bug是mybatis-spring的，换到最新的1.2.4版本就没问题了。

详细内容看这里:mybatis/spring#58

赞，已更新1.2.4尝试，并且需将通用mapper升级为3.3.6后，启动无warn。

today, i meet the same problem ，but when i try

        <groupId>org.mybatis</groupId>
        <artifactId>mybatis-spring</artifactId>
        <version>1.3.1</version>

this problem gone away, i guess this bug is belong to mybatis-spring
