经过数小时的研究，我发现 spring-db.xml 是问题所在。其中有一些定义可以连接到例如 com.mchange.v2.c3p0.ComboPooledDataSource 或 enviromentProperties。我一步一步地尝试，从那里逐行注释/取消注释，其中部分定义如下：

   <!-- <tx:annotation-driven /> -->
    <tx:annotation-driven transaction-manager="transactionManager" /> 

    <!-- define the SqlSessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="typeAliasesPackage" value="hr.test.model" />
    </bean>


    <!-- scan for mappers and let them be autowired -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="hr.test.dao.api.mappers" />
    </bean>

当我评论最后一个调用配置器的 bean 时，一切顺利（无一例外）。

怎么做才能停止获得该异常？也许我必须以其他方式编写该 bean？（抱歉没有给出完整的代码，我被限制给出它..）

我正在使用：Eclipse Mars Java 1.8 Spring 3.1 MyBatis 32 位 Windows

如果您在以下行发表评论，则上述异常未显示

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="hr.test.dao.api.mappers" />
    </bean>

那么我相信你一定是在你的项目中缺少 mybatis-spring.jar 。请尝试在您的项目中包括以下内容：-

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.2.3</version>
</dependency>
