Question

进入httpInvoker后我遇到异常，它看起来像这样：

经过数小时的研究，我发现spring-db.xml是出现问题的地方。在那里有定义连接到例如com.mchange.v2.c3p0.ComboPooledDataSource或enviromentProperties。我一步一步地尝试，从那里逐行评论/解开一些东西，并且有部分定义如下：

   <!-- <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>

当我评论调用configurer的最后一个bean时，一切都顺利通过（毫无例外）。

如何停止获取该异常？也许我必须以其他方式编写那个bean？（抱歉没有给出完整的代码，我只能给它...）

我正在使用： Eclipse火星 Java 1.8 春季3.1 MyBatis的 32位Windows

如果您对以下行

发表评论，则不会显示上述异常

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

然后我相信你必须错过项目中的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>

将Spring与MyBatis一起使用时的Java异常
