如何解决spring整合mybatis报错，如下所示：
配置文件
driver=com.mysql.jdbc.Driver
url=jdbc:mysql:///ssm?serverTimezone=UTC&useSSL=false
username=root
password=1234
<!--加载外部配置文件-->
<context:property-placeholder location="db.properties"/>
<!--配置数据源-->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${driver}"/>
<property name="url" value="${url}"/>
<property name="username" value="${username}"/>
<property name="password" value="${password}"/>
</bean>
<!-- 配置sqlsessionfactoryBean -->
<bean id="SqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="typeAliasesPackage" value="com.qianli.pojo"/>
<property name="mapperLocations" value="com/qianli/mapper/*.xml"/>
</bean>
<!-- 配置sqlsessionTemplate-->
<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg name="sqlSessionFactory" ref="SqlSessionFactoryBean"/>
</bean>
<!--配置业务层-->
<bean id="userService" class="com.qianli.service.impl.UserServiceImpl">
<property name="sqlSessionTemplate" ref="sqlSessionTemplate"/>
</bean>mapper
