解決方法：

我遇到這個問題的原因是configuration引入錯了。 Cannot convert value of type 'java.lang.String' to required type 'org.apache.ibatis.session.Configuration' for property 'configuration': no matching editors or conversion strategy found。報錯中說的很清楚了。

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 指定MyBatis全局指定 -->
		<property name="configuration" value="classpath:mybatis-config.xml"></property>
		<property name="dataSource" ref="pooledDataSource"></property>
		<!-- 指定mybatis,mapper檔案位置 -->
		<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
	</bean>
           

configuration引入這個即可：
