org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.jdbc.datasource.DataSourceTransactionManager#0' defined in class path resource [spring-mybat

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.jdbc.datasource.DataSourceTransactionManager#0' defined in class path resource [spring-mybatis.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.String' to required type 'javax.sql.DataSource' for property 'dataSource'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [javax.sql.DataSource] for property 'dataSource': no matching editors or conversion strategy found

错误产生的原因 spring-mybatis.xml文件的下面一段出错，

<bean
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
        <property name="defaultTimeout" value="10000" />
    </bean>
