maven整合ssm遇到的小问题1

一、在maven整合ssm框架时spring-mybatis.xml文件的classpath值使用下面的是会报错的

 ContextLoader:319 - Context initialization failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [spring.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed

<property name="dataSource" ref="dataSource" />
<property name="mapperLocations" value="classpath:book/dao/*Mapper.xml"
/>
<property name="typeAliasesPackage" value="book.pojo"></property>
</bean>

得改成下面的方式

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="dataSource" />
<property name="mapperLocations" value="book.dao.*Mapper.xml" />
<property name="typeAliasesPackage" value="book.pojo"></property>
</bean>
