maven項目啟動報錯；class path resource [com/ssm/mapping/] cannot be resolved to URL because it does not exist

項目啟動報了一堆錯誤，其實都是class path resource [com/ssm/mapping/] cannot be resolved to URL because it does not exist這一個錯誤引起的

原來的session工廠的配置是這樣寫的

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <!-- 自動掃描entity目錄, 省掉Configuration.xml里的手工配置 -->
        <property name="mapperLocations" value="classpath:com/ssm/mapping/*.xml"></property>
    </bean>

把classpath后加上*號，所有的問題都解決了，更改后的代碼

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <!-- 自動掃描entity目錄, 省掉Configuration.xml里的手工配置 -->
        <property name="mapperLocations" value="classpath*:com/ssm/mapping/*.xml"></property>
    </bean>
