解决方案
直接在SqlMapClientFactoryBean类的方法:protected SqlMapClient buildSqlMapClient(Resource[] configLocations, Resource[] mappingLocations, Properties properties)throws IOException {设置断点调试一下，看看到底传入的“configLocations”哪里不对。
解决方案二：
我把自己的配置改了，放到web-inf下，都是可以的啊：web.xml<context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/applicationContext.xml</param-value></context-param>applicationContext.xml<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><property name="configLocation" value="/WEB-INF/mybatis-config.xml"/></bean>日志出来正常：2011-08-12 13:07:58,593 WEB-MES [main] DEBUG o.m.s.SqlSessionFactoryBean - Parsed configuration file: 'ServletContext resource [/WEB-INF/mybatis-config.xml]'检查一下你文件的位置！
解决方案三：
这样， <property name="configLocation" value="/WEB-INF/sqlMapConfig.xml" /> “WEB-INF”前面加个斜杠。
解决方案四：
sqlMapConfig.xml和spring配置在同一目录的话，直接把 <property name="configLocation" value="WEB-INF/sqlMapConfig.xml" /> 改成： <property name="configLocation" value="sqlMapConfig.xml" /> 再试试。
解决方案五：
引用这个是公司的项目，不能这样子改配置的，有其他的办法米？ 你spring的配置文件放在哪里？
解决方案六：
这孩子，一碰到问题就问
解决方案七：
<property name="configLocation" value="WEB-INF/sqlMapConfig.xml" /> 这个设置的地址不对，这样不是绝对路径，spring找不到。你把sqlMapConfig.xml放到classes里面去，然后把这个改成：<property name="configLocation" value="classpath:sqlMapConfig.xml" />
解决方案八：
引用我用的是ibatis 你这个是mybatis的配置，有区别吗？ibatis需要怎么配置呢？ 我有用到 原理的是一样的。如果是ibatis你要注入的是：org.springframework.orm.ibatis.SqlMapClientFactoryBean把我上面的SqlSessionFactoryBean替换就好了。
解决方案九：
你的DAO为什么没有注入sqlSessionFactory呢？我一般都是这样的：<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><property name="configLocation" value="classpath:mybatis-config.xml"/></bean><bean id="baseMybatisDao" class="com.realtech.mes.dao.BaseMybatisDAO"> <property name="sqlSessionFactory" ref="sqlSessionFactory"/> </bean>
解决方案十：
就是它说的意思，你这个userDao需要一个sqlMapClient（应该是通过属性设置）。你没有设置。于是在调用初始化函数的时候出错了。
