Exception encountered during context initialization - cancelling refresh attempt

Exception encountered during context initialization - cancelling refresh attempt:

org.springframework.beans.factory

默认类路径在spring-dao.xml

Error creating bean with name ‘sqlSessionFactory’ defined in class path resource [spring-dao.xml]

上下文初始化期间遇到异常 - 取消刷新尝试：

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory

看报错信息让我检查 com/wei/Mapper/UserMapper.xml

please check com/wei/Mapper/UserMapper.xml and file [D:\Java\Spring_Projects\Spring-10-mybatis\target\classes\com\wei\Mapper\UserMapper.xml]

总结：

得出错误出现在com/wei/Mapper/UserMapper.xml 中

检查UserMapper.xml 发现没有错误，只能去检查映射文件mybatis-config.xml 发现

UserMapper.xml中写了映射文件class加载方式

<mappers>

   <mapper class="com.wei.Mapper.UserMapper"/>

</mappers>

而spring-dao.xml中也书写了映射文件加载方式

<property name="mapperLocations" value="classpath:com/wei/Mapper/*.xml"/>

总结：

两处的映射文件加载方式冲突了，所以系统报错信息才会说defined in class path resource [spring-dao.xml]
