Error creating bean with name 'sqlSessionFactory' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type 'java.lang.String' to required type 'org.springframework.core.io.Resource[]' for property 'mapperLocations'; nested exception is java.lang.IllegalArgumentException: Could not resolve resource location pattern [com/lee/mapper/*.xml]: ServletContext resource [/com/lee/mapper/] cannot be resolved to URL because it does not exist
今天在做SSM项目的时候启动发现报如上所示的错误，错误大致的意思就是无法创建一个名为sqlSessionFactory的bean，而且出错地方是mapperLocations，出现该错误可能是两种原因造成的。
一：<property name="mapperLocations" value="com/lee/mapper/*.xml"></property>
在value中没有加classpath:
改正：<property name="mapperLocations" value="classpath:com/lee/mapper/*.xml"></property>
二：可能有多个mapper.xml文件的namespace重复了。
