同学好,

同学得会定位下错误信息,不用害怕上面的错误信息太长,只用研究自己看得懂的部分,往往会出现在"Caused by"附近,这里的错误是

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [spring/spring-dao.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'file [E:\JAVA\实战项目\O2O\target\classes\mapper\AreaDao.xml]'; nested exception is java.lang.RuntimeException: Error parsing Mapper XML. Cause: org.apache.ibatis.builder.BuilderException: Error resolving class. Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'com.liangwc.o2o.dao'.  Cause: java.lang.ClassNotFoundException: Cannot find class: com.liangwc.o2o.dao

即在xml配置文件里配置了com.liangwc.o2o.dao却找不到com.liangwc.o2o.dao这个类,是不是漏了com.liangwc.o2o.dao.类名?
