先项目clean,然后maven里面选update试一下,有可能是缓存问题

而且就在这个包内,这什么情况啊..

<!-- 创建sqlSessionfactoryBean对象 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="ds"/> <property name="mapperLocations" value="classpath:mapper/*.xml"></property> <!-- 配置mybatis全局配置文件 --> <!-- <property name="configLocation" value="classpath:"></property> --> <!-- typeAliasesPackage: 指定哪个包下的实体对象采用别名 --> <property name="typeAliasesPackage" value="com.huike.bean"/> </bean> 在spring的配置文件配置了别名

BookDao.xml有错误

引用 3 楼 anchor1 的回复:

BookDao.xml有错误

我知道啊,不就说找不到book类吗

你重新编译一次。有可能是你把过程clean了之后，生成的class文件被删掉了，而你没有重新编译导致的
