一大堆的错误，这里有一个小技巧，有些错误网上搜不到，当出现多条错误的时候，可以每条都在网上搜一下，可能会找到方法也说不动。这个问题困扰了我几天，最后惊奇的发现最重要的一条报错就是：

Caused by: org.apache.ibatis.builder.BuilderException: 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.myshoping.model.tb_customer'.  Cause: java.lang.ClassNotFoundException: Cannot find class: com.myshoping.model.tb_customer

是mapper包下的xml文件配置错了：

这里改成

<select id="check_login" resultMap="BaseResultMap" parameterType="com.shop.model.tb_customer" >

问题就解决了
