第16章 登录功能
报错如下：
怎样解决啊？？？？
作者你好，第8章里的小项目水果商品列表，我部署在tomcat上后能访问localhost:8080，但是访问项目就出现404，也没有任何报错信息，请问应该怎么解决啊
阅读过程中发现的几个小问题：
第一：69页：倒数第9行“resultMap配置将select id id_,username”,其中将_id错误写成id(此处有个下划线)了;
第二：97页：第18行“全局配置文件SqlapConfig.xml”少写一个M，应该是：SqlMapConfig.xml；
前面两个拼写问题只是影响阅读，不影响程序运行，接下来一个问题直接导致程序中断
第三：97页：倒数第9行“<setting name="lazyLoadingEnable" value="true" />”其中lazyLoadingEnable少写一个d,应该是lazyLoadingEnabled。
整体讲解的清晰明了，案例丰富，还在学习中，后续发现问题再来留言。
