今天学到了什么:

       经过一系列的增删扒抄成功配置好了一个基于RMI前后端分离的HelloWorld,

       但是忘记截图了,就不放图片了,

       参考链接 https://juejin.im/post/58720e8c1b69e6005ca6e306

       还有一个中文版的Rmi手册 http://www.10tiao.com/html/501/201705/2686978388/1.html

       然后在其基础上进行更改,改成可以查询数据库

       最结果是这样的:

       左边是Server右边是Client

再后来想通过前端页面进行查找操作,但是遇到了困难

遇到的困难:

这是一个demo所以类比较少,左边是前台,右边是后台

然后后端正常启动前端各种报错,先是tomcat端口冲突,改了端口还是冲突,直接使用tomcat结果报错

创建beans失败

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'categoryServiceImpl': Unsatisfied dependency expressed through field 'categoryMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.how2java.mapper.CategoryMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

目前尚未解决

收获:

       大概理解SpringRMI的工作过程

明天的计划:

       解决bug,把增删查改加上
