android

前言

今天给大家分享一个以前学习SSM的实战项目,一个使用springmvcmybatisjequerybootstrapueditor打造的论坛系统,主要包含论坛主体,后台管理两个部分。
git地址如下:https://github.com/jsbintask22/bbs.git

技术介绍

该系统主要使用服务端主要使用spring,mybatis进行搭建,前端主要为bootstrap,jquery编写的jsp页面,并且集成百度ueditor进行富文本编辑,功能实现,技术点如下:
用户注册:用户如若要进行发帖,回帖等操作,必须先注册账号。注册账号使用邮箱进行注册(邮件发送),使用ajax验证邮箱,用户名唯一性。
用户登录: 用户登录需输入验证码,验证码为请求登陆页面时后台生成图片,记录到session中。
权限验证:系统中某些行为必须进行登陆方可操作,所以必须提供同意权限验证,此系统主要使用拦截器(Interceptor)进行用户的权限验证。
用户发帖:已登陆的用户可以进行发帖,回帖。提供直接图片,文件上传功能,此处前端使用UEDITOR配合后端文件上传实现。
用户回帖:用户可以回复某一帖子,并且可以引用。所以此处设计数据库设计 树状结构的表设计。
帖子收藏:用户可以收藏喜欢的帖子,并且在个人中心中找到。
用户关注:用户可以关注其他用户。
个人信息:用户可以查看个人信息,修改维护个人信息,并且设置头像。
帖子管理:后台主要功能为对帖子进行维护,可以及时删除,恢复已经存在的帖子。

import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

//实现一个拦截器,进行用户的权限控制
public class PostTopicInter implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {

boolean flag = false;
User user = (User) httpServletRequest.getSession().getAttribute("user");
if(user!=null) {
if(user.getStatus()==0) {
httpServletRequest.setAttribute("message", "对不起,您已被管理员禁言,请联系管理员进行处理");
httpServletRequest.getRequestDispatcher("/topic/all").forward(httpServletRequest, httpServletResponse);
} else {
flag = true;
}
} else {
httpServletRequest.setAttribute("message", "请先登录再进行操作");
httpServletRequest.getRequestDispatcher("/user/userLogin").forward(httpServletRequest, httpServletResponse);
}
return flag;
}

@Override

}

@Override
public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {

</mvc:interceptor>

<mvc:interceptor>
<mvc:mapping path="/admin/**"/>
<mvc:exclude-mapping path="/admin/login"/>
<!--由于拦截器在controller之前执行,所以这个地址也要拦截掉才行-->
<mvc:exclude-mapping path="/admin/index"/>
<bean class="cn.jsbintask.bbs.interceptor.AdminInterceptor"/>
</mvc:interceptor>
</mvc:interceptors>

message.setContent(
"<h1>您的验证码:<span style='color=red'>" + code + "</span></h1>",
"text/html;charset=UTF-8");
Transport.send(message);
}

注意此处邮箱,密码修改为自己的。
