SSM,Jqeury, Bootstrap从零打造一个论坛系统

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。

权限验证

权限主要使用springmvc拦截器进行处理,拦截未登录的用户,发帖,回帖等信息:

package cn.jsbintask.bbs.interceptor;

import cn.jsbintask.bbs.po.User;
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 {
        System.out.println("进入了拦截器页面");
        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
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {

    }

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

    }
}

相应配置文件如下:

<!--定义拦截器-->
<mvc:interceptors>
    <mvc:interceptor>
        <mvc:mapping path="/topic/postTopic"/>
        <mvc:mapping path="/article/postArticle" />
        <mvc:mapping path="/topic/collectTopic"/>
        <mvc:mapping path="/otherSpace/attentionUser"/>
        <bean class="cn.jsbintask.bbs.interceptor.PostTopicInter" />
    </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>

邮件发送

邮件发送为注册用户时接受注册验证码时使用,关键代码如下:

public static void sendMessage(String to, String code) throws Exception {
		Properties props = new Properties();
		String from = "Jsbintask@163.com";
		String smtpUrl = "smtp." + from.split("@")[1];
		
		props.put("mail.smtp.auth", "true");
	    props.put("mail.smtp.host", smtpUrl);
		
		Session session = Session.getInstance(props, new Authenticator() {

			@Override
			protected PasswordAuthentication getPasswordAuthentication() {
				return new PasswordAuthentication("Jsbintask@163.com", "xxxxxx");
			}
		});

		Message message = new MimeMessage(session);
		message.setFrom(new InternetAddress("Jsbintask@163.com"));
		message.setRecipient(RecipientType.TO, new InternetAddress(to));
		System.out.println("BBSCheckCode");
		message.setSubject("激活码");
		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。
