SSM框架下实现简单的统计点击数功能

先贴上效果图

怎么做这个小功能

我这里先贴上我的代码，具体的解释以后有空加上
实现很容易，
就是前端页面用 js 的 onclick 事件
记录点击，
每点击一次
在控制器中向后台数据库update相关字段+1
就可以了

1，控制器

2，实体类

package com.infopublic.entity;

import java.util.Date;

public class TbEducation {
    private Integer eid;

    private String courtit;

    private String coursum;

    private String courass;

    private String adddate;

    private String uid;

    private String uname;

    private String courpic;

    private Short remark;

    public Integer getEid() {
        return eid;
    }

    public void setEid(Integer eid) {
        this.eid = eid;

    public String getUname() {

        return remark;
    }

    public void setRemark(Short remark) {
        this.remark = remark;
    }
}

3，业务接口

EduManager.java

package com.infopublic.service;

import java.util.List;

import com.infopublic.entity.TbEducation;
import com.infopublic.util.PageData;

/**
 * 在线学习接口类
 * @author zc
 *
 */
public interface EduManager {

    /**
     * 展示学习内容
     * @param pd
     * @return
     * @throws Exception
     */
    public List getEdu(PageData pd)throws Exception;

    /**
     * 根据eid展示
     * @param pd
     * @return
     * @throws Exception
     */
    public TbEducation getEduFromeid(PageData pd)throws Exception;

    /**
     * 新增courread点击量
     * @param pd
     * @return
     * @throws Exception
     */
    public TbEducation setEduCourread(PageData pd)throws Exception;

}

4，业务逻辑

EduService.java

package com.infopublic.service.impl;


import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.infopublic.dao.DaoSupport;
import com.infopublic.entity.TbEducation;
import com.infopublic.service.EduManager;
import com.infopublic.util.PageData;

@Service("EduService")
public class EduService implements EduManager{ 
    @Resource(name = "daoSupport") 
    private DaoSupport dao; 

    @SuppressWarnings("unchecked")
    @Override
    public List getEdu(PageData pd) throws Exception {
        return (List)dao.findForList("TbEduMapping.getEdu", pd);
    }
    @Override
    public TbEducation getEduFromeid(PageData pd) throws Exception {
        return (TbEducation)dao.findForObject("TbEduMapping.getEduFromeid", pd);
    }
    @Override
    public TbEducation setEduCourread(PageData pd) throws Exception {
        return (TbEducation)dao.findForObject("TbEduMapping.setEduCourread", pd);
    }

}

5，Mabatis数据库管理

TbEduMapper.xml

    <mapper namespace="TbEduMapping">
    
    <sql id="edutable">
        tb_education
    sql>

    <sql id="edu">

    sql>

    
    <select id="getEdu" parameterType="pd" resultType="TbEducation">
    select 
    eid,courtit,coursum,courass,adddate,uid,uname,courread,courpic,remark
    from <include refid="edutable">include> 
    order by adddate desc
    limit ${begin},${length}
    select>

    
    <select id="getEduFromeid" parameterType="pd" resultType="TbEducation">
    select 
    eid,courtit,coursum,courass,adddate,uid,uname,courread,courpic,remark
    from <include refid="edutable">include> 
    where eid=#{eid} 
    select>

    
    <update id="setEduCourread" parameterType="pd" >
    
        update <include refid="edutable">include>  set courread=#{courread}  
        where eid=#{eid}
      update>

嗯，把实现整个页面的所有相关代码已经贴上了。
等有时间再写一个详细的解释吧。
