bootstrap-table分页第二篇 延续上一篇的

这个是service
/**
     * 返回记录数
     * @return
     */
    public Integer getPageTotal(Integer userid);

//service的实现类  
  public Integer getPageTotal(Integer userid) {
        return newsMessageMapper.getPageTotal(userid);
    }

/**   mapper
     * 返回记录数
     * @return
     */
    public Integer getPageTotal(@Param("userid")Integer userid);

//mapperxml文件   
 <select id="getPageTotal" resultType="int">
    select count(*) from news n
    where n.userID=#{userid}
    </select>

到此查询总记录数的方法已经写完，下面的分页查询的方法

/**  分页查询的service
     * 消息列表
     * @return
     */
    public List<News> showNewsList(Integer userid,Integer rows,Integer page);

//serviceimpl的实现类
public List<News> showNewsList(Integer userid,Integer rows, Integer page) {
        return newsMessageMapper.showNewsList(userid,rows,page);
    }

/**  分页查询的mapper
     * 消息列表
     * @return
     */
    public List<News> showNewsList(@Param("userid")Integer userid,@Param("rows")Integer rows, @Param("page")Integer page);

//mapperxml
<select id="showNewsList" resultType="com.yituo.noopsyche.model.News">
        select 
            n.id as id,
            n.headline as headline,
            n.content as content,
            u.staffName as staffName,
            d.name as name,
            nt.messageTypeName as messageTypeName,
            n.publishTime as publishTime,
            n.filepath as filepath
         from news n
             left join newsType nt on n.newTypeID=nt.id
             left join dept d on d.ID=n.deptID
             left join users u on u.ID=n.userID
             where u.ID=#{userid}
             ORDER BY n.publishtime desc
             LIMIT #{page},#{rows}
    </select>

在前台的js文件中，进行columns中的field必须要后台返回的属性对应，否则无法进行显示
