Java树结构

   今天在项目中，运用到了Java树结构，是在一个查询中，选择树结构例如图片

  

该结构采用了前段的最新的知识，通过xml结构的数据库，后端Spring的映射实现的。

代码示例：

数据库：

    
        <if test="taxtypeCode != null and taxtypeCode !='' ">
            SELECT aa.taxtype_code, SUM( aa.amount ) amount, d.label AS taxtype_name
            FROM (
        if>
        SELECT e.taxtype_code, SUM( e.amount ) amount, e.taxtype_name FROM(
        SELECT
        e.taxtype_code, e.amount, e.taxtype_name
        FROM ${jdbc.prefix}sys_electronic_tax_done e
        INNER JOIN ${jdbc.prefix}sys_company c ON c.id=e.company_id
        WHERE 1
        <if test="cp != null and cp.isEmphases!=null">
            and c.is_emphases=#{cp.isEmphases}
        if>
        <if test="cp != null and cp.isSmall!=null">
            and c.is_small=#{cp.isSmall}
        if>
        <if test="currentMonth != null and currentMonth !='' ">
            AND e.accounting REGEXP #{currentMonth}
        if>
        <if test="startAmount != null and startAmount !='' "> 
                =#{startAmount}]]>
        if>
        <if test="startTime!=null and lastTime!=null">
                = #{startTime} AND e.accounting <= #{lastTime}]]>
        if>
        <if test="lastAmount != null and lastAmount !='' "> 
                
        if>

        <if test="taxpayerSn!=null and taxpayerSn!=''">
            AND e.taxpayer_sn=#{taxpayerSn}
        if>
        <if test="taxtypeCode != null and taxtypeCode !='' ">
            AND e.taxtype_code REGEXP CONCAT('^(', #{taxtypeCode}, ')')
        if>
        ) e GROUP BY e.taxtype_code
        <if test="taxtypeCode != null and taxtypeCode !='' ">
            )aa INNER JOIN ${jdbc.prefix}sys_dict d ON aa.taxtype_code REGEXP
            CONCAT('^', d.`value`) WHERE `value` REGEXP CONCAT('^(',
            #{taxtypeCode}, ')$') AND d.type='taxtype_code' GROUP BY `value`
        if>
        ORDER BY amount DESC
    

后台action层：

/**
     * 企业税种分布统计
     * 
     * @return
     */
    @RequiresPermissions("analysis:analysis:getCompanyTaxTwelveTotal")
    @RequestMapping(value = "/analysis/analysis/companyTaxTypeDistribution")
    public String companyTaxTypeDistribution()
    {
        List yearMonthList = companyService.getYearMonth();
        Page page = new Page(request, response);
        page.setPageSize(10);
        
        el.setCurrentMonth(null);
        el.setStartTime(yearMonthList.get(11) + "-01");
        el.setLastTime(yearMonthList.get(0) + "-01");
        
        List taxList = companyService.getElectronicTaxDao().getTaxTypeDistribution(el);
        page = companyService.getTaxTypeDistribution(page, el);
        
        model.addAttribute("taxList", taxList);
        model.addAttribute("page", page);
        model.addAttribute("yearMonthList", yearMonthList);
        
        return "addons/analysis/analysis/companyTaxTypeList";
    }
