处理Echart的Util类以及使用案例

 

Util类代码：

package com.allcheer.mshpms.util;

import java.util.List;
import java.util.Map;

public class BjuiEchartUtil {

    private StringBuffer option;

    private String title;

    private List<String> legendName;

    private List<String> xAxisData;

    private Map<String,List<String>> seriesMap;
    
    public BjuiEchartUtil(String title,List<String> legendName,List<String> xAxisData,Map<String,List<String>> seriesMap){
        this.title = title;
        this.legendName = legendName;
        this.xAxisData = xAxisData;
        this.seriesMap = seriesMap;
    }

    public String getOption() {
        StringBuffer titles = new StringBuffer("\"title\":{\"text\":\""+title+"\"},");
        
        StringBuffer tooltip = new StringBuffer("\"tooltip\": {\"trigger\": \"axis\"},");
        
        StringBuffer legend = new StringBuffer("\"legend\": {\"data\": [ ");
        for(String legendN:legendName){
            legend.append("\""+legendN+"\",");
        }
        legend.deleteCharAt(legend.length()-1);
        legend.append("]},");
        
        StringBuffer toolbox = new StringBuffer("\"toolbox\": {\"show\": true,\"feature\": {\"mark\": {\"show\": true},\"dataView\": {\"show\": true,\"readOnly\": false},\"magicType\": {\"show\": true,\"type\": [\"line\",\"bar\"]},\"restore\": {\"show\": true},\"saveAsImage\": {\"show\": true}}},");
        StringBuffer calculable = new StringBuffer("\"calculable\": true,");
        
        StringBuffer xAxis = new StringBuffer("\"xAxis\": [{\"type\": \"category\",\"data\": [ ");
        for(String data:xAxisData){
            xAxis.append("\""+data+"\",");
        }
        xAxis.deleteCharAt(xAxis.length()-1);
        xAxis.append("]}],");
        
        StringBuffer yAxis = new StringBuffer(" \"yAxis\": [{\"type\": \"value\",\"splitArea\": {\"show\": true}}],");
        
        StringBuffer series = new StringBuffer("\"series\": [ ");
        for(String legendName : seriesMap.keySet()){
            series.append("{\"name\": \"");
            series.append(legendName).append("\",\"type\": \"bar\",\"data\": [ ");
            List<String> list = seriesMap.get(legendName);
            for(String data : list){
                series.append(data+",");
            }
            series.deleteCharAt(series.length()-1);
            series.append("]},");
        }
        series.deleteCharAt(series.length()-1);
        series.append("]");
        
        option = new StringBuffer("{");
        option.append(titles).append(tooltip).append(legend).append(toolbox).append(calculable).append(xAxis).append(yAxis).append(series).append("}");
        return option.toString();
    }
}

拼接数据代码：

public String getRegisterChartData(StatisticalRegisterTypeEnum type, String start, String end){
        Calendar endTime = Calendar.getInstance();
        Calendar startTime = Calendar.getInstance();
        startTime.add(Calendar.DAY_OF_MONTH, -Integer.parseInt("7"));
        String startDate = DateFormatUtils.format(startTime, StatisticalService.DATE_PATTERN);
        String endDate = DateFormatUtils.format(endTime, StatisticalService.DATE_PATTERN);
        if(start != null && !"".equals(start.trim())){
            startDate = start;
        }
        if(end != null && !"".equals(end.trim())){
            endDate = end;
        }
        List<StatisticalRegisterDataDO> list = new ArrayList<StatisticalRegisterDataDO>();

        StatisticalRegisterDataDOExample example = new StatisticalRegisterDataDOExample();
        example.createCriteria().andStatisticalTypeEqualTo(type.getType()).andStatisticalDateGreaterThanOrEqualTo(startDate).andStatisticalDateLessThanOrEqualTo(endDate);
        list = statisticalRegisterDataDOMapper.selectByExample(example);

        String title = type.getChartTitle();
        List<String> xAxisData = new ArrayList<String>();
        List<String> legendName = new ArrayList<String>();
        Map<String,List<String>> seriesMap = new HashMap<String,List<String>>();

        if(type.getType().equals("0")){//三方
            StatisticalRegisterThirdTypeEnum[] gradEnums = StatisticalRegisterThirdTypeEnum.values();
            List<String> dataValue = null;
            for(StatisticalRegisterThirdTypeEnum grad:gradEnums){
                legendName.add(grad.getLegendName());
                dataValue = new ArrayList<String>();
                seriesMap.put(grad.getLegendName(), dataValue);
                for(StatisticalRegisterDataDO data:list){
                    if(grad.getType().equals(data.getStatisticalKey())){
                        dataValue.add(data.getRegisterValue()+"");
                    }
                    if(!xAxisData.contains(data.getStatisticalDate())){
                        xAxisData.add(data.getStatisticalDate());
                    }
                }
            }
        }else if(type.getType().equals("1")){

        }else if(type.getType().equals("2")){

        }

        BjuiEchartUtil option = new BjuiEchartUtil(title,legendName,xAxisData,seriesMap);
        return option.getOption();
    }
