[大数据]疫情接口数据图表化

首先

我们的有效接口献上：https://c.m.163.com/ug/api/wuhan/app/data/list-total
打开之后就是一大波数据！非常惊人。我们来得到我想要的数据！

我就要了这几条数据

然后

我们建一个实体类

package com.nx.study.springstudy.bean;


public class XGBean {
    private int jwtoday;  // 境外
    private int jwyestoday;
    private int wzztoday;  // 无症状
    private int wzzyestoday;
    private int xytody;  // 现有
    private int xyyestody;
    private int ljtody;  // 累积
    private int ljyestoday;
    private int ljswtoday;  // 累积死亡
    private int ljswyestoday;
    private int ljzytoday;  // 累计治愈
    private int ljzyyestoday;

    @Override
    public String toString() {
        return "XGBean{" +
                "jwtoday=" + jwtoday +
                ", jwyestoday=" + jwyestoday +
                ", wzztoday=" + wzztoday +
                ", wzzyestoday=" + wzzyestoday +
                ", xytody=" + xytody +
                ", xyyestody=" + xyyestody +
                ", ljtody=" + ljtody +

                ", ljswtoday=" + ljswtoday +
                ", ljswyestoday=" + ljswyestoday +
                ", ljzytoday=" + ljzytoday +
                ", ljzyyestoday=" + ljzyyestoday +
                '}';
    }

    public int getJwtoday() {
        return jwtoday;
    }

    public void setJwtoday(int jwtoday) {
        this.jwtoday = jwtoday;
    }

    public int getJwyestoday() {
        return jwyestoday;
    }

    public void setJwyestoday(int jwyestoday) {
        this.jwyestoday = jwyestoday;
    }

    public int getWzztoday() {
        return wzztoday;
    }

    public void setWzztoday(int wzztoday) {
        this.wzztoday = wzztoday;
    }

    public int getWzzyestoday() {
        return wzzyestoday;
    }

    public void setWzzyestoday(int wzzyestoday) {
        this.wzzyestoday = wzzyestoday;
    }

    public int getXytody() {
        return xytody;
    }

    public void setXytody(int xytody) {
        this.xytody = xytody;
    }

    public int getXyyestody() {
        return xyyestody;
    }

    public void setXyyestody(int xyyestody) {
        this.xyyestody = xyyestody;
    }

    public int getLjtody() {
        return ljtody;
    }

    public void setLjtody(int ljtody) {
        this.ljtody = ljtody;
    }

    public int getLjyestoday() {
        return ljyestoday;
    }

    public void setLjyestoday(int ljyestoday) {
        this.ljyestoday = ljyestoday;
    }

    public int getLjswtoday() {
        return ljswtoday;
    }

    public void setLjswtoday(int ljswtoday) {
        this.ljswtoday = ljswtoday;
    }

    public int getLjswyestoday() {
        return ljswyestoday;
    }

    public void setLjswyestoday(int ljswyestoday) {
        this.ljswyestoday = ljswyestoday;
    }

    public int getLjzytoday() {
        return ljzytoday;
    }

    public void setLjzytoday(int ljzytoday) {
        this.ljzytoday = ljzytoday;
    }

    public int getLjzyyestoday() {
        return ljzyyestoday;
    }

    public void setLjzyyestoday(int ljzyyestoday) {
        this.ljzyyestoday = ljzyyestoday;
    }
}

有些数据我并没有用。我就获取了今日的数据。

下面来到功能代码
