fastJson json字符串转javabean对象

举例说明：

现在有一个返回的json字符串数据，如下所示：

{
 "data": {
"blry": "张三",
"jdmc": "lll",
"myd": "1",
"pjsj": "2018-10-17 14:16:35",
"sqrlxfs": "18673892546",
"sqrxm": "jsonchen",
"ywbh": "201710180209"
},
"head": {
"token": "6FC1E11F1A3CE72377817F286FD1C70E",
"wdbs": "",
"xzqdm": ""
}
}

现在要将该json字符串转为bean对象的形式，分析json字符串得出，一个大的对象里面包括两个小对象（复杂的json字符串也是可以这样推出来的）：

先创建最外面的对象，里面包括两个对象：

/**

*结果类

**/

public Class Result{

//第一个key为data的bean类

private DataBean data;

//第二个key为head的bean类

private HeadBean head;

public DataBean getData(){

return data;

}

 

public void setData(DataBean data){

this.data = data;

}

 

public HeadBean getHead(){

return head;

}

 

public void setHead(HeadBean head){

this.head = head;

}

}

接下来就是创建剩余的两个对象，注意保持bean类和字符串的属性名对应起来，否则可能会出现错误：

package com.moke.vo;
/**
*数据对象类
**/
public class DataBean {
    private String  blry;
    private String  jdmc;
    private String  myd;
    private String  pjsj;
    private String  sqrlxfs;
    private String  ywbh;
    private String  bmyyy;
    private String  sqrxm;

    public String getBlry() {
        return blry;
    }

    public void setBlry(String blry) {
        this.blry = blry;
    }

    public String getJdmc() {
        return jdmc;
    }

    public void setJdmc(String jdmc) {
        this.jdmc = jdmc;
    }

    public String getMyd() {
        return myd;
    }

    public void setMyd(String myd) {
        this.myd = myd;
    }

    public String getPjsj() {
        return pjsj;
    }

    public void setPjsj(String pjsj) {
        this.pjsj = pjsj;
    }

    public String getSqrlxfs() {
        return sqrlxfs;
    }

    public void setSqrlxfs(String sqrlxfs) {
        this.sqrlxfs = sqrlxfs;
    }

    public String getYwbh() {
        return ywbh;
    }

    public void setYwbh(String ywbh) {
        this.ywbh = ywbh;
    }

    public String getBmyyy() {
        return bmyyy;
    }

    public void setBmyyy(String bmyyy) {
        this.bmyyy = bmyyy;
    }

    public String getSqrxm() {
        return sqrxm;
    }

    public void setSqrxm(String sqrxm) {
        this.sqrxm = sqrxm;
    }
}

 

package com.moke.vo;
/**
*头部对象类
**/
public class HeadBean {
    private String  wdbs;
    private String  token;
    private String  xzqdm;

    public String getWdbs() {
        return wdbs;
    }

    public void setWdbs(String wdbs) {
        this.wdbs = wdbs;
    }

    public String getToken() {
        return token;
    }

    public void setToken(String token) {
        this.token = token;
    }

    public String getXzqdm() {
        return xzqdm;
    }

    public void setXzqdm(String xzqdm) {
        this.xzqdm = xzqdm;
    }
}
之后使用fastjson中的方法将json字符串转为javabean类：

public static void testJSONStrToJavaBeanObj(){

        Result result = JSON.parseObject(上面的json字符串, new TypeReference() {});
        //Student student1 = JSONObject.parseObject(json字符串, new TypeReference() {});//因为JSONObject继承了JSON，所以这样也是可以的

        System.out.println(result.getData().getBlry()+":"+result.getHead().getxzqdm());//这样就可以获取到相应对象中的值

    }
