fastjson JSONObject

工作中用的蛮多的最近整理下，概括地说 通过这个工具可以让一个json在json串，JSONObject，java对象之间进行转化

首先我们先写2个bean来构成一个比较复杂的json串：

public class InnerBean {
    private String nickname;
    private String workcity;

    public String getNickname() {
        return nickname;
    }

    public void setNickname(String nickname) {
        this.nickname = nickname;
    }

    public String getWorkcity() {
        return workcity;
    }

    public void setWorkcity(String workcity) {
        this.workcity = workcity;
    }
}

import java.util.List;

public class TestBean {
    private String name;
    private Integer value;
    private boolean beTrue;
    private long number;
    private InnerBean innerBean;
    private List<InnerBean> innerBeanList;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getValue() {
        return value;
    }

    public void setValue(Integer value) {
        this.value = value;
    }



    public long getNumber() {
        return number;
    }

    public void setNumber(long number) {
        this.number = number;
    }

    public boolean isBeTrue() {
        return beTrue;
    }

    public void setBeTrue(boolean beTrue) {
        this.beTrue = beTrue;
    }

    public InnerBean getInnerBean() {
        return innerBean;
    }

    public void setInnerBean(InnerBean innerBean) {
        this.innerBean = innerBean;
    }

    public List<InnerBean> getInnerBeanList() {
        return innerBeanList;
    }

    public void setInnerBeanList(List<InnerBean> innerBeanList) {
        this.innerBeanList = innerBeanList;
    }
}

接着是相关的转换：

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;

import java.util.Arrays;

public class JsonObject {
    public static void main(String[] args) {
        TestBean testBean=new TestBean();
        testBean.setName("test");
        testBean.setNumber(123);
        testBean.setBeTrue(true);
        testBean.setValue(321);
        InnerBean innerBean=new InnerBean();
        innerBean.setNickname("dasda");
        innerBean.setWorkcity("asdasd");
        testBean.setInnerBean(innerBean);
        testBean.setInnerBeanList(Arrays.asList(innerBean,innerBean));

        //对象转json
        String beanToString=JSONObject.toJSONString(testBean);
        System.out.println("=======对象转json"+beanToString+"========");

        //json串转JSONObject
        JSONObject jsonObject=JSONObject.parseObject(beanToString);
//异常：字符串类型值test不能转
//        jsonObject.getDate("name");

        Object object=jsonObject.get("name");
        if (object instanceof JSONObject){
            System.out.println("=======JsonObject type=========");
        }
        System.out.println("name的值为："+object.toString());

        Object innerBeanObj=jsonObject.getJSONObject("innerBean");
        if (innerBeanObj instanceof JSONObject){
            System.out.println("======="+"innerBean的类型为"+"JsonObject type=========");
        }
        System.out.println(innerBeanObj.toString());

        JSONArray array= jsonObject.getJSONArray("innerBeanList");
        array.forEach(obj->{
            if (obj instanceof JSONObject){
                System.out.println("======="+"innerBeanList的类型为"+"JsonObject type=========");
                System.out.println(obj.toString());
            }
        });
    }
}
