007_JSONObject对象静态方法

1. JSONObject.fromObject静态方法

1.1. JSONObject JSONObject.fromObject(Object object)静态方法, 把Map、JavaBean、JSON Object String对象转换为JSONObject对象。json-lib底层, 会创建一个JsonConfig对象使用。不能转换数组、集合, 需要用JSONArray转换。

1.2. JSONObject JSONObject.fromObject(Object object, JsonConfig jsonConfig)静态方法, 把Map、JavaBean、JSON Object String对象转换为JSONObject对象。并指定一个JsonConfig。

1.3. 新建Sensor.java

package com.fj.jo;

import java.io.Serializable;

/**
 * 传感器
 */
public class Sensor implements Serializable {
	private static final long serialVersionUID = 1L;
	
	private Boolean weightSensor; // 重力传感器
	private Boolean fingerSensor; // 指纹传感器
	private String otherSensor; // 其它传感器
	
	public Sensor() {}

	public Sensor(Boolean weightSensor, Boolean fingerSensor, String otherSensor) {
		this.weightSensor = weightSensor;
		this.fingerSensor = fingerSensor;
		this.otherSensor = otherSensor;
	}

	public Boolean getWeightSensor() {
		return weightSensor;
	}

	public void setWeightSensor(Boolean weightSensor) {
		this.weightSensor = weightSensor;
	}

	public Boolean getFingerSensor() {
		return fingerSensor;
	}

	public void setFingerSensor(Boolean fingerSensor) {
		this.fingerSensor = fingerSensor;
	}

	public String getOtherSensor() {
		return otherSensor;
	}

	public void setOtherSensor(String otherSensor) {
		this.otherSensor = otherSensor;
	}

	@Override
	public String toString() {
		return "{weightSensor=" + weightSensor + ", fingerSensor=" + fingerSensor + ", otherSensor=" + otherSensor + "}";
	}
}

1.4. 新建JSONObjectStaticFromObject.java

package com.fj.jo;

import java.util.HashMap;
import java.util.Map;
import net.sf.json.JSONObject;
import net.sf.json.JsonConfig;

/**
 * JSONObject
 * 1. JSONObject JSONObject.fromObject(Object object)静态方法, 把Map、JavaBean、JSON Object String对象转换为JSONObject对象。
 * json-lib底层, 会创建一个JsonConfig对象使用。不能转换数组、集合, 需要用JSONArray转换。
 * 2. JSONObject JSONObject.fromObject(Object object, JsonConfig jsonConfig)静态方法, 把Map、JavaBean、JSON Object String对象转换为JSONObject对象。并指定一个JsonConfig。
