Json字符串转换对象

首先创建一个实体类。

public class PatientPhoneLocation {
	
	// 省
	private String prov;
	// 市
	private String city;
	
	public String getProv() {
		return prov;
	}
	public void setProv(String prov) {
		this.prov = prov;
	}
	public String getCity() {
		return city;
	}
	public void setCity(String city) {
		this.city = city;
	}
	
}

 下面的方法是解析字符串方法。

public static void main(String[] args) {
		PatientPhoneLocation phoneLocation = jsonToLocation (\"{\'ret\':200,\'msg\':\'success\',\'data\':{\'types\':\'中国移动\',\'lng\':\'116.407526\',\'city\':\'北京\',\'num\':\'1352251\',\'isp\':\'移动\',\'area_code\':\'110100\',\'city_code\':\'010\',\'prov\':\'北京\',\'zip_code\':\'100000\',\'lat\':\'39.90403\'},\'log_id\':\'4001EB1D-3528-48C4-9F13-11723DD043F4\'}\");
		System.out.println(phoneLocation.getProv());
		System.out.println(phoneLocation.getCity());
}
	 
	
public static PatientPhoneLocation jsonToLocation (String resultJson) {
		 String htmlEncodeByRegExp = htmlEncodeByRegExp(resultJson);
		 JSONObject jsonObject = JSONObject.fromObject(htmlEncodeByRegExp);
		 JSONObject jsonObj= jsonObject.getJSONObject(\"data\");
		 PatientPhoneLocation phoneLocation = (PatientPhoneLocation)net.sf.json.JSONObject.toBean(jsonObj, PatientPhoneLocation.class);
		 return phoneLocation;
}
private static String  htmlEncodeByRegExp(String str){
	        String s = \"\";
	        if(str.length() == 0) return \"\";
	        s = str.replace(\"\\n\",\" \");
	        s = s.replace(\"\\r\",\" \");
	        return s;
}

希望可以帮助到大家。
