多层json字符串转map_Java中Json字符串直接转换为对象的
⽅法（包括多层List集合）
使⽤到的类：net.sf.json.JSONObject
使⽤JSON时，除了要导⼊JSON⽹站上⾯下载的json-lib-2.2-jdk15.jar包之外，还必须有其它⼏个依赖包：commons-
beanutils.jar，commons-httpclient.jar，commons-lang.jar，ezmorph.jar，morph-1.0.1.jar
下⾯是例⼦代码：
// JSON转换
JSONObject jsonObj = JSONObject.fromObject(jsonStrBody);
Map classMap = new HashMap();
classMap.put("results", WeatherBean_Baidu_City.class);
classMap.put("index", WeatherBean_Baidu_City_Index.class);
classMap.put("weather_data", WeatherBean_Baidu_City_Weatherdata.class);
// 将JSON转换成WeatherBean_Baidu
WeatherBean_Baidu weather = (WeatherBean_Baidu) Bean(jsonObj,
WeatherBean_Baidu.class, classMap);
System.out.Results());
使⽤到的⼏个JAVA类代码：
package ity.vo;
import java.io.Serializable;
import java.util.List;
/**
* 天⽓Bean
*
* @author SHANHY
*
*/
@SuppressWarnings("serial")
public class WeatherBean_Baidu implements Serializable {
private String error;//错误号
private String status;//状态值
private String date;//⽇期
private List results;//城市天⽓预报集合(因为⼀次可以查询多个城市)
public WeatherBean_Baidu() {
super();
public String getError() {
return error;
}
public void setError(String error) {
< = error;
}
public String getStatus() {
return status;
}
public void setStatus(String status) { this.status = status;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
json转换对象public List getResults() {
return results;
}
public void setResults(List results) { sults = results;
}
}
