面临的麻烦,

通过Java的反射可以很方便,高效,易读的实现

先看一个Json对像

{ "content":[{
"level":1,
"status":"2",
"businessLicence":true,
"hygieneLicence":true,
"note":"note1",
"enterprise":"free",
"principal":"老韩",
"phone":"13366350377",
"time":1380862998588,
"address":"bj aa",
"latitude":38.112,
"longitude":116.002
}
,{
"level":2,
"status":"3",
"businessLicence":false,
"hygieneLicence":false,
"note":"note22222222222222222222222",
"enterprise":"鹏程万里",
"principal":"韩工",
"phone":"13366350377",
"time":1380962998588,
"address":"bj aa",
"latitude":38.112,
"longitude":116.002
}
,{
"level":3,
"status":"4",
"businessLicence":true,
"hygieneLicence":false,
"note":"海天3 note333333333333333333333333333",
"enterprise":"csdn",
"principal":"韩工",
"phone":"13366350377",
"time":1380943998588,
"address":"bj aa",
"latitude":38.112,
"longitude":116.002
}]
}

一个Json对像

对应的 Java对像

public class Content {

private int level;
private String status;
private boolean businessLicence;
private boolean hygieneLicence;
private String note;//
private String enterprise;
private String principal;
private long time;
private String address;
private double latitude;
private double longitude;
private String phone;

private final String[] properties = {"level",
"phone",
"status",
"businessLicence",
"hygieneLicence",
"note",
"enterprise",
"principal",
"time",
"address",
"latitude",
"longitude"
};

public Content() {
time = System.currentTimeMillis();
init();
}

public Content(JSONObject jObj) {
if (null == jObj) {
time = System.currentTimeMillis();
return;
}
init();
try {
fromJSONObject(jObj);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

public String getCategory() {
// TODO Auto-generated method stub
return category;
}

public JSONObject toJSONObject() {
// TODO Auto-generated method stub
return null;
}

public Content fromJSONObject(JSONObject jObj) throws JSONException {
if (null == jObj)
return null;
Object obj;
for (String property : properties) {
if (jObj.has(property)) {
obj = jObj.get(property);

// 方法1:
// 比较文明,调用类的set 方法进行赋值.
setProperty("set" + property, obj);
// 方法2:
// 直接对属性赋值,有点野蛮
// this.getClass().getDeclaredField(property).set(property, v);
// Field field = this.getClass().getDeclaredField(property);
// boolean accessible = field.isAccessible();
// field.setAccessible(true);
// field.set(this, v);
// field.setAccessible(accessible);
}
}

return this;
}

/** 下面是常用的老土的方法,全是体力活 :
*
*/
public Content fromJSONObject2(JSONObject jObj) throws JSONException {
if (null == jObj)
return null;
