修改org.json.JSONObject的stringToValue，返回能容纳整数的最小包装类型而不是Integer。

（修正数据交互工具中当对象包含属性的类型为类型为byte/short时反射调用field.set(bean,obj)引发异常。）

黑色粗体斜体为增加部分，修改后代码如下：

static public Object stringToValue(String s) {
if (s.equals("")) {
return s;
}
if (s.equalsIgnoreCase("true")) {
return Boolean.TRUE;
}
if (s.equalsIgnoreCase("false")) {
return Boolean.FALSE;
}
if (s.equalsIgnoreCase("null")) {
return JSONObject.NULL;
}

/*
* If it might be a number,try converting it.
* We support the non-standard 0x- convention.
* If a number cannot be produced,then the value will just
* be a string. Note that the 0x-,plus,and implied string
* conventions are non-standard. A JSON parser may accept
* non-JSON forms as long as it accepts all correct JSON forms.
*/

char b = s.charAt(0);
if ((b >= '0' && b <= '9') || b == '.' || b == '-' || b == '+') {
if (b == '0' && s.length() > 2 &&
(s.charAt(1) == 'x' || s.charAt(1) == 'X')) {
try {
return new Integer(Integer.parseInt(s.substring(2),16));
} catch (Exception ignore) {
}
}
try {
if (s.indexOf('.') > -1 ||
s.indexOf('e') > -1 || s.indexOf('E') > -1) {
return Double.valueOf(s);
} else {
Long myLong = new Long(s);
if (myLong.shortValue() == myLong.byteValue()) {
return new Byte(myLong.byteValue());
} if (myLong.intValue() == myLong.shortValue()) {
return new Short(myLong.shortValue());
} if (myLong.longValue() == myLong.intValue()) {
return new Integer(myLong.intValue());
} else {
return myLong;
}
}
} catch (Exception ignore) {
}
}
return s;
}

还有org.json.JSONObject中增加：

/** * Put a key/int pair in the JSONObject. * * @param key A key string. * @param value An int which is the value. * @return this. * @throws JSONException If the key is null. */ public JSONObject put(String key,byte value) throws JSONException { put(key,new Byte(value)); return this; } /** * Put a key/int pair in the JSONObject. * * @param key A key string. * @param value An int which is the value. * @return this. * @throws JSONException If the key is null. */ public JSONObject put(String key,short value) throws JSONException { put(key,new Short(value)); return this; }
