我的解決辦法是UTIL功能createJsonObjects,使用:
JSONArray result = createJsonObjects(persons, "name", "name")
import org.springframework.beans.BeanUtils;
import org.springframework.util.Assert;
import org.springframework.util.ReflectionUtils;
import org.springframework.util.StringUtils;
public static JSONArray createJsonObjects(List<?> objs, String propertyNames, String jsonKeys)
{
Assert.hasText(propertyNames);
Assert.notNull(objs);
JSONArray result = new JSONArray();
String[] propertyNameArray = propertyNames.split(";");
String[] jsonKeysArray = propertyNameArray;
if (StringUtils.hasText(jsonKeys))
{
jsonKeysArray = jsonKeys.split(";");
}
Assert.isTrue(jsonKeysArray.length == propertyNameArray.length);
try
{
Method[] methods = new Method[ propertyNameArray.length ];
for (Object obj : objs)
{
for (int i = 0; i < propertyNameArray.length; i++)
{
methods[ i ] = BeanUtils.getPropertyDescriptor(obj.getClass(),
propertyNameArray[ i ]).getReadMethod();
}
JSONObject json = new JSONObject();
for (int i = 0; i < propertyNameArray.length; i++)
{
if (obj != null)
json.element(jsonKeysArray[ i ],
ReflectionUtils.invokeMethod(methods[ i ], obj));
}
result.add(json);
}
}
catch (Exception e)
{
throw new RuntimeException(e);
}
return result;
}
