Hi all,
Here I am taking response data from JSON using jackson API.I found a feature like using Jackson the properties can be set to bean properties.
private static String readUrl(String urlString) throws Exception {
BufferedReader reader = null;
try {
URL url = new URL(urlString);
reader = new BufferedReader(new InputStreamReader(url.openStream()));
StringBuilder buffer = new StringBuilder();
int read;
char[] chars = new char[1024];
while ((read = reader.read(chars)) != -1) {
buffer.append(chars, 0, read);
}
return buffer.toString();
} finally {
if (reader != null) {
reader.close();
}
}
}
public static void main(String[] args) throws Exception {
ObjectMapper mapper = new ObjectMapper();
mapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);
JsonNode root = mapper.readTree(readUrl("myUrl"));
ArrayNode records = (ArrayNode) root.path("records");
Iterator<JsonNode> iterator = records.getElements();
while (iterator.hasNext()) {
OrderBean ord= mapper.readValue(iterator.next(),OrderBean.class);
System.out.println("OrderCode=" + ord.getOrderId() + " OrderDesc=" + ord.getOrderDesc());
}
}
I got the correct output here.
But now I want to generalize my method into a utility class so that I can reuse the same method for setting response data directly to respective beans as given below:-
My question is how will I pass the bean object in my utility class?
public static Object getResponseData(String response,[b]String bean[/b]) throws Exception {
ObjectMapper mapper = new ObjectMapper();
mapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);
JsonNode root = mapper.readTree(response);
ArrayNode records = (ArrayNode) root.path("records");
Iterator<JsonNode> iterator = records.getElements();
[b] Class<?> beanClass = Class.forName(bean);[/b]
while (iterator.hasNext()) {
[b] beanClass = mapper.readValue(iterator.next(), Class.class);[/b]
}
return bean;
}
