How to parse XML with repeated XML tags into a POJO using Jackson?

由 久未见 提交于 2019-12-06 06:30:59
I am having issues with parsing this XML into a POJO using Jackson. I have read all the previous descriptions on making classes to de-serialise the XML into POJOS but I keep getting either Null pointers or not END of element warnings. I am extremely confused and any help is much appreciated. The input xml is <row> <entry align="right" valign="top">20</entry> <entry align="right" valign="top">1A</entry> <entry valign="top">SData</entry> <entry align="center" valign="top">2</entry> <entry valign="top">binary</entry> <entry valign="top">Java enterprise</entry> </row> The code I am using is;

问题 I've been using spring and hibernate for this past few weeks and I've always been learning something new there. Right now I've got a problem that I want to solve with Projections in Hibernate. Suppose there is a model Person and that model has many Car . The following are how the class definitions roughly gonna look like: public class Person implements java.io.Serializable { private Integer id; private String name; private List<Car> cars; private Integer minYear; // Transient private Integer

Conditional field requirement based on another field value in Jackson?

由 家住魔仙堡 提交于 2019-12-06 00:03:55
问题 Consider a JSON representation with one string and two arrays. For example, { "type" : "A", "ListA" : [] "ListB" : [3, 4, 5] } In the above case, type is required field, but ListA and ListB are conditionally required for deserialization based on the value of type . In other words, ListA is only required if type had value A and ListB is only required if type had a value B . Currently, I am working in Jackson and in Java, and I have been able to implement making type field mandatory by creating

primefaces autocomplete with pojo

由 房东的猫 提交于 2019-12-05 20:08:37
I read on SO some QA about the same component, but I feel I'm missing something, because I am one step behind. I can't even make the page open when using the primefaces autocomplete component in it. The snippet for it is: <p:autoComplete value="#{indirizzoCtrl.selectedCodiceNazione}" completeMethod="#{indirizzoCtrl.completeNazione}" var="nazione" itemLabel="#{nazione.nome}" itemValue="#{nazione.codiceNazione}" /> Nazione is a Pojo class where CodiceNazione and Nome are two String field (with getter and setter for sure). completeNazione is a method on the ManagedBean that returns List<Nazione>

Convert JSON into POJO (Object) similar to android in Flutter

由 自作多情 提交于 2019-12-05 20:01:01
I'm just trying to find a way to convert a json response (from a REST API) into POJO (As used in android) so that I can use the received data into my application as using Map wont be sufficient as the data i'm receiving is a little complex and contains 3 levels of arrays (arrays inside of arrays inside of arrays). I'm using Dio library for api calls and i can make API call successfully and print the data on the console with no issues at all. Can anyone assist me in achieving this? Below is the response i'm getting. { "status": 200, "message": "success", "data": [ { "menu": { "megamenu_id": "55

Mapping ResultSet to Pojo Objects

Well that's really embarrassing I have made a standard pojo class and its dao class for data retrieval purpose. I am having a difficulty to understand a basic procedure to how to handle a customized query data to Pojo class. let's say my User class is public class User{ private int userId; private String username; private int addressId; } public class Address{ private int addressId; private String zip; } public class UserDAO{ public void getUserDetails(){ String getSql = select u.userId, u.username, a.zipcode from user u, address a where u.addressId = a.addressId; //no pojo class is now

How to serialize a POJO into query params with Jersey

由 余生长醉 提交于 2019-12-05 11:04:20
I have been playing around and creating multiple small Java RESTful client libraries for different services at my company. Most of the time, I am unable to change anything on the server side and I need to write the Jersey pieces of code to interact with existing RESTful APIs. Context Up to know, I have been using Jersey with Jackson to use JSON: when I query a POJO I deserialize it from JSON, and when I need to send a POJO, I serialize it into a JSON body. This two kinds of snippets have been doing the job for me up to now... Querying and de-serialization ClientResponse response = webResource

What is the exact meaning of invasive? and what makes Spring non-invasive?

由 落花浮王杯 提交于 2019-12-05 10:00:08
问题 I'm new to the spring framework. In most of the Spring tutorials I saw, Spring is described as "non-invasive". What is meant by invasive? What are the merits of using Spring in Java and what makes it non-invasive? 回答1: If an IoC container is invasive, it means your code needs to be explicitly aware of dependency injection. For example, in Guice you use the @Inject annotation (and others). These annotations are more standardized than they used to be, which is good - it means with a single set

How to send a POJO as a callback param using PrimeFaces' RequestContext?

由 浪子不回头ぞ 提交于 2019-12-05 06:21:41
I can send callback param(s) and it works perfectly as long as I am only sending some primitive types like String. But the same thing does not work for even the simplest POJO. PrimeFaces guide says that the RequestContext.addCallbackParam() method can handle POJOs and it coverts them into JSON. I don't know why it's not working in my case. Has anybody done that? Solution found! --------------------------------------------------------------------- I did some research and found the answer to this question. And the solution was to use some JSON library (right now I am using GSON) to convert Java

Custom Class for JasperReports field

I would like to create a report with a custom class as follows: public class Class1 { String cl1_f1; String cl1_f2; } public class Class2 { String cl2_f1; String cl2_f2; Class1 cl1_ob1; } Now I pass Class2 in the report through fields and JRBeanCollectionDataSource. <subDataset name="myitems"> <field name="cl2_f1" class="java.lang.String"/> <field name="cl2_f2" class="java.lang.String"/> **<field name="cl1_ob1" class="Class2"/>** </subDataset> For the third parameter, I would like to mention one of its fields. For example: cl1_ob1.cl1_f1 . How can I accomplish this? In the Jasper report design
