Apex parse values from Json string into custom field - apex

Im trying to parse trough json string and return values into custom meta data type field on Case. I have created the custom metadata type already, example:
<label>Jordfeil.Casefield</label>
<protected>false</protected>
<values>
<field>CaseField__c</field>
<value xsi:type="xsd:string">Casefield</value>
</values>
<values>
<field>Context__c</field>
<value xsi:type="xsd:string">JORDFEIL</value>
</values>
<values>
<field>JsonField__c</field>
<value xsi:type="xsd:string">key1</value>
</values>
</CustomMetadata>
Json String :
{
"operation": "get-id",
"payload": {
"ApplicationContext": {
"Context": "JORDFEIL",
"SenderId": "xxx",
"subContext": ""
},
"supportIssue": {
"InfoFields": [
{
"Key": "key1",
"Value": "value1"
},
{
"Key": "key2",
"Value": "value2"
},
{
"Key": "key3",
"Value": "value3"
}
],
}
},
"type": "~:CustomerInquiry",
}
My Wrapper class:
public class WebskjemaModel {
public class ApplicationContext {
public String Context;
public String SenderId;
public String subContext;
}
public String operation;
public Payload payload;
public String type;
public class InfoFields {
public String Key;
public String Value;
}
public class Payload {
public ApplicationContext ApplicationContext;
public SupportIssue supportIssue;
}
public class SupportIssue {
public List<InfoFields> InfoFields;
public String assignId;
public String businessObjectType;
public String comment;
public String contactDate;
public String contactName;
public String customerName;
public String customerNo;
public String docClass;
public String format;
public String objectDescription;
public String objectId;
public String subject;
}
public static WebskjemaModel parse(String json) {
return (WebskjemaModel) System.JSON.deserialize(json, WebskjemaModel.class);
}
}
The json string is stored a field in Case called WebskjemaBlob__c.
Below is my class:
public with sharing class WebskjemaCaseCreator {
Map<String, Case> Webskjemastring = new Map<String, Case>();
private Map<Id, Case> cases { get; set; }
private Map<Id, WebskjemaModel> webskjemaModels = new Map<Id, WebskjemaModel>();
public WebskjemaCaseCreator(Map<Id, Case> cases) {
this.cases = cases;
deserializeJson();
mapFields();
}
private void deserializeJson() {
for (Id caseId : cases.keySet()) {
Case c = cases.get(caseId);
WebskjemaModel model = WebskjemaModel.parse(c.Webskjemablob__c);
webskjemaModels.put(caseId, model);
}
}
private void mapFields() {
for (Id caseId : cases.keySet()) {
Case c = cases.get(caseId);
WebskjemaModel model = webskjemaModels.get(caseId);
}
}
private void mapFieldsForSingleCase(Case c, WebskjemaModel model) {
// TODO: Find WebskjemaModel inforfields and loop
// for (list of infofields for this model only){
// TODO: call method mapInfoField
// }
}
private void mapInfoField(Case c, String context, String infoFieldKey, String infoFieldValue) {
// TODO: Find Case field from custom meta data type mapping, based on context and infoFielfKey
// TODO: Put value from inforFieldValue into Case field
}
}
My question is how you get the key value pair from infofields and update the case fields based on the custom meta data type mapping?

Cannot deserialize instance of <Object> out of START_ARRAY token - webClient

I am writing a simple get method using webclient to fetch property information. But then, I am getting below's error response message:
{
"timestamp": "2019-02-25T06:57:03.487+0000",
"path": "/modernmsg/getentity",
"status": 500,
"error": "Internal Server Error",
"message": "JSON decoding error: Cannot deserialize instance of `com.reputation.api.modernmsg.model.Entity` out of START_ARRAY token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `com.reputation.api.modernmsg.model.Entity` out of START_ARRAY token\n at [Source: UNKNOWN; line: -1, column: -1]"
}
Actual json response is:
[
{
"name": "Point Breeze",
"street": "488 Lemont Dr",
"city": "Nashville",
"state": "TN",
"postal_code": "37216",
"slug": "point-breeze"
}
]
Below is the method in my controller class to fetch property:
#RequestMapping(method = RequestMethod.GET, value = "/getentity")
public Mono<Entity> getEntity(#RequestParam("token") String token, #RequestParam("name") String name) {
return service.fetchEntity(token, name);
}
And my fetchEntity method is:
public Mono<Entity> fetchEntity(String token, String name) {
String url = host + version + entityEndpoint + "?token=" + token + "&name=" + name;
return webClient.get().uri(url).retrieve().bodyToMono(Entity.class);
}
Below is my Entity model:
package com.reputation.api.modernmsg.model;
import java.util.List;
public class Entity {
private List<ModernMsgEntity> modernMsgEntity;
public List<ModernMsgEntity> getModernMsgEntity() {
return modernMsgEntity;
}
public void setModernMsgEntity(List<ModernMsgEntity> modernMsgEntity) {
this.modernMsgEntity = modernMsgEntity;
}
}
ModernMsgEntity model is:
package com.reputation.api.modernmsg.model;
public class ModernMsgEntity {
private String name;
private String street;
private String city;
private String state;
private String postal_code;
private String slug;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getStreet() {
return street;
}
public void setStreet(String street) {
this.street = street;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
public String getPostal_code() {
return postal_code;
}
public void setPostal_code(String postal_code) {
this.postal_code = postal_code;
}
public String getSlug() {
return slug;
}
public void setSlug(String slug) {
this.slug = slug;
}
}
Let me know if you need more information.
This is more of a JSON deserialization problem. Looking at your entity class, you're setting things up to expect a JSON response like:
{
"modernMsgEntity": [
{
"name": "Point Breeze",
"street": "488 Lemont Dr",
"city": "Nashville",
"state": "TN",
"postal_code": "37216",
"slug": "point-breeze"
}
]
}
If you want Jackson to deserialize an array of objects directly, you have to tell it so:
Flux<ModernMsgEntity> messages = webClient.get().uri(url).retrieve().bodyToFlux(ModernMsgEntity.class);

SpringBoot java Collection annotation for Swagger

I have a problem with annotations and generating documentation (spring-boot, springfox-swagger2).
What should be a proper annotation for String Collection in my TechnologyDTO?
Does swagger support java.util.Collection?
After generation I have:
Model schema:
{
"technologies": {},
"userGUID": "string"
}
Model:
TechnologyDTO {
technologies (Collection«string»): User main technology names,
userGUID (string): User guid
}
Collection«string» {
}
My TechnologyDTO:
public class TechnologyDTO {
private final String userGUID;
private final Collection<String> technologies;
public TechnologyDTO(String userGUID, Collection<String> technologies) {
this.userGUID = userGUID;
this.technologies = technologies;
}
#ApiModelProperty(notes = "User guid", dataType="string", required = true)
public String getUserGUID() {
return userGUID;
}
#ApiModelProperty(notes = "User main technology names", required = true)
public Collection<String> getTechnologies() {
return technologies;
}
public static TechnologyDTO createEmptyDTO() {
return new TechnologyDTO(null, null);
}
}

Error in annoting camel swagger Rest Service

I have created a rest Service using Apache Camel Swagger component. The rest service works fine but the request and response schema is not what i intended of.
The schema that i am trying to create is :
{
"GetStudentData": [
{
"RollNumber": "1",
"Name": "ABC",
"ClassName": "VII",
"Grade": "A"
}]
}
For this i have created a model as:
import java.util.List;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;
#XmlRootElement(name = "GetStudentData")
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name="", propOrder={"studentInfo"})
public class StudentInfoWrapper {
#XmlElement(required=true)
private List<Student> studentInfo;
private double visiteddate;
public double getVisiteddate() {
return visiteddate;
}
public void setVisiteddate(double visiteddate) {
this.visiteddate = visiteddate;
}
public List<Student> getStudentInfo() {
return studentInfo;
}
public void setStudentInfo(List<Student> studentInfo) {
studentInfo = studentInfo;
}
}
And my student class is:
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlType;
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name="", propOrder={"RollNumber", "Name", "ClassName", "Grade"})
public class Student {
private String RollNumber;
private String Name;
private String ClassName;
private String Grade;
public String getRollNumber() {
return RollNumber;
}
public void setRollNumber(String rollNumber) {
RollNumber = rollNumber;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public String getClassName() {
return ClassName;
}
public void setClassName(String className) {
ClassName = className;
}
public String getGrade() {
return Grade;
}
public void setGrade(String grade) {
Grade = grade;
}
}
So when i load the above service into the swaggerUI it doesn't show the schema that i want.
How can i i get the desired schema. Looking forward to your answers.
Thanks in advance.

cannot resolve symbol (class declaration)

I created a class like this :
namespace Web.Models
{
public class TimeLineStep
{
public string Code { get; set; }
public string Title;
public string Description;
public string Url;
public string Status;
public string Category;
}
}
And I use this class in a model like this :
namespace Web.Models
{
public class TimelineList
{
private List<TimelineStep> _steps;
public List<TimelineStep> Steps
{
get
{
return this._steps ?? (this._steps = new List<TimelineStep>());
}
set
{
this._steps = value;
}
}
Both are under same namespace but the class TimeLineStep is underlined with red and it says cannot resolve symbol 'TimeLineStep'

In Spring-mvc the attribute names in view have to always match the property names in model?

In the http request body, the way password string is passed is "pass=1111", however in the bean the way password is defined is ''private String password". Is there a way I can use annotation to handle the difference or I have to always match names?
The Http request is like this
curl -H "Accept:text/html" -H "Content-Type application/x-www-form-urlencoded" -d 'email=test%40gmail.com&pass=1111&passconfirm=1111&name=x+y' "http://localhost:8080/project/register"
Handler method is
#RequestMapping(method = RequestMethod.POST, headers = "content-type=application/x-www-form-urlencoded")
public String register(#ModelAttribute UserAccountBean account) ...
UserAccountBean is
public class UserAccountBean2 {
#NotNull
#Size(min = 1, max = 25)
private String name;
#NotNull
#Size(min = 4, max = 8)
private String password;
#NotNull
private String email;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword()
{
return password;
}
public void setPassword(String password)
{
this.password = password;
}
public String toString() {
return new ToStringCreator(this).append("name", name).append("password", password).toString();
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
Use #RequestParam annotation in #InitBinder annotated method, and set the desired value manually.
UserController
#InitBinder(value="user")
public void bind(WebDataBinder dataBinder, WebRequest webRequest, #RequestParam(value="pass", required=false) String password) {
User user = (User) dataBinder.getTarget();
user.setPassword(password);
}
Is there a way I can use annotation to
handle the difference or I have to
always match names?
AFAIK there is no ready-made annotation in Spring MVC that can resolve your problem; you need custom setup to handle the situation.

You can also have a public static void bindWebParameters(...) method in some helper class; so you don't have to extend the AbstractController every time.
You can achieve it with this:
#RequestMapping(method = RequestMethod.POST, headers = "content-type=application/x-www-form-urlencoded")
public String register(#ModelAttribute("userAccountBean") UserAccountBean account) ...
#ModelAttribute("userAccountBean")
public UserAccountBean getUserAccountBean(HttpServletRequest req) {
UserAccountBean uab = new UserAccountBean();
uab.setPassword(req.getParameter("pass"));
return uab;
}
There is no annotation based solution in 3.0.
Just provide additional getPass() setPass(String pass) method and you should be set.
