I have the following class that I take as input in my Resource
#JsonIgnoreProperties(ignoreUnknown = false)
public class InputRequest {
#NotEmpty
private List<String> names;
private DateTime startDate;
private DateTime endDate;
#ValidationMethod(message="startDate should be less than endDate")
public boolean isValidDates() {
return startDate.isBefore(endDate);
}
#ValidationMethod(message = "one of the names is not valid")
public boolean isValidNames() {
//do something
}
public List<String> getNames() {
return names;
}
public void setNames(List<String> names) {
this.names = names;
}
public DateTime getStartDate() {
return startDate;
}
public void setStartDate(DateTime startDate) {
this.startDate = startDate;
}
public DateTime getEndDate() {
return endDate;
}
public void setEndDate(DateTime endDate) {
this.endDate = endDate;
}
}
The resource class is as follows
public Response getData(#Auth String userId, #Valid InputRequest request) {
However, the following input is not causing any exceptions
{"names":["somename"],"startDate":1427155200000,"endDate":1427846400000, "x":"a"}
Can someone tell me what I am doing wrong here?
EDIT: Also if I send the following instead, its passing through
{"names":["somename"],"startDate":1427155200000}
I want it to fail if something field is missing
bootstrap.getObjectMapperFactory().enable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
worked for me

I have a service, that gets an xml/json string, tries to read it as an pojo, then returns it. Then, I want to show the result in thymeleaf. I did that successfully, but - in the model I have validation annotations, but if I submit invalid information it accepts the value, although I validated the method. Here is my code:

convertFrom, String text, Model model){
if("json".equals(convertFrom)){

model.addAttribute("result", newBook);
return "converted";
}else if("xml".equals(convertFrom)){
Book newBook = readXML.read(text);
model.addAttribute("result", newBook);
return "converted";
}
return "read";
}
#GetMapping("/print")

Where is my problem???
Thank you!
I have a case where I need to execute an insert statement via createNativeQuery. I have an entity list I'm looping through in order to set the properties accordingly from another bean class, and then persist that data to the oracle database.
The problem I am facing is persisting the data that is part of the embeddedId (item, loc, weekstart, type, forecastId, insertTS). I need to persist that data for the new records to be inserted into the database. When I try to set the values from the POJO bean to my set method for the properties of my entity bean, nothing happens. Below is my code for setting the values of the properties from the POJO bean to my entity bean, along with my persistence method and the insert query being executed:
Validation class where validation occurs beforehand (missing to get the point) that includes the setting of my entity properties from the POJO bean:
List <InsertPromoData> insertPromos = new ArrayList<InsertPromoData>();
promo.forEach(record -> {
if (record.getErrorList().size() == 0) {
rowsSuccessful++;
Util.writeSuccessToFile(templateCd, successFile, record, successFields);
try {
InsertPromoData insertData = new InsertPromoData();
insertData.getId().setItem(record.getItem());
insertData.getId().setLoc(record.getLoc());
insertData.getId().setWeekStart(record.getWeek_Start_Date());
insertData.setNumberOfWeeks(record.getNumber_Of_Weeks());
insertData.getId().setType(record.getType());
insertData.getId().setForecastId(record.getForecast_ID());
insertData.setQty(record.getUnits());
insertPromos.add(insertData);
}
catch (Exception e) {
logger.error("Error with setting insertPromolist from promo list values and the error is " + e.getMessage());
}
}
else {
if (rowsFailure == 0) {
Util.writeHeaderToFile(templateCd, errorFile);
}
rowsFailure++;
Util.writeErrorToFile(templateCd, errorFile, record, record.getErrorList());
}
});
errorFile.close();
successFile.close();
OracleImpl.insertPromoData(insertPromos);
POJO bean (promo is the variable representing this list of beans in validation class above):
public class PromoBean extends ErrorListBean
{
public String Item;
public String Loc;
public String Week_Start_Date;
public String Units;
public String Forecast_ID;

em.clear();
em.close();

logger.debug("Execution of method insertPromoData in Dao ended");
}
Query in properties file:
insertPromoUploadData = INSERT INTO {h-schema}U_USER_PROMO (ITEM, LOC, WK_START, NUMBER_OF_WEEKS, TYPE, FCSTID, QTY, U_TIMESTAMP) VALUES (:item, :location, TO_DATE(:wkStart,'MM DD YYYY'), :numberOfWeeks, :type, :fcstId, :quantity, SYSDATE)
My list size from my DAO class is returning as 0 once I begin the transaction and not sure why it is empty. Is there a reason that it is empty? I'm trying to persist each of the fields to the database (including the composite key fields) via insert query. Any help appreciated.
After looking into this for hours, I finally came to the conclusion that the simplest way to executeUpdate() without running into issues due to my current #EmbeddedId/#Embeddable logic was to change it to use #IdClass for my composite PK class, and annotate the fields from the PK in my entity with #Id. This allowed my data to be persisted to the database. Another slight difference was adding the insertTS in my entity class and annotating with #Id and generating getters/setters. This was necessary for JPA to recognize all the properties being referenced that I am wanting to persist, though I am persisting insertTS using SYSDATE function from the oracle DB instead of utilizing the get/set methods and setting to the current time from the java side.
I am sure there is a way to use #EmbeddedId/#Embeddable logic and be able to persist the fields that are part of the EmbeddedId, however, this I found to be a more simplistic way of doing it without further complexity in the code.
I have a query to My SQL database and I use Spring Boot to return it to Json format.
My problem is it only return value without key like:
[
[
"kermit",
6
]
]
I want it return like:
[
[
"name":"kermit",
"count" :6
]
]
I tried add Jackson Annotation jar file to project and use #JsonProperty in my entity model class:
#Entity
#Table(name = "act_id_membership", schema = "activiti", catalog = "")
#IdClass(ActIdMembershipEntityPK.class)
public class ActIdMembershipEntity {
#JsonProperty("name")
private String userId;
#JsonProperty("group")
private String groupId;
#Id
#Column(name = "USER_ID_")
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
#Id
#Column(name = "GROUP_ID_")
public String getGroupId() {
return groupId;
}
public void setGroupId(String groupId) {
this.groupId = groupId;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
ActIdMembershipEntity that = (ActIdMembershipEntity) o;
return Objects.equals(userId, that.userId) &&
Objects.equals(groupId, that.groupId);
}
#Override
public int hashCode() {
return Objects.hash(userId, groupId);
}
}
But it still return without key. What I should do now? Please help me!
Thank you very much!
First, I'm agree with guy who commented that is not valid JSON format. You can see examples here https://json.org/example.html
Second, You need to create an object JSON which has fields needed for example:
public class UserStat es implements Serializable {
private String name;
private long count;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public long getCount() {
return count;
}
public void setCount(long count) {
this.count = count;
}
}
And in your custom query. Based your return looks like on this way:
#Query("SELECT u.name, count(u) FROM User u")
public List<UserStat> findUserStat() ;
I want to sort Descending by lastChange property, the List of items from mongo.
RequestRepository interface:
public interface RequestRepository extends MongoRepository<Request, String> {
List<Request> findByUser(String id);
}
Request.java:
#Document(collection = "Requests")
public class Request {
#Id
private String id;
private String user;
private String username;
private String requestTitle;
private String requestMessage;
private boolean read;
private Date lastChange;
private Date requestDate;
private boolean isActiveRequest;
private boolean isPremiumRequest; //paid request
public Request() {}
public Request(
String user,
String requestTitle,
String requestMessage,
boolean read,
Date lastChange,
Date requestDate,
boolean isActiveRequest) {
this.user = user;
this.requestTitle = requestTitle;
this.requestMessage = requestMessage;
this.read = read;
this.lastChange = lastChange;
this.requestDate = requestDate;
this.isActiveRequest = isActiveRequest;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getRequestTitle() {
return requestTitle;
}
public void setRequestTitle(String requestTitle) {
this.requestTitle = requestTitle;
}
public String getRequestMessage() {
return requestMessage;
}
public void setRequestMessage(String requestMessage) {
this.requestMessage = requestMessage;
}
public boolean isRead() {
return read;
}
public void setRead(boolean read) {
this.read = read;
}
public Date getLastChange() {
return lastChange;
}
public void setLastChange(Date lastChange) {
this.lastChange = lastChange;
}
public Date getRequestDate() {
return requestDate;
}
public void setRequestDate(Date requestDate) {
this.requestDate = requestDate;
}
public boolean isActiveRequest() {
return isActiveRequest;
}
public void setActiveRequest(boolean activeRequest) {
isActiveRequest = activeRequest;
}
public boolean isPremiumRequest() {
return isPremiumRequest;
}
public void setPremiumRequest(boolean premiumRequest) {
isPremiumRequest = premiumRequest;
}
}
In my code I have the following list:
List<Request> = RequestRepository.findByUser(userObj.getId());
I want to have the data from RequestRepository.findByUser(userObj.getId()); sorted DESCENDING by the property lastChange.
I have searched on StackOverflow, and found the following method to sort:
List<Request> findAllByOrderByUpdatedAtDesc();
but this does not work if I search by User.
What is the solution to search by User id and to sort by lastChange?
Thank you!
This should do it.
List<Request> findByUserOrderByLastChangeDesc(String user);
Update your question with proper details.
I know I've already asked about Lab 14, but I've edited my code a lot since then. I think its a lot better, but I think something is still wrong. Is it with the setters? I looked on another forum that says I'm making progress, but while they get back to me, I need someone to help edit my syntax. If what I'm doing wrong is my setters, I'll be fine but tell me that please.
I really really really really want to get this program working so that I can move on since I'm behind in class. Yes, this is Java.
Here's my code:
public class StreetAddress
{
public String street;
public String city;
public String state;
public String zip;
public StreetAddress(String findStreet, String findCity,String findState,String findZIP) {
street = findStreet;
city = findCity;
state = findState;
zip = findZIP;
}
public String getStreet() {
return street;
}
public void makeStreet(String street) {
this.street = street;
}
public String getcity() {
return city;
}
public void makeCity(String city) {
this.city = city;
}
public String getState() {
return state;
}
public void makeState(String state) {
this.state = state;
}
public String getZip() {
return zip;
public void makeZip(String zip) {
this.zip = zip;
}
}
}
}
Thanks.
You can do it in any of the 2 ways.
Using parameterized constructor
class StreetAddress
{
public String street;
public String city;
public String state;
public String zip;
public StreetAddress(String findStreet, String findCity,String findState,String findZIP){
street = findStreet;
city = findCity;
state = findState;
zip = findZIP;
}
public String getStreet() {
return street;
}
public String getcity() {
return city;
}
public String getState(){
return state;
}
public String getZip() {
return zip;
}
}
and pass values from main function during calling of StreetAddress object.
by using Default constructor,
class StreetAddress
{
public String street;
public String city;
public String state;
public String zip;
public String getStreet() {
return street;
}
public void makeStreet(String street){
this.street = street;
}
public String getcity() {
return city;
}
public void makeCity(String city){
this.city = city;
}
public String getState(){
return state;
}
public void makeState(String state){
this.state = state;
}
public String getZip() {
return zip;
}
}
and pass values directly by calling functions makeZip(anyString);
You have three closing braces at the end! It should be only one and you forgot to write closing brace for your getZip Method. One more problem with your code is that you have defined your instance variables public which doesn't make any sense when you are implementing accessors for them. As a result, you'd better to make them private so you also follow the encapsulation topic of OOP. One other problem with your naming is your setters' naming convention. It is a common convention in Java programming that you name your getter as get[InstanceVatiableName] ie: getStreet and your setter like: set[InstanceVariableName] ie: setStreet.
I have corrected mentioned problems for your code in below:
public class StreetAddress
{
private String street;
private String city;
private String state;
private String zip;
public StreetAddress(String findStreet, String findCity, String findState, String findZIP) {
street = findStreet;
city = findCity;
state = findState;
zip = findZIP;
}
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 getZip() {
return zip;
}
public void setZip(String zip) {
this.zip = zip;
}
}
