My springboot application has a #RestController which takes a POJO class as parameter.
#GetMapping(path="/")
public void sayHello(Person person) {
System.out.println(person);
}
and here's the definition of Person class which is just a POJO.
public class Person {
private String firstName;
private String lastName;
private int age;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
#Override
public String toString() {
return "Person [firstName=" + firstName + ", lastName=" + lastName + ", age=" + age + "]";
}
}
This is how springdoc-ui interprets it for showing parameters in UI.
I did not use #RequestBody in the controller yet springdoc assumes the input to be in the form of JSON body. I intend it to be as query parameters as below
Interestingly if I change the swagger implementation to springfox, each fields of the POJO is interpreted as individual parameters in the UI by default. The last screenshot was taken using springfox implemntation. How do I get the same behavior with springdoc?
Using #ParameterObject fixes this.
#GetMapping(path="/")
public void sayHello(#ParameterObject Person person) {
System.out.println(person);
}

I'm writing a dto class containing the information of a user
public class User {
private String firstName;
private String lastName;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
I'd receive this JSON object if I do GET api/v1/user/1
{
firstName: John,
lastName: Kennedy
}
But when the firstName and the lastName are null, I want to receive an empty object like:
{}
How would you do technically on Spring Boot in order to receive such empty object in Json format?
Thank you in advance
You could try to annotate your class with:
#JsonInclude(Include.NON_NULL)
If you want an empty object { } and empty request is not valid for you, you can create an auxiliar class called EmptyObject or something similar:
#JsonSerialize
public class EmptyObject {
}
And into your controller:
return user.getFirstName() == null && user.getLastName() == null ?
ResponseEntity.ok(new EmptyObject()) : ResponseEntity.ok(user);
I need to filter condition by firstname and lastname in the List of names present in either official or unOfficial names List and return List of EmployeeDetails.
Below are the pojo classes
public class EmployeeDetails {
private NameDetails nameDetails;
public NameDetails getNameDetails() {
return nameDetails;
}
public void setNameDetails(NameDetails nameDetails) {
this.nameDetails = nameDetails;
}
}
public class NameDetails {
private List<Name> officalName;
private List<Name> unOfficialName;
public List<Name> getOfficalName() {
return officalName;
}
public void setOfficalName(List<Name> offiicalName) {
this.officalName = offiicalName;
}
public List<Name> getUnOfficialName() {
return unOfficialName;
}
public void setUnOfficialName(List<Name> unOfficialName) {
this.unOfficialName = unOfficialName;
}
}
public class Name {
private String firstName;
private String lastName;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
I tried for filtering with list of officialNames and it is working fine,but I also want to filter names present in unOfficial Names also.(OR Condition)
return employeeDetailList.stream().filter(employeeDetails->(employeeDetails.getNameDetails().getOffiicalName()).stream()
.anyMatch(name-> (null!=name) && (firstName).equals(name.getFirstName()) && (lastName).equals(name.getLastName())))
.collect(Collectors.toList());
Help me to solve the issue.Thanks
If you can't override equals/hashCode (if you could there would be a faster way), then:
employeeDetailList
.stream()
.filter(x -> Stream.concat(
x.getNameDetails().getOfficalName().stream(),
x.getNameDetails().getUnOfficialName().stream()
)
.anyMatch(y -> Objects.equals(y.getFirstName(), firstName) &&
Objects.equals(y.getLastName(), lastName)))
.collect(Collectors.toList());
Just add the OR condition:
return employeeDetailList.stream().filter(employeeDetails->
((employeeDetails.getNameDetails().getOffiicalName()).stream().anyMatch(name-> (null!=name) && (firstName).equals(name.getFirstName()) && (lastName).equals(name.getLastName()))))
|| ((employeeDetails.getNameDetails().getUnOfficialName()).stream().anyMatch(name-> (null!=name) && (firstName).equals(name.getFirstName()) && (lastName).equals(name.getLastName()))))
.collect(Collectors.toList());
Given this class written in the Java 8 style, I wanted to see if I dont need to call the stream api twice :
import java.util.*;
public class Foo {
public static void main(String... args) {
List<Person> persons = new ArrayList<>();
init(persons, Person::new, "John", "Doe");
persons.stream()
.map(Person::getFirstName)
.forEach(System.out::println);
persons.stream()
.map(Person::getLastName)
.forEach(System.out::println);
}
#FunctionalInterface
interface PersonFactory {
Person create(String firstName, String lastName);
}
private static void init(List<Person> persons, PersonFactory factory, String fn, String ln) {
persons.add(factory.create(fn, ln));
}
}
class Person {
private final String firstName;
private final String lastName;
public Person(String fName, String lName) {
this.firstName = fName;
this.lastName = lName;
}
public String getFirstName() {return this.firstName;}
public String getLastName() {return this.lastName;}
}
I wanted to see if I could instead stream the "persons" List in one go.
Any suggestions ?
If you don't need to transform object to another, you can try this
persons.forEach(i -> System.out.println(i.getFirstName() + " " + i.getLastName()));
i think it could be helpfull for you using Map
Map<String, String> mapp = persons.stream().collect(HashMap::new,
(m, c) ->{
m.put(c.getFirstname(), "");
m.put(c.getLastname(), "");
},HashMap::putAll);
System.out.println(mapp.keySet().toString());
I have written a program to display some details entered in one form in another.Like I have a UserRegisteration.jsp where I am entering few details and UserAccount.jsp which has to display some of the entered details.I have created a model object UserDetails which has all the details of a particular code.
When I am running the project I am getting the propertynotfound exception.I have checked everything and couldn't find the reason behind it.I have the getters and setters methods in my model class.And using auto-binding feature using #modelattribute.Kindly let me know if I missed any code.

None of the related posts helped me in resolving this issue, so I have posted this one.
The problem is cause by the way you are accessing your property in jsp,
${user.UserName}
should instead be
${user.userName}
Same for the other expressions, you should lower case the first letter.
Behind the scenes the UserDetails is introspected and a map of properties is created, but the keys are based on your getter/setter methods, so lowercased (userName, firstName, lastName). In your JSP EL you're passing the key, and it is not matching any property on account of case difference
Your instance variables do not respect the java naming principles. Java variables should start with lower letter and use camel case capitalization.
Ex: userName, firstName, lastName,
and the corresponding getters would be getUserName(), getFirstName(), getLastName().
If you have the instance variable defined like this the jsp accessors will be obtained by stripping the get (or is, if the method returns a boolean) suffix and lower the first letter of the remaining method name: ${user.userName}, ${user.firstName}, ${user.lastName}.
i have this query in my code. i am trying to isert a image into table in the last column(blob). it is showing invalid hex number. can anybody help me out of this?

System.out.println(num);
}
}
any kind of response is appreciated in advance.
This error:
invalid hex number ora-01465
means that your not sending an Hexa.
Solution:
Please try to convert InputStream to Hexa before insert image.
