Error creating bean with name 'orderController'

Error creating bean with name 'orderController' - java

I am studying Spring Boot and I want to create a Rest Controller, and using a sql database, but there is a problem when I start the project :
Error:

I would be grateful for any help, thanks in advance

If you check the error, you can see that it comes from there:
List<Order> findByTitleContainingOrContentContaining(String item);
and if you read more closely to the error, you will see:
No property title found for type Order!;
inside here:
Caused by: org.springframework.data.repository.query.QueryCreationException: Could not create query for public abstract java.util.List com.test.project.OrderRepository.findByTitleContainingOrContentContaining(java.lang.String)! Reason: Failed to create query for method public abstract java.util.List com.test.project.OrderRepository.findByTitleContainingOrContentContaining(java.lang.String)! No property title found for type Order!; nested exception is java.lang.IllegalArgumentException: Failed to create query for method public abstract java.util.List com.test.project.OrderRepository.findByTitleContainingOrContentContaining(java.lang.String)! No property title found for type Order!
Infact, if you check your model, there is no title property

JAX-RS gives status code 500 for GET operation for XML type response

I have just begun to learn RESTful services and this is the issue I have been facing recently.
When I run the application to GET an XML type response, I get status code 500 and I don't see any stack trace for this as well. Am I missing anything in the dependency list ? Please help me figure this.
Here is the entity class :
import java.util.Date;
import jakarta.xml.bind.annotation.XmlRootElement;
#XmlRootElement
public class Message {
private int id;
private String message;
private String author;
private Date date;
public Message() {}
public Message(int id, String message, String author) {
super();
this.id = id;
this.message = message;
this.author = author;
this.date = new Date();
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
#Override
public String toString() {
return "Message [id=" + id + ", message=" + message + ", author=" + author + ", date=" + date + "]";
}
}
And then I have my service class : MessageService.java :
import java.util.ArrayList;
import java.util.List;
import org.aravind.restful.messenger.model.Message;
public class MessageService {
public List<Message> getMessages()
{
Message m1 = new Message(1,"Hello World!","aravind");
Message m2 = new Message(2,"First step towards the goal!","aravind");
List <Message> messageList = new ArrayList<Message>();
messageList.add(m1);
messageList.add(m2);
return messageList;
}
}
And then I have the resource class : MessengerResouce.java
package org.aravind.restful.messenger.resources;
import java.util.List;
import org.aravind.restful.messenger.model.Message;
import org.aravind.restful.messenger.service.MessageService;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;
#Path("/messages")
public class MessengerResource {
#GET
#Produces(MediaType.APPLICATION_XML)
public List<Message> getMessages()
{
MessageService msgService = new MessageService();
return msgService.getMessages();
}
}
And here is how my pom.xml looks :
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Please help me figure this out. Thanks.

The link Sam suggested answers your question. You have to wrap your response as a GenericEntity. Here is the documentation from the Response class:
"It is the callers responsibility to wrap the actual entity with GenericEntity if preservation of its generic type is required."
So your code should look something like this:
#GET
#Produces(MediaType.APPLICATION_XML)
public Response getMessages()
{
MessageService msgService = new MessageService();
return Response.status(Status.OK)
.entity(new GenericEntity<>(msgService.getMessages(), List.class))
.build(); ;
}

Spring boot ERROR "Field trepository in TrainerController required a bean of type TrainerRepo that could not be found." ."

Im making a Spring boot project and when running it says:
"Field trepository in com.example.trainerplanner.trainerController.TrainerController required a bean of type 'com.example.trainerplanner.model.domain.TrainerRepository' that could not be found."
I already cleaned the .m2 directory and tried to add/delete many different dependencies.

This is the TrainerModel class

Getting the error : Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException

I am new to spring and I wanted to communicate with mongodb via spring. I tried and tested the following code on SPRING TOOL SUITE but I am getting the following error:
Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [hello.PersonRepository] is defined
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:371)
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:331)
at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:968)
at hello.Runhere.main(Runhere.java:19)
Kindly tell me where is the problem.
Here is Person.java class
package hello;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
#Document
public class Person {
#Id
private String personId;
private String name;
private int age;
public Person(String name, int age) {
this.name = name;
this.age = age;
}
public String getPersonId() {
return personId;
}
public void setPersonId(final String personId) {
this.personId = personId;
}
public String getName() {
return name;
}
public void setName(final String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(final int age) {
this.age = age;
}
#Override
public String toString() {
return "Person [id=" + personId + ", name=" + name + ", age=" + age
+ "]";
}
}
Here is my PersonRepository.java file
package hello;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.stereotype.Repository;
#Repository
public class PersonRepository {
#Autowired
MongoTemplate mongoTemplate;
public void countUnderAge() {
List<Person> results = null;
Query query = new Query();
Criteria criteria = new Criteria();
criteria = criteria.and("age").lte(21);
query.addCriteria(criteria);
results = mongoTemplate.find(query, Person.class);
System.out.println(results.size());
}
public void countAllPersons() {
List<Person> results = mongoTemplate.findAll(Person.class);
System.out.println("The total number of players " + results.size());
}
public void insertPersonWithNameAayushAndRandomAge() {
double age = Math.ceil(Math.random() * 100);
Person p = new Person("Aayush", (int) age);
mongoTemplate.insert(p);
}
public void createPersonCollection() {
if (!mongoTemplate.collectionExists(Person.class)) {
mongoTemplate.createCollection(Person.class);
}
}
public void dropPersonCollection() {
if (mongoTemplate.collectionExists(Person.class)) {
mongoTemplate.dropCollection(Person.class);
}
}
}
Here is my springconfig.java file:
package hello;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;
import com.mongodb.Mongo;
#Configuration
#EnableMongoRepositories
#Import(RepositoryRestMvcConfiguration.class)
#EnableAutoConfiguration
public class springconfig extends AbstractMongoConfiguration {
#Override
protected String getDatabaseName() {
return "demo";
}
#SuppressWarnings("deprecation")
#Override
public Mongo mongo() throws Exception {
return new Mongo();
}
}
Here is my class which contains the main method :
package hello;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
public class Runhere {
public static void main(String[] args) {
#SuppressWarnings("resource")
ApplicationContext context = new AnnotationConfigApplicationContext(springconfig.class);
PersonRepository personRepository = context.getBean(PersonRepository.class);
personRepository.dropPersonCollection();
personRepository.createPersonCollection();
for (int i = 0; i < 10000; i++) {
personRepository.insertPersonWithNameAayushAndRandomAge();
}
personRepository.countAllPersons();
personRepository.countUnderAge();
}
}

try to add bean in the application config.xml
<mvc:resources mapping="" location="" />
<bean id="PersonRepository" class="(complete package path)hello.PersonRepository" />

SpringBoot - In hope it will help any SpringBoot developer
This error mostly hits when the bean you are calling from another package.
Specifically for Spring boot, you can try an annotation for it, to scan the component you want to get bean of it.
#ComponentScan("your package")
place the #Componentscan annotation in the main class where you are getting the bean.
Example
#ComponentScan("com.spring.crud.controller")
public class SpringCrudApplication {
public static void main(String[] args) {
ApplicationContext context = SpringApplication.run(SpringCrudApplication.class, args);
HomeController bean1 = context.getBean(HomeController.class);
System.out.println(bean1.HomePage());
}
}
so, in the above example I am taking controller bean which I created in the package of com.spring.crud.controller
if you are interested in explanation see this article:
