springBoot and hibernate 404 not found

I train with springboot and a mariadb database. When I test for data recovery, I get this message in postman:
{
"timestamp": "2022-03-03T13:53:18.609+00:00",
"status": 404,
"error": "Not Found",
"path": "/user/all"
}
. I tried several tutorials in copy paste and I always have the same message. I will also put the message that is in the console. Thank you in advance for your help.

Every thing on the controller class is implemented properly and there is definitely no need for other layers implementation to share, you probably use SpringBootServletInitializer, in the main class add the #EnableWebMvc annotation and override SpringApplicationBuilder method as
#SpringBootApplication
#EnableWebMvc
public class Application extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
Otherwise if you use SpringApplication to sun the project make sure the main class annotated with #SpringBootApplication and be some thing like
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
And final thing check the presence of spring boot starter web dependency in you pom file
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
If you do not use spring boot parent do not forget to add the proper version to web starter artifact.

sessionRepository in com.sparsh.conferencedemo.controllers.SessionController required a bean of type that could not be found

I was trying to create a simple CRUD spring boot application after watching an online course. But when i run the application it shown an error "Field speakerRepository in com.sparsh.conferencedemo.controllers.SpeakerController required a bean of type 'com.sparsh.conferencedemo.repositories.SpeakerRepository' that could not be found." I don't understand what I am doing wrong. Also I am new to the spring boot. So any help please. I am posting my code below.
This is my SessionController
package com.sparsh.conferencedemo.controllers;
import com.sparsh.conferencedemo.models.Session;
import com.sparsh.conferencedemo.repositories.SessionRepository;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;

#RestController
#RequestMapping("/api/v1/sessions")
public class SessionController {
#Autowired
private SessionRepository sessionRepository;
#GetMapping
private List<Session> list(){
return sessionRepository.findAll();
}
#GetMapping
#RequestMapping("{id}")
private Session get(#PathVariable Long id){
return sessionRepository.getOne(id);
}
#PostMapping
#ResponseStatus(HttpStatus.CREATED)
public Session create(#RequestBody final Session session){
return sessionRepository.saveAndFlush(session);
}
#RequestMapping(value="{id}", method = RequestMethod.DELETE)
public void delete(#PathVariable Long id){
sessionRepository.
}
#RequestMapping(value="{id}", method = RequestMethod.PUT)
public Session update(#PathVariable Long id, #RequestBody Session session){
Session existingSesseion=sessionRepository.getOne(id);
BeanUtils.copyProperties(session, existingSesseion, "session_id");
return sessionRepository.saveAndFlush(existingSesseion);
}
}
This is my SessionRepository interface
package com.sparsh.conferencedemo.repositories;
import com.sparsh.conferencedemo.models.Session;
import org.springframework.data.jpa.repository.JpaRepository;
public interface SessionRepository extends JpaRepository<Session, Long> {
}

Looks like you have run into the same issue that I have following Dan Bunker's spring boot Pluralsight course?
Looks like the course is a little out of date now and the latest version of spring boot doesn't appear to work with the project setup. Specifically I think it's a problem with how we have defined the JpaRespositories such that they cannot be auto wired.
Obviously if we are both following a beginners course it's a little tricky to establish the root cause.
I downgraded my project to 2.1.9.RELEASE in pom.xml:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.9.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
And it worked! Good luck.

I am trying to fetch data from database in my spring boot application. I am using hibernate libraries. Below is my entity class:

Here's the class with the method that fetches the data:

}
criteria.setFirstResult(startOffset);
criteria.setMaxResults(maxRows);
criteria.addOrder(Order.desc("id"));
criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
System.out.println("criteria: "+ criteria.toString());
discounts = criteria.list();
System.out.println("returned list from db:"+discounts);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
session.close();
}
return discounts;
}
I try to access the database exactly on the line:
discounts = criteria.list();
which is in the method find(GmCirculars obj, boolean activeOnly, int startOffset, int maxRows)
When I run my code, I am getting the following errors.

try to check if the table "MU_GM_CIRCULARS" exists in the database (probably yes) and whether you have access to it (probably not).
Connect the database using the credentials your code is using. Try the following
select * from dba_tables where table_name = 'MU_GM_CIRCULARS';
If there are any records, it means table exists in the system.
Next try this
select * from all_tables where table_name = 'MU_GM_CIRCULARS';
This will show if user has access to the table. If the table appears to be in the result, then check the "owner" column and try to reach the table using the following format
select * from owner.table_name
Hope this will help

It is a configuration issue of the database. I was adding a config.xml file, which is NOT needed in Spring Boot. Rather, I added these values to my application.properties file, and then everything worked fine.
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:#xxxxxxxxxxx
spring.datasource.username=xxxxx
spring.datasource.password=xxxxx

Unable to parse xml using XStreamMarshaller with spring batch + spring boot

I am trying to parse xml to java objects in spring batch and spring boot using XStreamMarshaller. everything was working fine and i was able to parse the file and get the required java objects but as soon as i introduced taskexecutor multithreading to improve my performance it starts to give me error which i'm unable to fix. I searched for the issue but didn't find any appropriate cause or response. Please help me to fix the issue or redirect me to some appropriate link which may solve my problem.
Thanks in advance...

As mentioned in its Javadoc, StaxEventItemReader is not thread safe. So using it in a multi-threaded step is not correct.
You need to wrap it in a SynchronizedItemStreamReader. In your case, it would be something like:
#StepScope
#Bean(name="xmlReader")
public SynchronizedItemStreamReader<StudentDTO> reader()
{
StaxEventItemReader<StudentDTO> xmlFileReader = new StaxEventItemReader<>();
xmlFileReader.setResource(new ClassPathResource("students.xml"));
xmlFileReader.setFragmentRootElementName("student");
Map<String, Class<?>> aliases = new HashMap<>();
aliases.put("student", StudentDTO.class);
XStreamMarshaller xStreamMarshaller = new XStreamMarshaller();
xStreamMarshaller.setAliases(aliases);
xmlFileReader.setUnmarshaller(xStreamMarshaller);
SynchronizedItemStreamReader< StudentDTO> synchronizedItemStreamReader = new SynchronizedItemStreamReader<>();
synchronizedItemStreamReader.setDelegate(xmlFileReader);
return synchronizedItemStreamReader;
}

Field itemRepository in HomePageController required a bean of type ItemRepository that could not be found

I'm new to spring boot and have been trying to make simple REST web application.
I followed steps as shown in different guides but i still get the same problem when i try to run application.
This is the output i see everytime i try to run code

}

Change spring-data-jpa to spring-boot-starter-data-jpa and remove hibernate dependency. It comes with starter.
In main class use #SpringBootApplication.

Not Sure if you are implementing ItemRepository interface anywhere. Please implement it and remove the #Repository from below code and place it to your implemented class.
#Repository
public interface ItemRepository extends CrudRepository<Item, Long>{
}
And Please change CrudRepository<Item, Long> to CrudRepository<Item, int>
Hope it will fix the issue.
