Я создаю приложение Spring Boot для извлечения данных из базы данных Oracle и отображения их в виде строки. Вот мой pom.xml

Может кто-нибудь помочь с этим, пожалуйста? ServerConfig — это мой класс Entity, а мой контроллер просто вызывает метод getAllConfigurationData() и печатает возвращаемый список в виде строки.

package com.mygit.boot.dao.impl;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.mygit.boot.dao.IFetchDao;
import com.mygit.boot.entity.ServerConfig;

@Repository
@Transactional
public class FetchDaoImpl implements IFetchDao {

@PersistenceContext
private EntityManager entityManger;

@Override
public List getAllConfigurationData() {
try {
return entityManger.createQuery("select c from ServerConfig c", ServerConfig.class).getResultList();

} catch (Exception e) {
System.out.println("Exception while fetching server config !!!");
}
return null;
}
}


Вот моя ошибка:

java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.data.web.SpringDataWebAutoConfiguration.pageableCustomizer

Caused by: java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/ObjectMapper


Контроллер:

package com.mygit.boot.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.mygit.boot.entity.ServerConfig;

@RestController
public class TestController {

@Autowired
private IFetchDao fetchDao;

@RequestMapping("/test")
public String print() {

List l=fetchDao.getAllConfigurationData();
return l.toString();
}
}
