Spring 컨트롤러가 연결을 처리 할 때 :
@RequestMapping(value = "/user", method = RequestMethod.GET)
public @ResponseBody User getUser(@RequestParam(value="id", required=true) int id) {
User user = null;
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring-config.xml");
UserService userService = (UserService) context.getBean("userService");
user = userService.getUser(id);
context.close();
return user;
}
userService에서 getUser를 수행합니다.
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
@Component
public class UserService {
private UserDAO userDao;
public UserDAO getUserDao() {
return userDao;
}
@Autowired
public void setUserDao(UserDAO userDao) {
this.userDao = userDao;
}
public void addUser(User user) {
getUserDao().insert(user);
}
public User getUser(int id) {
return getUserDao().load(id);
}
public List<User> fetchAllPersons() {
return getUserDao().selectAll();
}
}
엔티티를 찾기 위해 userDao를 사용하는 :
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
@Repository("userDao")
@Transactional(propagation = Propagation.REQUIRED)
public class UserDAO {
private static final String SELECT_QUERY = "select u from users";
@Qualifier(value = "entityManagerFactory")
private EntityManager entityManager;
public EntityManager getEntityManager() {
return entityManager;
}
public void setEntityManager(EntityManager entityManager) {
this.entityManager = entityManager;
}
public void insert(User user) {
entityManager.persist(user);
}
public User load(int id) {
return entityManager.find(User.class, id);
}
public List<User> selectAll() {
Query query = entityManager.createQuery(SELECT_QUERY);
@SuppressWarnings("unchecked")
List<User> users = (List<User>) query.getResultList();
return users;
}
}
나는 / src / main / resources에 다음과 같은 spring-config.xml을 가지고있다.
<?xml version="1.0" encoding="UTF-8"?>

이 오류를 해결하려면 무엇을해야합니까?
솔직히, 이것이 해결 될 때, 아마도 JndiException을 얻을 것입니다. 그 원인이 무엇일까요?
해결법
-
==============================
1.나는 hibernate-entitymanager의 버전을 hibernate-core와 같도록 덮어 썼다. 결정된.

2.당신이 pom.xml에서 hibernate-core와 hibernate-entitymanager를 사용하고 있다면, 그들은 같은 버전이어야합니다. 나는 이것을 시도하고 해결했다.
당신이 pom.xml에서 hibernate-core와 hibernate-entitymanager를 사용하고 있다면, 그들은 같은 버전이어야합니다. 나는 이것을 시도하고 해결했다.

==============================
3.2 가지 이유가있을 수 있습니다.
2 가지 이유가있을 수 있습니다.
1 : JNDIException을 포함하는 적절한 하이버 네이트 라이브러리가 클래스 패스 내에 없다.
2 : 중복 된 hibernate.jars간에 버전 충돌이 있습니다. 이것은 이미 동일한 라이브러리를 제공하지만 버전이 다른 JEEContainer (서버) 내에 애플리케이션을 배치하려고 할 때 발생할 수 있습니다.
JNDIException 클래스를 해결할 수있을 때 오류 메시지에서 주요 문제가 분명해진다.

==============================
4.먼저 ClassNotFoundException을 해결하려고합니다. 오류 메시지는 무엇이 잘못되었는지 더 잘 이해할 수 있어야합니다.
먼저 ClassNotFoundException을 해결하려고합니다. 오류 메시지는 무엇이 잘못되었는지 더 잘 이해할 수 있어야합니다.
그렇게하기 위해서 당신의 hibernate-core lib와 hibernate-entitymanager lib의 버전 번호를 확인하십시오. 또한 최대 절전 모드 버전이 jboss 동면 버전과 충돌하지 않는지 확인하십시오.
