Hibernateアプリケーションを実行中に 'java.lang.IllegalArgumentException：Unknown entity'を取り除くには？

Question

私は休止状態に新しいですし、それを使用して小さなアプリケーションを作成しながら、私は、例外（エラーがEntityManagerのの存続に関連している）次しまっ：

java.lang.IllegalArgumentException: Unknown entity: com.nataniel.api.domain.User 
    at org.hibernate.ejb.AbstractEntityManagerImpl.persist(AbstractEntityManagerImpl.java:840) 
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) 
    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) 
    at java.lang.reflect.Method.invoke(Method.java:497) 
    at org.springframework.orm.jpa.SharedEntityManagerCreator$SharedEntityManagerInvocationHandler.invoke(SharedEntityManagerCreator.java:240) 
    at com.sun.proxy.$Proxy993.persist(Unknown Source) 
    at com.nataniel.api.services.UserService.createUser(UserService.java:29) 

誰も私を助けてくださいことはできますか？次のように

Entityクラスは次のとおりです。

エンティティユーザー：

package com.nataniel.api.domain; 
import org.hibernate.annotations.Entity; 
import javax.persistence.Column; 
import javax.persistence.GeneratedValue; 
import javax.persistence.Id; 
import javax.persistence.Table; 
@Entity 
@Table(name="USER") 
public class User { 
    @Id 
    @GeneratedValue(strategy=GenerationType.IDENTITY) 
    private Long id; 

    @Column(name = "LOGIN") 
    private String login; 

    @Column(name = "NAME") 
    private String name; 

    @Column(name = "EMAIL") 
    private String email; 

    @Column(name = "PASSWORD") 
    private String password; 

    @Column(name = "CITY") 
    private String city; 

    @Column(name = "REGION") 
    private String region; 

    @Column(name = "BIRTHDATE") 
    private String birthDate; 

    public User() { 
    } 

    public User(String login, String name, String email, String password, String city, String region, String birthDate) { 
     this.login = login; 
     this.name = name; 
     this.email = email; 
     this.password = password; 
     this.city = city; 
     this.region = region; 
     this.birthDate = birthDate; 
    } 

    // getters and setters 
} 

DAOファイル：

package com.nataniel.api.services; 
import org.apache.camel.Exchange; 
import org.json.JSONObject; 
import org.springframework.stereotype.Service; 
import com.nataniel.api.domain.User;

import javax.persistence.EntityManagerFactory; 
import javax.persistence.Persistence; 
import javax.persistence.PersistenceContext; 
@Service("userService") 
public class UserService { 

    @PersistenceContext 
    transient EntityManager entityManager; 

    @Transactional 
    public String createUser(Exchange exchange) { 
     JSONObject userAccountJSON = (JSONObject) exchange.getIn().getHeader("jsonRequest"); 

     User user = new User(); 
     user.setLogin(userAccountJSON.getString("login")); 
     user.setEmail(userAccountJSON.getString("email")); 
     user.setPassword(userAccountJSON.getString("password")); 
     user.setName(userAccountJSON.getString("name")); 
     user.setCity(userAccountJSON.getString("city")); 
     user.setRegion(userAccountJSON.getString("region")); 
     user.setBirthDate(userAccountJSON.getString("birthdate")); 
     entityManager.persist(user); 

     return userAccountJSON.toString(); 
    } 
}

エンティティUserでこれを追加してみてください。

@Entity 
@javax.persistence.Entity; // add this <-- 
@Table(name="USER") 

私はそれが休止状態API Entityではなく永続Entityに達するので、あなたのユーザエンティティが配置されていないと思います。
