使用名稱'entityManagerFactory'spring-mvc創建bean的錯誤，數據

再次:)。在我的項目中，我問過很多問題。現在我幾乎完成它。還有，有一個問題。這是使用名稱'entityManagerFactory'spring-mvc創建bean的錯誤，數據

我覺得這是我的becouse實體類的數據庫中有其他名稱，則表，但林不知道。也是我從實體類的子級（這是可能的）據我所知SessionFactory不能創建..但爲什麼不？）連接數據庫是成功的。我測試過了。

這裏是我的實體類：

@Entity 
@Table(name = "users") 
public class UserEntity { 

@Id 
@GeneratedValue(strategy = GenerationType.AUTO) 
private Long id; 

@Column(name = "username") 
protected String username; 

@Column(name = "password") 
protected String password; 

@Transient 
private String confirmPassword; 

@ManyToMany 
@JoinTable(name = "user_roles", joinColumns = @JoinColumn(name = "user_id"), 
     inverseJoinColumns = @JoinColumn(name = "role_id")) 
private Set<Role> roles; 

public Long getId() { 
    return id; 
} 

public void setId(Long id) { 
    this.id = id; 
} 

public String getUsername() { 
    return username; 
} 

public void setUsername(String username) { 
    this.username = username; 
} 

public String getPassword() { 
    return password; 
} 

public void setPassword(String password) { 
    this.password = password; 
} 

public String getConfirmPassword() { 
    return confirmPassword; 
} 

public void setConfirmPassword(String confirmPassword) { 
    this.confirmPassword = confirmPassword; 
} 

public Set<Role> getRoles() { 
    return roles; 
} 

public void setRoles(Set<Role> roles) { 
    this.roles = roles; 
}

}

@Entity 
@Table(name = "roles") 
public class RoleEntity{ 

@Id 
@GeneratedValue(strategy = GenerationType.AUTO) 
private Long id; 

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

@ManyToMany(mappedBy = "roles") 
private Set<User> users; 

public RoleEntity() { 
} 

public Long getId() { 
    return id; 
} 

public void setId(Long id) { 
    this.id = id; 
} 

public String getName() { 
    return name; 
} 

public void setName(String name) { 
    this.name = name; 
} 

public Set<User> getUsers() { 
    return users; 
} 

public void setUsers(Set<User> users) { 
    this.users = users; 
} 

@Override 
public String toString() { 
    return "Role{" + 
      "id=" + id + 
      ", name='" + name + '\'' + 
      ", users=" + users + 
      '}'; 
}

}

子類：

public class User extends UserEntity implements Comparable { 

private boolean isOnline; 
private String sex; 
private int age; 
private String comment; 
private String email; 
private String friendsLogins; 
private Session session; 

public User(String login, String password) { 
    this.sex = null; 
    this.comment = null; 
    this.email = null; 
    this.friendsLogins = ""; 

} 

public User(User user) { 
    this.sex = user.getSex(); 
    this.comment = user.getComment(); 
    this.email = user.getComment(); 
    this.friendsLogins = ""; 

} 

public User(String login, String password, boolean isOnline, String sex, int age, String comment, String email) { 
    this.sex = sex; 
    this.age = age; 
    this.comment = comment; 
    this.email = email; 
    this.friendsLogins = ""; 
} 

public Session getSession() { 
    return session; 
} 

public void setSession(Session session) { 
    this.session = session; 
} 


public boolean isOnline() { 
    return isOnline; 
} 

public void setOnline(boolean online) { 
    isOnline = online; 
} 

public String getSex() { 
    return sex; 
} 

public void setSex(String sex) { 
    this.sex = sex; 
} 

public int getAge() { 
    return age; 
} 

public void setAge(int age) { 
    this.age = age; 
} 

public String getComment() { 
    return comment; 
} 

public void setComment(String comment) { 
    this.comment = comment; 
} 

public String getEmail() { 
    return email; 
} 

public void setEmail(String email) { 
    this.email = email; 
} 

public String getFriendsLogins() { 
    return friendsLogins; 
} 

public void setFriendsLogins(String friendsLogins) { 
    this.friendsLogins = friendsLogins; 
} 

public boolean equals(Object obj) { 
    User user = (User) obj; 
    if (user.getPassword().equals(this.password) && user.getUsername().equals(this.username)) { 
     return true; 
    } else { 
     return false; 
    } 
} 


@Override 
public int compareTo(Object o) { 
    User user = (User) o; 
    if (user.getPassword().equals(this.password) && user.getUsername().equals(this.username)) { 
     return 0; 
    } else if (user.getAge() > this.getAge()) { 
     return -1; 
    } else { 
     return 1; 
    } 
}

}

和XML文件：

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 
    <property name="driverClassName" value="${jdbc.driverClassName}"/> 
    <property name="url" value="${jdbc.url}"/> 
    <property name="username" value="${jdbc.username}"/> 
    <property name="password" value="${jdbc.password}"/> 
</bean> 

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="dataSource" ref="dataSource"/> 
    <property name="packagesToScan" value="com.chat.my.model"/> 
    <property name="jpaVendorAdapter"> 
     <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/> 
    </property> 
    <property name="jpaProperties"> 
     <props> 
      <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop> 
      <prop key="hibernate.show_sql">true</prop> 
     </props> 
    </property> 
</bean> 

<bean id="transactionManager" 
     class="org.springframework.orm.jpa.JpaTransactionManager"> 
    <property name="entityManagerFactory" ref="entityManagerFactory"/> 
</bean> 

<tx:annotation-driven/> 
<jpa:repositories base-package="com.chat.my.dao"/>

所以，我不能明白爲什麼。在我添加一些類之前，我沒有像上面那樣的問題。請幫忙解決）

笑話一種脂肪酶:)

德國去超市由寶馬和梅賽德斯出國; 法國法國人去雷諾超市，標緻出國; 俄羅斯人乘無軌電車去超市，然後乘坦克出國。

可以粘貼完整的堆棧跟蹤嗎？ –

我認爲會更好，如果給Git .. https://github.com/lars1son/MyChat1.3 –

但要找到確切的根源，我們需要看到異常stacktrace –

在您的UserEntity課程中，您正在映射Role。但是在你發佈的代碼中，你有一個名爲RoleEntity的類，是你實際試圖映射的類嗎？

@ManyToMany 
@JoinTable(name = "user_roles", joinColumns = @JoinColumn(name = "user_id"), 
     inverseJoinColumns = @JoinColumn(name = "role_id")) 
private Set<Role> roles;

應該是這個嗎？

private Set<RoleEntity> roles;

看起來像是真的，所以，在有用性中，anototation也必須改變..！？ –

我認爲在'RoleEntity.java'中，你也需要改變'private Set users;'to'private Set users;'但我不完全確定你的項目是如何映射的。 –
