当我尝试使用 Maven 编译时，出现此错误：

INFO: HHH000041: Configured SessionFactory: null
Error creating Session: org.hibernate.InvalidMappingException: Could not parse mapping document from resource com/baskeitor/models/User.hbm.xml

但我看不出错误在哪里：

用户.java

包 main.java.com.project.models；

公共类用户实现 java.io.Serializable {

private static final long serialVersionUID = 1L;

private Long id;

private String firstName;
private String secondName;
private String email;
private String password;
private Set<Artifact> artifact = new HashSet<Artifact>();

public User(){}

public User(String firstName, String secondName, String email, String password){
    this.firstName = firstName;
    this.secondName = secondName;
    this.email = email;
    this.password = password;
}   

public Long getId() {
    return id;
}

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

public Set<Artifact> getArtifacts() {
    return teams;
}

public void setArtifacts(Set<Artifact> artifacts) {
    this.teams = team;
}

public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getSecondName() {
    return secondName;
}

public void setSecondName(String secondName) {
    this.secondName = secondName;
}

public String getEmail() {
    return email;
}

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

public String getPassword() {
    return password;
}

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

}

用户.hbm.xml

    </session-factory>

当 maven 运行测试时我收到此错误，我尝试获取 HibernateUtil.getSessionFactory();

这里似乎有几个问题，首先，找不到休眠映射文件。奇怪的是，您在 Maven 输出中给出的位置与您在休眠配置中指定的位置不匹配。

你有

<mapping resource="com/project/models/User.hbm.xml"/>

但是hibernate抱怨找不到com/baskeitor/models/User.hbm.xml。这个值显然是hibernate随意编造的，所以一定要在某个地方设置。尝试使用您喜欢搜索文件的任何工具搜索它。

此外，您的 hibernate-mapping 元素的 package 属性存在问题，它com.project.models在您的 hbm 文件中设置，但实际包是main.java.com.project.models.

因此，由于您在 hibernate-mapping 元素中指定的包名在映射文档中的非限定类名前面加上前缀，因此类元素中的类名将是 com.project.models.User，这与实际类名。

（在一个侧面节点上，为什么不使用注释？他们觉得使用 imho 更自然）
