Hibernate和Maven：无法从资源解析映射文档

Question

当我尝试用Maven编译时，我得到了这个错误：

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：

user.java

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;
}

Answer 1

你有

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

但是hibernate抱怨找不到com/baskeitor/models/user.hbm.xml。这个值显然是由hibernate任意设置的，所以必须在某个地方设置它。尝试和搜索周围使用任何工具，你喜欢搜索通过文件。

另外，hibernate-mapping元素的package属性也有问题，它在hbm文件中设置为com.project.models，但实际的包是main.java.com.project.models。
