hibernate 实现用户角色对应关系的问题

Question

[size=small][color=olive]简单的权限管理表设计
不知道这样的表间对应关系是否正确，包含用户，角色
以及中间表 ，还请指教。[/color][/size]
PubUser（用户表）
简化代码
[code="java"]
{
private Integer userId;
private Set pubUsersRoleses = new HashSet(0);

@Id
@GeneratedValue
@Column(name = "user_id", unique = true, nullable = false)
public Integer getUserId() {
    return this.userId;
}

public void setUserId(Integer userId) {
    this.userId = userId;
}

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "pubUsers")
public Set<PubUsersRoles> getPubUsersRoleses() {
    return this.pubUsersRoleses;
}

public void setPubUsersRoleses(Set<PubUsersRoles> pubUsersRoleses) {
    this.pubUsersRoleses = pubUsersRoleses;
}

}
[/code]
pubRoles（角色表）
[code="java"]

@Entity
public class PubRoles implements java.io.Serializable {

private Integer roleId;

private Set<PubUsersRoles> pubUsersRoleses = new HashSet<PubUsersRoles>(0);


@Id
@GeneratedValue
@Column(name = "role_id", unique = true, nullable = false)
public Integer getRoleId() {
    return this.roleId;
}

public void setRoleId(Integer roleId) {
    this.roleId = roleId;
}



@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "pubRoles")
public Set<PubUsersRoles> getPubUsersRoleses() {
    return this.pubUsersRoleses;
}

public void setPubUsersRoleses(Set<PubUsersRoles> pubUsersRoleses) {
    this.pubUsersRoleses = pubUsersRoleses;
}

}
[/code]
pubUsersRoles (用户角色中间表)
[code="java"]

public class PubUsersRoles implements java.io.Serializable {

private Long id;
private PubUsers pubUsers;
private PubRoles pubRoles;


@Id
@GeneratedValue
@Column(name = "id", unique = true, nullable = false, precision = 12, scale = 0)
public Long getId() {
    return this.id;
}

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

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "user_id")
public PubUsers getPubUsers() {
    return this.pubUsers;
}

public void setPubUsers(PubUsers pubUsers) {
    this.pubUsers = pubUsers;
}

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "role_id")
public PubRoles getPubRoles() {
    return this.pubRoles;
}

public void setPubRoles(PubRoles pubRoles) {
    this.pubRoles = pubRoles;
}

}
[/code]

正确。角色和权限再对应关系就好了。
