Question

我有一个名为＆＃34; User＆＃34;的实体。由于Oracle无法创建具有该名称的表，因此我给它@Entity（name =）和@Table（name =）属性以确保它可以创建。但是，由于某些原因，表格还没有创建。为了使事情变得更奇怪，所有定义的@JoinTable都是正确创建的，具有相应的名称。任何人都知道可能导致这种情况的原因吗？

我的课程：

@Entity(name="USERTABLE")
@Table(name="USERTABLE")
public class User implements Serializable {
private static final long serialVersionUID = -3895959057511877608L;

private Integer id;
private String name;
private String userName;
private Domain domain;
private String password;
private Boolean mustChangePassword;
private String email;
// 19/07/2012 RP [WEAVER-83]
private Date lastLogin;
private List<Profile> profiles = new ArrayList<Profile>();
private List<Role> roles = new ArrayList<Role>();

@Id
@GeneratedValue(generator="user_seq")
@SequenceGenerator(name="user_seq",sequenceName="User_Sequence",allocationSize=1)
public Integer getId() {
    return id;
}

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

public String getName() {
    return name;
}

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

@Column(unique = true)
public String getUserName() {
    return userName;
}

public void setUserName(String userName) {
    this.userName = userName;
}

@ManyToOne
public Domain getDomain() {
    return domain;
}

public void setDomain(Domain domain) {
    this.domain = domain;
}

public String getPassword() {
    return password;
}

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

@Column(columnDefinition = "tinyint")
public Boolean getMustChangePassword() {
    return mustChangePassword;
}

public void setMustChangePassword(Boolean mustChangePassword) {
    this.mustChangePassword = mustChangePassword;
}

public String getEmail() {
    return email;
}

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

public Date getLastLogin() {
    return lastLogin;
}

public void setLastLogin(Date lastLogin) {
    this.lastLogin = lastLogin;
}

@ManyToMany
@JoinTable(joinColumns = { @JoinColumn(name = "user_id") }, inverseJoinColumns = { @JoinColumn(name = "profile_id") })
@IndexColumn(name = "listOrder")
public List<Profile> getProfiles() {
    return profiles;
}

public void setProfiles(List<Profile> profiles) {
    this.profiles = profiles;
}

@ManyToMany
@JoinTable(joinColumns = { @JoinColumn(name = "user_id") }, inverseJoinColumns = { @JoinColumn(name = "role_id") })
@IndexColumn(name = "listOrder")
public List<Role> getRoles() {
    return roles;
}

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

我的persistence.xml：

    <?xml version="1.0" encoding="UTF-8"?>
<persistence
    xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
      <!-- <property name="hibernate.hbm2ddl.auto" value="update"/> -->

    </properties>
  </persistence-unit>  
</persistence>

更新：我尝试创建一个命名策略，在每个表的开头添加一个前缀，但该表仍然是未创建的

Answer 1

好的，我发现了问题。我没有注意到布尔被设置为'tinyint'（在OracleSQL中是不存在的）并且Date不能在OracleSQL中正常保存（你需要为它分配一个@ Temporal = TemporalType.TIMESTAMP来执行它）。删除'tinyint'部分并添加anotation解决了它。故事的道德：总是检查数据类型。

Hibernate没有在DB中创建一个命名表
