java - Postgres 中的 Bad Integer 2147483649(其 BIGINT 值)错误

Question

我正在使用带 hilo key 生成器和 Postgres 9.3 的 hibernate 3。表列是 BIGINT，模型类变量是 long(java)。

从后端没有问题，但是当我尝试从前端控制台保存时显示 Bad Integer '2147483649' 错误。 表架构是:

CREATE TABLE user_log
(
  id bigint NOT NULL,
  appuser_id bigint,
  user_role_id bigint,
  login_time timestamp without time zone,
  logout_time timestamp without time zone,
  logged_in_ip character varying(32),
  CONSTRAINT user_log_pkey PRIMARY KEY (id),
  CONSTRAINT fk_app_user FOREIGN KEY (appuser_id)
      REFERENCES app_user (id) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION,
  CONSTRAINT fk_user_role FOREIGN KEY (user_role_id)
      REFERENCES user_role (id) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION
)

模型类:

public class UserLog extends ModelBase {

/** identifier field */
private Long id;

/** persistent field */
private AppUser user;

/** nullable persistent field */
private Date loginTime;

/** nullable persistent field */
private Date logoutTime;

/** nullable persistent field */
private UserRole loggedInRole;

/** nullable persistent field */
private String loggedInIP;

/**
 * @hibernate.id generator-class="hilo"  column="id"
 * 
 */
public Long getId() {
    return this.id;
}

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

/**
 * @hibernate.many-to-one
 * @hibernate.column name="user_role_id"
 * 
 */
public UserRole getLoggedInRole() {
    return loggedInRole;
}

public void setLoggedInRole(UserRole loggedInRole) {
    this.loggedInRole = loggedInRole;
}

/**
 * @hibernate.property column="login_time" type="java.util.Date"
 * 
 */
public Date getLoginTime() {
    return loginTime;
}

public void setLoginTime(Date loginTime) {
    this.loginTime = loginTime;
}

/**
 * @hibernate.property column="logout_time" type="java.util.Date"
 * 
 */
public Date getLogoutTime() {
    return logoutTime;
}

public void setLogoutTime(Date logoutTime) {
    this.logoutTime = logoutTime;
}

/**
 * @hibernate.many-to-one
 * @hibernate.column name="appuser_id"
 * 
 */
public AppUser getUser() {
    return user;
}

public void setUser(AppUser user) {
    this.user = user;
}

/**
 * @hibernate.property column="logged_in_IP" length="32"
 * 
 */
public String getLoggedInIP() {
    return loggedInIP;
}

public void setLoggedInIP(String loggedInIP) {
    this.loggedInIP = loggedInIP;
}

Answer 1

当 Hibernate 试图为 user_log 表创建一个新的 id 时，就会发生错误。

在您的应用程序中，Hibernate 使用 org.hibernate.id.TableGenerator 生成 ID，而 ID 又希望返回一个整数。这会导致异常，因为下一个可用 ID 大于 Integer.MAX_VALUE。

自 Javadoc 以来，您似乎正在使用 < 3.5 的 Hibernate 版本说:

Again, the return types supported here are any of the ones supported by IntegralDataTypeHolder. This is new as of 3.5. Prior to that this generator only returned Integer values.

因此，即使您在表和 POJO 中使用了正确的数据类型，TableGenerator 也只能返回整数，除非您更新到更新的 Hibernate 版本。
