我在名为Database1和Database2的mysql服务器中有2个数据库。

Database1有一个表Database1.dummy_table，表的主键为Database1.dummy_table.id为整数 并且Database2的表Database2.dummy_table的主键Database2.dummy_table.id为biginteger。

我的spring配置文件如下； 

<?xml version="1.0" encoding="UTF-8"?>

在我与Database1连接时，我的实体类ID为Integer，但是在服务器启动期间（tomcat 7.0.91）我收到以下异常；

如果我将Database2.dummy_table.id更改为整数或删除模式Database2，应用程序将正常运行。服务器如何验证Database2的表？我正在使用Spring 4.3.10.RELEASE，Hibernate 4.3.7.Final和Mysql 8.0.12。

Database1表脚本：

CREATE TABLE `dummy_table` (
    `ID` INT NOT NULL AUTO_INCREMENT,
    `MeterNo` VARCHAR(45) NOT NULL,
    `Status` INT NOT NULL,
PRIMARY KEY (`ID`));

Database2表脚本：

CREATE TABLE `dummy_table` (
    `ID` BIGINT NOT NULL AUTO_INCREMENT,
    `MeterNo` VARCHAR(45) NOT NULL,
    `Status` INT NOT NULL,
PRIMARY KEY (`ID`));

我的应用程序中的实体

@Entity
@Table(name = "dummy_table")
public class DummyTable implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "ID")
    private Integer id;

    @Column(name = "MeterNo")
    private String meterNo;

    @Column(name = "Status")
    private Integer status;

    public Integer getId() {
        return id;
    }

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

    public String getMeterNo() {
        return meterNo;
    }

    public void setMeterNo(String meterNo) {
        this.meterNo = meterNo;
    }

    public Integer getStatus() {
        return status;
    }

    public void setStatus(Integer status) {
        this.status = status;
    }
}

必须使用正确的架构或目录对实体进行注释：

尝试使用 default_catalog 调整您的配置：

    <property name="jpaProperties">
        <props>
            <prop key="hibernate.hbm2ddl.auto">validate</prop>
            <prop key="hibernate.dialect">com.springapp.dialect.Mysql5CustomDialect</prop>
            <prop key="hibernate.default_catalog">Database1</prop>
        </props>
    </property>

或者，您应该定义并使用 mysql用户，该用户仅只能访问Database1 ，而不是使用root。这样，Hibernate将不会“看到” Database2，因此将不会尝试将Database2.dummy_table映射到该实体。

将您的实体更改为：

@Entity
@Table(catalog = "Database1", name = "dummy_table")
public class DummyTable implements Serializable {
