我有两个数据库在mysql服务器名为 Database1 & Database2 . Database1 有一张table Database1.dummy_table 带主键 Database1.dummy_table.id 作为整数和 Database2 有一张table Database2.dummy_table 带主键 Database2.dummy_table.id 作为biginteger。
我的spring配置文件如下：；

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context" default-lazy-init="true"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">

    <context:annotation-config/>

    <bean id="entityManagerFactoryBean" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="persistenceUnitName" value="default"/>
        <property name="packagesToScan" value="com.springapp.mvc.entity" />
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
        </property>
        <property name="jpaProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">validate</prop>
                <prop key="hibernate.dialect">com.springapp.dialect.Mysql5CustomDialect</prop>
            </props>
        </property>
    </bean>

    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.cj.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/Database1" />
        <property name="username" value="root" />
        <property name="password" value="" />
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactoryBean" />
    </bean>

    <bean id="persistenceExceptionTranslationPostProcessor" class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />
</beans>

在我的实体类id是整数，因为我正在连接 Database1 但是在服务器启动期间（tomcat7.0.91），我遇到了以下异常：；

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactoryBean' defined in ServletContext resource [/WEB-INF/config/repository-context.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Wrong column type in Database2.dummy_table for column ID.

如果我改变 Database2.dummy_table.id 整型或删除架构 Database2 应用程序运行良好。服务器如何验证的表 Database2 ? 我正在使用 Spring 4.3.10.RELEASE , Hibernate 4.3.7.Final & 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;
    }
}

将实体更改为：

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

必须使用正确的架构或目录对实体进行注解：
尝试使用默认目录调整您的配置：

<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，您应该定义并使用只能访问database1的mysql用户，而不是使用 root . 这样，hibernate将不会“看到”database2，因此不会尝试将database2.u表Map到实体。
