java - 将 Hibernate xml 配置文件从 hypersql 转换为 mssql

Question

我的应用程序在内存数据库中的 hypersql 上工作正常，但是，当我尝试迁移到 MSSQL 时，应用程序抛出异常。

我在POM文件中添加了mssql的依赖项:

<dependency>
        <groupId>com.microsoft.sqlserver</groupId>
        <artifactId>mssql-jdbc</artifactId>
        <version>6.4.0.jre8</version>
        <scope>test</scope>
    </dependency>

hibernate xml 文件中的 mssql 的以下无效代码:

 <hibernate-configuration>
    <session-factory>
        <property name="hibernate.archive.autodetection">class,hbm</property>
        <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
        <property name="hibernate.connection.username">ABCD</property>
        <property name="hibernate.connection.password">0000</property>
        <property name="hibernate.connection.url">jdbc:sqlserver://localhost:1433;databasename=c1;</property>
        <property name="hibernate.hbm2ddl.auto">create</property>
    </session-factory>
</hibernate-configuration>

hibernate xml 文件中的 hypersql 的以下工作代码:

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.archive.autodetection">class,hbm</property>
        <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
        <property name="hibernate.connection.username">sa</property>
        <property name="hibernate.connection.password"></property>
        <property name="hibernate.connection.url">jdbc:hsqldb:mem:howtodoinjava</property>
        <property name="hibernate.hbm2ddl.auto">create</property>

        <property name="hibernate.c3p0.min_size">5</property>
        <property name="hibernate.c3p0.max_size">20</property>
        <property name="hibernate.c3p0.acquire_increment">2</property>
        <property name="hibernate.c3p0.acquire_increment">1800</property>
        <property name="hibernate.c3p0.max_statements">150</property>
    </session-factory>
</hibernate-configuration>

应用程序抛出异常，例如:

Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

原因:

java.lang.ClassNotFoundException: Could not load requested class : com.microsoft.sqlserver.jdbc.SQLServerDriver

 org.hibernate.boot.registry.classloading.spi.ClassLoadingException: Unable to load class [com.microsoft.sqlserver.jdbc.SQLServerDriver]

  org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'getSessionFactory'

Answer 1

您的连接设置链接到了错误的驱动程序。

<property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>

将其指向您在 pom.xml 中导入的同一个 ( <groupId>com.microsoft.sqlserver</groupId> )

com.microsoft.sqlserver.jdbc.SQLServerDriver
