Question

我正在尝试通过spring和hibernate连接并使用MSSQL。我收到以下错误

使用的dialect是org.hibernate.dialect.SQLServer2012Dialect，用于连接的驱动程序是com.microsoft.sqlserver.jdbc.SQLServerDriver。我可能做错了什么？

我尝试设置属性validationQuery

<bean class="org.apache.commons.dbcp2.BasicDataSource">
 <property name="connectionProperties"
             value="password=123;user=111"></property>
             <property name="maxTotal"  
value="8" />
            <property name="driverClassName" 
value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
            <property name="url" 
value="url" />
            <property name="testOnBorrow" value="true"/>
            <property name="validationQuery" value="select 1" />
</bean>

驱动程序的Maven依赖项是

    <dependency>
        <groupId>com.microsoft.sqlserver</groupId>
        <artifactId>sqljdbc4</artifactId>
        <version>4.0</version>
    </dependency>

我了解到在初始化bean时由dbcp2建立连接是一个问题。所以我更新了sql驱动程序，它为我解决了问题。

<!-- https://mvnrepository.com/artifact/com.microsoft.sqlserver/mssql-jdbc -->
    <dependency>
        <groupId>com.microsoft.sqlserver</groupId>
        <artifactId>mssql-jdbc</artifactId>
        <version>6.1.0.jre8</version>
    </dependency>

为我的MSSQL配置加载Bean对象时发生AbstractMethodError
