【问题描述】：

我正在尝试使用 Hibernate 和 SQL Server 2008。我在本地 Maven 存储库中安装了 sqljdbc4。它给了我一个错误，我无法继续前进。

我不确定我的本地存储库应该是什么样子（新手），但是 mvn 命令给出了错误：

当您尝试在本地 repo 中安装 sqljdbc4 时出现此错误？
你能提供你的 pom.xml 显示 sqljdbc4 依赖
com.microsoft.sqlserversqljdbc44.0

标签： java sql-server eclipse hibernate maven

【解决方案1】：

你试过这样的安装命令吗？

mvn install:install-file -Dfile=sqljdbc4.jar -Dpackaging=jar -DgroupId=com.microsoft.sqlserver -DartifactId=sqljdbc4 -Dversion=4.0

命令的典型 maven 输出

Maven 依赖应该是这样的：

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

将 sqljdbc4 安装到本地 maven 存储库的另一种替代方法是从本地文件系统引用它，但存在限制 - 路径是相对于特定 maven 模块的。在其中一个项目中，我将 sqljdbc 放在与 maven 模块目录处于同一级别的references 目录中，并添加如下：

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>4.0</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/../references/sqljdbc4.jar</systemPath>
</dependency>

【讨论】：

嗨@Viktor，我一直在尝试。我不确定问题出在哪里。 mvn 命令尝试下载，然后显示上面的错误。
刚刚尝试了我在 Windows 环境中的 Maven 3.2.3 上建议的命令。我编辑了我的答案并添加了 Maven 生成的输出。我不知道为什么它不适合你，可能是不同的版本或拼写错误的命令。

【解决方案2】：

我不久前找到了答案，但只是认为在这里发布它是公平的。

<property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:jtds:sqlserver://server/db</property>
    <property name="hibernate.connection.username">here</property>
    <property name="hibernate.connection.password">here</property>
    <property name="hibernate.connection.pool_size">100</property>
    <property name="show_sql">false</property>
    <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
