休眠和SQL Server依賴

Question

我想使用Hibernate和SQL Server 2008.我遇到過安裝sqljdbc4到我的本地Maven倉庫。它給了我一個錯誤，我無法前進。

我不知道我的本地庫應該怎麼樣子（新手），但MVN指令給出錯誤：

Answer 1

我找到了答案而回，但只是認爲這是公平的張貼這裏。

<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> 

Answer 2

你有triend安裝命令這樣嗎？在命令

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

典型行家輸出

Maven的依賴關係應該是這樣的：

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

在安裝sqljdbc4到本地倉庫另一種選擇是從本地文件系統中引用它，但有一些限制 - path是相對於特定的maven模塊。在項目之一，我把sqljdbc在references目錄是在同一水平行家modules目錄，並添加它，如下所示：

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