通过持久性连接到mssql而不复制DLL

标签: java sql-server maven jpa persistence.xml

我在java中使用persistence.xml建立了与mssql的连接。为此,我必须将sqljdbc_auth.dll复制到system32,因为我想使用Windows身份验证才能连接。有没有办法在不复制dll文件的情况下实现相同的结果?删除dll会导致此警告并阻止执行:

Failed to load the sqljdbc_auth.dll cause : no sqljdbc_auth in java.library.path

这是我的坚持:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="migration">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>migration.xcs.model.Kennzahl</class>
    <properties>
        <property name="javax.persistence.jdbc.driver"
            value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
        <property name="hibernate.dialect"  value="org.hibernate.dialect.SQLServerDialect" />
        <property name="javax.persistence.jdbc.url"
            value="jdbc:sqlserver://localhost:1433;databaseName=kendb;integratedSecurity=true;" />
        <property name="hibernate.archive.autodetection" value="class" />

    </properties>
</persistence-unit>

这些是我的pom依赖:

您尚未添加sqljdbc_auth.dll所在的路径 找出DLL所在的系统,并将其添加到classpath

或者在你的Eclipse中,你可以Run Configuration这样:

 -Djava.library.path=C:\path of the dll\
