我无法从derby包导入JDBC客户端驱动程序 [英] I can't import the JDBC Client Driver from the derby package

问题描述

我有一个在Netbeans中运行的Java Derby数据库，我正在尝试使用JDBC驱动程序连接到它.但是，我不能专门从org.apache.derby包导入JDBC驱动程序.

I have a Java Derby database running in Netbeans and I'm trying to connect to it using the JDBC driver. However, I cannot import the JDBC driver specifically from the org.apache.derby package.

我所做的:

• 我的pom.xml文件包含以下Maven存储库

• My pom.xml file contains the following Maven repo's

<!-- https://mvnrepository.com/artifact/org.apache.derby/derby -->
<dependency>
    <groupId>org.apache.derby</groupId>
    <artifactId>derby</artifactId>
    <version>10.15.1.3</version>
    <type>jar</type>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.derby/derbyclient -->
<dependency>
    <groupId>org.apache.derby</groupId>
    <artifactId>derbyclient</artifactId>
    <version>10.15.1.3</version>
</dependency>
<dependency>
    <groupId>org.apache.derby</groupId>
    <artifactId>derbynet</artifactId>
    <version>10.15.1.3</version>
</dependency>

• Derby db属性表示数据库正在使用驱动程序您可以在此处看到

  当尝试导入JDBC驱动程序时，它似乎是derby导入列表中唯一缺少的内容

  When trying to import the JDBC driver, it is seemingly the only thing missing from the derby import list shown in this screenshot

  我还下载了derby.jar文件，并将其直接复制到C:\ Program Files \ Java \ jdk8-221 \ bin

  I have also downloaded the derby.jar file and copied it directly into C:\Program Files\Java\jdk8-221\bin

  我真的不明白为什么缺少JDBC驱动程序.

  I really can't understand why the JDBC driver specifically is missing.

  推荐答案

  我看到您正在使用10.15版.在此发行版中，Derby发行版在jar文件中的排列方式已更改，这可能会影响您.

  I see that you are using release 10.15. In this release, the arrangement of the Derby distribution into jar files has changed, and this is probably affecting you.

  请非常仔细地阅读 10.15发行说明，特别是请仔细查看"DERBY-6945的注意事项"部分，以获取有关如何更改类路径以访问Derby JDBC驱动程序类的详细信息.

  Please read the 10.15 Release Notes very carefully, and in particular please carefully look at the section "Note for DERBY-6945" for the details of how you have to change your classpath to access the Derby JDBC driver classes.

  可能您要做的就是包含 derbyshared.jar .但是请阅读全文.

  Probably, all you have to do is to include derbyshared.jar. But please read the entire thing.
