Question

我（据我所知）正确地遵循xwiki.org上的所有说明，我也搜索了我的错误的答案，但遗憾的是我自己无法解决这些问题。

我已经以两种不同的格式下载了XWiki。第一个是.exe安装程序，第二个是建议的.xar程序包，两者都可以在Windows 8,64位计算机上使用。

第一个在“独立”模式下运行完美，但是一旦hibernate.cfg.xml文件更改为预设的MySQL设置（对我的数据库准确），我会收到很长的HTTP 500错误。（这是在我添加MySQL Connection Java文件，并根据xwiki.org上的说明创建了一个MySQL数据库之后）似乎主要问题是它无法找到com.mysql.jdbc.Driver以及我得到的事实页面上稍后出现错误，指出它无法创建数据库连接池。

与错误有关的代码是：

<!-- DBCP Connection Pooling configuration
-->
<property name="dbcp.defaultAutoCommit">false</property>
<property name="dbcp.maxActive">50</property>
<property name="dbcp.maxIdle">5</property>
<property name="dbcp.maxWait">30000</property>
<property name="dbcp.whenExhaustedAction">1</property>
<property name="dbcp.ps.whenExhaustedAction">1</property>
<property name="dbcp.ps.maxWait">120000</property>
<property name="dbcp.ps.maxIdle">20</property>
<property name="connection.provider_class">com.xpn.xwiki.store.DBCPConnectionProvider</property>

和这个

<!-- MySQL configuration.

-->
<property name="connection.url">jdbc:mysql://localhost/xwiki</property>
<property name="connection.username">xwiki</property>
<property name="connection.password">xwiki</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
<property name="dbcp.ps.maxActive">20</property>
<mapping resource="xwiki.hbm.xml"/>
<mapping resource="feeds.hbm.xml"/>
<mapping resource="activitystream.hbm.xml"/>
<mapping resource="instance.hbm.xml"/>

错误本身如下：

我是否必须使用.xar安装版本才能正确连接到数据库？我也尝试过这种方式，使用Xampp和Tomcat。 Tomcat安装正常，我可以通过localhost:(port)轻松访问它。但是，当我尝试访问我的xwiki时，我收到HTTP 404错误，指出无法找到引用，这很奇怪，因为它显示了Tomcat中包含的部署列表中的其他文件，以及Tomcat示例那里显示的文件（位于同一目录中）工作正常...

我有点担心，即使我能让XWiki通过Tomcat正常工作，我仍会得到我后来在尝试连接MySQL数据库时提到的第一个错误。

Side注意：我怀疑在XWiki中发现的那些与Tomcat中的那些之间可能存在Java文件冲突，这些错误是我在玩游戏时尝试使用的其他错误...但我可以是错的，因为我目前对Java知之甚少。我已经看到了几个servlet错误，并且根据我发现的论坛找不到属于jasper.jar和jsp-api.jar的常见错误的类/文件错误，两者都在Tomcat中找到。< / em>的

无论如何，我愿意尝试使用或不涉及Tomcat的安装选项。如果有人在Windows上使用MySQL数据库安装XWiki取得了成功，那么非常感谢您的帮助！

Answer 1

看起来你错过了mysql驱动程序。由于您将默认分发转换为使用mysql，因此您需要下载mysql driver jar并将其部署到'webapps \ xwiki \ WEB-INF \ lib'目录。

关于第二个问题，数据库驱动程序错误，xar和tomcat 404之间可能没有任何关联.xar只是用于导入或导出内容和功能的页面集合，但通常不会处理低数据库连接等级别的东西。 Tomcat中的404可能是因为您访问了无效的URL。可能需要更多关于那个的细节。

Answer 2

首先关于与Tomcat的潜在冲突，我可以向你保证这是不可能的，因为Tomcat是XWiki团队一直在生产中使用的。

现在对于MySQL来说，错误非常明显，如果你真的把MySQL连接器放在了正确的位置，那么你就没有把它放到正确的地方。你放了什么版本的版本，是#xwiki folder#/WEB-INF/lib/？

XAR包不是安装XWiki的另一种方式，它是一个包含wiki页面的包，可以在XWiki运行时导入。也许你的意思是WAR包？

Answer 3

几个月前就解决了这个问题。我在设置中遗漏了一些重要信息，但现在工作正常。
