Question

我正在尝试将Websphere Liberty v16.0.0.4连接到HANA数据源，但是找不到正确的驱动程序。
当前在我的 server.xml 中，我具有以下内容：

<xml version="1.0" encoding="UTF-8">
<server description="o01-cls-pega-static-prpc02-appsrv03">

    <!-- Enable features -->

    <httpEndpoint id="defaultHttpEndpoint"
                  host="localhost"
                  httpPort="28740"
                  httpsPort="28741" />

    <!-- JDBC Hana Driver -->
    <jdbcDriver id="myHanaDriver" javax.sql.DataSource="com.ibm.ws.jdbc.jdbcDriver">
        <library>
            <fileset dir="${wlp.user.dir}/shared/resources/hana" includes="*.jar" id="HANALib"/>
        </library>
    </jdbcDriver>
    <!-- HANA JDBC Databases -->
    <dataSource
              type="javax.sql.DataSource"
              containerAuthDataRef="PegaDBUserSAPHANA"
              id="hanaDataSource"
              jdbcDriverRef="myHanaDriver"
              jndiName="jdbc/hanaDataSource">
    <properties serverName="localhost" port="35315"/>
    </dataSource>
    <applicationManager autoExpand="true"/>
</server>

这是我得到的错误：

[5/6/19 14:24:24:735 CEST] 00000038 LogService-156-com.ibm.ws.jdbc 
E CWWKE0701E: FrameworkEvent ERROR Bundle:com.ibm.ws.jdbc(id=156) org.osgi.framework.ServiceException:

任何能帮助我获得我所需的正确实现类的人吗？

Answer 1

您正确的配置了javax.sql.DataSource="com.ibm.ws.jdbc.jdbcDriver"。这应该指向JDBC驱动程序的javax.sql.DataSource实现，例如javax.sql.DataSource="com.sap.dbtech.jdbcext.DataSourceSapDB" 或者，对于许多JDBC驱动程序，如果完全省略了此配置属性，则新版本的Liberty（但不是此问题要求的较早的16.0.0.4级别）通常能够推断出正确的实现类。

Answer 2

我现在可以正常使用了，我对此进行了更改： javax.sql.DataSource =“ com.ibm.ws.jdbc.jdbcDriver” 进入 javax.sql.ConnectionPoolDataSource =“ com.sap.db.jdbcext.ConnectionPoolDataSourceSAP”

然后在此type =“ javax.sql.ConnectionPoolDataSource”中输入=“ javax.sql.DataSource”。

在Websphere Liberty中找不到Hana的有效JDBC驱动程序（实现类）
