如何安装postgresqljdbc以在Karaf OSGi中工作？

我想在Karaf中安装org.postgresql/postgresql/9.4-1201-jdbc41，但出现错误。如何解决这些错误？奇怪的是，在Windows上，我的Karaf在Postgres jdbc上没有错误，但在Ubuntu上却有这些错误。任何线索都很感激

我在卡拉夫日志中查看了日志级别的信息

刚刚用Karaf 4.0.0.M2进行了测试： OSGi概要导出org.OSGi.service.jdbc

Apache Karaf数据源（JDBC）是可选的企业功能。为了安装postgresql，请使用以下语句

上述解决方案在Karaf 4.0.1上进行了测试，将Postgresql JDBC驱动程序配置到Karaf 4.0.1

在KARAF_HOME/etc/org.ops4j.datasource-companymanager.cfg下创建文件 其中，

companymanager

是数据源名称

osgi.jdbc.driver.name=PostgreSQL JDBC Driver-pool-xa

serverName=localhost
databaseName=companymanager
portNumber=5432
user=postgres
password=admin
dataSourceName=companymanager

瞧，完成后，您的数据源将暴露在OSGI注册表中，随时可供您使用：

karaf@root()> service:list javax.sql.DataSource
[javax.sql.DataSource]
----------------------
 databaseName = companymanager
 dataSourceName = companymanager
 felix.fileinstall.filename = file:/C:/apache-karaf-4.0.1/etc/org.ops4j.datasource-companymanager.cfg
 osgi.jdbc.driver.name = PostgreSQL JDBC Driver-pool-xa
 osgi.jndi.service.name = companymanager
 password = admin
 portNumber = 5432
 serverName = localhost
 service.bundleid = 64
 service.factoryPid = org.ops4j.datasource
 service.id = 119

下一步可能是设置JPA，如果您感兴趣，可以继续阅读并从以下位置获取完整的示例代码：
