当我在ubuntu 12 / JDK7上运行tomcat7.0_26(在VM /虚拟机上运行)时,我不断收到有关日志目录中catalina.out文件中的DataSourceFactory的错误信息。有什么想法可以解决这个问题吗?我也复制了下面的相关server.xml和context.xml部分。我可以使用提供的用户名/密码组合连接到postgres数据库。
server.xml中:
<Resource type="javax.sql.DataSource"
name="jdbc/DB"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://localhost:5432/DBName"
username="database-user"
password="database-user-pwd"
testWhileIdle="true"
testOnBorrow="true"
testOnReturn="false"
validationQuery="SELECT 1"
validationInterval="30000"
timeBetweenEvictionRunsMillis="30000"
maxActive="100"
minIdle="10"
maxWait="10000"
initialSize="10"
removeAbandonedTimeout="60"
removeAbandoned="true"
logAbandoned="true"
minEvictableIdleTimeMillis="30000"
jmxEnabled="true"
context.xml中
<Context>
<!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<!-- Uncomment this to disable session persistence across Tomcat restarts -->
<!--
<Manager pathname="" />
-->
<!-- Uncomment this to enable Comet connection tacking (provides events
on session expiration as well as webapp lifecycle) -->
<!--
<Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
-->
<ResourceLink type="javax.sql.DataSource"
name="jdbc/DB"
global="jdbc/DB"/>
</Context>

您似乎错过了jar文件tomcat-jdbc.jar
。默认情况下,它不包含在标准Debian / Ubuntu软件包中。您可以从Maven Central下载。
