我在尝试让Solr与在我的本地MAMP安装上运行的MySQL连接以进行数据导入时遇到问题。
我已经设置了我的data-config.xml文件：
<dataConfig>
<dataSource type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:8889/***"
user="root"
password="root"
batchSize="-1"
readOnly="true" />
<document>
<entity name="id" query="SELECT show_id AS 'id', name, description FROM ***;">
<field column="show_id" name="id" />
<field column="name" name="name" />
<field column="description" name="description" />
</entity>
</document>
</dataConfig>
我还在solrconfig.xml文件中添加了以下内容：
<lib dir="../../../libexec/contrib/dataimporthandler/lib" regex=".*\.jar" />
<lib dir="../../../libexec/dist/" regex="solr-dataimporthandler-.*\.jar" />
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">db-data-config.xml</str>
</lst>
</requestHandler>
<lib dir="../../../libexec/dist/mysql/" regex="mysql-connector-java-\d.*\.jar" />
我运行以下操作来进行数据导入：
http://localhost:8983/solr/collection1/dataimport?command=full-import&debug=true&verbose=true
但我得到以下内容：
org.apache.solr.handler.dataimport.DataImportHandlerException: Unable to execute query: SELECT show_id AS 'id', name, description FROM tbl_hbo_shows; Processing Document # 1 at org.apache.solr.handler.dataimport.DataImportHandlerException.wrapAndThrow(DataImportHandlerException.java:71) at org.apache.solr.handler.dataimport.JdbcDataSource$ResultSetIterator.<init>(JdbcDataSource.java:283) at org.apache.solr.handler.dataimport.JdbcDataSource.getData(JdbcDataSource.java:240) at org.apache.solr.handler.dataimport.JdbcDataSource.getData(JdbcDataSource.java:44) at org.apache.solr.handler.dataimport.DebugLogger$2.getData(DebugLogger.java:188) at org.apache.solr.handler.dataimport.SqlEntityProcessor.initQuery(SqlEntityProcessor.java:59) at org.apache.solr.handler.dataimport.SqlEntityProcessor.nextRow(SqlEntityProcessor.java:73) at org.apache.solr.handler.dataimport.EntityProcessorWrapper.nextRow(EntityProcessorWrapper.java:243) at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:476) at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:415) at org.apache.solr.handler.dataimport.DocBuilder.doFullDump(DocBuilder.java:330) at org.apache.solr.handler.dataimport.DocBuilder.execute(DocBuilder.java:232) at org.apache.solr.handler.dataimport.DataImporter.doFullImport(DataImporter.java:416) at org.apache.solr.handler.dataimport.DataImporter.runCmd(DataImporter.java:480) at org.apache.solr.handler.dataimport.DataImportHandler.handleRequestBody(DataImportHandler.java:189) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:135) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1967) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:777) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:418) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:207) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1419) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:455) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:137) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:557) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:231) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1075) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:384) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:193) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1009) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:135) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:255) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:154) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:116) at org.eclipse.jetty.server.Server.handle(Server.java:368) at org.eclipse.jetty.server.AbstractHttpConnection.handleRequest(AbstractHttpConnection.java:489) at org.eclipse.jetty.server.BlockingHttpConnection.handleRequest(BlockingHttpConnection.java:53) at org.eclipse.jetty.server.AbstractHttpConnection.headerComplete(AbstractHttpConnection.java:942) at org.eclipse.jetty.server.AbstractHttpConnection$RequestHandler.headerComplete(AbstractHttpConnection.java:1004) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:640) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:235) at org.eclipse.jetty.server.BlockingHttpConnection.handle(BlockingHttpConnection.java:72) at org.eclipse.jetty.server.bio.SocketConnector$ConnectorEndPoint.run(SocketConnector.java:264) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:608) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:543) at java.lang.Thread.run(Thread.java:745) Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago.

我正在使用MAMP Pro运行Solr 4.10.2来处理MySQL数据库连接。我已经在线查看了各种类似的问题但是我的连接URL等的更改似乎没有解决问题。
感谢您的帮助。

我通过最终发现我收到错误来修复它：
成功发送到服务器的最后一个数据包是0毫秒前。驱动程序未收到来自服务器的任何数据包。
