Maven users will need to add the following dependency to their {{pom.xml}} for this component: ... |allowCompression|false|server side must support gzip or deflate for this to have any effect| |requestHandler|/update (xml)|set the request handler to be used| |streamingThreadCount|2|*Camel 2.10* set the number of threads for the [StreamingUpdateSolrServer|http://lucene.apache.org/solr/api/org/apache/solr/client/solrj/impl/StreamingUpdateSolrServer.html]| |streamingQueueSize|10|*Camel 2.10* set the queue size for the [StreamingUpdateSolrServer|http://lucene.apache.org/solr/api/org/apache/solr/client/solrj/impl/StreamingUpdateSolrServer.html]| h3.

Full Content Solr Component Available as of Camel 2.9 The Solr component allows you to interface with an Apache Lucene Solr server (based on SolrJ 3.5.0). Maven users will need to add the following dependency to their pom.xml for this component: <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-solr</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency> URI format solr://host[:port]/solr?[options] Endpoint Options The following SolrServer options may be configured on the Solr endpoint. name default value description maxRetries 0 maximum number of retries to attempt in the event of transient errors soTimeout 1000 read timeout on the underlying HttpConnectionManager. This is desirable for queries, but probably not for indexing connectionTimeout 100 connectionTimeout on the underlying HttpConnectionManager defaultMaxConnectionsPerHost 2 maxConnectionsPerHost on the underlying HttpConnectionManager maxTotalConnections 20 maxTotalConnection on the underlying HttpConnectionManager followRedirects false indicates whether redirects are used to get to the Solr server allowCompression false server side must support gzip or deflate for this to have any effect requestHandler /update (xml) set the request handler to be used streamingThreadCount 2 Camel 2.10 set the number of threads for the StreamingUpdateSolrServer streamingQueueSize 10 Camel 2.10 set the queue size for the StreamingUpdateSolrServer Message Operations The following Solr operations are currently supported. Simply set an exchange header with a key of "SolrOperation" and a value set to one of the following. Some operations also require the message body to be set. operation message body description INSERT empty adds an index using message headers (must be prefixed with "SolrField.") INSERT SolrInputDocument Camel 2.10 adds an index based on the given SolrInputDocument INSERT_STREAMING empty Camel 2.10 uses the StreamingUpdateSolrServer to add an index using message headers (must be prefixed with "SolrField.") INSERT_STREAMING SolrInputDocument Camel 2.10 uses the StreamingUpdateSolrServer to add an index based on the given SolrInputDocument ADD_BEAN bean instance adds an index based on values in an annotated bean DELETE_BY_ID index id to delete delete a record by ID DELETE_BY_QUERY query string delete a record by a query COMMIT n/a performs a commit on any pending index changes ROLLBACK n/a performs a rollback on any pending index changes OPTIMIZE n/a performs a commit on any pending index changes and then runs the optimize command Example Below is a simple INSERT and COMMIT example from("direct:insert") .setHeader(SolrConstants.OPERATION, constant(SolrConstants.OPERATION_INSERT)) .setHeader(SolrConstants.FIELD + "id", body()) .to("solr://localhost:8983/solr"); from("direct:commit") .setHeader(SolrConstants.OPERATION, constant(SolrConstants.OPERATION_COMMIT)) .to("solr://localhost:8983/solr"); <route> <from uri="direct:insert"/> <setHeader headerName="SolrOperation"> <constant>INSERT</constant> </setHeader> <setHeader headerName="SolrField.id"> <simple>${body}</simple> </setHeader> <to uri="solr://localhost:8983/solr"/> </route> <route> <from uri="direct:commit"/> <setHeader headerName="SolrOperation"> <constant>COMMIT</constant> </setHeader> <to uri="solr://localhost:8983/solr"/> </route> A client would simply need to pass a body message to the insert route and then call the commit route. template.sendBody("direct:insert", "1234"); template.sendBody("direct:commit", null); Querying Solr Currently, this component doesn't support querying data natively (may be added later). For now, you can query Solr using HTTP as follows: //define the route to perform a basic query from("direct:query") .recipientList(simple("http://localhost:8983/solr/select/?q=${body}")) .convertBodyTo(String.class); ... //query for an id of '1234' (url encoded) String responseXml = (String) template.requestBody("direct:query", "id%3A1234"); For more information, see these resources...
