The SolrOxmClient provides for easier client communication with Apache Solr.
It marshalls/unmarshalls searches and updates to and from a JavaBean. It also allows calls to commit, rollback, and optimize.
It is built on top of HttpClientTemplate and HttpClientOxmTemplate.

|---|---|
The Spring configuration and code are from the Solr Client example and are not part of this module. |
A base URL to Solr and a marshaller and unmarshaller must be defined to use it. To read more about the test look at the Solr Client example.
<bean id="solrOxmClient" class="org.springbyexample.httpclient.solr.SolrOxmClient"
p:baseUrl="http://${solr.host}:${solr.port}/solr"
p:marshaller-ref="catalogItemMarshaller"
p:unmarshaller-ref="catalogItemMarshaller" />
Example 10. Excerpt from SolrOxmClientTest.testSearch()
Any Solr search parameter can be passed in and the results are unmarshalled into a specific JavaBean.
List<CatalogItem> lCatalogItems = client.search(SEARCH_QUERY_PARAM);
Example 11. Excerpt from SolrOxmClientTest.testPaginatedSearch()
To pass in other parameters to the search, a Map can
be passed in. The query is specified by the 'q' key, and
the 'start' & 'rows' indicate what range of the results to return.
Map<String, String> hParams = new HashMap<String, String>();
hParams.put("q", "electronics");
hParams.put("start", "5");
hParams.put("rows", "5");
List<CatalogItem> lCatalogItems = client.search(hParams);
Example 12. Excerpt from SolrOxmClientTest.testUpdate()
Updates a list of CatalogItem instances.
client.update(lCatalogItems);
