  1. POSolr 4.2 EmbeddedSolrServer can not load existing index data
    text
    copied!<p>I'm extending Solr's <strong>AbstractSolrTestCase</strong> for unit testing.</p> <p>I have existing 'schema.xml', 'solrconfig.xml' and index data. I can start an embedded solr server to load existing collection and its data. Then test searching doc in solr.</p> <p>Those test files(solr conf and data index) still work with Solr 4.2. I can launch a solr server in command line, and successfully query doc via admin page.</p> <blockquote> <p>java -Dsolr.solr.home=/somewhere/testdata/solr -jar start.jar</p> </blockquote> <p>However this way does not work any more after adapting to Solr 4.2.1. After some investigating, I found it looks like the index data is not loaded by solr's EmbeddedSolrServer.</p> <p>Does anybody know how to let EmbeddedSolrServer load the existing index data?</p> <p>I'm using below code to create embedded server for unit testing. In below code I'm using index data from solr official example.</p> <pre><code>public class IntegrationSolrTest2 extends AbstractSolrTestCase { private static final String CORE_NAME = "collection1"; private static File solrTestHome = new File( "/Users/kane/Downloads/solr-4.2.1/example/solr"); private static File confHome = new File(solrTestHome, CORE_NAME + "/conf"); private static File indexFile = new File(confHome.getParentFile(), "data/index"); private SolrServer server; @Override public String getSolrHome() { return solrTestHome.getAbsolutePath(); } final String configFile = new File(confHome, "solrconfig.xml") .getAbsolutePath(); // Creates a container based on infos needed to create one core static class Initializer extends CoreContainer.Initializer { String coreName; String dataDirectory; SolrConfig solrConfig; IndexSchema indexSchema; public Initializer(String coreName, String dataDirectory, SolrConfig solrConfig, IndexSchema indexSchema) { if (coreName == null) coreName = CoreContainer.DEFAULT_DEFAULT_CORE_NAME; this.coreName = coreName; this.dataDirectory = dataDirectory; this.solrConfig = solrConfig; this.indexSchema = indexSchema; } public String getCoreName() { return coreName; } @Override public CoreContainer initialize() { CoreContainer container = new CoreContainer(new SolrResourceLoader( SolrResourceLoader.locateSolrHome())) { { hostPort = System.getProperty("hostPort"); hostContext = "solr"; defaultCoreName = coreName; initShardHandler(null); initZooKeeper(System.getProperty("zkHost"), 10000); } }; LogWatcher&lt;?&gt; logging = new JulWatcher("test"); logging.registerListener(new ListenerConfig(), container); container.setLogging(logging); CoreDescriptor dcore = new CoreDescriptor(container, coreName, solrConfig.getResourceLoader().getInstanceDir()); dcore.setConfigName(solrConfig.getResourceName()); dcore.setSchemaName(indexSchema.getResourceName()); SolrCore core = new SolrCore(coreName, dataDirectory, solrConfig, indexSchema, dcore); container.register(coreName, core, false); // TODO: we should be exercising the *same* core container // initialization code, not equivalent code! if (container.getZkController() == null &amp;&amp; core.getUpdateHandler().getUpdateLog() != null) { // always kick off recovery if we are in standalone mode. core.getUpdateHandler().getUpdateLog().recoverFromLog(); } return container; } } @Before public void prepare() throws Exception { super.setUp(); solrConfig = TestHarness.createConfig(solrTestHome.getAbsolutePath(), CORE_NAME, configFile); h = new TestHarness(IntegrationSolrTest2.CORE_NAME, new Initializer( IntegrationSolrTest2.CORE_NAME, indexFile.getParentFile() .getAbsolutePath(), solrConfig, new IndexSchema( solrConfig, getSchemaFile(), null))); server = new EmbeddedSolrServer(h.getCoreContainer(), h.getCore() .getName()); h.getCoreContainer().reload(CORE_NAME); } @After public void cleanup() { h.getCoreContainer().shutdown(); } @Test public void searchAll() throws Exception { h.reload(); SolrQuery params = new SolrQuery(); params.setQuery("*:*"); QueryResponse response = server.query(params); final SolrDocumentList results = response.getResults(); assertTrue("Not search the expected goods!", results.getNumFound() &gt; 0); } } </code></pre>
