不再正式支持嵌入elasticsearch，它比2.x中的要复杂一些，但可以。
您需要添加一些依赖项：
<dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>5.1.1</version> <scope>test</scope> </dependency> <dependency><!-- required by elasticsearch --> <groupId>org.elasticsearch.plugin</groupId> <artifactId>transport-netty4-client</artifactId> <version>5.1.1</version> <scope>test</scope> </dependency> <dependency><!-- required by elasticsearch --> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-api</artifactId> <version>2.7</version> </dependency>
然后启动一个这样的节点：
@Beanpublic Node elasticSearchTestNode() throws NodevalidationException { Node node = new MyNode( Settings.builder() .put("transport.type", "netty4") .put("http.type", "netty4") .put("http.enabled", "true") .put("path.home", "elasticsearch-data") .build(), asList(Netty4Plugin.class)); node.start(); return node;}private static class MyNode extends Node { public MyNode(Settings preparedSettings, Collection<Class<? extends Plugin>> classpathPlugins) { super(InternalSettingsPreparer.prepareEnvironment(preparedSettings, null), classpathPlugins); }}
