我正试图在karaf 4.2.2环境中使用camel bundle camel-elasticsearch-rest 2.22.2。
当我安装camel bundle camel-elasticsearch-rest时一切顺利，它会自动安装它的依赖项（screenshot of camel-elasticsearch-rest install bundle in karaf）：
在我的代码中，我用这种方式调用camel-elasticsearch-rest：
import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
public class ServiceRouteBuilder extends RouteBuilder {
@Override
public void configure() throws Exception {
CamelContext context = this.getContext();
restConfiguration()
.component("jetty")
.host("localhost")
.port(8200)
.contextPath("/api")
.dataFormatProperty("prettyPrint", "true")
.apiProperty("cors", "true");
rest("/elastic/test")
.get("/")
.route()
.setBody(simple("{ \"indexName\": \"test-index\" }"))
.to("elasticsearch-rest://elasticsearch?hostAddresses=127.0.0.1:9200&operation=INDEX&indexName=test-index&indexType=sample");
}
}
我已经在karaf上安装了我的jar包，但是当驼峰上下文启动时，我收到此警告，导致驼峰路由关闭：

我的问题是为什么org.apache.servicemix.bundles.elasticsearch-client找不到类org.apache.http.client.AuthCache。
该类应该在karaf上正确安装的依赖项org.apache.httpcomponents.httpclient中。
我已经看到在org.apache.servicemix.bundles.elasticsearch-client包中没有导入的包（screenshot of the imported packages），这是正常的吗？这是一个错误，或者我错过了什么？
KARAF（OSGi）不支持elasticsearch-client
关于elasticsearch-client OSGi支持的讨论：https://github.com/elastic/elasticsearch/issues/28707
但是你可以将它构建为OSGi包，如下所述：Howto: osgi and shared packages?
